Haiqing Xu defends his dissertation

Although the expression stochasticity of an individual gene is unavoidable, clustering of genes promotes the synchronization of their expression fluctuation. This phenomenon provides a fitness benefit when the expression ratio of the clustered genes needs to stay constant, for example, because of the accumulation of toxic compounds when this ratio is altered.

ABSTRACT: Untangling the interaction between genotype, environment, and phenotype represents a central goal of evolutionary biology, yet a comprehensive understanding of the relative influence of each remains elusive, especially in non-model systems. My research uses several approaches for investigating the multiple sources of variation that can impact observed phenotypic traits. I highlight how functional traits impacting dispersal ability in Caribbean mangrove species, when coupled with spatially explicit ocean current data, can lead to crucial insights about how genetic variation was shaped by the environment. Especially in periods of rapid climate change, environmental pressures can impact the adaptive nature of traits, and in some cases, adaptive variation can transcend species boundaries. Using a case of recent (i.e., Pleistocene) hybridization in montane sedges, I illustrate how genotype-environment association analyses identify adaptive loci with respect to environmental gradients that overwhelmingly correspond to loci with excess ancestry from one parental lineage. Digitized museum specimens may represent an efficient way to study the interaction of genome, phenome, and environment; I propose an analytical framework for explicitly quantifying the covariation of genomic, phenotypic, and environmental data from thousands of conspecific specimens.

Our lecture series is free and open to the public, allowing interested community members to learn more about the natural world, and the Biological Station.

Pettingill Endowed Lecture in Natural History - Global change impacts on forest ecosystems: Amplifying Indigenous voices to find community-driven solutions

Eastern US forests are losing a foundation tree species, the eastern hemlock (Tsuga canadenis), due to the exotic insect pests hemlock woolly adelgid (Adelges tsugae) and elongate hemlock scale (Fiorinia externa). The widespread destruction of this important evergreen conifer has large ramifications for ecosystem processes and other species that depend on it for survival. Using an "accidental experiment" initiated by patch-level timber harvesting ~30 years ago in western Massachusetts, Dr. Ignace will present the impacts on source/sink carbon dynamics, which may be exacerbated by a warming climate. Building on this framework, she will discuss how we can center Indigenous voices and knowledge to fully understand local land use history. Going beyond the peer-review publications and moving to include many forms of writings, knowledge sharing, artwork, and communication will be needed to find community-driven solutions to environmental problems.

Abstract
Freshwater Unionid bivalves have recently faced ecological upheaval through pollution, barriers to dispersal, human harvesting, and changes in fish-host prevalence. Currently, over 70% of species are threatened, endangered or extinct. To characterize the genetic response to these recent selective pressures, we collected population genetic data for one successful bivalve species, Megalonaias nervosa. We identify megabase sized regions that are nearly monomorphic across the population, a signal of strong, recent selection reshaping genetic diversity. These signatures of selection encompass a total of 73Mb, greater response to selection than is commonly seen in population genetic models. We observe 102 duplicate genes with high dN/dS on terminal branches among regions with sweeps, suggesting that gene duplication is a causative mechanism of recent adaptation in M. nervosa. Genes in sweeps reflect functional classes known to be important for Unionid survival, including anticoagulation genes important for fish host parasitization, detox genes, mitochondria management, and shell formation. We identify selective sweeps in regions with no known functional impacts, suggesting mechanisms of adaptation that deserve greater attention in future work on species survival. Our work suggests that duplicate genes are an essential source of genetic novelty that has helped this successful species succeed in environments where others have struggled. These results suggest that gene duplications deserve greater attention in non-model population genomics, especially in species that have recently faced sudden environmental challenges.

Abstract
A key factor limiting our understanding of early crown bird evolution is a complex history of molecular evolution linked to the Cretaceous–Paleogene (K–Pg) mass extinction and associated changes in life history parameters. Here, we assess molecular heterogeneity across crown bird phylogeny using a new technique, enabling inferred sequence substitution models to transition across the history of a clade. Our approach identifies contrasting patterns among exons, introns, untranslated regions, and mitochondrial genomes that reflect distinct regimes of molecular evolution across the avian phylogeny. Up to fifteen molecular shifts map to rapidly diversifying clades near the end-Cretaceous boundary, demonstrating an "early burst" of genomic disparity. Using simulation and machine learning techniques, we show that shifts in developmental mode or adult body mass best explain transitions in the mode of nucleotide substitution. We further connect these patterns to macroevolutionary shifts in the allometric scaling relationship between basal metabolic rate and body mass. In agreement with theoretical predictions, we show that this scaling relationship became weaker across the end-Cretaceous transition. Thus, our study provides evidence that the Chicxulub bolide impact triggered integrated patterns of evolution across avian genomes, physiology, and life history that structured the evolutionary potential of modern birds.

Abstract
Every organism is confronted with endless amount of challenges during its lifetime. Some of the challenges can be avoided, for others the organism is prepared for (due to evolutionary adaptation), but most of those challenges turn out to be costly to confront. In such cases the focal organism frequently faces a trade-off – necessity to pay for improvement in one trait with deterioration in another trait.

Daphnia is almost constantly found between a rock and a hard place, and yet it is ubiquitous and dominates most of the lakes and ponds. It’s resilience to variety of environmental challenges stems from some impressive adaptations, enormous phenotypic plasticity, and mastery in performing beneficial trade-offs. During the seminar I will present some of the fascinating ways in which Daphnia avoids or mitigates threats like changing climate, parasitism or predation.

Abstract:
A single genome appears to be a cohesive community of distinct genes with common incentives. Across development, genes collaborate to build a robust and fertile individual. Across evolution, genes accumulate adaptive DNA sequence changes that build an even more robust, and even more fertile, individual. The more robust and fertile the individual, the more copies of all these genes in the next generation. In this way, our genome’s distinct genes contribute to a communal good. However, much of our DNA actually serves no beneficial function. Most of this DNA has minimal effect on our health and fertility; consequently, natural selection fails to efficiently purge it from our genome. Some of this DNA harms us. This so-called “selfish DNA” acts akin to viruses, hijacking our cell’s machinery to make more copies of itself. While most viruses achieve evolutionary success upon transmission from one individual to another, these selfish elements achieve evolutionary success by increasing their own genomic copy number from one generation to another. When selfish elements win, the rest of the genome loses. Compromised Darwinian fitness puts evolutionary pressure on our genome to police these elements. Selfish DNA fights back with counter-adaptations, escalating a “molecular arms race.” In my seminar, I will describe my lab’s efforts to define the identity, molecular mechanisms, and biological consequences of such genetic conflicts between genomic hijackers and genomic guardians. To gain these insights, we generate interspecies swaps of adaptively evolving proteins that package the rapidly evolving repetitive DNA around
the telomeres and centromeres of Drosophila melanogaster. Using cell biology, next generation sequencing, and classical genetics, we probe how intra-genomic conflict between genes and DNA repeats shapes the evolution of genome integrity.

Our weekly lunch seminar series featuring internal speakers in the field of ecology and evolutionary biology.

Abstract
Astragalus L. (Fabaceae) is possibly the most species-rich genus of seed plants with more than 3,000 recognized species. Almost 500 of those species (commonly called milkvetches or locoweeds) in the Americas are part of a clade called Neo-Astragalus and are estimated to have shared a common ancestor as recently as 4.5 million years ago. However, as largely temperate, perennial herbaceous plants, these species are rather ecologically similar compared to classic examples of plant adaptive radiations. Using phylogenies estimated from whole chloroplast genomes and nuclear ribosomal DNA, I will explore cryptic (or difficult to observe) differentiation in Neo-Astragalus by examining character evolution and homoplasy in morphological traits as well as the accumulation of selenium. About two dozen Neo-Astragalus species are selenium hyperaccumulators that are not only restricted to soils already rich in the element but also accumulate it to the point they are highly toxic to most herbivores. Convergent evolution in this trait could be indicative of other kinds of cryptic but ecologically important disparity that may have developed during the evolution of Neo-Astragalus in the Americas and in Astragalus as a whole.

Our weekly lunch seminar series featuring internal speakers in the field of ecology and evolutionary biology.

Abstract
Tropical seagrass ecosystems are among the most productive ecosystems worldwide, yielding tremendous services for coastal communities. Yet, they are among the most impaired from anthropogenic stressors. Understanding factors controlling primary production is fundamental for the protection, management, and restoration of these ecosystems. Artificial reefs are a widely used marine management tool, creating biogeochemical hotspots via aggregating fish that fuel local primary production. However, testing whether increased local production affects primary production at ecosystem scale remains empirically challenging. Thus, we implemented a spatially explicit individual-based simulation model to test how aggregating fish on artificial reefs affect seagrass primary production at various scales.

Our weekly seminar series featuring internal and external speakers in the field of ecology and evolutionary biology. This seminar will be in-person and livestreaming on Zoom (link this page).

Abstract:
RNA viruses have exceptionally high mutation rates, on the order of one new mutation per replication cycle. These mutation rates are frequently invoked to explain the ability of these viruses to rapidly adapt to new or changing environmental conditions, such as changes in host immunity profiles for endemic viruses such as influenza and changes in host species in the case of spillover viruses. Here, I will instead focus on the evolutionary constraints to viral adaptation that are brought about by high mutation rates in the context of spatial within-host viral compartmentalization, transmission bottlenecks between infectors and infectees, and genetic linkage across viral genomes. I will also discuss means of population-level viral adaptation that are accessible in the context of these constraints. The empirical examples I will draw on will include influenza viruses and SARS-CoV-2.

Our weekly lunch seminar series featuring internal speakers in the field of ecology and evolutionary biology.

Abstract
Sex chromosomes typically evolve through the gradual reduction of recombination between chromosome pairs that have acquired a sex-determining region. Many plants have "younger" sex chromosomes than amniotes, and therefore offer valuable insight into this process. Heartwing sorrel (Rumex hastatulus) has a polymorphic sex chromosome karyotype resulting from a chromosome fusion. This natural variation allows direct comparison of a sex chromosome and its autosomal homologue. We use a recent genome assembly and genetic map to explore how recombination evolved in this species and how that challenges standard models of sex chromosome evolution.

Our weekly seminar series featuring internal and external speakers in the field of ecology and evolutionary biology. This seminar will be in-person and livestreaming on Zoom (link this page).

Abstract:
Anthropogenic land and other resource use is a major force shaping the abundance, distribution, and evolution of species. It often disrupts historically contiguous habitats, resulting in patchier and smaller fragments which can limit dispersal and gene flow. Populations experiencing such conditions can face elevated risks for inbreeding depression and diminished adaptive capacity. Wildlife managers use various and often multifaceted approaches including habitat restoration, translocations, breeding programs, and demographic monitoring to mitigate extinction risk for species with small, fragmented populations. I will focus on how genomics can be used to gain deeper understanding of the demographic outcomes of these practices and the value of looking under the hood in this way for assessing population fitness using federally Threatened Florida Scrub-Jays as an example. Secondly, I will discuss the prospect of using biclustering algorithms for identifying loci that may contribute to genetic load and the potential of applying this approach to enhance the recovery of the federally Endangered Poweshiek skipperling.

Our weekly lunch seminar series featuring internal speakers in the field of ecology and evolutionary biology.

Abstract
Climate change is impacting temperature and moisture conditions across the seasons in montane meadows, from accelerating snowmelt date early in the growing season to greater drying of the soil in the later part of the growing season. Though there are distinct impacts throughout a growing season, we know little about how climate change will impact ecosystem function, such as productivity and nutrient cycling, beyond when these processes are typically measured during peak seasonal productivity. Additionally, a growing body of work acknowledges the linkage between plants and soil and shows that an impact on one has cascading effects on the other either bottom-up or top-down. During the seminar, I will discuss how climate change, through abiotic and biotic effects, is impacting plant and soil conditions at a fine-scale resolution throughout the growing season.

Abstract:
Corals and their relatives are some of the most ecologically important metazoans on earth, from shallow waters to the deep sea. With ocean conditions changing at rates faster than previously recognized, we must determine the factors that shape coral diversity across depth, space, and time. And because the drivers of marine diversity are poorly known in the largest environment on earth—the deep sea—I often focus my questions on processes that generate deep-sea coral diversity. Therefore, with collaborators across the world, I am combining genomic approaches with museum specimens and ocean exploration to rebuild the coral tree of life and answer fundamental questions regarding coral diversity.

Our weekly lunch seminar series featuring internal speakers in the field of ecology and evolutionary biology.

Abstract
Maximizing the growth and productivity of commercial plantations is critical for meeting global demands for wood and paper products, without resorting to unsustainable harvesting of native forests or increasing the plantation estate at the expense of other primary production systems. Because Eualyptus plantations are often established on nutrient-poor soils in Australia, optimizing fertilizer use is an important management tool for maximizing in these systems. To improve site-specific fertilizer regimes, a more detailed mechanistic understanding of the productivity response to nutrient supplementation under varied abiotic conditions is needed. Here, I present a conceptual framework explaining the interplay between nutrition, leaf area dynamics, physiological processes and growth, based on the results of three large-scale field fertilizer experiments in E. nitens plantations in Tasmania, Australia. I present several lines of evidence that large applications of nitrogen exacerbates water stress and hence reduces productivity in warm and dry conditions.

Abstract
Since the Mid-Miocene Climatic Optimum, the Earth has substantially cooled, exposing flowering plants to new ecological opportunities that they can adapt to. Cold-tolerant angiosperms possess fascinating adaptations and trait innovations that enable them to survive under extreme climates. Montane angiosperms, a special subset of cold-tolerant plants, are well-known for their independent instances of rapid radiation. During this talk, I will discuss my proposed dissertation research, a global analysis of the correlation of montane distribution and speciation rates across major orders of flowering plants including a phylogenetic simulation comparing the macroevolutionary effects of differing turnover rates. Also, with available transcriptome data, I will examine the effect of whole genome duplications and gene duplications on the cold adaptations of alpine-arctic lineages in Caryophyllaceae.

Our weekly seminar series featuring internal and external speakers in the field of ecology and evolutionary biology. This seminar will be held virtually on Zoom (link this page).

Abstract:
As climate change threatens global biodiversity, it has become increasingly clear that evolutionary processes will play an important role in species persistence through the next century. My lab uses genomic tools, paired with ecological experiments and large-scale climate data to understand the genomic mechanisms underlying adaptation to different climate regimes, with the ultimate goal of integrating evolution into predictive frameworks. In this talk, I will discuss past and ongoing work addressing patterns and predictions for climate adaptation in marine foundation species.

Abstract:
All-female salamanders in the genus *Ambystoma* are the oldest unisexual vertebrates, composed of a single mitochondrial lineage and multiple nuclear genomes introgressed from other salamander species. The unique characteristics of this system provide interesting perspectives on the maintenance of sex and polyploidy. Our work combines genomics, physiological, and ecological approaches to understand how all-female salamanders have co-existed with related sexual species, how their numerous nuclear genomes have moved between lineages, and how the interactions between their mitochondrial and nuclear genomes influence their basic physiology.

Our weekly seminar series featuring internal and external speakers in the field of ecology and evolutionary biology. This seminar will be in-person and livestreaming on Zoom (link this page).

Abstract:
From individual growth and survival to the ecological trajectories of populations to the social and culture fabric of society, food plays a pivotal role in shaping life on Earth. As climate continues rapidly changing and more complex human-environment interactions emerge, it has become even more important to understand how these relationships shape the ecological processes that maintain the structure and function of ecosystems and the goods and services they provide. In this talk, I will explore a series of interconnected case studies on food web dynamics in coral reef socio-environmental systems, which hold some of the highest biodiversity in the world, provide food for ~1B people, and support >$375B in global goods and services. I plan to show how taking a molecular approach to food web ecology can shed light on some fundamental questions in ecology while providing scientific support to address current and emerging ocean challenges. Through this process, I want to highlight the need and value to think about ecology in a decolonized context that centers the voices, experiences, and ways of Indigenous communities who steward >80% of coral reefs globally.

Abstract: Rates of trait evolution vary markedly across the tree of life, from the accelerated evolution apparent in adaptive radiations to the remarkable evolutionary stasis exhibited by so-called "living fossils". Identifying and understanding the causes and consequences of such "rate heterogeneity" has critical implications for robustly testing evolutionary hypotheses and, more generally, elucidating how and why levels of phenotypic diversity vary across space, time, and taxa. For my dissertation, I am developing novel phylogenetic comparative methods for inferring variation in rates of continuous trait evolution. These methods will fill key gaps in the comparative biologist's toolkit and provide researchers with more power and flexibility in exploring and dissecting rate heterogeneity across the tree of life.

Abstract:
In this talk I will summarise collaborative efforts from my research group to unveil the patterns and processes underlying the outstanding biodiversity found today in the world’s tropical regions, with a focus on the American tropics and additional examples from Africa and Madagascar. By comparing the current distribution and evolutionary history of multiple organism groups, we have been able to identify common effects of historical events (such as mountain uplift, climate change and river shifts) on biodiversity. To our aid we use molecular and spatial information from field collected specimens and natural history collections, develop new computational tools and review fossil evidence. I will then discuss how the information we are gaining from the past may help predict the future and identify priorities for conservation in a time of escalating biodiversity loss due to the expansion of agriculture, climate change, invasive species and unsustainable exploitation of natural resources.

Abstract:
Soils contain the most diverse community of organisms in terrestrial ecosystems, with essential roles in nutrient cycling and food-web dynamics. Human-induced disturbances remain a significant threat to the structure and functioning of soil food webs, yet our understanding of how they respond to environmental change is limited. I present two examples (i.e., plant invasion and resource subsidies) of how environmental change can influence soil food web dynamics. First, I show how garlic mustard (Alliaria petiolata)—a widespread North American plant invader—affects soil food webs by altering fungal composition and biomass. In a second example, I show how aquatic insect subsidies can affect subarctic food webs by adding novel resources, resulting in increased microbial activity, litter decomposition, and plant biomass. Together these two examples illustrate that soil food webs are highly sensitive to resource changes in the environment, leading to shifts in ecosystem processes and plant community dynamics.

Abstract:
Pathogen evolution presents a continuously moving target for modern medicine. Biomedical interventions like vaccines and targeted drugs are cornerstones of modern life and medicine. In isolation, however, these costly and reactive approaches aimed at eradicating bacteria concomitantly select for more virulent and resistant variants and ultimately, ease their spread. Interventions that are informed by evolution and ecology have the potential to confront the largest sources of preventable death in the US and will play a key role in the future of personalized medicine.

Metabolic adaptations precede and facilitate pathogen evolution by offsetting the fitness costs of energetically expensive traits like virulence, transmission, and drug resistance. Despite understanding the basic molecular mechanisms governing metabolic-specific adaptations to various drugs, we remain far from accurately predicting their effects on pathogen evolution to tailor metabolic-based therapeutics. My research seeks to close this gap by developing and empirically testing multi-scale mathematical models to understand how metabolic adaptations influence the fitness landscape and evolutionary trajectory of pathogens.

TALK TITLE:
Developing frameworks for correlated character evolution in phylogenetic comparative modelling

PREVIEW:
The astounding diversity of life is the result of billions of years of evolution. And while the results of evolutionary change are evident in the world around us, the underlying processes that generated them are yet to be fully revealed. Hypotheses about how these processes play out over millions of years are often tested with phylogenetic comparative methods (PCMs). PCMs combine present-day observations with knowledge of how species are related to one another to test hypotheses of unobserved evolutionary change. However, major methodological gaps exist both in terms of outstanding problems within current models and limitations to the types of datasets that are even analyzable. In this talk I will outline some of the challenges facing models of correlated character evolution and discuss some possible solutions. I will end the talk by discussing the potential for Artificial Intelligence to help understand the evolution of highly complex characters.

Abstract:
Research in our lab asks how nervous systems can be both strikingly flexible and remarkably robust, and how these phenomena simultaneously give rise to widespread similarities and incredible diversity in behavior. We use integrative approaches to address these questions across levels of biological organization and timescales, using charismatic frogs as a model system. The talk will provide a conceptual framework as well as data-driven background for ongoing projects in the lab, exploring mechanisms of inter- and intra-specific variation in parental behavior and juvenile aggression in poison frogs.

Rachel Green began her scientific career majoring in chemistry as an undergraduate at the University of Michigan. Her doctoral work was performed at Harvard in the laboratory of Jack Szostak where she studied RNA enzymes and developed methodologies for evolving RNAs in vitro. She came to the Johns Hopkins University School of Medicine in 1998 following post-doctoral work in Harry Noller’s lab at University of California Santa Cruz where she began her work on ribosomes. Her laboratory is interested in deciphering the molecular mechanisms that are at the heart of protein synthesis and its regulation across biology. Most recently, her work has focused on ribosome-mediated quality control systems that are triggered on difficult-to-translate mRNA sequences deriving from genetic or environmental insults. She has found that such translational distress leads not only to mRNA-specific QC events, but also to the activation of cell-wide signaling and transcriptional responses, mediated by factors that specifically bind to colliding ribosomes. Her laboratory uses both biochemical, genetic, proteomic and genomic approaches to get at these questions in bacterial and eukaryotic systems.

She is a Bloomberg Distinguished Professor of molecular biology and genetics at the Johns Hopkins University School of Medicine and a HHMI Investigator.

Lecture is made possible by a gift from her family in memory of Priscilla Connell, a renowned nature photography.

Our weekly lunch seminar series featuring internal speakers in the field of ecology and evolutionary biology. This seminar will be in-person and livestreaming on Zoom.

Abstract:
Ecological communities have been shifting rapidly under recent climate change with alarming consequences for biodiversity and ecosystem services, yet the generality and causality of such shifts have to be demonstrated. We focus on grasslands in the California Floristic Province, a global biodiversity hotspot spanning 300,000 km2, where considerable climate warming and drying have occurred. We compiled long-term grassland community composition data from 12 observational sites and a warming experiment, estimated hundreds of species’ climate niches from millions of occurrence records, and analyzed changes in community composition and species gain and loss in reference to their climate distributions. We show that these grassland communities experienced significant shifts toward species tolerant of warmer and drier conditions, at a pace similar to climate warming and drying. The consistent observational and experimental evidence establish grassland community shift as a predictable fingerprint of climate change.

Abstract:
Understanding the role of climatic gradients shaping species interactions and system-level structure and function has been the thrust of ecological studies. We are exploring how experimental warming and drought shapes the structure and function of montane meadows and temperate prairies. By tracking individual abundance and functional traits across plant communities, alongside ecosystem carbon dynamics, we address how climatic change influences prairies
and meadows across levels of biological organization. We find that while individuals and communities are shifting under climatic change, ecosystem functions lag behind.

Abstract:
In this presentation I'll discuss 1) the biological responses of riparian species facing climate change, 2) the barriers preventing Black women from entering natural resource careers, and 3) alternative educational approaches that could encourage Black girls to pursue careers in natural resources. First, I investigated the impact of stream drying on riparian lizards in southeastern Arizona. Although this study did not detect aquatic invertebrates as significant prey items for our study species, it is likely they are benefiting at least indirectly from stream water. Second, we examined barriers experienced by Black women and found three primary types of barriers they face are structural, socioeconomic, and cultural. Finally, I developed: Black (girls) Outside Leadership Development (BOLD). We found that it's crucial to provide middle school aged Black girls with experiences to learn about natural resources careers and the resources to pursue these careers when they are ready.

Abstract:
The Caribbean is one of the most well-studied biodiversity hotspots, but the diversity of today’s Caribbean is only a fraction of what once existed there, as natural and anthropogenic processes have contributed to extinction and extirpation across multiple taxonomic groups. Given this long-term history of environmental perturbations and human impacts, paleobiology is well-suited to inform ongoing conservation needs in the Caribbean, which continues to be impacted by habitat degradation, species introductions, and other global change phenomena. I show how fossil, archaeological, and ecological data elucidate patterns of biodiversity loss and resilience, with direct implications for conservation management. While conservation paleobiology has significant potential in the Caribbean, it also faces major challenges in implementation, in part due to colonial histories and practices of parachute science. I summarize how this colonial legacy perpetuates knowledge and resource gaps, and outline ways in which we can move toward an equitable conservation paleobiology in the Caribbean and elsewhere.

The Department of Ecology and Evolutionary Biology (EEB) at the University of Michigan invites you to attend the 18th Annual Early Career Scientists Symposium (ECSS). This year, we are excited to announce the theme “Global Change and its Consequences for Green Life.” Green life (i.e. plants, algae, microbes) form the basis of productivity in most ecosystems. Understanding how environmental change can impact the ecology and evolution of green life on earth is critical to the future of most communities, ecosystems, and human societies.
The theme includes, but is not limited to:
1. Direct and indirect impacts of environmental change on green life survival, reproduction, and distribution
2. How green life can buffer the impact of global change
3. Evolutionary responses of green life to environmental change/stress
4. Green life functional traits and their environmental correlates
5. Agroecology

The 2023 ECSS will be held on the 31st of March 2023 at the University of Michigan Matthaei Botanical Garden in Ann Arbor, MI. Six early career scientists will be selected to present their work, and two keynote speakers will be featured. The symposium will also have an afternoon poster session with featured lightning talks and ample time for networking during coffee breaks.

For the chosen talks, we consider early career scientists as senior graduate students (who stand to receive their Ph.D. within two years), postdoctoral researchers, faculty or staff scientists within their first or second year, and researchers at equivalent career stages who are not affiliated with an academic institution.

Our weekly seminar series featuring internal and external speakers in the field of ecology and evolutionary biology. This seminar will be in-person and livestreaming on Zoom (link this page).

Abstract:
To fully understand the macroevolutionary factors that have promoted the diversification and persistence of biological diversity varied tools and disciplines must be integrated. By combining data from several fields including molecular phylogenetics/phylogenomics, comparative genomics, biogeographic range reconstruction, stable isotope analyses, and microbial community sequencing to study the evolutionary history of the insects, we are beginning to understand the drivers of speciation and the interconnectedness of life. Comparative phylogenetic analysis reveals the interconnectedness of ants and plants and that ants diversified after the rise of the angiosperms. While studies combining stable isotope analysis to infer the trophic ecology of the ants and next-generation sequencing of gut-associated bacteria of ants highlight the importance of this microbiome association in the evolution of herbivory. Microbial contributions to ants are not limited to diet enrichment and we find evidence for their role in cuticle formation. These multiple lines of evidence are illuminating a more complete picture of ant evolution and providing novel insights into the role that symbiosis plays to promote biological diversity.

The discovery of Denisovans is one of the most exciting findings in human evolution in the past decade. The striking similarity between sequences of the high-altitude adaptation gene EPAS1 in modern Tibetans and Denisovans suggested adaptive introgression. However, the time and geographic ranges where the adaptive introgression happened remain unknown. This talk consists of three studies that are related to archaic adaptive introgression. First, I show that modern Tibetans experienced two pulses of Denisovan introgression, among which a group more alike the Denisovans from the Altai mountains introduced the adaptive EPAS1 haplotype, and the positive selection on EPAS1 did not start until well-after the Last Glacial Maximum. Second, resolving the timeline of Denisovan adaptive introgression spurred an opportunity to reexamine Tibetan population history, which remains perplexing after decades of work. By leveraging genetic and archaeological evidence, I show that there are two possible models for the population history on Tibetan Plateau.

Our weekly seminar series featuring internal and external speakers in the field of ecology and evolutionary biology. This seminar will be in-person and livestreaming on Zoom (link this page).

Abstract:
The fundamental goal of the field of population genetics is to understand the evolutionary processes that govern allele frequency change. However, the actual mechanisms causing these changes - variation in individual survival, reproductive success, and movement - are often difficult to directly measure in natural populations. Fully understanding these processes requires the population pedigree, the set of relationships among all individuals in the population through time. Here, we elucidate the relative roles of different evolutionary processes in shaping patterns of genetic variation through time using a 25-year genomic, phenotypic, and pedigree dataset in the Florida Scrub-Jay (Aphelocoma coerulescens). Using gene dropping simulations, we estimated individual long-term genetic contributions and show how they are linked to measures of individual fitness and predictions of allele frequency change. Our approach allows us to quantify the expected genetic contribution of recent immigrants and identify large allele frequency shifts due to gene flow or selection. We modeled the relative roles of different evolutionary processes in shaping patterns of genetic variation genome-wide. Finally, we modified existing selection component analysis frameworks to test for selection acting on specific life-cycle stages. We identified a number of loci that clearly exhibited male gametic selection, sexual selection, and viability selection. By combining pedigree-based models with fine-scale dissection of selection components, this work provides a one of the most complete characterizations of the roles of selection, gene flow, and drift in governing allele frequency dynamics in a natural population to date.
