EEB Tuesday Lunch Seminar: Studying speciation in terrestrial gastropods: integrating genomic, ecological, and morphological data (September 3, 2019 12:00pm) https://events.umich.edu/event/65222 65222-16555450@events.umich.edu Event Begins: Tuesday, September 3, 2019 12:00pm

Speciation is of fundamental interest to evolutionary biologists, and is driven by a complex interplay of factors. By integrating genomic, ecological, and morphological data, we can begin to disentangle the process of speciation. The Pacific Northwest of North America has a rich history of phylogeographic research, and temperate rainforest endemics from the region have been influenced by a diverse array of factors, including climatic and geologic events. By studying groups from this region in a comparative context, we identify ecological and morphological traits influencing species responses to these events. Further, by studying speciation and species limits in an integrative context, we can begin to understand how these and other factors have contributed to speciation. We focus on terrestrial taildropper slugs (Genus Prophysaon), and infer a history of divergence followed by secondary contact, with ecological data suggesting that reinforcement may have driven speciation. By integrating across datatypes and considering the processes that drive speciation, we infer biologically meaningful species limits and learn about which factors led to speciation.

Males in many species must convince females to mate by producing elaborate courtship displays tuned to female preferences, like the song of a cricket or the train of a peacock. But courtship in many species is more like a negotiation than an advertisement, thus in addition to elaborate signals, success in courtship may require tactical skills. These skills may include the ability to choose a flattering display site, respond appropriately to female courtship signals, and adjust display investment in response to the marketplace of other males and females. My lab has been investigating courtship negotiations in greater sage-grouse, which mate in an open marketplace of competing males and choosing females (the lek). I will discuss experiments using robotic females to investigate courtship interactions between the sexes. I will also discuss ongoing research investigating how off-lek foraging behaviors affect on-lek displays, and how this basic science has informed my lab's research into human impacts on lekking activities.

The Carolina Parakeet, the Heath Hen, the Passenger Pigeon—when we contemplate how bird diversity has changed, we often focus on the handful of species we have lost entirely. But while we have yet to lose a single bird species to our rapidly changing climate, birds and other creatures are currently adapting and responding. Studying changing bird communities over decades to centuries, Dr. Tingley’s work demonstrates the complex ways that species are responding to climate change, often by shifting in space and traveling in time.

The deep ocean is frequently assumed to be a homogeneous system lacking the same diverse natural history found in shallower waters. However, as our methods for exploring the deep ocean improve, common assumptions about dispersal, reproduction and behavior are constantly being challenged. With the immense amount of data collected and stored in natural history collections to highlight historical distributions of fishes we can now use these data in concert with modern sampling methods like remote operated vehicles (ROVs) and precision netting to learn more about one of the planets most extreme systems. Join Randy as he takes you on a journey from the highest shelves of museum collections to the extreme depths of the ocean in a quest to learn more about fishes, and where to find them.

There is a broadly recognized ambiguity in the relationship between mammalian (eutherian) pregnancy and inflammation. During implantation, inflammatory pathways are activated and important for successful implantation, but during the second trimester, intrauterine inflammation is a grave threat to the continuation of pregnancy. An investigation of the gene expression changes during opossum pregnancy led us to propose and test a model for the origin of eutherian implantation and pregnancy. In brief: if we take the opossum gestation as a model of the situation at the most recent common ancestor of marsupials and placental mammals, the evidence suggests that an acute inflammation is the result of the attachment of the trophoblast to the uterine epithelium. The difference between opossum and the eutherians is the outcome: In opossum the inflammation directly leads to parturition, while in eutherians inflammation never leads to neutrophil infiltration and soon is turned off. I will present evidence suggesting that one key innovation to achieve sustainable implantation was the origin of the decidual cell, which prevents the recruitment of neutrophils and thus prevents the development of an acute inflammation during implantation.

Abstract
The riverweed family (Podostemaceae) is the largest strictly aquatic family of flowering plants and provides important habitats and food sources for many fishes and aquatic invertebrates. Highly unusual for flowering plants, species grow directly attached to rocks in river-rapids and waterfalls. Podostemaceae species exhibit high phenotypic plasticity and have highly modified growth forms, both of which contribute to taxonomic confusion. Many of the estimated 300 riverweed species are narrowly distributed and incompletely known, and evolutionary relationships within the family are uncertain. Unfortunately, many species are of conservation concern and risk extinction due to the expansion of hydroelectric dams and massive reservoirs. This talk will detail the progress on a collaborative project to better understand the phylogeny, biogeography, and systematics of Podostemaceae. In particular, we aim to better understand the biogeographical history of neotropical riverine organisms and the role that major river capture events during the Cenozoic have played in their distribution. The project includes significant fieldwork, monographic work, and an investigation of the structural organization of the family’s plastid genome. Finally, we are also developing a new online resource designed to broadly disseminate information on the family as well as a new tool for the systematics community to more easily manage monographic data for publication.

The continuing and rapid global decline of coral reefs calls for new approaches to sustain reefs and the millions of people who depend on them. In this talk, I present ongoing work by my research group aimed at rethinking reef conservation along two lines. First is directly confronting the drivers of change. In addition to environmental factors, there are socioeconomic drivers that influence the condition of coral reef ecosystems, though reef governance rarely focus on explicitly managing these. My colleagues and I analyzed data from >1800 tropical reef sites worldwide to quantify how key socioeconomic and environmental drivers are related to reef fish biomass, a key indicator of ecosystem condition and resource availability. Our global analysis reveals that the strongest driver of reef fish biomass is our metric of potential interactions with urban centres (market gravity), with important, but smaller, roles of local management, human demographics, socioeconomic development, and environmental conditions. These results highlight multiple underutilized policy levers that could help to sustain coral reefs, such as dampening the negative impact of markets. Second, drawing on theory and practice in human health and rural development, we use a positive deviance (bright spots) analysis to systematically identify coral reefs that have substantially higher biomass than expected, given their socioeconomic and environmental conditions. Importantly, bright spots were not simply comprised of remote areas with low fishing pressure- they include localities where human populations and use of ecosystems resources is high, potentially providing novel insights into how communities have successfully confronted strong drivers of change. Uncovering the mechanisms that underpin the ability of bright spots to confront high pressures may form a basis for novel policy approaches.

Abstract
Fuel reduction treatments are often designed to achieve multiple resource management objectives in addition to reducing potential fire hazard. Many studies have documented reduced fire severity for a standard set of fuel treatments, but the range of variability in fuel treatment effectiveness for alternative treatment designs is poorly understood. We used nonlinear mixed-effects modeling to estimate the distance into the treated area at which fire severity decreases and randomization tests to compare forest structure. The range of variability in observed-distance high-severity fire effects persist into the treated area and, in conjunction with estimated relationships between posttreatment forest structure and severity, can inform the design of alternative fuel treatment prescriptions with various target prescriptions. Our study will inform decision makers on the size of treatments required to accomplish management objectives.

Abstract
Populations often encounter environmental changes that remove selection for the maintenance of certain phenotypic traits. The resulting decay of these traits under relaxed selection reduces an organism’s fitness in its prior environment. However, how these traits subsequently evolve upon restoration of selection is not well-understood. We addressed this question using Escherichia coli strains from the long-term evolution experiment (LTEE) that have been independently evolving for multiple decades in the absence of antibiotics. We confirmed that these derived strains have typically become more sensitive to various antibiotics during this time. We then asked how readily the bacteria could overcome these losses of intrinsic resistance through subsequent evolution when challenged with these same drugs. In our study, we focused on the role that genetic background plays in this process, with attention to the tension between evolutionary repeatability and contingency. We found that idiosyncratic responses in evolvability dominated over trends of diminishing returns, such that the potential to evolve increased resistance was hampered on some derived genetic backgrounds. We further subjected a time-series of clones from one LTEE population to tetracycline and showed that evolutionary constraint occurred early in its history. Taken together, our results indicate that the evolution and diversification of a single species in an antibiotic-free environment can render resistance evolution unpredictable, even for closely related strains. Current work is now centered on characterizing the genomic changes underlying resistance to address whether the same genes are the focus of selection when strains have evolved for decades in the absence of antibiotics.

Land management has been proposed as a means to help lower greenhouse gas emissions and reduce atmospheric carbon dioxide (CO2) concentrations. Research in California has shown significant potential to lower methane emissions from waste management and subsequently increase short-term soil carbon (C) storage via amendments of composted organic material. However, effective climate change mitigation will require long-term or sustained emissions reduction and C sequestration. We used field experiments and modeling to explore the long-term potential of improved agricultural practices on greenhouse gas emissions and ecosystem C cycling. A decade following a one-time application of composted organic matter to grassland soils, amended plots accumulated approximately 9 Mg C ha-1 more soil C in the top 30 cm than paired controls. Aboveground plant growth was also higher in the amended plots after 10 years. Soil C stocks and C sequestration rates in compost-amended plots were resistant to rainfall and temperature changes predicted by Earth Systems Models (ESMs). We used two climate models (HadGEM and CanESM) and two climate change scenarios (RCP 4.5 and RCP 8.5) to determine the sensitivity of rangeland C dynamics to climate change with and without composted amendments to the year 2100. Drier sites yielded surprisingly high rates of C storage and were less sensitive to climate change than wetter sites. We also used a new micrometeorological approach to estimate greenhouse gas fluxes from composted manure, green waste, and food waste, the highest emitting organic waste streams. We found that manure and green waste had considerably lower methane emission factors than food waste, and that all composted wastes had lower emission factors with composting than with landfilling or slurrying. Our results show that there are alternative management approaches can both lower greenhouse gas emissions and sequester atmospheric CO2 over short and long time periods, and thus provide viable climate change mitigation approaches.

Recent changes in ecosystem properties highlight major uncertainties about how disturbances will interact with ongoing climate change. Shifting fire regimes may lead to long-lasting directional changes or shifts in biogeochemical states, potentially impacting carbon and nitrogen balance over large spatial and temporal scales. However, data have been lacking to test these ideas over longer timescales – and to consider their implications for future projections – until only recently. A network of paleoecological records will document the role of climate in past fire-regime variability, and the potential for changing biogeochemical impacts will be evaluated. Combined with inferences from ecosystem and Earth system models, these results characterize how disturbances shape biogeochemical dynamics across a range of spatial and temporal scales. The important role of biological stations in catalyzing cutting-edge research, education, and outreach will also be explored.

How distinct species persist in the face of gene flow is a long-standing and central question in evolutionary biology, reinvigorated by the recent realization that hybridization is surprisingly common. Though it is now appreciated that gene flow often occurs before, during, and after speciation, little about the evolutionary impact of hybridization is understood, from the ecological and behavioral forces driving hybridization to the ways in which selection acts on hybrid genomes. Our research addresses these questions using replicate, recently formed hybrid populations of swordtail fish. I will discuss work mapping the locations of hybrid incompatibilities and investigating the role of selection on these regions in hybrid genome evolution. I will also discuss our work investigating how selection on incompatibilities interacts with other genetic processes such as recombination. Together, this work highlights a set of mechanisms that shape hybridization on a population and genetic level.

Field stations provide platforms for transformative long-term and placed-based research as well as extraordinary opportunities for education and outreach. Dr. Classen will discuss her field station vision using some examples from her own work exploring ecosystem and global change ecology. Broadly, the Classen group explores how ecosystems function and how biotic and abiotic interactions influence patterns and processes within and among communities and ecosystems. Working across scales from the micro (soil food webs) to the macro (regional carbon fluxes) as well as across diverse terrestrial ecosystems (forests, meadows, bogs; tropics, arctic, temperate) the Classen lab uses a combination of observations, experiments, and models to answer ecological and global change questions

Please join us for our weekly brown bag lunch seminar.

In this talk, I'll summarize our work aimed at understanding the factors that shape biodiversity, from m2 quadrats to the globe. In particular, I will highlight how our work blends macroecological approaches, physiological experiments in the lab, and experimental manipulations in the field, mostly on ants. My view is that this synthetic approach, across scales, is the best way to understand and predict how biodiversity responds to global change drivers. Field stations are perfect launching pads for this kind of research and for introducing students, across disparate disciplines, to biodiversity and the services and functions it provides. Field stations can also be hubs for interdisciplinary collaborations and provide opportunities to ask, and address, pressing and fundamental questions across fields. The UMBS has been both a launching pad and hub for decades and is poised for continued growth and success.

Current extinction rates are comparable to five prior mass extinctions in the earth’s history, and are strongly affected by human activities that have modified more than half of the earth’s terrestrial surface. Increasing human activity restricts animal movements and isolates formerly connected populations, a particular concern for the conservation of large carnivores, but no prior research has used high throughput sequencing in a standardized manner to examine genetic connectivity for multiple species of large carnivores and multiple ecosystems. We used RAD SNP genotypes to test for differences in connectivity between multiple ecosystems for African wild dogs (Lycaon pictus) and lions (Panthera leo), and to test correlations between genetic distance, geographic distance and landscape resistance due to human activity. We found weaker connectivity and a stronger correlation between genetic distance and landscape resistance for lions, and propose a new hypothesis that adaptations to interspecific competition may help to explain differences in vulnerability to isolation by humans.

EEB Seminar Series: Insights into the ecology and evolution of amphibian susceptibility to chytridiomycosis in a changing world AND a vision for the U of M Biological Station (November 8, 2019 12:00pm) https://events.umich.edu/event/68572 68572-17103239@events.umich.edu Event Begins: Friday, November 8, 2019 12:00pm

The amphibian chytrid fungus, Batrachochytrium dendrobatidis (Bd) is one of several emerging pathogens identified as key threats to wildlife. In some areas of the world the introduction of Bd to naïve host communities resulted in epidemics of the disease chytridiomycosis that caused numerous declines and extinctions. Our work in western Panama, which experienced die-offs in the mid-2000s, has focused on understanding what comes after such epidemics, testing hypotheses about the roles of host and pathogen evolution in the shift to endemic dynamics, or the persistence of host and pathogen in a shared environment. Another focus of my lab’s efforts has been on clarifying how both current (i.e., seasonal) and predicted future changes in climate shape the risk of disease related declines in North American frogs. Using a combination of field studies and experiments, we have begun to clarify the effect of temperature on host immune defenses and susceptibility to chytridiomycosis, and how the opportunity for thermally-mediated host defense varies in space and time. Using mesocosm studies, we are also investigating how climate-induced stress experienced during larval development impacts later life traits, like immune defense and thermal tolerance, that affect fitness in a broader context.
The University of Michigan Biological Station (UMBS) is a tremendous resource, with strengths in research, education and community engagement. Drawing on my experience as a field station researcher and director, I’ll conclude my seminar by outlining my vision for the future of the UMBS. Here I’ll highlight ways we can build upon the station’s existing strengths to promote more collaborative and interdisciplinary research, demonstrate excellence in place-based teaching and learning, and strengthen interactions between field station users and both the U of M and Northern Michigan communities.

During speciation, sex chromosomes accumulate interspecific genetic incompatibilities faster than the rest of the genome. As a consequence, X-linked hybrid sterility is often an early stage in the evolution of reproductive isolation. To understand why the X chromosome is a hotspot for the accumulation of hybrid sterility, we have undertaken genetic and population genomic analysis of X-linked hybrid male sterility between two fruit fly sister species, Drosophila mauritiana and D. simulans. We have identified multiple X-linked regions that are sufficient to cause male sterility when introgressed from D. mauritiana into a D. simulans genome. Spermatogenesis in sterile genotypes proceeds through meiosis but does not complete spermatid individualization. Most X-linked sterility results from incompatibly interactions with autosomal alleles, but both genetic and cytological results indicate that one factor causes sterility through interactions with the heterospecific Y chromosome. Previous theory suggests that X-linked sterilizing incompatibilities may arise through the evolution of sex chromosome meiotic drive elements. We find evidence that both supports and rejects this theory, as a known X-linked drive element recently migrated between these species and caused a strong reduction in local sequence divergence. Gene flow can therefore mediate the effects of selfish genetic elements during speciation.

Abstract
This Tuesday lunch seminar will cover results from multiple biology education research projects conducted at the University of Michigan. To better understand how the background of a Graduate Student Instructor (GSI) impacts student outcomes, we surveyed both GSIs and their undergraduate students in Introduction to Biology Lab. To assess the undergraduate Ecology, Evolution, and Biodiversity (EEB) major, we surveyed 42 seniors and found a discrepancy between general climate and inclusive practices. The seminar will conclude with suggested low-cost and meaningful changes we can make to improve inclusion in our EEB classes.

The importance of biodiversity to ecosystem functions such as biomass production and carbon storage is a key question in basic ecology, where it has been investigated largely through small-scale experiments and theory. It is also a key assumption in the conservation world that maintaining ecosystem services requires maintaining biodiversity. The role of biodiversity in ecosystem service provision in real-world landscapes is far from clear scientifically, however, in part because new conceptual approaches are required to even frame the question at these larger scales. In this talk I will discuss how my research program is tackling this problem.

Abstract
Hymenoptera (bees, wasps, and ants) are some of the most numerous and diverse animals on the planet. The group includes pollinators, predators, parasitoids, herbivores and practically everything in-between. They can be found in almost every terrestrial habitat around the world (as well as a few aquatic ones) and many are essential in keeping food on our tables and pest populations under control, while others are pests themselves or are species of medical concern. Despite this insect group’s importance, and how integral it is in shaping the world we see today, there are still many fundamental unanswered questions about the taxa in this amazing group. This seminar will focus on Hymenoptera biodiversity and what the E. M. Tucker lab at the U-M Museum of Zoology is doing to explore unanswered questions about these extraordinary creatures.

The climate of the earth is becoming hotter and less predictable, and the fitness of organisms is increasingly linked to traits important for performance in a changing climate. Understanding the relative roles of phenotypic plasticity and evolutionary adaptation as responses to climate change is crucial, as phenotypic plasticity is more rapid than evolutionary adaptation, and can either facilitate or constrain evolutionary adaptation. Crucially, for certain taxa like tropical forest lizards, previous long-term climate stability of the tropics may have eroded both genetic variation and capacity for phenotypic plasticity necessary for survival under rapid environmental change. We are testing how denizens of tropical forests can respond to climate change by 1) studying physiological and phenotypic plasticity of a thermoconforming forest lizard, and 2) transplanting these lizards onto islands in the Panama Canal. These islands are hotter and more variable than the mainland rainforests of the source populations. On experimental islands, we are measuring selection (viability and fecundity) on thermal physiological traits, measuring plasticity and gene expression in response to thermal change, and identifying genomic regions that are important for thermal adaptation. Ultimately, our research can help parse the relative roles of phenotypic plasticity, genomic adaptation, and their interaction during the biological response to climate change.

Abstract
The senses are our interface with our surrounding world and attuned to specific qualities of prominent signals within the environment. Studying the ways in which senses have changed during evolution can be a marker of how organisms respond to major ecological shifts. Snakes have invaded aquatic habitats multiple times, but, with over 60 fully-aquatic and ecologically diverse species, few groups have been so successful as sea snakes (Elapidae: Hydrophiinae). I will explore the sensory evolution of sea snakes, with emphasis on two senses that are mediated by the skin: mechanoreception (touch) and tail phototaxis (skin photoreception). Tiny mechanoreceptors on the scales of sea snakes have undergone substantial changes during evolution, I will discuss whether these morphological changes are likely to confer a 'hydrodynamic' function (analogous to the lateral line system of fishes) in sea snakes. Light sensitivity of the paddle-tail in sea snakes (tail phototaxis) is a rare trait among vertebrates and convergent with other elongate, aquatic species (hagfish, lamprey, aquatic salamanders). I explore the evolutionary origins, genetic mechanisms and ecological factors underlying this fascinating sense in sea snakes.

ABSTRACT
Ecological communities are very complex systems comprising species that interact with each other in spatially extensive settings. Understanding the rules that govern these systems and how they behave in time is fundamental, but it is also of practical importance since it concerns the maintenance of biodiversity in the face of global change. In this talk I combine results from experiments in manipulable communities of small animals and microorganisms with math modeling, and large scale analyses of functional trait information to advance our understanding of the organizational principles linking ecosystems across scales: from individuals’ traits, to the assembly of ecological networks, and the emergence of macroscopic spatial patterns. These findings contribute insights into how local and spatial dynamics interact to influence large scale properties of ecosystems. But they also lead to new questions about the rules of life, highlighting the strong need for a refinement of theoretical methods, more large scale field observations, and creative laboratory experiments that leverage modern technologies.

Identifying the mechanisms that drive the structure and dynamics of communities is a major challenge in ecology. Plant traits are being increasingly used to address this challenge as they provide insights into the critical phenotype-environment link. Such information is necessary to apply to questions regarding how forests are responding to changing environments and the implications of those changes for the long-term persistence of forests. In this talk, I will discuss how the use of trait-based approaches and different modeling tools has allowed me to address questions regarding the drivers that shape forests, and species responses to habitat loss and fragmentation.

Neotropical freshwaters house one of the greatest concentration of species and phenotypes on Earth, with more than 8,000 fish species representing approximately 10% of all living vertebrates combined, compressed into a tiny volume of aquatic habitat. The diversity of Neotropical freshwater fishes long predates the geological formation of the modern Amazon and Orinoco river basins, and the unparalleled diversity we observe today arose from an excess of speciation over extinction rates operating over a lengthy time period of tens of millions of years. In this paper we summarize the major phylogenetic and biogeographic dimensions of the Neotropical ichthyofauna, and review recent advances in understanding the roles of paleogeography, river capture, and other landscape evolution processes contributing to the formation of this singular fauna.

EEB Museums Friday Seminar: Historical ecology of Neotropical freshwater fishes (January 31, 2020 2:00pm) https://events.umich.edu/event/71087 71087-17774974@events.umich.edu Event Begins: Friday, January 31, 2020 2:00pm

This talk will provide a synoptic overview of a new book project now being prepared by the community of Neotropical ichthyologists entitled Historical Ecology of Neotropical Freshwater Fishes. The humid Neotropics is home to the greatest concentration of biodiversity on Earth for many groups of organisms, including continental (or freshwater) fishes. The full dimensions of Neotropical freshwater fish (NFF) diversity have only come to be appreciated in recent years. As of this writing we have described about 6,088 NFF species, in 854 genera, 95 families and 39 orders. From torrential headwaters cascading off the Andean cordilleras and upland cratonic shields, to the murky waters of large lowland river channels, floodplains and swamps, NFFs thrive in astonishing abundance and diversity. NFFs in fact represent the most species-rich – and species-dense – continental fauna on Earth. Recent years have also seen rapid increase in our knowledge of the phylogenetic and ecological dimensions of NFF diversity, and the adoption of many innovative methods to study and understand the historical ecology of this singular fauna. NFF species inhabit a broad range of aquatic habitats, ecoregions and climate zones, displaying a bewildering array of organismal phenotypes that potentially confer functional advantages. Many NFFs possess ecophysiological and behavioral traits and tolerances that promote co-existence in species-rich local assemblages, some of which may also enhance evolutionary diversification. Other specialized phenotypes of sexual communication systems, including sensory cues and courtship displays, inhibit species from hybridizing and therefore promote higher species richness of local assemblages. The goals of this book are to synthesize current information on the historical ecology of NFF taxa, and to document the phylogenetic history of the many distinctive ecophysiological phenotypes of these fishes adapted to diverse habitat, dietary and other life-history specializations.

Infectious disease results from interactions between parasites and susceptible hosts in the environment. For many populations, we have a limited understanding of the mechanisms that shape host susceptibility and how those mechanisms interact with ecological factors to regulate the spread of disease. Focusing on a simple one-host one-parasite system with environmental transmission, I use theoretical and empirical methods to explore the causes and consequences of variable host immunity. I demonstrate how integrating immune defenses into host-parasite interactions can improve our understanding of disease spread in natural systems.

The world is experiencing unprecedented transformation of nutrient flows through human action, with impacts accelerating including fisheries collapse, hypoxic dead zones, and polluted drinking water. Clearly, nutrient application produces a series of entangled and unintended consequences that suggests a fundamental imbalance in how we manage the planet. Interestingly, awareness that things are not what they might seem with nutrients appeared 50 years ago in the pages of Science, with Michael Rosenzweig’s seminal paper on the “Paradox of Enrichment “. Here, pushed by recent empirical findings of ecosystem imbalance occurring on the landscape we revisit Rosenzweig’s paradox of enrichment results from a more wholistic food web perspective and a large spatial perspective (meta-ecosystems). While many have argued against any empirical evidence for Rosenzweig’s paradox of enrichment in nature, when we broaden his work to include multiple types of instability in space we find that spatial food web theory suggests we expect to find ecosystem imbalances often at great distances from the local source of nutrient enrichment given natures vast transport systems (e.g., stream, rivers, oceanic currents, wind, mass migration events). The results also suggest an analog to network food web theory that stabilization of these large spatially distant ecosystem imbalances can occur by muting key spatial pathways of nutrient transport in meta-ecosystems.

Evolutionary quantitative genetics provides a strong theoretical framework for connecting evolutionary processes, the underlying genetic architecture of traits, described in terms of variances and covariances, and the pace and direction of multivariate evolution. In this talk I will discuss the importance of considering a multidimensional phenotype and the within-species (co)variation to understand trait dynamics in populations, in terms of evolvability (i.e., the ability of a biological system to respond to selection) and evolutionary constraints. I will explore the evolution of the cranial covariance structure and the average morphology in the most noteworthy example of adaptive radiation in mammals, the New World leaf-nosed bats, by combining phylogenetic comparative methods and quantitative genetic approaches.

There is a growing body of literature demonstrating the barriers and solutions to improve the successful selection, retention, and development of underrepresented (UR = low income, minority, and first generation) students in ecology and evolutionary biology & STEM fields in general. A model undergraduate training program will be presented that focuses on a growth mindset over traditional skim programs. This will be followed by recommendations for DEI around graduate school selection & training, and the last section of the talk will address on-going approaches to hiring diverse faculty, retention, and ways to establish DEI receipts for all populations.

The ability to evolve and adapt is a fundamental property of living systems. In many populations, the process of adaptive evolution can be thought of as an uphill walk of a population on a "fitness landscape" where mutations are steps and fitness is altitude. Understanding the structure of fitness landscapes is a fundamental open problem in evolutionary biology. I will discuss our efforts to probe the fitness landscapes and the adaptive walks on them using experimental microbial populations. I will show some interesting and perhaps somewhat counterintuitive patterns that we found. If time permits, I will say a few words about our initial attempts to build a theory that might help us understand these patterns.

The mating system, or who mates with whom, and how often, is a critical trait that influences the distribution of genetic variation among populations as well as fitness and the ability of populations to respond to selection. Although we know that the plant mating system is strongly influenced by environmental factors, we do not understand if and how the mating system may be shaped by anthropogenic forces. In this talk, I give a brief overview of the ongoing ecological genetics/genomics projects within the lab and focus on our attempts to understand how the mating system may evolve given regimes of strong human-mediated selection.

The resolution in genomic data makes it possible to not only detect divergent lineages, but also local population structure within them. Yet, these conflated boundaries have received little attention from those developing genetic-based species delimitation methods, potentially leading to mass over-splitting as genomic data become more widely employed. These challenges have profound implications for not only understanding the generation and dynamics of biodiversity, but also for conserving this diversity.

In this workshop, we will cover the foundations upon which genetic-based inference of species boundaries are built. In particular, we will review the history that lead to a reliance on the multispecies coalescent (MSC) as the primary model for species delimitation. Despite the appeal of genome-based species discovery, we will explain how misidentification of population structure as putative species is an emerging key issue for applications of the MSC for species delimitation, as well as the implications of divergence of gene flow for identifying species boundaries.

Watch for updates later this year.

The Department of Ecology and Evolutionary Biology at the University of Michigan is pleased to present Natural History Collections: Drivers of Innovation, an exciting symposium about innovative and unconventional uses of biological collections across scientific disciplines. The symposium events will take place from the 13-15 March 2020, on the campus of the University of Michigan in Ann Arbor.

When biologists think of natural history collections, most tend to think of taxonomy and systematics, yet many are unaware of the uses of biological collections beyond those traditional fields. These studies span the breadth of the tree of life and address broad subjects that span comparative genomics to bioengineering and climate change to historical pathogen dynamics, among many, many more. As stewards of one of the largest university-based biological collections in the world, we are in an extraordinary position to leverage our holdings of biological material from the last century or more. We envision this symposium as a way to showcase the often-unrealized opportunities and non-traditional avenues of research that our collections make possible to the entire scientific community, and emphasize some of the interdisciplinary ways in which our collections are being or could be used. We hope to foster a broader understanding and expanded use of an incomparable resource that the University of Michigan has cultivated for the past two hundred years.

The symposium will feature both established and novel uses of natural history collections across a wide range of taxonomic groups, systems, and time. Our goal is to create a program with contributions from all corners of ecology and evolutionary biology. The program will include two keynote talks by senior speakers and additional talks by early-career speakers.

The diverse ‘museum and museum-like’ collections of Tier 1 Research Universities, as those at RMC and the Matthaei-Nichols, have pivotal roles in the emerging protocols of Tribally-engaged research outside the biomedical sciences. At UM, in addition to each unit’s intellectual and disciplinary agendas, our Tribal engagements profoundly influence other core functions of the university: from undergraduate recruitment to donor and foundation relationships. Based on more than 15 years of relationship-building, Michener has developed UM Matthaei-Nichols as a key partner in broadening and refocusing plant- and environmental justice-centered research relationships with Michigan’s Tribal partners. The ways forward include deepening engagement with the research divisions at RMC. By mutual agreement with Tribal partners, little of this work has been discussed in public venues until recently. Today’s talk will focus on specific Tribally-engaged research activities at the Matthaei-Nichols, their immediate objectives, and the anticipated impacts for all partners.

Defense: Investigating the Role of Sleep-Dependent Memory Consolidation in Experience Activated Neurons (March 27, 2020 3:00pm) https://events.umich.edu/event/73916 73916-18424548@events.umich.edu Event Begins: Friday, March 27, 2020 3:00pm

Sleep is critical for memory consolidation, yet the mechanisms which underlie this process are not well understood. There are two main hypotheses on how sleep promotes memory consolidation: the Sleep Homeostasis Hypothesis (SHY) and Active System Consolidation (ASC). SHY posits that during waking experience, the brain forms new memories – creating and strengthening synapses. Unregulated, this process could reach a point of saturation, which would be metabolically expensive and occlude new memory formation. SHY hypothesizes that during sleep, synapses are uniformly scaled, eliminating weak connections while stronger synapses (important memories) persist. In contrast, ASC postulates that sleep synchronizes neural firing, selectively activating (and strengthening) synaptic connections for specific memories – promoting consolidation. Thus, according to the two hypotheses, different synaptic changes are expected across sleep.

Unresolved discrepancies between ACS and SHY may be due to technical limitations. Until recently, techniques have been unavailable to characterize and manipulate the neurons involved in a specific memory. Experimental outcomes have historically relied on data averaged across the neurons in a given brain structure. This lack of resolution has been a major barrier to understanding how sleep promotes memory consolidation. To move beyond these limitations, this thesis employs both in vivo recording of neurons (allowing tracking of memory encoding neurons across behavioral states) and recently developed engram, or memory trace, tools (allowing us to manipulate the activity of neurons encoding a specific memory). These experimental strategies aim to clarify whether SHY or ASC (or both) occur in primary visual cortex (V1) during post-learning sleep, and whether this consolidation is dependent on sleep-specific memory reactivation.

Using neuronal firing rates as a measure of plasticity, we examined the activity of V1 neurons across sleep, sleep deprivation, and post-learning sleep. The learning paradigm used is orientation-specific response potentiation (OSRP) which manifests as selective increases in V1 neuronal responses to a specific orientated grating. All sleep conditions showed an upregulation in the activity of low firing rate neurons and a downregulation of the activity of high firing rate neurons. These low firing rate neurons convey more visual information and selectively express OSRP. This suggests that sleep selectively upregulates the activity of neurons involved in sensory experience while simultaneously downregulating the activity those that are not.

To evaluate the necessity of memory reactivation during sleep for consolidation, we used engram technology to selectively manipulate neurons activated by a specific visual stimulus. We combined visually-cued conditioning to oriented gratings with engram labelling to create a tractable system for manipulating a specific memory during sleep. We show that the TRAP (targeted recombination in active populations) engram mouse line can be used to drive transgene expression in a specific oriented grating ensemble in primary visual cortex. We then inhibit this ensemble during post-conditioning sleep causing impaired consolidation. This was done in a content specific manner without altering sleep architecture or oscillations - indicating that reactivation specifically is necessary for sleep dependent memory consolidation.

This work unites two long standing hypotheses regarding sleep function for brain circuitry - SHY and ASC. The data support a comprehensive model in which sleep selectively reactivates neurons encoding relevant information. This upregulates their activity, while simultaneously decreasing activity in neurons whose information content is not salient. Future work will be needed to understand the molecular, cellular, and network mechanisms which drive these changes in specific cell populations.

The events that occur during reproduction play a critical role in determining the distribution of genetic and phenotypic variance within populations and thus their potential to adapt and persist. Understanding the forces shaping the evolution of mating patterns and the diversity of traits that influence mating success in the natural world is a fundamental problem in evolutionary biology. Plants, in particular, show an impressive amount of diversity in floral form and the degree to which they outcross or self-pollinate. In this seminar, I will share a series of empirical and modeling studies investigating how the pollination environment drives the evolution of floral traits that promote either outcrossing or selfing.

Abstract: Intrinsically photosensitive retinal ganglion cells (ipRGCs) are responsible for non-image-forming functions such as circadian photoentrainment, pupillary light reflex and the suppression of melatonin. Additionally, their axons innervate two main image-forming visual nuclei: the superior colliculus (SC) and the lateral geniculate nucleus (LGN). Furthermore, electrophysiology data discovered that ipRGCs signal to dopaminergic amacrine cells via AMPA/Kainate glutamate receptors and to displaced amacrine cells (ACs) located in the ganglion cell layer of the retina through gap junctions. Retinal ganglion cells had never been found to signal intraretinally prior to this finding.

Several labs have been exploring how ipRGCs mediate or modulate image-forming vision through their central projections and signaling to dopaminergic ACs. However, little is known about the functional roles of gap-junction signaling from ipRGCs to displaced ACs and how ipRGCs work in conjunction with rod and cone photoreceptors to mediate image-forming visual responses. Neurobiotin tracer injections, immunostaining, and optokinetic visual behavior techniques were used in this thesis to fill in this knowledge gap. Four specific aims were accomplished: 1) understand how ipRGC-coupled ACs are distributed across the retina and identify ipRGC-coupled ACs, 2) test the hypothesis that connexin36 (Cx36) couples ipRGCs to displaced ACs, 3) examine the effect of glutamatergic input on ipRGC-AC coupling, and 4) assess the effect of rods, cones and melanopsin on image-forming behavior.

We found that all six ipRGC types are electrically coupled to amacrine cells, primarily via Cx36 and a few ipRGC-coupled amacrine cells are bNOS, nNOS, NPY or 5-HT immunopositive. ipRGC-AC coupling is enhanced in the presence of NMDA receptor expression in ipRGCs. We found the distribution of ipRGC-coupled amacrine cells is region specific, and rods, cones and melanopsin contribute to image-forming vision differently. Because ipRGCs remain light-sensitive in many blind patients suffering from rod and cone degeneration, a better understanding of the signaling ipRGCs could lead to novel strategies to restore sight in such patients.

Humans, like many other species, show striking sex differences in immune function. While the proximate determinants of sex differences across species can include both chromosomal and hormonal differences, the ultimate evolutionary determinants will be rooted in differences in investments in competing and caring between the sexes. Ultimate explanations have classically been framed in terms of quantitative sex differences in immune function (with males typically the ‘weaker’ sex), but have failed to account for qualitative sex differences in immune function. We model immune trade-offs that might underpin these differences. Once the dangerous side of immunity is accounted for, two distinct immunological profiles emerge as peaks on a fitness landscape, one aligned with investment in pathogen detection and the other with investment in pathogen killing. Intriguingly, alignment of these fitness peaks with observed sex differences in birds and mammals – where females typically favor detection – cannot be explained by selection pressures emerging from models including immunity trade-offs alone. Age-specific patterns of infection, and/or maternal transfer of immunity (e.g., maternal antibodies) are also required. The characterization of immune function underlying these predictions is necessarily a simplified caricature of the true complexity. We develop projections of the scope of expectations of this simplified caricature in terms of the development of immunity across the life course in the two sexes.

With the existential crisis of our time, climate change, bearing down upon us, there is a need to develop constructive and sustainable solutions. Great strides have been made in generating awareness about climate change, overpopulation, mass extinction of species and other stressors on the environment. In 2019, the City of Ann Arbor declared a Climate Emergency. But how can we as individuals make a difference? Buddhism has always emphasized the interdependence of all living beings and the benefit of interacting compassionately.

https://umich.zoom.us/j/91327991777?pwd=UnVlZ21EWm1ZUmU4d0EzUGRVRVJqQT09

We are in a time of rapid climate change. Though we have developed policies such as the Kyoto Protocol and the Paris Agreement, and we have made substantial progress on the use of renewable energy, atmospheric carbon dioxide emissions continue to increase. Therefore, the evidence suggests we will not disrupt the observed climate trends in the foreseeable future.

For the past decade, Dr. Rood has been part of a team of social scientists, climatologists, and practitioners focused on the usability of climate knowledge. From this work, we have developed models of engagement to advance usability. Successful use of climate knowledge, often, relies on multi-constituency problem solving with climatologists working interactively to develop meaningful fits between climate data and knowledge and the practitioner’s needs.

This talk highlights the framing of the challenges of climate change and the behavioral changes that will be required to allow us to navigate through those changes.

Dr. Anton Reznicek (Curator of Vascular Plants at the U-M LSA Herbarium) will deliver the annual UMBS Bennett Endowed Lecture in Plant & Fungal Ecology.

It has become routine to predict the future of our biota by starting with present day distributions and broad-brush niches derived from these occurrences. Looking to the past and basing predictions on what has actually happened would seem to be very helpful in understanding the nature of the changes and refining approaches to studying change, but for plants we are typically hampered by lack of past floristic data. This is usually because we have little or no detailed information for floras before large scale European alteration of the landscape. Michigan, however, is unique in that immediately after becoming a State, in 1837, the State legislature, advised by forward thinking scientists, established the First Geological Survey of Michigan. The core idea was to produce detailed information on Michigan’s natural resources to provide a scientific foundation for the development of the State. Because at this time essentially all medicine was plant based, a detailed inventory of the Flora, supported by herbarium specimens, was a major thrust of the First Survey. Collating and studying this material laid the groundwork for understanding of our past flora in unusual depth. Three segments of this knowledge will be the primary focus. First, a review of the First Survey’s collecting activities (and those of a few other early collectors) and what we thus know about Michigan’s Flora in 1840. Second, a review of changes that have occurred that bring us, 180 years later, to the composition of our present day flora. In terms of species loss, this has been driven mostly by direct physical alteration of habitats, either complete elimination or drastic alteration of the hydrology and microhabitat conditions, especially in southern Michigan. Finally, knowing the operation of the past drivers of change, what can we infer about the changes we can expect in the
future?
