This dissertation presents a computational framework that leverages machine learning, computer vision, large\u2010language models, and novel mathematical methods to extract, analyze, and interpret leaf traits at scale. By combining lineage\u2010specific approaches with broad comparative analyses, it establishes procedures for measuring traits across these vast datasets.\r\nChapter 2 introduces LeafMachine2, a modular machine\u2010learning pipeline that automates quantitative trait extraction from digitized herbarium specimens. Trained on nearly half a million manual annotations from over two thousand species, LeafMachine2 employs multiple neural networks to detect and segment individual leaves, recognize rulers and labels, and identify pseudo\u2010landmarks such as midvein length, petiole length, and lobe positions. This tool processes thousands of images per hour, calculates pixel\u2010to\u2010metric conversion factors for most common scalebar types, and generates standardized measurements (area, perimeter, Fourier descriptors, and landmark\u2010based metrics) even when specimens contain occluded or overlapping leaves. By automating leaf extraction and measurement procedures, LeafMachine2 removes a bottleneck in morphological data acquisition and lays the foundation for large\u2010scale analyses.\r\nChapter 3 presents FieldPrism, a versatile hardware and software suite designed to extend quantitative trait collection to field photographs. FieldPrism employs a photogrammetric background template (FieldSheet) containing machine\u2010readable scale markers and optional QR codes for specimen identification. Coupled with a Raspberry Pi-based mobile imaging apparatus (FieldStation), FieldPrism automatically corrects image distortion, computes pixel\u2010to\u2010metric conversion, decodes QR codes to assign meaningful file names, and embeds GPS metadata. Validation tests across smartphone, mirrorless, and machine\u2010vision cameras demonstrate high accuracy in scale conversion and reliable QR code decoding at typical working distances. FieldPrism enables the creation of \u201csnapshot vouchers\u201d that complement physical voucher specimens, opening new possibilities for citizen science and field\u2010based trait collection.\r\nChapter 4 explores the integration of large language models (LLMs) into herbarium label transcription. VoucherVision combines optical character recognition with LLM\u2010based parsing to transform unstructured OCR text into structured spreadsheet entries. In practice, VoucherVision increased transcription productivity by 25 percent over manual workflows. This chapter also examines potential risks like job displacement, copyright and data sovereignty issues, model permanence, and outlines a collaborative benchmarking initiative to develop fine\u2010tuned, community\u2010driven LLM solutions that respect data ownership and ensure reproducibility.\r\nChapter 5 applies LeafMachine2, Euler characteristic transform (ECT), and a novel geomorphon\u2010based classification to analyze 4.6 million individual leaf outlines from nearly half a million herbarium specimens, covering 12 angiosperm families and close to seven thousand species. ECT matrices capture topological signatures of each leaf outline, while geomorphon analysis distills leaf margin features into continuous and categorical metrics that quantify toothedness and lobedness. By integrating WorldClim bioclimatic layers with dated phylogenies and analyzing the dataset using linear mixed-effects and phylogenetic regression models, I demonstrate that the canonical climate\u2013leaf trait associations\u2014larger, entire-margined leaves in warmer, wetter environments and more toothed or lobed leaves in cooler, drier locations\u2014are clade-specific rather than universal across angiosperms. Instead, family\u2010 and genus\u2010specific evolutionary regimes emerge. Phylogenetic correction often weakens climate-leaf area associations while strengthening leaf shape associations with minimum temperatures. Correlated\u2010trait analyses reveal that margin\u2010type evolution is climate\u2010dependent in some woody clades but independent in many herbaceous groups. Overall, leaf traits are shaped by a dynamic interaction of developmental constraints, phylogenetic history, growth habit, and climate.\r\nThis dissertation demonstrates that integrating machine learning, artificial intelligence, and innovative mathematical approaches transform digitized herbarium specimens into a rigorous analytical foundation for addressing foundational questions in leaf evolution and biogeography. Providing scalable, streamlined workflows that operate at previously unattainable scales, these contributions enable researchers to move beyond isolated case studies and achieve a holistic synthesis of how environment, development, and phylogenetic history interact to generate the extraordinary diversity of angiosperm leaf forms.", "occurrence_notes":null, "guid":"136318-21878493@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/136318", "building_id":"1005169", "building_name":"Biological Sciences Building", "building_official_id":1005169, "campus_maps_id":"631", "campus_maps_link_path":"biological-sciences-building", "campus_maps_link":"https:\/\/maps.studentlife.umich.edu\/building\/biological-sciences-building", "room":"3150", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["department of ecology and evolutionary biology"], "website":"", "links":[ ], "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"EEB Defenses", "group_id":"3821", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/07\/event_136318_original-1.jpg", "image_description":"Event poster", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2025\/07\/event_136318_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2025\/07\/event_136318_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/07\/event_136318_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/07\/event_136318_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2025\/07\/event_136318_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2025\/07\/event_136318_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2025\/07\/event_136318_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2025\/07\/event_136318_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2025\/07\/event_136318_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2025\/07\/event_136318_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/07\/event_136318_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/07\/event_136318_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2025\/07\/event_136318_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2025\/07\/event_136318_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2025\/07\/event_136318_original-1.jpg" }, "qr_code_url":"http:\/\/events.umich.edu\/event\/136318\/qrcode.png", "occurrence_count":1, "first_occurrence":21878493 } , { "id":"136404-21878620", "datetime_modified":"20250709T152620", "datetime_start":"20250715T120000", "datetime_end":"20250715T130000", "has_end_time":1, "date_start":"2025-07-15", "date_end":"2025-07-15", "time_start":"12:00:00", "time_end":"13:00:00", "time_zone":"America\/Detroit", "event_title":"EEB Prelim Seminar Series - Microbial legacies: effects on community structure, function, and response dynamics", "occurrence_title":"", "combined_title":"EEB Prelim Seminar Series - Microbial legacies: effects on community structure, function, and response dynamics: Kathryn Schmidt, Ph.D. student EEB, Denef lab", "event_subtitle":"Kathryn Schmidt, Ph.D. student EEB, Denef lab", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Abstract:\r\nLinking community structure to ecological function is a primary goal of community ecology. In microbial ecology, advances in sequencing technology have allowed widespread profiling of community structure, and putative functions. However, whether such descriptive characterization has improved our ability to predict and model microbial response dynamics remains unclear. Structure-function relationships are particularly convoluted in microbial systems due to high levels of genetic diversity, metabolic plasticity, context dependency, and widespread functional redundancy. To this end, a wide body of research has shown that past events or historical community states can affect contemporary communities. However, the ways in which legacy effects influence microbial diversity patterns and response dynamics, particularly in the face of anthropogenic disturbance regimes, remains poorly understood. Using both an observational and experimental approach, my research aims to identify the signatures of legacy effects on microbial trait distributions, and assess whether these effects constrain or augment community response trajectories. Focusing on both soil and freshwater ecosystems, my research will investigate legacy effects from agricultural management practices and lake eutrophication, two major drivers of global change. Additionally, I will explore whether trait distributions and response patterns observed in the laboratory scale up to reflect those observed in a natural ecosystem, affected by these stressors. Broadly, my research will contribute to the overall understanding of the factors driving variation in microbial community structure, and the role of past environmental states or selection regimes play in community functional stability.", "occurrence_notes":"3150", "guid":"136404-21878620@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/136404", "building_id":"1005169", "building_name":"Biological Sciences Building", "building_official_id":1005169, "campus_maps_id":"631", "campus_maps_link_path":"biological-sciences-building", "campus_maps_link":"https:\/\/maps.studentlife.umich.edu\/building\/biological-sciences-building", "room":"", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["department of ecology and evolutionary biology"], "website":"", "links":[ ], "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"EEB Tuesday Lunch Seminars", "group_id":"3823", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/07\/event_136404_original-1.jpg", "image_description":"Event poster", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2025\/07\/event_136404_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2025\/07\/event_136404_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/07\/event_136404_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/07\/event_136404_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb\/media\/attachments\/2025\/07\/event_136404_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb_square\/media\/attachments\/2025\/07\/event_136404_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large\/media\/attachments\/2025\/07\/event_136404_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large_lightbox\/media\/attachments\/2025\/07\/event_136404_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_crop\/media\/attachments\/2025\/07\/event_136404_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_list\/media\/attachments\/2025\/07\/event_136404_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/07\/event_136404_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/07\/event_136404_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_grid_2x\/media\/attachments\/2025\/07\/event_136404_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_large\/media\/attachments\/2025\/07\/event_136404_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_thumb\/media\/attachments\/2025\/07\/event_136404_original-1.jpg" }, "qr_code_url":"http:\/\/events.umich.edu\/event\/136404\/qrcode.png", "occurrence_count":1, "first_occurrence":21878620 } , { "id":"138095-21881948", "datetime_modified":"20250825T155354", "datetime_start":"20250828T100000", "datetime_end":"20250828T110000", "has_end_time":1, "date_start":"2025-08-28", "date_end":"2025-08-28", "time_start":"10:00:00", "time_end":"11:00:00", "time_zone":"America\/Detroit", "event_title":"EEB Student Dissertation Defense - Divergence in Gene Expression Plasticity", "occurrence_title":"", "combined_title":"EEB Student Dissertation Defense - Divergence in Gene Expression Plasticity: Anna Redhuis, EEB PhD Student, Wittkopp Lab", "event_subtitle":"Anna Redhuis, EEB PhD Student, Wittkopp Lab", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Defense Preview:\r\nOrganisms respond to shifts in their environment by changing the abundance of different mRNA transcripts in their cells, a process called \"gene expression plasticity\". We understand that gene expression plasticity itself can evolve---the same environmental shift can cause different patterns of gene expression plasticity in different genetic backgrounds. We don't, however, know much about how gene expression plasticity tends to evolve. Is divergence in gene expression plasticity common between closely related species? Are certain genes more or less likely to experience evolutionary changes to their patterns of expression plasticity? In this dissertation defense, I characterize gene expression plasticity divergence in two yeast species: the baker's yeast Saccharomyces cerevisiae and one of its closest related species, Saccharomyces paradoxus. To describe the extent of gene expression plasticity divergence, I cluster gene expression responses to six different environments. I find that each of the six environments identifies a unique set of at least 100 genes that have diverged in gene expression plasticity. Interestingly, the genes most likely to experience this expression plasticity divergence are the genes with the fewest connections in the regulatory network. My work demonstrates that different environments can reveal hidden dimensions of molecular evolution, and that network connectivity is associated with more robust expression plasticity over evolutionary time.", "occurrence_notes":null, "guid":"138095-21881948@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/138095", "building_id":"1005169", "building_name":"Biological Sciences Building", "building_official_id":1005169, "campus_maps_id":"631", "campus_maps_link_path":"biological-sciences-building", "campus_maps_link":"https:\/\/maps.studentlife.umich.edu\/building\/biological-sciences-building", "room":"1010", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["department of ecology and evolutionary biology"], "website":"", "links":[ ], "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"EEB Defenses", "group_id":"3821", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/08\/event_138095_original-1.jpg", "image_description":"Event poster", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_thumb\/media\/attachments\/2025\/08\/event_138095_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2025\/08\/event_138095_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/08\/event_138095_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/08\/event_138095_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb\/media\/attachments\/2025\/08\/event_138095_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb_square\/media\/attachments\/2025\/08\/event_138095_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large\/media\/attachments\/2025\/08\/event_138095_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large_lightbox\/media\/attachments\/2025\/08\/event_138095_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_crop\/media\/attachments\/2025\/08\/event_138095_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_list\/media\/attachments\/2025\/08\/event_138095_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/08\/event_138095_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/08\/event_138095_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_grid_2x\/media\/attachments\/2025\/08\/event_138095_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_large\/media\/attachments\/2025\/08\/event_138095_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_thumb\/media\/attachments\/2025\/08\/event_138095_original-1.jpg" }, "qr_code_url":"http:\/\/events.umich.edu\/event\/138095\/qrcode.png", "occurrence_count":1, "first_occurrence":21881948 } , { "id":"138156-21882412", "datetime_modified":"20250827T095512", "datetime_start":"20250902T120000", "datetime_end":"20250902T130000", "has_end_time":1, "date_start":"2025-09-02", "date_end":"2025-09-02", "time_start":"12:00:00", "time_end":"13:00:00", "time_zone":"America\/Detroit", "event_title":"EEB Tuesday Seminar Series - Hetero-chaos in a Community of Ants in Puerto Rico", "occurrence_title":"", "combined_title":"EEB Tuesday Seminar Series - Hetero-chaos in a Community of Ants in Puerto Rico: John Vandermeer, Asa Gray Distinguished University Professor of EEB, Arthur F.

Therefore, the capacity to make appropriate decisions during host plant selection is a crucial behavioral trait of insect herbivores. Our research group investigated behavioral decisions by butterflies and bees that exploit ant-visited plants in the Cerrado savanna of Brazil. Observations and experiments were performed under contrasting ecological scenarios: antagonism and mutualism with ants. Field experiments show that detection of ants by these two groups of flying insects can either discourage or promote potential contact with ants on foliage. Interaction trials suggest that behavioral decisions are associated with the risk of ant-induced injury, or with the benefit of protection via ant mutualists. Visual recognition of aggressive ants represents an unusual case of behavioral adaptation by flying insects associated with the use of plant resources (leaves, flower rewards) on ant-occupied foliage, and is particularly relevant in ant-rich Cerrado.", "occurrence_notes":null, "guid":"138170-21882453@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/138170", "building_id":"1005169", "building_name":"Biological Sciences Building", "building_official_id":1005169, "campus_maps_id":"631", "campus_maps_link_path":"biological-sciences-building", "campus_maps_link":"https:\/\/maps.studentlife.umich.edu\/building\/biological-sciences-building", "room":"1060", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["department of ecology and evolutionary biology"], "website":"", "links":[ ], "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"EEB Thursday Seminars", "group_id":"3822", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/08\/event_138170_original-1.png", "image_description":"Event Poster", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2025\/08\/event_138170_original-1.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2025\/08\/event_138170_original-1.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/08\/event_138170_original-1.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/08\/event_138170_original-1.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2025\/08\/event_138170_original-1.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2025\/08\/event_138170_original-1.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2025\/08\/event_138170_original-1.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2025\/08\/event_138170_original-1.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2025\/08\/event_138170_original-1.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2025\/08\/event_138170_original-1.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/08\/event_138170_original-1.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/08\/event_138170_original-1.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2025\/08\/event_138170_original-1.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2025\/08\/event_138170_original-1.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2025\/08\/event_138170_original-1.png" }, "qr_code_url":"http:\/\/events.umich.edu\/event\/138170\/qrcode.png", "occurrence_count":1, "first_occurrence":21882453 } , { "id":"138594-21883423", "datetime_modified":"20250902T095554", "datetime_start":"20250908T133000", "datetime_end":"20250908T153000", "has_end_time":1, "date_start":"2025-09-08", "date_end":"2025-09-08", "time_start":"13:30:00", "time_end":"15:30:00", "time_zone":"America\/Detroit", "event_title":"EEB Student Dissertation Defense - Recovering the missing links: from genomic signatures to virus-host interaction networks", "occurrence_title":"", "combined_title":"EEB Student Dissertation Defense - Recovering the missing links: from genomic signatures to virus-host interaction networks: G.

Next-generation sequencing has accelerated virus discovery at an unprecedented rate, revealing vast viral diversity in the microbial world. However, this pace of discovery has created a critical knowledge gap: who do those viruses infect? This dissertation addresses this fundamental challenge by demonstrating that viral genomes contain detectable signatures of microbial host adaptation. Those genomic \"battle scars\" can be computationally decoded to predict virus-host interactions. Through analysis of these evolutionary fingerprints, this work shows that viral dependence on host cellular machinery creates measurable genomic signals that reflect specific adaptation patterns to their hosts. Leveraging these insights, a machine learning model was developed that predicts virus-host interactions with 92% accuracy. This tool, released as an open-source Python package, enables the mapping of virus-host interaction networks directly from sequence data. Application of this approach reveals the network architectures underlying virus-host interactions, with computational predictions compared with experimental approaches. Taken together, this body of work demonstrates how genomic signatures can be leveraged to predict virus-host ecological relationships, offering a new method for mapping virus-host networks from sequence data.\"", "occurrence_notes":null, "guid":"138594-21883423@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/138594", "building_id":"1005169", "building_name":"Biological Sciences Building", "building_official_id":1005169, "campus_maps_id":"631", "campus_maps_link_path":"biological-sciences-building", "campus_maps_link":"https:\/\/maps.studentlife.umich.edu\/building\/biological-sciences-building", "room":"1010", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["department of ecology and evolutionary biology"], "website":"", "links":[ ], "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"EEB Defenses", "group_id":"3821", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/09\/event_138594_original-1.jpg", "image_description":"Event poster", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_thumb\/media\/attachments\/2025\/09\/event_138594_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2025\/09\/event_138594_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/09\/event_138594_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/09\/event_138594_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb\/media\/attachments\/2025\/09\/event_138594_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb_square\/media\/attachments\/2025\/09\/event_138594_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large\/media\/attachments\/2025\/09\/event_138594_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large_lightbox\/media\/attachments\/2025\/09\/event_138594_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_crop\/media\/attachments\/2025\/09\/event_138594_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_list\/media\/attachments\/2025\/09\/event_138594_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/09\/event_138594_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/09\/event_138594_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_grid_2x\/media\/attachments\/2025\/09\/event_138594_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_large\/media\/attachments\/2025\/09\/event_138594_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_thumb\/media\/attachments\/2025\/09\/event_138594_original-1.jpg" }, "qr_code_url":"http:\/\/events.umich.edu\/event\/138594\/qrcode.png", "occurrence_count":1, "first_occurrence":21883423 } , { "id":"138694-21883628", "datetime_modified":"20250902T181756", "datetime_start":"20250909T120000", "datetime_end":"20250909T130000", "has_end_time":1, "date_start":"2025-09-09", "date_end":"2025-09-09", "time_start":"12:00:00", "time_end":"13:00:00", "time_zone":"America\/Detroit", "event_title":"EEB Tuesday Seminar Series: 1) Uncovering the Early Evolution of Canids from an Exceptional Skeleton of Mesocyon\/\/ 2) Reducing Plastic Waste in the Lab (Pt. 1!)", "occurrence_title":"", "combined_title":"EEB Tuesday Seminar Series: 1) Uncovering the Early Evolution of Canids from an Exceptional Skeleton of Mesocyon\/\/ 2) Reducing Plastic Waste in the Lab (Pt. 1!): Speakers: Dr. Anne Kort, Michigan Society of Fellows Postdoctoral Scholar\/\/ Dr. Jill Myers, EEB Biodiversity Lab Manager", "event_subtitle":"Speakers: Dr. Anne Kort, Michigan Society of Fellows Postdoctoral Scholar\/\/ Dr. Jill Myers, EEB Biodiversity Lab Manager", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"This week, we have two speakers for our Tuesday seminar! \r\nPlease read details below: \r\n\r\n1) Dr. Anne Kort, Michigan Society of Fellows Postdoctoral Scholar\r\n\r\nTitle: Uncovering the Early Evolution of Canids from an Exceptional Skeleton of Mesocyon\r\n\r\nDescription: Living members of the dog family, including wolves, foxes, and our own household pets, are well-adapted for running fast and far, with long legs and stabilized joints. These skeletal adaptations appear in many fossil relatives of dogs, especially in the last 15 million years when grasslands became more dominant on the landscape. But what did the earliest members of the dog family look like? Mesocyon coryphaeus is an early relative of modern dogs that lived in the Pacific Northwest of North America approximately 30 million years ago. Although this species has been known from skulls and teeth for over a century, the skeleton of Mesocyon has been essentially unknown through this time. A spectacular fossil of Mesocyon was discovered by John Day Fossil Beds National Monument staff in the late 1980s. After over 500 hours of preparation work on and off throughout the following decades, the near-complete skeleton of this animal was fully uncovered in 2022. This skeleton is close to a coyote in size but has short, robust limbs and relatively flexible joints, suggesting that Mesocyon was an ambush predator, unlike most modern canids.\r\n\r\n2) Dr. Jill Myers, biodiversity lab manager\r\n\r\nTitle: Reducing Plastic Waste in the Lab (Pt. 1!) \r\n\r\nDescription: Globally, research labs generate more than 12 billion pounds of plastic waste per year.

See information below: \r\n\r\nSpeaker 1: Jiachen Li, master's student, Department of Computational Medicine & Bioinformatics, Zhang Lab\r\n\r\nTitle: Chance and necessity in evolution: how repeatable is phenotypic evolution?\r\nDescription: Assessing the relative roles of chance and necessity in evolution is of wide interest, but it requires evolving the same population under the same environment multiple times\u2014a virtually impossible task in nature that has been repeatedly accomplished in the laboratory. Capitalizing on the transcriptome data collected from experimental evolution of replicated populations spanning distinct environments, I investigate the evolutionary repeatability of hundreds of thousands of gene expression traits in a prokaryotic and five eukaryotic species.\r\n\r\n\r\nSpeaker 2: Dr. Yang Li, EEB Postdoctoral Fellow, Zhang Lab.\r\n\r\nTitle: Navigability of thousands of adaptive landscapes of RNA and protein expressions by trans-regulatory mutations\r\nDescription: Gene expression evolution relies on regulatory mutations. Past studies showed that optimizing gene expression by positive selection on cis-regulatory mutations is relatively easy because the corresponding adaptive landscapes are quite smooth, but a comparable study of trans-regulatory mutations is lacking. Analyzing the transcriptomes and proteomes of 16 yeast strains carrying all combinations of four auxotrophic mutations, we respectively construct 5,923 and 446 adaptive landscapes of mRNA and protein expressions where neighboring genotypes differ by a trans-regulatory mutation. We find that mRNA expression is less optimizable by trans- than cis-mutations, which may partially explain why trans-changes are rarer than cis-changes in gene expression evolution. Interestingly, the protein expression landscapes are substantially more navigable than the mRNA expression landscapes, suggesting that, for protein-coding genes, the evolvability of gene expression is even higher than the current estimate from adaptive landscapes of mRNA expression. This high evolvability may have contributed to the prominence of gene expression changes as a mechanism of evolutionary adaptation.", "occurrence_notes":null, "guid":"139270-21885219@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/139270", "building_id":"1005169", "building_name":"Biological Sciences Building", "building_official_id":1005169, "campus_maps_id":"631", "campus_maps_link_path":"biological-sciences-building", "campus_maps_link":"https:\/\/maps.studentlife.umich.edu\/building\/biological-sciences-building", "room":"", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["department of ecology and evolutionary biology"], "website":"", "links":[ ], "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"EEB Tuesday Lunch Seminars", "group_id":"3823", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/09\/event_139270_original-1.jpg", "image_description":"Event poster", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2025\/09\/event_139270_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2025\/09\/event_139270_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/09\/event_139270_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/09\/event_139270_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb\/media\/attachments\/2025\/09\/event_139270_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb_square\/media\/attachments\/2025\/09\/event_139270_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large\/media\/attachments\/2025\/09\/event_139270_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2025\/09\/event_139270_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_crop\/media\/attachments\/2025\/09\/event_139270_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2025\/09\/event_139270_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/09\/event_139270_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/09\/event_139270_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_grid_2x\/media\/attachments\/2025\/09\/event_139270_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_large\/media\/attachments\/2025\/09\/event_139270_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_thumb\/media\/attachments\/2025\/09\/event_139270_original-1.jpg" }, "qr_code_url":"http:\/\/events.umich.edu\/event\/139270\/qrcode.png", "occurrence_count":1, "first_occurrence":21885219 } , { "id":"139706-21885932", "datetime_modified":"20250922T150041", "datetime_start":"20250930T120000", "datetime_end":"20250930T130000", "has_end_time":1, "date_start":"2025-09-30", "date_end":"2025-09-30", "time_start":"12:00:00", "time_end":"13:00:00", "time_zone":"America\/Detroit", "event_title":"EEB Tuesday Seminar Series - Color, Chemistry and Courtship: Exploring how pigmentation genes shape mating behavior in Drosophila", "occurrence_title":"", "combined_title":"EEB Tuesday Seminar Series - Color, Chemistry and Courtship: Exploring how pigmentation genes shape mating behavior in Drosophila: Ayushi Dasgupta, EEB PhD Student (Wittkopp Lab)", "event_subtitle":"Ayushi Dasgupta, EEB PhD Student (Wittkopp Lab)", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Description: Pleiotropy offers a unifying framework that reveals how seemingly unrelated traits can be linked through a single gene.

Many mutations that occur in genomes are deleterious, resulting in a decrease in reproductive fitness. While such mutations are important for evolution and complex traits, much remains to be discovered. In this talk, I will discuss our work on estimating fitness effects of deleterious mutations using genetic variation data from natural populations. First, I will describe our computational approach, FitDadi, to estimate the distribution of fitness effects (DFE) for amino acid changing mutations in humans and other species. Analysis of how the DFE differs across species provides insights about how the DFE itself evolves. I also will describe our work inferring the DFE of mutations in noncoding regions of the human genome. Next, I provide a strategy to validate population genetic models of selection and dominance by testing whether they predict observed levels of inbreeding load and match observed genetic data.

High-elevation, montane places, in particular, are being strongly impacted by warming temperatures, changing snowmelt, and species invasion. Though these global change processes are happening simultaneously, we know little about how they will interact to impact carbon cycling across different temporal scales. My dissertation addresses this research gap with three interrelated field experiments in montane meadows of Colorado and New Zealand. First, I worked in a long-term warming and dominant species removal experiment set at two elevations to measure how warming and dominant species removal impact subdominant plant biomass and the rate of biomass change across a growing season. Warming decreased subdominant plant biomass, and dominant species removal increased subdominant plant biomass at both elevations, consistently across the growing season. Biomass differences manifested in the first week of the growing season and persisted throughout the growing season, with no treatment effects on the growth rate of the plants, suggesting that early-season biomass conditions are important in determining overall plant biomass. Next, I investigated how warming interacted with an invasive dominant species to impact carbon cycling across the growing season in a montane grassland in New Zealand. Removal of the invasive dominant species reduced the productivity of the system, reducing the strength of the carbon sink. Though warming did not impact the productivity of the invaded plots, warming increased the productivity of the native plant community, suggesting that the native plant community could play an important role in maintaining productivity in future, warmer climate scenarios. Finally, I investigated how a shift in the early-season abiotic conditions, earlier snowmelt, might impact carbon cycling across the growing season in a montane meadow in Colorado. Earlier snowmelt increased the strength of the carbon sink, though unequally throughout the growing season. With earlier snowmelt, the growing season started earlier and increased carbon uptake through peak season. However, the late season had a weaker carbon sink, likely due to the earlier soil drying. Taken together, my dissertation reveals the many ways global change is likely to impact carbon cycling across temporal scales in highly sensitive montane environments.", "occurrence_notes":"1010", "guid":"140912-21887799@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/140912", "building_id":"1005169", "building_name":"Biological Sciences Building", "building_official_id":1005169, "campus_maps_id":"631", "campus_maps_link_path":"biological-sciences-building", "campus_maps_link":"https:\/\/maps.studentlife.umich.edu\/building\/biological-sciences-building", "room":"", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["department of ecology and evolutionary biology"], "website":"", "links":[ ], "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"EEB Defenses", "group_id":"3821", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/10\/event_140912_original-1.jpg", "image_description":"Event poster", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2025\/10\/event_140912_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2025\/10\/event_140912_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/10\/event_140912_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/10\/event_140912_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2025\/10\/event_140912_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2025\/10\/event_140912_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2025\/10\/event_140912_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2025\/10\/event_140912_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2025\/10\/event_140912_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2025\/10\/event_140912_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/10\/event_140912_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/10\/event_140912_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2025\/10\/event_140912_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2025\/10\/event_140912_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2025\/10\/event_140912_original-1.jpg" }, "qr_code_url":"http:\/\/events.umich.edu\/event\/140912\/qrcode.png", "occurrence_count":1, "first_occurrence":21887799 } , { "id":"141230-21888425", "datetime_modified":"20251028T113833", "datetime_start":"20251104T120000", "datetime_end":"20251104T130000", "has_end_time":1, "date_start":"2025-11-04", "date_end":"2025-11-04", "time_start":"12:00:00", "time_end":"13:00:00", "time_zone":"America\/Detroit", "event_title":"EEB Tuesday Seminar Series - A holistic framework to assess plants, pollinators, and plant-pollinator interactions given novel herbicide exposure", "occurrence_title":"", "combined_title":"EEB Tuesday Seminar Series - A holistic framework to assess plants, pollinators, and plant-pollinator interactions given novel herbicide exposure: Veronica Iriart, EEB Postdoctoral Fellow, Baucom Lab & James Lab", "event_subtitle":"Veronica Iriart, EEB Postdoctoral Fellow, Baucom Lab & James Lab", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Description: Worldwide pollinator declines are a growing concern amid the scientific community and the public at large. While modern agricultural practices have been identified as a major factor contributing to the pollinator crisis, most of the research on this topic has focused on the effects of insecticide use on pollinators. In contrast, far less effort has been invested in trying to understand the possible downstream effects of herbicide use on pollinators via their effects on the plants upon which pollinators rely for floral resources. This oversight is especially alarming because herbicides surpass insecticides as the most highly-used class of pesticide in the world, and instances of pollution from newly-adopted herbicides, namely synthetic auxin (\u201cauxinic\u201d) herbicides, are rising. Moreover, my PhD work has shown that low dose exposures to auxinic herbicides can disrupt the growth and flowering of plant species commonly found in agroecosystems and the root mutualism between legumes and nitrogen-fixing rhizobial bacteria. Yet, the effects on plant-pollinator mutualisms in field-realistic scenarios are just beginning to be understood. In this seminar, I will present the main findings from my dissertation as well as preliminary results from my ongoing postdoctoral project, which aims to assess the effects of novel auxinic herbicide exposure on plants, pollinators, and plant-pollinator interactions. In doing so, we apply a holistic framework by investigating the impact of other relevant biotic factors present in agroecosystems (e.g. herbivores and soil microbes) that might also be important for mediating the consequences of herbicide exposure for plants and pollinators.", "occurrence_notes":null, "guid":"141230-21888425@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/141230", "building_id":"1005169", "building_name":"Biological Sciences Building", "building_official_id":1005169, "campus_maps_id":"631", "campus_maps_link_path":"biological-sciences-building", "campus_maps_link":"https:\/\/maps.studentlife.umich.edu\/building\/biological-sciences-building", "room":"1010", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["department of ecology and evolutionary biology"], "website":"", "links":[ ], "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"EEB Tuesday Lunch Seminars", "group_id":"3823", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/10\/event_141230_original-1.jpg", "image_description":"Event poster", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2025\/10\/event_141230_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2025\/10\/event_141230_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/10\/event_141230_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/10\/event_141230_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2025\/10\/event_141230_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2025\/10\/event_141230_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2025\/10\/event_141230_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2025\/10\/event_141230_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2025\/10\/event_141230_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2025\/10\/event_141230_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/10\/event_141230_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/10\/event_141230_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2025\/10\/event_141230_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2025\/10\/event_141230_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2025\/10\/event_141230_original-1.jpg" }, "qr_code_url":"http:\/\/events.umich.edu\/event\/141230\/qrcode.png", "occurrence_count":1, "first_occurrence":21888425 } , { "id":"137281-21880021", "datetime_modified":"20251030T122624", "datetime_start":"20251106T160000", "datetime_end":"20251106T170000", "has_end_time":1, "date_start":"2025-11-06", "date_end":"2025-11-06", "time_start":"16:00:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"EEB Thursday Seminar Series - Evolution in Space: Incorporating Geography into Statistical Methods for Population Genetics", "occurrence_title":"", "combined_title":"EEB Thursday Seminar Series - Evolution in Space: Incorporating Geography into Statistical Methods for Population Genetics: Gideon Bradburd, University of Michigan", "event_subtitle":"Gideon Bradburd, University of Michigan", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Seminar Summary - One of the fundamental goals of evolutionary biology is to quantify patterns of genetic diversity between populations and study the processes that shape them.

Together, these studies present a new framework on studying the community-level consequences of global change in birds and beyond.", "occurrence_notes":null, "guid":"141589-21889049@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/141589", "building_id":"1005169", "building_name":"Biological Sciences Building", "building_official_id":1005169, "campus_maps_id":"631", "campus_maps_link_path":"biological-sciences-building", "campus_maps_link":"https:\/\/maps.studentlife.umich.edu\/building\/biological-sciences-building", "room":"1010", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["department of ecology and evolutionary biology"], "website":"", "links":[ ], "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"EEB Tuesday Lunch Seminars", "group_id":"3823", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/11\/event_141589_original-1.jpg", "image_description":"Event poster", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2025\/11\/event_141589_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2025\/11\/event_141589_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/11\/event_141589_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/11\/event_141589_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb\/media\/attachments\/2025\/11\/event_141589_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb_square\/media\/attachments\/2025\/11\/event_141589_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large\/media\/attachments\/2025\/11\/event_141589_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large_lightbox\/media\/attachments\/2025\/11\/event_141589_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_crop\/media\/attachments\/2025\/11\/event_141589_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_list\/media\/attachments\/2025\/11\/event_141589_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/11\/event_141589_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/11\/event_141589_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_grid_2x\/media\/attachments\/2025\/11\/event_141589_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_large\/media\/attachments\/2025\/11\/event_141589_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_thumb\/media\/attachments\/2025\/11\/event_141589_original-1.jpg" }, "qr_code_url":"http:\/\/events.umich.edu\/event\/141589\/qrcode.png", "occurrence_count":1, "first_occurrence":21889049 } , { "id":"139063-21884712", "datetime_modified":"20250909T124836", "datetime_start":"20251112T100000", "datetime_end":"20251112T130000", "has_end_time":1, "date_start":"2025-11-12", "date_end":"2025-11-12", "time_start":"10:00:00", "time_end":"13:00:00", "time_zone":"America\/Detroit", "event_title":"Winter 2026 Backpacking", "occurrence_title":"", "combined_title":"Winter 2026 Backpacking: Program in Biology & Undergraduate Program in Neuroscience Staff", "event_subtitle":"Program in Biology & Undergraduate Program in Neuroscience Staff", "event_type":"Reception \/ Open House", "event_type_id":"17", "description":"Stop by the BSB lobby (atrium) to get help with your backpacking needs.

Ecologists have been tasked with forecasting community and ecosystem responses to these multiple concurrent drivers. My research focuses on plant community responses to multiple global change drivers, and whether these community shifts drive changes in ecosystem function. I will discuss the results of data synthesis efforts examining global patterns of plant community responses to altered resources and their consequences for primary productivity. The Community Responses to Resource Experiments (CoRRE) database includes 138 experiments from 70 locations globally and 2875 individual plant species with categorical and continuous traits.

However, many features that constitute these traits are complex, multidimensional and challenging to quantify. In this presentation, I investigate how representations of the same biological trait can influence downstream assessments of evolutionary outcomes. I use snake diets as a case study, with diet acting as a case example of an ecological trait that can be represented under different biological criteria. I will apply a similar approach to a color pattern dataset of Australian lizards (Ctenotus) in the remainder of my dissertation and will use multiple scoring and modeling approaches to test how color pattern has evolved within in this genus. Finally, I will leverage phylogenomic and microhabitat data to explore the distribution of color patterns in populations undergoing different stages of speciation and apply this knowledge to improve understanding of species boundaries between Ctenotus. In doing so, I will provide a more holistic view of how organisms and their traits evolve over time.", "occurrence_notes":null, "guid":"141767-21889332@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/141767", "building_id":"1005169", "building_name":"Biological Sciences Building", "building_official_id":1005169, "campus_maps_id":"631", "campus_maps_link_path":"biological-sciences-building", "campus_maps_link":"https:\/\/maps.studentlife.umich.edu\/building\/biological-sciences-building", "room":"1010", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["department of ecology and evolutionary biology"], "website":"", "links":[ ], "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"EEB Tuesday Lunch Seminars", "group_id":"3823", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/11\/event_141767_original-1.jpg", "image_description":"Event poster", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2025\/11\/event_141767_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2025\/11\/event_141767_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/11\/event_141767_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/11\/event_141767_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb\/media\/attachments\/2025\/11\/event_141767_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb_square\/media\/attachments\/2025\/11\/event_141767_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large\/media\/attachments\/2025\/11\/event_141767_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large_lightbox\/media\/attachments\/2025\/11\/event_141767_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_crop\/media\/attachments\/2025\/11\/event_141767_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_list\/media\/attachments\/2025\/11\/event_141767_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/11\/event_141767_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/11\/event_141767_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_grid_2x\/media\/attachments\/2025\/11\/event_141767_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_large\/media\/attachments\/2025\/11\/event_141767_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_thumb\/media\/attachments\/2025\/11\/event_141767_original-1.jpg" }, "qr_code_url":"http:\/\/events.umich.edu\/event\/141767\/qrcode.png", "occurrence_count":1, "first_occurrence":21889332 } , { "id":"137383-21880189", "datetime_modified":"20250810T100307", "datetime_start":"20251120T160000", "datetime_end":"20251120T170000", "has_end_time":1, "date_start":"2025-11-20", "date_end":"2025-11-20", "time_start":"16:00:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"EEB Thursday Seminar Series - Dealing with anthropogenic environments: why some species thrive and how we make the best of marginal habitats", "occurrence_title":"", "combined_title":"EEB Thursday Seminar Series - Dealing with anthropogenic environments: why some species thrive and how we make the best of marginal habitats: Emilie Snell-Rood, University of Minnesota", "event_subtitle":"Emilie Snell-Rood, University of Minnesota", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Seminar Summary - Why do some species thrive in novel, anthropogenic environments, and others do not?

environments, posing risks to ecosystems and human health. Environmental bacteria and fungi have shown the ability to break down plastics, influencing the transport and fate of plastic in the environment; yet few such studies mimic realistic conditions, limiting our understanding of the rates and mechanisms of these processes. While many studies have demonstrated plastics-degrading bacteria and fungi, in nature these microbes do not exist in isolation. Additionally, many studies examine the growth of microbes on plastic as their sole carbon source; however, this does not reflect environmental conditions where various carbon sources are present. Furthermore, aquatic systems are dynamic with light, temperatures, and microbial communities varying by depth, likely leading to depth-dependent microbial metabolisms and thus plastic fate. To more accurately characterize freshwater plastic degradation, our team incubated plastics at varying lake depths and maintained the resulting complex microbial biofilms in the laboratory under similar physical and nutrient conditions. We measured how microbial communities under varied conditions mobilize plastic-derived carbon (PE-C) into the environment and assimilate it into their cells using gas chromatography isotopic ratio mass spectrometry (GC-IRMS) and nano secondary ion mass spectrometry (nanoSIMS) with 99% 13C high-density polyethylene film. We found that the rates and amounts of PE-C mobilized into the environment differs between the surface photic and deep aphotic zones. Adding natural non-plastic carbon sources boosted both the mobilization of PE-C into the environment (e.g., water and atmosphere) and cellular biomass. These findings suggest that depth is a key determinant for microbial plastic degradation and that naturally occurring non-plastic carbon sources may prime microbial degraders, enhancing degradation potential in the environment. A better understanding of the microbial constraints on environmental plastic degradation is essential for modeling the fate of plastics and plastic-derived carbon, identifying favorable biodegradation conditions, and assessing potential ecosystem impacts.", "occurrence_notes":null, "guid":"142277-21890346@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/142277", "building_id":"1005169", "building_name":"Biological Sciences Building", "building_official_id":1005169, "campus_maps_id":"631", "campus_maps_link_path":"biological-sciences-building", "campus_maps_link":"https:\/\/maps.studentlife.umich.edu\/building\/biological-sciences-building", "room":"1010", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["department of ecology and evolutionary biology"], "website":"", "links":[ ], "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"EEB Tuesday Lunch Seminars", "group_id":"3823", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2025\/12\/event_142277_original-1.jpg", "image_description":"Event poster", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2025\/12\/event_142277_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2025\/12\/event_142277_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2025\/12\/event_142277_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2025\/12\/event_142277_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2025\/12\/event_142277_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2025\/12\/event_142277_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2025\/12\/event_142277_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2025\/12\/event_142277_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2025\/12\/event_142277_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2025\/12\/event_142277_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2025\/12\/event_142277_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2025\/12\/event_142277_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2025\/12\/event_142277_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2025\/12\/event_142277_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2025\/12\/event_142277_original-1.jpg" }, "qr_code_url":"http:\/\/events.umich.edu\/event\/142277\/qrcode.png", "occurrence_count":1, "first_occurrence":21890346 } , { "id":"144989-21896243", "datetime_modified":"20260203T140941", "datetime_start":"20260210T120000", "datetime_end":"20260210T130000", "has_end_time":1, "date_start":"2026-02-10", "date_end":"2026-02-10", "time_start":"12:00:00", "time_end":"13:00:00", "time_zone":"America\/Detroit", "event_title":"EEB Tuesday Seminar Series: Context-dependent collaboration and conflict in microbial mutualisms", "occurrence_title":"", "combined_title":"EEB Tuesday Seminar Series: Context-dependent collaboration and conflict in microbial mutualisms: Mackenzie Caple, Postdoctoral Fellow, Eastern Michigan University (Emily Grman's lab)", "event_subtitle":"Mackenzie Caple, Postdoctoral Fellow, Eastern Michigan University (Emily Grman's lab)", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Description: Resource context often has a large effect on the ecology and evolution of nutritional mutualisms, such as the symbiosis between leguminous plants and rhizobium bacteria.

Specifically, I will (1) assess the phylogenetic distribution of virus diversity across the Class Mammalia, relative to host species richness; (2) integrate host-virus suitability landscapes to gauge multi-annual level of risk for Choclo hantavirus and its rodent host (Oligoryzomys); and (3) test how mito-nuclear linkages shape hybrid dynamics in red-backed voles (Clethrionomys).

Science communication is considered an important part of professional development, yet the opportunities for engaging in outreach activities often favor certain venues (e.g., museums) and audiences (e.g., K-12). As a result, public reach is biased towards more mobile and\/or affluent communities with easier access to engagement opportunities, leaving many populations out of the conversation entirely. In my talk, I will share my experiences participating in and organizing outreach efforts aimed at bringing underrepresented, 'non-traditional' audiences into scientific conversations including scientist and audience testimonials as well as the logistical challenges of working in certain venues.\n----------\nSpeaker 2: Patricia Torres Pineda, PhD candidate\nMuseo Nacional de Historia Natural \"Prof. Eugenio de Jes\u00fas Marcano\", Santo Domingo, R.D\n\nTitle: The colonial legacies of natural history collections: specimens from the Caribbean as a case study\n\nDescription: It has been estimated that at least 1.1 billion zoological specimens are housed in natural history museums and collections around the world. These specimens comprise the foundation of a plethora of biological and environmental research, including studies on wildlife biology, ecology, and conservation, habitat restoration, predictive investigations related to climate change and public health, as well as education and public engagement. In the last decades, museum and collections professionals have started important conversations regarding the colonial legacies that have shaped and, in many cases, still inform the practices, access, and use (or lack thereof) of collections. Regrettably, these debates are still not as prevalent in the field of natural history collections and museums. Despite the Caribbean being one of the top Biodiversity hotspots of the planet (geographic areas that concentrate a large number of unique species), this diversity is not being fairly represented in Caribbean-based museums and collections. Here, I present preliminary results of an exploratory study on the geopolitical distribution patterns of zoological natural history specimens from the Caribbean in collections around the world, where striking disparities in quantity and quality of collections housed locally, in comparison with those in Global North institutions, become evident. In order to address the causes and implications of these biases and open a dialogue that moves us towards more inclusive and fairer practices in zoological collecting and curating, we must understand the extent and magnitude of the disparities.", "occurrence_notes":null, "guid":"145399-21897247@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/145399", "building_id":"1005169", "building_name":"Biological Sciences Building", "building_official_id":1005169, "campus_maps_id":"631", "campus_maps_link_path":"biological-sciences-building", "campus_maps_link":"https:\/\/maps.studentlife.umich.edu\/building\/biological-sciences-building", "room":"1010", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["department of ecology and evolutionary biology"], "website":"", "links":[ ], "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"EEB Tuesday Lunch Seminars", "group_id":"3823", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/02\/event_145399_original-1.jpg", "image_description":"Event poster", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_thumb\/media\/attachments\/2026\/02\/event_145399_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/02\/event_145399_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/02\/event_145399_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/02\/event_145399_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb\/media\/attachments\/2026\/02\/event_145399_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb_square\/media\/attachments\/2026\/02\/event_145399_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large\/media\/attachments\/2026\/02\/event_145399_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large_lightbox\/media\/attachments\/2026\/02\/event_145399_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_crop\/media\/attachments\/2026\/02\/event_145399_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_list\/media\/attachments\/2026\/02\/event_145399_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/02\/event_145399_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/02\/event_145399_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_grid_2x\/media\/attachments\/2026\/02\/event_145399_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_large\/media\/attachments\/2026\/02\/event_145399_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/02\/event_145399_original-1.jpg" }, "qr_code_url":"http:\/\/events.umich.edu\/event\/145399\/qrcode.png", "occurrence_count":1, "first_occurrence":21897247 } , { "id":"137386-21880192", "datetime_modified":"20260120T123657", "datetime_start":"20260219T160000", "datetime_end":"20260219T170000", "has_end_time":1, "date_start":"2026-02-19", "date_end":"2026-02-19", "time_start":"16:00:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"EEB Thursday Seminar Series - Phytochemical diversity regulates resiliency to herbivory and environmental stressors", "occurrence_title":"", "combined_title":"EEB Thursday Seminar Series - Phytochemical diversity regulates resiliency to herbivory and environmental stressors: Andrea Glassmire, Michigan State University", "event_subtitle":"Andrea Glassmire, Michigan State University", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Seminar Summary - Plants exist in a complex chemical world, producing diverse blends of metabolites that shape interactions with herbivores, microbes, and the broader ecological community. My research program integrates chemical ecology, metabolomics, and community ecology to understand how phytochemical diversity\u2014both within and among plant species\u2014governs ecological stability across natural and managed ecosystems. Using Phragmites australis in threatened U.S. wetlands and solanaceous crops such as tomato and potato in agricultural systems, my work examines how phytochemical diversity and variation mediate competition, defense, and mutualisms across multiple trophic levels.\nAcross wetlands, I investigate how native and invasive lineages of P. australis differ in chemical trait expression, how environmental stress gradients shape metabolic plasticity, and how these differences influence competitive outcomes and invasion dynamics. In agricultural systems, I test how terpene complexity alters herbivore and natural enemy behavior, revealing general principles of how insects interpret multicomponent odor cues. Together, these approaches demonstrate how chemical diversity structures ecological networks, affects biocontrol efficacy, and shapes ecosystem resilience.\nBy linking mechanistic plant chemistry with ecological processes, my research provides a trait-based framework for predicting species coexistence, improving ecosystem management, and designing sustainable, chemically informed strategies for conservation and agriculture.", "occurrence_notes":null, "guid":"137386-21880192@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/137386", "building_id":"1005169", "building_name":"Biological Sciences Building", "building_official_id":1005169, "campus_maps_id":"631", "campus_maps_link_path":"biological-sciences-building", "campus_maps_link":"https:\/\/maps.studentlife.umich.edu\/building\/biological-sciences-building", "room":"1060", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["department of ecology and evolutionary biology"], "website":"", "links":[ ], "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"EEB Thursday Seminars", "group_id":"3822", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/01\/event_137386_original-1.png", "image_description":"Event Poster", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2026\/01\/event_137386_original-1.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/01\/event_137386_original-1.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/01\/event_137386_original-1.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/01\/event_137386_original-1.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2026\/01\/event_137386_original-1.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2026\/01\/event_137386_original-1.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2026\/01\/event_137386_original-1.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2026\/01\/event_137386_original-1.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2026\/01\/event_137386_original-1.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2026\/01\/event_137386_original-1.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/01\/event_137386_original-1.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/01\/event_137386_original-1.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2026\/01\/event_137386_original-1.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2026\/01\/event_137386_original-1.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/01\/event_137386_original-1.png" }, "qr_code_url":"http:\/\/events.umich.edu\/event\/137386\/qrcode.png", "occurrence_count":1, "first_occurrence":21880192 } , { "id":"145662-21897656", "datetime_modified":"20260218T120842", "datetime_start":"20260224T120000", "datetime_end":"20260224T130000", "has_end_time":1, "date_start":"2026-02-24", "date_end":"2026-02-24", "time_start":"12:00:00", "time_end":"13:00:00", "time_zone":"America\/Detroit", "event_title":"EEB Tuesday Seminar\/ Prelim Seminar- Symbionts and Syndromes: How Has Anthropogenic Activity Influenced Bat Symbionts?", "occurrence_title":"", "combined_title":"EEB Tuesday Seminar\/ Prelim Seminar- Symbionts and Syndromes: How Has Anthropogenic Activity Influenced Bat Symbionts?: Aleana Savage, EEB PhD Student (Co-advised by Dr. Meg Duffy and Dr. Kelly Speer)", "event_subtitle":"Aleana Savage, EEB PhD Student (Co-advised by Dr. Meg Duffy and Dr. Kelly Speer)", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Description: This talk is part of my proposal defense for my dissertation, which will investigate how anthropogenic land use alters ecological and evolutionary processes of host-symbiont relationships.

Previous studies have shown that species traits, such as physical characteristics or ecological roles, often fail to explain these patterns. This dissertation explores whether emergent, population-level processes influence species formation and extinction rates, thus addressing a core question in evolutionary biology: how and why did life become so diverse? Specifically, I investigate whether sexual selection intensity (Chapter 2) and population-level persistence over decadal timescales (Chapter 3) or millennia (Chapter 4) drive diversification rates at million-year timescales. I also show how mixing different levels of organization, like species and populations, can severely bias inferences on evolutionary rates across millions of years (Chapter 5). Finally, I present an open-source tool for teaching evolutionary biology through an interactive, data-driven framework (Chapter 6). I conclude that a comprehensive understanding of Earth's biodiversity dynamics demands the integration of evidence across a wide array of disciplines.", "occurrence_notes":null, "guid":"146238-21898693@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/146238", "building_id":"1005169", "building_name":"Biological Sciences Building", "building_official_id":1005169, "campus_maps_id":"631", "campus_maps_link_path":"biological-sciences-building", "campus_maps_link":"https:\/\/maps.studentlife.umich.edu\/building\/biological-sciences-building", "room":"1010", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["department of ecology and evolutionary biology"], "website":"", "links":[ ], "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"EEB Defenses", "group_id":"3821", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "image_description":"Event poster", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2026\/03\/event_146238_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/03\/event_146238_original-1.jpg" }, "qr_code_url":"http:\/\/events.umich.edu\/event\/146238\/qrcode.png", "occurrence_count":1, "first_occurrence":21898693 } , { "id":"146429-21899078", "datetime_modified":"20260310T153550", "datetime_start":"20260317T120000", "datetime_end":"20260317T130000", "has_end_time":1, "date_start":"2026-03-17", "date_end":"2026-03-17", "time_start":"12:00:00", "time_end":"13:00:00", "time_zone":"America\/Detroit", "event_title":"EEB Tuesday Seminar Series- Within-lineage evolution across time scales: Reconciling the recent and the fossil record", "occurrence_title":"", "combined_title":"EEB Tuesday Seminar Series- Within-lineage evolution across time scales: Reconciling the recent and the fossil record: Kjetil Lysne Voje, Professor, University of Oslo", "event_subtitle":"Kjetil Lysne Voje, Professor, University of Oslo", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Description: Connecting generational processes (microevolution) to the larger-scale patterns of phenotypic diversification (macroevolution) remains a fundamental challenge in evolutionary biology. Phenotypic time series, defined as sequences of measurements drawn from multiple organisms in the same lineage over time, offer a direct window into this problem. Time series from the fossil record typically span tens to hundreds of thousands of years or more, documenting historical patterns of evolutionary change in a single species over durations far beyond what we can observe in the present. This makes fossil trait series a uniquely valuable data source for addressing fundamental questions about how evolution operates across time scales.

Ecologists have long sought to understand spatial and temporal patterns in abundance and biodiversity, but the classical approach to developing theory to explain such patterns cannot work in species-rich systems, due to the \u201ccurse of dimensionality\u201d \u2013 a tendency for the parameters needed to draw inferences about a community to grow faster than the number of observations, as species richness increases. \nIn this talk, I will summarize one strand of my lab\u2019s research program, which aims to explore potential solutions to the curse of dimensionality, test them with empirical data \u2013 mainly from coral reefs \u2013 and use them to unveil the factors that structure marine assemblages. I will begin by summarizing our earlier work developing a robust test of neutral theory of biodiversity, the most aggressively simplifying of biodiversity theories. I will then present work extending an alternative, intermediate-complexity mathematical theory that evaluates the dynamics of species\u2019 relative abundances to quantify the relative importance of deterministic and stochastic processes that generate patterns in community structure; when applied to coral reef fishes on the Great Barrier Reef, that work reveals that reef fish communities are highly niche-structured, but that this niche structure is eroded by volatility in coral cover. Finally, I will present work relaxing the simplifying assumptions of the former theory, which uses dimension-reduction approaches to allow for considerable heterogeneity among species in both interaction strengths and responses to environmental fluctuations. When applied to reef fishes on the GBR, we find a classically Gleasonian community structure, where the dynamics of relative abundance are driven by conspecific density-dependence and \u201cresponse diversity\u201d \u2013 differential responses of species\u2019 population dynamics to environmental fluctuations, but where between-species interactions have negligible impacts on community dynamics. I will conclude with some thoughts on where community ecology stands, in terms of its ability to rigorously confront theoretical models with empirical data to answer the fundamental questions that have long motivated research in this field.", "occurrence_notes":null, "guid":"144777-21895837@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/144777", "building_id":"1005169", "building_name":"Biological Sciences Building", "building_official_id":1005169, "campus_maps_id":"631", "campus_maps_link_path":"biological-sciences-building", "campus_maps_link":"https:\/\/maps.studentlife.umich.edu\/building\/biological-sciences-building", "room":"1060", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["department of ecology and evolutionary biology"], "website":"https:\/\/striresearch.si.edu\/connolly-lab\/", "links":[ { "type":"other", "url":"https:\/\/striresearch.si.edu\/connolly-lab\/", "title":null } ], "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"EEB Thursday Seminars", "group_id":"3822", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/03\/event_144777_original-1.png", "image_description":"Event Poster", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2026\/03\/event_144777_original-1.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/03\/event_144777_original-1.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/03\/event_144777_original-1.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/03\/event_144777_original-1.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb\/media\/attachments\/2026\/03\/event_144777_original-1.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb_square\/media\/attachments\/2026\/03\/event_144777_original-1.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large\/media\/attachments\/2026\/03\/event_144777_original-1.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large_lightbox\/media\/attachments\/2026\/03\/event_144777_original-1.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_crop\/media\/attachments\/2026\/03\/event_144777_original-1.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_list\/media\/attachments\/2026\/03\/event_144777_original-1.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/03\/event_144777_original-1.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/03\/event_144777_original-1.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_grid_2x\/media\/attachments\/2026\/03\/event_144777_original-1.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_large\/media\/attachments\/2026\/03\/event_144777_original-1.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_thumb\/media\/attachments\/2026\/03\/event_144777_original-1.png" }, "qr_code_url":"http:\/\/events.umich.edu\/event\/144777\/qrcode.png", "occurrence_count":1, "first_occurrence":21895837 } , { "id":"146587-21899317", "datetime_modified":"20260313T170530", "datetime_start":"20260324T120000", "datetime_end":"20260324T130000", "has_end_time":1, "date_start":"2026-03-24", "date_end":"2026-03-24", "time_start":"12:00:00", "time_end":"13:00:00", "time_zone":"America\/Detroit", "event_title":"EEB Tuesday Seminar Series- Spontaneous mutation rate and spectrum are modulated by organismal fitness", "occurrence_title":"", "combined_title":"EEB Tuesday Seminar Series- Spontaneous mutation rate and spectrum are modulated by organismal fitness: Shuting Ding, Postdoctoral Research Fellow (visiting), Department of Ecology and Evolutionary Biology, University of Michigan", "event_subtitle":"Shuting Ding, Postdoctoral Research Fellow (visiting), Department of Ecology and Evolutionary Biology, University of Michigan", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Description: Understanding the principles governing mutagenesis is important because mutations are a fundamental driver of evolution and a cause of disease. Although mutation rates and spectra depend on genotype and environment, how these factors interact is unclear. We address this question using mutation accumulation experiments in 11 budding yeast strains across three environments that produce strong genotype-by-environment interactions in fitness. Analysis of over 9,000 accumulated mutations reveals that per-generation rates of all mutation types\u2014single-nucleotide variations, small insertions and deletions, segmental duplications and deletions, and chromosome gains and losses\u2014decline with increasing organismal fitness. Notably, relative mutation rates between strains tend to invert when environmental shifts reverse their relative fitness. The mutation spectrum is also partially fitness-dependent: higher-fitness strains show a lower transition-to-transversion ratio and a stronger AT mutational bias. Thus, organismal fitness shapes not only natural selection but also the quantity and composition of mutations available to selection, with broad implications for the molecular clock, adaptive evolution, and genetic load.", "occurrence_notes":null, "guid":"146587-21899317@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/146587", "building_id":"1005169", "building_name":"Biological Sciences Building", "building_official_id":1005169, "campus_maps_id":"631", "campus_maps_link_path":"biological-sciences-building", "campus_maps_link":"https:\/\/maps.studentlife.umich.edu\/building\/biological-sciences-building", "room":"1010", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["department of ecology and evolutionary biology"], "website":"", "links":[ ], "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"EEB Tuesday Lunch Seminars", "group_id":"3823", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/03\/event_146587_original-1.jpg", "image_description":"Event poster", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2026\/03\/event_146587_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/03\/event_146587_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/03\/event_146587_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/03\/event_146587_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2026\/03\/event_146587_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2026\/03\/event_146587_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2026\/03\/event_146587_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2026\/03\/event_146587_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2026\/03\/event_146587_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2026\/03\/event_146587_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/03\/event_146587_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/03\/event_146587_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2026\/03\/event_146587_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2026\/03\/event_146587_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/03\/event_146587_original-1.jpg" }, "qr_code_url":"http:\/\/events.umich.edu\/event\/146587\/qrcode.png", "occurrence_count":1, "first_occurrence":21899317 } , { "id":"147046-21900274", "datetime_modified":"20260325T114344", "datetime_start":"20260330T140000", "datetime_end":"20260330T150000", "has_end_time":1, "date_start":"2026-03-30", "date_end":"2026-03-30", "time_start":"14:00:00", "time_end":"15:00:00", "time_zone":"America\/Detroit", "event_title":"EEB Prelim Seminar Series -

In surface waters, BP is controlled by water temperature, the concentration and chemical composition of dissolved organic carbon (DOC), nutrient availability, and lake mixing. However, certain aspects of individual controls, such as the relative importance of different DOC compositions for BP, as well as how these controls collectively influence BP at the whole-lake scale, are poorly understood. My dissertation work will evaluate how BP is controlled at the ecosystem scale by answering three interconnected questions. First, what is the relative importance of phytoplankton-derived DOC versus terrestrial-derived DOC for BP? Second, what are the interactive effects of DOC composition and temperature on BP. And third, how does weather variability, including rapid changes in temperature, affect BP in lakes? These questions will be answered by analyzing long-term BP and climate records, and by experiments on DOC composition, temperature fluctuation, and DOC-temperature interactions.", "occurrence_notes":null, "guid":"146997-21900217@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/146997", "building_id":"1005169", "building_name":"Biological Sciences Building", "building_official_id":1005169, "campus_maps_id":"631", "campus_maps_link_path":"biological-sciences-building", "campus_maps_link":"https:\/\/maps.studentlife.umich.edu\/building\/biological-sciences-building", "room":"1010", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["department of ecology and evolutionary biology"], "website":"", "links":[ ], "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/03\/event_146997_original-1.jpg", "image_description":"Event poster", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2026\/03\/event_146997_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/03\/event_146997_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/03\/event_146997_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/03\/event_146997_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2026\/03\/event_146997_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2026\/03\/event_146997_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2026\/03\/event_146997_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2026\/03\/event_146997_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2026\/03\/event_146997_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2026\/03\/event_146997_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/03\/event_146997_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/03\/event_146997_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2026\/03\/event_146997_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2026\/03\/event_146997_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/03\/event_146997_original-1.jpg" }, "qr_code_url":"http:\/\/events.umich.edu\/event\/146997\/qrcode.png", "occurrence_count":1, "first_occurrence":21900217 } , { "id":"147282-21900629", "datetime_modified":"20260331T120135", "datetime_start":"20260407T120000", "datetime_end":"20260407T130000", "has_end_time":1, "date_start":"2026-04-07", "date_end":"2026-04-07", "time_start":"12:00:00", "time_end":"13:00:00", "time_zone":"America\/Detroit", "event_title":"EEB Tuesday Seminar Series- Outreach and education in the field: lessons from the Caribbean", "occurrence_title":"", "combined_title":"EEB Tuesday Seminar Series- Outreach and education in the field: lessons from the Caribbean: Jacob Allgeier and Nepsis Garcia", "event_subtitle":"Jacob Allgeier and Nepsis Garcia", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Description: Outreach and education can have lasting impacts on communities and societies, particularly in the context of scientific research that is conducted in ecosystems that which communities directly depend on for economic means and subsistence.

The non-independence of trait values is obvious from two common observations: 1) traits function modularly within body plans to create interacting units, and 2) traits show evolutionary conservatism across closely related taxa, varying far more in size than in shape along allometric lines. However, different mechanisms generating covariance can produce the same patterns of trait distribution across species, so the relative impact of evolutionary, developmental, or genetic constraints versus adaptive evolution in phenotypic change is critical for understanding the morphological diversity we observe in the world around us. In this dissertation, I explored how the evolutionary relationships between traits have shifted across different phylogenetic scales, with a focus on limb reduction and body elongation as major body plan changes in squamate reptiles (lizards and snakes). Squamates have evolved limb-reduced, elongate body plans an estimated 26-50 independent times, making them a powerful system to test hypotheses about trait evolution. First, I investigated how the multivariate evolutionary process, as described by the evolutionary variance-covariance matrix, shifts between and within two clades of scincid lizard. I found that although the two clades had similar covariance matrices, a genus of Australian lizards (Ctenotus) had a distinct evolutionary covariance structure, indicating that these evolutionary relationships can change at relatively short timescales. Next, I tested how limb reduction influences evolutionary integration within and between the limb girdles in lizards. I found that it decreased evolutionary integration, supporting the hypothesis that reduction and loss of function results in more independent evolution of traits. I suggested that developmental integration may mediate this reduction in evolutionary integration. Finally, I collected a large dataset of vertebral counts across lizards and snakes to test the relationship between body size and vertebral number (termed pleomerism). I found that non-elongate clades had no pleomerism and although most elongate clades showed pleomerism, several elongate clades upset the predicted pattern of coupling between body size and vertebral number. This result showed that well-established patterns do not necessarily apply in all groups and that clade heterogeneity must be considered in studies of trait evolution in large groups. Taken together, my dissertation demonstrates how evolutionary relationships between traits can shift at relatively short timescales as well as between clades and how integrating both function and development is vital for understanding patterns of phenotypic evolution. \n\n Advisors: Alison Davis Rabosky and Dan Rabosky", "occurrence_notes":null, "guid":"147223-21900542@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/147223", "building_id":"1005169", "building_name":"Biological Sciences Building", "building_official_id":1005169, "campus_maps_id":"631", "campus_maps_link_path":"biological-sciences-building", "campus_maps_link":"https:\/\/maps.studentlife.umich.edu\/building\/biological-sciences-building", "room":"1010", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["department of ecology and evolutionary biology"], "website":"", "links":[ ], "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"EEB Defenses", "group_id":"3821", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/03\/event_147223_original-1.jpg", "image_description":"Event poster", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_thumb\/media\/attachments\/2026\/03\/event_147223_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/03\/event_147223_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/03\/event_147223_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/03\/event_147223_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb\/media\/attachments\/2026\/03\/event_147223_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb_square\/media\/attachments\/2026\/03\/event_147223_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large\/media\/attachments\/2026\/03\/event_147223_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large_lightbox\/media\/attachments\/2026\/03\/event_147223_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_crop\/media\/attachments\/2026\/03\/event_147223_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_list\/media\/attachments\/2026\/03\/event_147223_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/03\/event_147223_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/03\/event_147223_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_grid_2x\/media\/attachments\/2026\/03\/event_147223_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_large\/media\/attachments\/2026\/03\/event_147223_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_thumb\/media\/attachments\/2026\/03\/event_147223_original-1.jpg" }, "qr_code_url":"http:\/\/events.umich.edu\/event\/147223\/qrcode.png", "occurrence_count":1, "first_occurrence":21900542 } , { "id":"147449-21901038", "datetime_modified":"20260406T123634", "datetime_start":"20260410T120000", "datetime_end":"20260410T130000", "has_end_time":1, "date_start":"2026-04-10", "date_end":"2026-04-10", "time_start":"12:00:00", "time_end":"13:00:00", "time_zone":"America\/Detroit", "event_title":"EEB Prelim Seminar Series - Under Pressure: Evolving Heat and Drought Tolerance in Ipomoea purpurea", "occurrence_title":"", "combined_title":"EEB Prelim Seminar Series - Under Pressure: Evolving Heat and Drought Tolerance in Ipomoea purpurea: Emma Foster, PhD Student, Baucom Lab", "event_subtitle":"Emma Foster, PhD Student, Baucom Lab", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Abstract: Global change has brought higher-than-average temperatures and increased frequency of drought events over the last century.

Last, what is the genetic basis of heat and drought tolerance in I. purpurea populations?\n\nPoster Photo Credit: Susan Lusardi", "occurrence_notes":null, "guid":"147449-21901038@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/147449", "building_id":"1005169", "building_name":"Biological Sciences Building", "building_official_id":1005169, "campus_maps_id":"631", "campus_maps_link_path":"biological-sciences-building", "campus_maps_link":"https:\/\/maps.studentlife.umich.edu\/building\/biological-sciences-building", "room":"3150", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["department of ecology and evolutionary biology"], "website":"", "links":[ ], "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/04\/event_147449_original-1.jpg", "image_description":"Event poster", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_thumb\/media\/attachments\/2026\/04\/event_147449_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/04\/event_147449_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/04\/event_147449_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/04\/event_147449_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb\/media\/attachments\/2026\/04\/event_147449_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb_square\/media\/attachments\/2026\/04\/event_147449_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large\/media\/attachments\/2026\/04\/event_147449_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large_lightbox\/media\/attachments\/2026\/04\/event_147449_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_crop\/media\/attachments\/2026\/04\/event_147449_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_list\/media\/attachments\/2026\/04\/event_147449_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/04\/event_147449_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/04\/event_147449_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_grid_2x\/media\/attachments\/2026\/04\/event_147449_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_large\/media\/attachments\/2026\/04\/event_147449_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_thumb\/media\/attachments\/2026\/04\/event_147449_original-1.jpg" }, "qr_code_url":"http:\/\/events.umich.edu\/event\/147449\/qrcode.png", "occurrence_count":1, "first_occurrence":21901038 } , { "id":"147440-21901029", "datetime_modified":"20260406T121749", "datetime_start":"20260410T160000", "datetime_end":"20260410T170000", "has_end_time":1, "date_start":"2026-04-10", "date_end":"2026-04-10", "time_start":"16:00:00", "time_end":"17:00:00", "time_zone":"America\/Detroit", "event_title":"EEB Prelim Seminar Series - Stress and the anthropocene: investigating changing facilitative and competitive interactions in novel ecosystems", "occurrence_title":"", "combined_title":"EEB Prelim Seminar Series - Stress and the anthropocene: investigating changing facilitative and competitive interactions in novel ecosystems: Hanna Petroski, PhD student, Howard Lab", "event_subtitle":"Hanna Petroski, PhD student, Howard Lab", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Summary: Human activity has changed the stressors natural systems are subjected to, producing novel ecoystems.

It is a central component of parasite fitness and forms one part of a widely studied trade-off in evolutionary biology; the virulence-transmission tradeoff. The evolution of virulence has been studied extensively over the last 4 decades but any changes in virulence are largely investigated either in theory or simple empirical experiments that focus on one-to-one host-parasite relationships. In chapter 1 of my dissertation work, I will use phage-bacteria model systems to empirically investigate how parasite virulence evolves in assemblages with multiple hosts and parasites. In addition to being tractable models for host-parasite coevolution, bacteria-phage communities can be used as a kind of living epidemiological model. In chapter 2, I will use phage pathogens with starkly different life cycles (chronic and temperate) to conduct experimental tests of evolutionary-epidemiological theory and question if pathogen virulence in \u201ctwindemic\u201d scenarios adapts to the predicted epidemiological optima. Finally, when multiple infections are common, pathogens exhibit unique life-cycle strategies that may prioritize virulence or prudence. Recent discoveries of phage signaling systems raise questions about how switching between virulent and prudent life cycles occurs molecularly, and the role phage-to-phage communication plays. In the final chapter, I will investigate phage communication\u2019s role in modulating virulence.", "occurrence_notes":null, "guid":"147509-21901156@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/147509", "building_id":"1005169", "building_name":"Biological Sciences Building", "building_official_id":1005169, "campus_maps_id":"631", "campus_maps_link_path":"biological-sciences-building", "campus_maps_link":"https:\/\/maps.studentlife.umich.edu\/building\/biological-sciences-building", "room":"1010", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["department of ecology and evolutionary biology"], "website":"", "links":[ ], "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"EEB Tuesday Lunch Seminars", "group_id":"3823", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/04\/event_147509_original-1.jpg", "image_description":"Event poster", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_thumb\/media\/attachments\/2026\/04\/event_147509_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/04\/event_147509_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/04\/event_147509_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/04\/event_147509_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb\/media\/attachments\/2026\/04\/event_147509_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb_square\/media\/attachments\/2026\/04\/event_147509_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large\/media\/attachments\/2026\/04\/event_147509_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large_lightbox\/media\/attachments\/2026\/04\/event_147509_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_crop\/media\/attachments\/2026\/04\/event_147509_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_list\/media\/attachments\/2026\/04\/event_147509_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/04\/event_147509_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/04\/event_147509_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_grid_2x\/media\/attachments\/2026\/04\/event_147509_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_large\/media\/attachments\/2026\/04\/event_147509_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_thumb\/media\/attachments\/2026\/04\/event_147509_original-1.jpg" }, "qr_code_url":"http:\/\/events.umich.edu\/event\/147509\/qrcode.png", "occurrence_count":1, "first_occurrence":21901156 } , { "id":"147536-21901211", "datetime_modified":"20260408T130350", "datetime_start":"20260414T150000", "datetime_end":"20260414T160000", "has_end_time":1, "date_start":"2026-04-14", "date_end":"2026-04-14", "time_start":"15:00:00", "time_end":"16:00:00", "time_zone":"America\/Detroit", "event_title":"EEB Prelim Seminar Series - Evolution of gene expression noise", "occurrence_title":"", "combined_title":"EEB Prelim Seminar Series - Evolution of gene expression noise: Zhizhou Jia, EEB PhD student, Zhang lab", "event_subtitle":"Zhizhou Jia, EEB PhD student, Zhang lab", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Description: Gene expression noise, the variation in gene expression levels among isogenic cells in a shared environment, has been characterized over the past two decades.

Here, we examine whether stress associated with reduced atmospheric moisture impacts plant investment in mite domatia, small structures on leaves that mediate a mutualism between plants and defensive mites using riverbank grape (Vitis riparia). We tested prediction of the stress gradient hypothesis at two scales: a local scale using a humidity gradient created by distance from an island lake, and a region scale spanning a precipitation gradient across Michigan\u2019s lower peninsula. At each scale, we measured domatia size, density, and abundance, as well as mite abundance and leaf fungal hyphal load. At the local scale, domatia trichome density was significantly higher in less humid environments, consistent with the stress gradient hypothesis, and mite abundance increased with both humidity and domatia density. At the regional scale, mite abundance increased significantly with precipitation, but no relationship was detected between precipitation and any measure of domatia investment or fungal load. Together, these results suggest that the stress gradient hypothesis partially applies to the plant\u2013mite mutualism in this system, but that its expression depends on scale and the range of moisture conditions experienced.", "occurrence_notes":null, "guid":"147742-21901778@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/147742", "building_id":"1000189", "building_name":"Dana Natural Resources Building", "building_official_id":1000189, "campus_maps_id":"45", "campus_maps_link_path":"dana-samuel-trask-building", "campus_maps_link":"https:\/\/maps.studentlife.umich.edu\/building\/dana-samuel-trask-building", "room":"1024", "location_name":"Dana Natural Resources Building", "has_livestream":0, "cost":"", "tags":["department of ecology and evolutionary biology"], "website":"", "links":[ ], "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"EEB Defenses", "group_id":"3821", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/04\/event_147742_original-1.jpg", "image_description":"Event poster", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2026\/04\/event_147742_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/04\/event_147742_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/04\/event_147742_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/04\/event_147742_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2026\/04\/event_147742_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2026\/04\/event_147742_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2026\/04\/event_147742_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2026\/04\/event_147742_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2026\/04\/event_147742_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2026\/04\/event_147742_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/04\/event_147742_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/04\/event_147742_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2026\/04\/event_147742_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2026\/04\/event_147742_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/04\/event_147742_original-1.jpg" }, "qr_code_url":"http:\/\/events.umich.edu\/event\/147742\/qrcode.png", "occurrence_count":1, "first_occurrence":21901778 } , { "id":"147768-21901948", "datetime_modified":"20260415T125520", "datetime_start":"20260423T130000", "datetime_end":"20260423T140000", "has_end_time":1, "date_start":"2026-04-23", "date_end":"2026-04-23", "time_start":"13:00:00", "time_end":"14:00:00", "time_zone":"America\/Detroit", "event_title":"EEB Thesis Defense: Survey of the Natural History of Hesperis matronalis and the abiotic and biotic drivers of its Viruses", "occurrence_title":"", "combined_title":"EEB Thesis Defense: Survey of the Natural History of Hesperis matronalis and the abiotic and biotic drivers of its Viruses: Susan Lusardi", "event_subtitle":"Susan Lusardi", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Summary: In a phenotypic and bioinformatic survey of the natural history of Hesperis matronalis across southern Michigan I found that both land cover type and longitude are positively correlated with infection of TuMV at the phenotypic level.

For example, identifying environmental variables that influence gene flow can help us predict how populations may respond to rapidly shifting ecologies in the face of climate change. However, when nearby environments tend to be similar, it is hard to tell whether observed patterns of gene flow are actually controlled by environmental variables, or whether they are just controlled by distance, which is the default expectation. In this talk, I will introduce an update that I developed to the R package BEDASSLE, which is designed to distinguish between these scenarios, called isolation by environment (IBE) and isolation by distance (IBD). My update modifies the underlying model, making the package faster and compatible with larger datasets, and adds a model selection component that directly tests whether IBE, IBD, or both combined, best explains the data. The updated method performed well on my simulated data, suggesting that it could be a useful tool for understanding what shapes genetic structure in populations.\n\nAdvisor: Gideon Bradburd", "occurrence_notes":null, "guid":"148151-21903160@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/148151", "building_id":"1005169", "building_name":"Biological Sciences Building", "building_official_id":1005169, "campus_maps_id":"631", "campus_maps_link_path":"biological-sciences-building", "campus_maps_link":"https:\/\/maps.studentlife.umich.edu\/building\/biological-sciences-building", "room":"1010", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["department of ecology and evolutionary biology"], "website":"", "links":[ ], "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"EEB Defenses", "group_id":"3821", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "image_description":"Event poster", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb_square\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large_lightbox\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_crop\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_list\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_grid_2x\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_large\/media\/attachments\/2026\/05\/event_148151_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_thumb\/media\/attachments\/2026\/05\/event_148151_original-1.jpg" }, "qr_code_url":"http:\/\/events.umich.edu\/event\/148151\/qrcode.png", "occurrence_count":1, "first_occurrence":21903160 } , { "id":"148235-21903427", "datetime_modified":"20260512T113906", "datetime_start":"20260515T100000", "datetime_end":"20260515T110000", "has_end_time":1, "date_start":"2026-05-15", "date_end":"2026-05-15", "time_start":"10:00:00", "time_end":"11:00:00", "time_zone":"America\/Detroit", "event_title":"EEB Student Thesis Defense - Comparing Phyllostomid Bat Brains to Feeding Strategies", "occurrence_title":"", "combined_title":"EEB Student Thesis Defense - Comparing Phyllostomid Bat Brains to Feeding Strategies: Samantha Henry", "event_subtitle":"Samantha Henry", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Summary: In mammals, large brains are associated with improved cognitive performance and complex social interactions. Some hypotheses posit that solving complex ecological problems (e.g., foraging) drive some taxa to evolve large brains. Although many studies have analyzed bat brain size relative to diet, few have analyzed bat brain shape in the same way. The bat family Phyllostomidae is an ideal taxonomic group to examine brain morphology and diet because of the wide range of diet types within the family, including carnivores, frugivores, insectivores, nectarivores, omnivores, and sanguivores. My thesis addressed two questions: (1) what is the effect of various diets on brain size in phyllostomid bats; and (2) what is the effect of various diets on the shape of the brain in phyllostomid bats? Using 3D Slicer (3D segmentation and visualization software), I generated endocranial casts (endocasts) from the skulls of 73 voucher specimens located in four natural history museums. Endocasts are often used as a proxy for brain size and shape. I used 3D Slicer to determine the endocast volume, measure the occipital condyle width (a proxy for body size), place 30 fixed landmarks on the endocast, and export Procrustes landmark coordinates to determine size and shape. The results indicated that diet was not a significant predictor of endocast volume in phylogenetic analysis of variance (ANOVA) models. However, the generalized linear mixed models showed that frugivorous and sanguivorous phyllostomids had significantly larger endocast volumes than insectivorous phyllostomids, but the magnitude of the change was not large. Regarding endocast shape, the principal component analysis (PCA) showed that the first principal component accounts for 18.9% of the variation in brain shape, which corresponds with some aspects of cerebrum and cerebellum size along the sagittal plane, and length of the olfactory bulb. The second principal component accounts for 14.3% of the variation in brain shape, which corresponds with changes in endocast height and width. The third principal component accounts for 10.6% of the variation in brain shape, which corresponds to the width of the olfactory bulb and the paraflocculus. Based on the PCA and the phylogenetic Procrustes ANOVA results, the effects of diet on endocast shape in phyllostomid bats appear minimal or absent.

Fall migration requires the coordinated expression of seasonally plastic traits such as oriented flight behavior and reproductive diapause (delayed reproduction during migration). The amalgamation of these component traits is dubbed the migratory syndrome. Yet, how these component phenotypes are integrated to form the migratory syndrome remains a largely open question. In my dissertation I studied how environmental and developmental factors interact to influence phenotypic plasticity of component migratory traits by combining field experiments with multi-omics (genomic, transcriptomic, and epigenomic) techniques. In Chapter 2 I uncover that reproductive diapause imparts a lasting transcriptional state which I hypothesize assists in the robustness of monarch butterflies during their return migration. In Chapter 3 I demonstrate that reproductive diapause and oriented flight are distinctly induced throughout the season, and each is regulated by tissue-specific transcriptional modules. Further, I also find that the unique oriented flight behavior during the seasonal transition from summer to fall is controlled by substantial cryptic genetic variation, which I hypothesize helps maintain behavioral diversity amidst seasonal unpredictability. Lastly, in Chapter 4 I present research which combines RNA- and ATAC-seq data to suggest that seasonal transcriptional plasticity is controlled by unique sets of seasonally regulated transcription factors. Overall, these works demonstrate the importance of environmental variation in defining the genetic architecture of the migratory syndrome and the regulatory mechanisms that control seasonal transcriptional plasticity. Defining these mechanisms helps us understand the evolution of migration as they define the substrates by which natural selection can operate.", "occurrence_notes":null, "guid":"148237-21903428@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/148237", "building_id":"1005169", "building_name":"Biological Sciences Building", "building_official_id":1005169, "campus_maps_id":"631", "campus_maps_link_path":"biological-sciences-building", "campus_maps_link":"https:\/\/maps.studentlife.umich.edu\/building\/biological-sciences-building", "room":"1010", "location_name":"Biological Sciences Building", "has_livestream":0, "cost":"", "tags":["department of ecology and evolutionary biology"], "website":"", "links":[ ], "sponsors":[ { "group_name":"Ecology and Evolutionary Biology", "group_id":"1190", "website":"" }, { "group_name":"EEB Defenses", "group_id":"3821", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/05\/event_148237_original-1.jpg", "image_description":"Event Poster", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_thumb\/media\/attachments\/2026\/05\/event_148237_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/05\/event_148237_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/05\/event_148237_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/05\/event_148237_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb\/media\/attachments\/2026\/05\/event_148237_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb_square\/media\/attachments\/2026\/05\/event_148237_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large\/media\/attachments\/2026\/05\/event_148237_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large_lightbox\/media\/attachments\/2026\/05\/event_148237_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_crop\/media\/attachments\/2026\/05\/event_148237_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_list\/media\/attachments\/2026\/05\/event_148237_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/05\/event_148237_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/05\/event_148237_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_grid_2x\/media\/attachments\/2026\/05\/event_148237_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_large\/media\/attachments\/2026\/05\/event_148237_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_thumb\/media\/attachments\/2026\/05\/event_148237_original-1.jpg" }, "qr_code_url":"http:\/\/events.umich.edu\/event\/148237\/qrcode.png", "occurrence_count":1, "first_occurrence":21903428 } ]
