SUMMARY:Other:Leaves Under the Lens
DESCRIPTION:The leaf surface is a dynamic landscape where tiny\, specialized structures help plants interact with the world around them. Let’s bring this world into view! Join us for an exhibit that highlights the complex and often beautiful anatomy of leaves from the Matthaei collection. Plants throughout the conservatory will be paired with microscope photographs and micro-CT scans that illustrate the otherwise invisible structures that protect leaves from chewing insects\, absorb (or repel!) water\, and even recruit “bodyguards”. You won’t look at leaves the same way again! \n\nThis project is a collaboration between MBGNA and the Weber and Vasconcelos labs in the Department of Ecology and Evolutionary Biology\, led by PhD student Rosemary Glos.

SUMMARY:Presentation:EEB Student Dissertation Defense: Causes and consequences of disease outbreaks in aquatic environments
DESCRIPTION:Libby Davenport\, EEB PhD student\, presents their dissertation defense.\n\nAbstract: Disease outbreaks of environmentally transmitted parasites require that susceptible hosts encounter infective transmission stages (spores) distributed within environmental reservoirs and become infected. However\, we have limited empirical data about how changes in parasite environmental spore abundance influence disease dynamics. This is concerning because many environmentally transmitted parasites (e.g.\, chronic wasting disease\, white-nose syndrome\, anthrax\, etc.) pose major threats to human\, livestock\, and wildlife health. Moreover\, factors such as resource availability may affect the infection probability of a parasite during an encounter with a host as well as impacts of that parasite on exposed or infected hosts. Chronic sublethal impacts of parasites on host traits related to gut function may have consequences that scale up to affect ecosystem processes\, such as primary productivity and biogeochemical cycling\, although these potential impacts of parasitism remain relatively unexplored. My dissertation combines a multi-faceted six-month field study with a series of laboratory experiments to address the following questions: How does parasite spore abundance in the environment change over time and space? What is the relationship between disease outbreaks and spore abundance in the environment? How does resource availability affect infection success and impacts of a microsporidian parasite on its dominant grazer host?\nIn my dissertation research\, I used the freshwater invertebrate host Daphnia dentifera and five of its naturally occurring environmentally transmitted parasites to answer these questions. During my six-month field study\, I quantified spore abundance of the five parasites at every meter of the water column in the deep basin of six lakes in southeastern Michigan every two weeks using a digital PCR assay that I designed. Field-collected spore abundance data revealed that environmental spore abundance changed by several orders of magnitude over time and space and that lake basin shape and the strength of seasonal thermal stratification affected the evenness of spore distributions\, altering host-parasite encounter rates. When examining the relationship between environmental spore concentration and disease outbreaks\, I found significant time lags between the peaks in environmental spore concentration and infection prevalence\, which may have been influenced by parasite traits.\nIn my laboratory experiments\, I found that a microsporidian parasite was more likely to infect hosts when resources were abundant and this parasite significantly reduced grazing rates of infected hosts (although this impact was present at different times depending on resource availability). Thus\, the parasite-induced reduction in grazing rate could have broad impacts on lake food webs since the host is a dominant grazer\; these results set the stage for further investigation of how and when effects of parasitism scale up to influence higher-order ecological phenomena.\nOverall\, my dissertation contains one of the most comprehensive field studies examining the dynamic relationship between disease outbreaks and spore abundance in the environment and identifies resource-dependent impacts of a parasite on host density and traits that may have broader ecological consequences.\n\nThis is a hybrid event. \nTo join via Zoom: https://umich.zoom.us/j/94783248528\nPasscode: daphnia

SUMMARY:Workshop / Seminar:EEB Student Dissertation Defense // From Museums to Islands: How Species Interactions Affect Cryptic Traits
DESCRIPTION:Hayley Crowell\, EEB PhD student\, presents their dissertation defense.\n\nSummary: Our understanding of ecology and evolution depends on organismal traits we can detect and quantify. Hidden (i.e.\, cryptic) traits\, those not readily apparent or those obscured by variation in other traits\, represent a challenge in that they can lead to incomplete or incorrect interpretations of pattern and process in phenotypic evolution. The study of ecological and evolutionary interactions among species is particularly sensitive to these challenges in trait detection and quantification because every organism uses other species to survive and reproduce. If organisms are using hidden traits to communicate and function\, then we may be missing entire axes of variation crucial to our understanding of species interactions. Given that many organisms have vastly different sensory capabilities than humans\, studying cryptic traits in the context of species interactions provides the opportunity to examine animal behavior and ecology from perspectives more relevant to the interacting species themselves. My dissertation combines museum methods\, classroom experiences\, phylogenetic comparative analyses\, and field observations to investigate species interactions and their consequential effects on cryptic trait variation. This research provides a detailed exploration into the evolution of UV color in response to ecological variables\, as well as integrative ways to use museums and teaching to further our understanding of broader trait evolution in response to species interactions.\n\nThis is a hybrid event.

SUMMARY:Workshop / Seminar:EEB Student Dissertation Defense - Standing armies and crystal swords: Defense evolution across wild grape
DESCRIPTION:Carolyn Graham\, EEB PhD student\, presents their dissertation defense.\n\nSummary: The diversity of adaptations that plants demonstrate to defend themselves from herbivory has fascinated biologists for decades. To explain this wealth of defense traits\, researchers have developed a body of theory that uses patterns of ecological pressures in the environment to predict investment in defense\, but the importance of biological and geographic scale in determining which selective pressures dominate is only beginning to be tested. In this dissertation\, I explore the patterns and processes of defense trait evolution in plants\, examining whether defense investment across scales matches up with plant defense theory. Using the wild grape genus Vitis as my primary study system\, I synthesize comparative trait and occurrence data with mechanistic investigations of the processes that shape trait investment. In my first two chapters\, I use a phylogenetic framework to compare and contrast how patterns of trait evolution match up to plant defense theory depending on whether they are evaluated at the intraspecific or interspecific scale\, while considering a large body of traits associated with defense. I found that trait-trait correlations are rare across Vitis species compared to trait-environment correlations\, but that both types of interactions are scale-dependent. These results suggest that defenses in grape largely evolve independent of each other\, but that features of the environment thought to correlate with herbivory pressure are relatively better predictors of defense trait evolution. My third and fourth chapters center on calcium oxalate crystals in plant leaves\, an understudied trait that I use as a model to understand the mechanisms of plant defense evolution. As long as we have known about calcium oxalate crystal presence in plants\, researchers have believed that these structures are defensive against herbivory\, but recent literature has challenged that assumption. Through a systematic literature survey\, I find that crystal morphologies correlate differentially with geographic parameters\, suggesting that this morphological variation evolved in response to different ecological pressures. Additionally\, through experimental diet manipulations using a generalist herbivore\, I find that Vitis riparia-derived crystals do not operate as a defense against chewing arthropods\, but do seem to serve as a dynamic storage system for calcium in grape. By linking phylogenetic comparative and experimental approaches in tests of theory\, my dissertation provides us with a broader understanding of plant defense evolution in wild grape and beyond.\n\nThis is a hybrid event. \nJoin remotely: Join Remotely: https://umich.zoom.us/j/94285293918\nMeeting ID: 942 8529 3918\nPasscode: tuesem

SUMMARY:Workshop / Seminar:EEB Thesis Defense: Differences in morphological traits associated with thermoregulation in two howler monkey species and their hybrids
DESCRIPTION:Defense title: \"Differences in morphological traits associated with thermoregulation in two howler monkey species and their hybrids\"\n\nAbstract: \"Primates\, as endotherms\, regulate their body temperature regardless of external conditions\, driving the evolution of phenotypic traits to adapt to climate variation. Morphological traits often follow Bergmann's and Allen's rules\, in which species adapted to colder climates tend to have larger body sizes (Bergmann's) and smaller limb-to-body ratios (LBR) (Allen's rule) to retain heat. However\, neotropical primate research on thermoregulation has focused on behavioral strategies\, overlooking morphological adaptations. I examined Bergmann's and Allen's rules in Alouatta pigra and A. palliata\, sister species that diverged ~3 MYA. Given A. pigra's evolutionary history\, and its thicker pelage and presence in higher altitudes than A. palliata\, I expected A. pigra to have larger body sizes and smaller LBR than A. palliata. I then extended my analysis to backcrossed hybrids of the two species to assess the influence of admixture on body size and LBR in a warmer hybrid zone. My results were consistent with Bergmann's and Allen's rule. Understanding primate thermoregulation is crucial for conservation\, as it sheds light on their capacity to adapt to changing environments.\"\n\nPoster photo credits: Milagros González\n\nThis is a hybrid event. \nTo join remotely: \nZoom link: https://umich.zoom.us/j/98320971369\nMeeting ID: 983 2097 1369\nPasscode: howler

SUMMARY:Workshop / Seminar:EEB Prelim Seminar Series - Understanding the flourish of the species-rich\, but overwhelmingly homogeneous Neotropical myrtles
DESCRIPTION:Title: Understanding the flourish of the species-rich\, but overwhelmingly homogeneous Neotropical myrtles\n\nAbstract:\nNeotropical ecosystems harbour immense biodiversity as a result of a series of historical\, climatic and geological factors. Neotropical plant lineages have traced diverse evolutionary histories\, ranging from species and ecologically poor lineages to adaptive radiations. While morphologically and ecologically diverse clades have been extensively used to understand Neotropical plant diversification in space over time\, lineages expressing little morphological disparity have been generally understudied. My research will focus on Neotropical myrtles (Myrtaceae)\, which have been a source of challenge to many field biologists\, herbarium botanists and horticulturists for centuries for being both species-rich and morphologically homogeneous. I will employ phylogenetic comparative methods and experiments to investigate the adaptive value of structures in the seemingly ‘monotonous’ myrtle flower\, testing the hypothesis of predator-induced fusion of the calyx. Using a newly produced molecular phylogeny\, I will investigate trait divergence and biogeography in early stages of species diversification using a sister-species approach\, as well as mechanisms of co-existence where species show high levels of sympatry.\n\nThis is a hybrid event. \nJoin remotely: \nhttps://umich.zoom.us/j/99622972222\nMeeting ID: 996 2297 2222\nPasscode: 490332

SUMMARY:Workshop / Seminar:EEB Thursday Seminar Series - There and back again: Philopatry\, global change\, and the evolution of seasonal migration
DESCRIPTION:Seminar summary: Bird migration is one of our world’s most celebrated natural wonders. But how and why has migration evolved\, and what influence does it have on the ecology and evolution of migratory species? Ben will discuss research that his lab has been conducting on the evolutionary dynamics of bird migration. This work highlights seasonal migration as an adaptive strategy for site fidelity\, challenging traditional views of migration as a dispersal strategy for exploring new territories. The work further reveals migratory distance as a fundamental axis of the slow-fast continuum of life history that predicts the balance of survival and reproduction\, and leads to enhanced demographic stability and genetic diversity over evolutionary timescales.

SUMMARY:Workshop / Seminar:EEB Student Dissertation Defense - The role of dominant plants\, insects\, and climate in shaping communities and ecosystems
DESCRIPTION:Dissertation abstract: \nPlant communities are structured by multiple potentially interacting factors\, including interactions between plant species\, herbivores\, and climate. Critically\, the independent and potentially interactive effects of plant-plant interactions\, insect herbivory\, and precipitation on plant community structure and ecosystem function are rarely investigated. My dissertation addresses this research gap through a set of three separate field studies in old fields across Michigan. First\, I investigated the role of a dominant plant species in shaping plant species richness\, productivity\, and the community structure of associated arthropods. Specifically\, I found that the dominant plant species Solidago canadensis (Canada goldenrod) indirectly reduced arthropod abundance by reducing the biomass of all of the other plant species in the community\, in part by reducing light availability. With this work\, I demonstrate that the effects of a dominant plant on communities spans across multiple trophic levels. Next\, at the same field site\, I implemented a field experiment to study the independent and combined effects of S. canadensis and insects on plant diversity\, biomass\, subdominant species abundance\, microclimate\, plant functional traits\, and decomposition. Insect presence mediated the effect of S. canadensis removal on plant biomass and richness. Furthermore\, the effects of S. canadensis and insects extended belowground and determined the temporal variability of plant biomass. Overall\, these results emphasize the importance of considering the effect of insects when trying to understand the role of dominant plants in structuring plant communities and shaping ecosystem function above- and below-ground\, as well as overtime. Finally\, I examined the combined effects of a generalist insect herbivore and altered precipitation on plant biomass\, richness\, functional diversity\, and the community averaged trends of a suite of plant traits. Altered summer precipitation and the presence of the generalist insect Melanoplus femurrubrum (Red-legged grasshopper) had interactive effects on the plant biomass and on community averaged plant traits\, in particular. These results suggest that the traits of the most common species in the community are the most sensitive to altered precipitation and grasshopper herbivory. Taken together\, my dissertation comprehensively examines the factors that structure plant communities\, and in particular enhances our understanding of the interactive effects of dominant plants\, insects\, and climate on communities and ecosystems.\n\nThis is a hybrid event.

SUMMARY:Workshop / Seminar:EEB Student Dissertation Defense - Microbial Diversity and Dynamics in Lake Food Webs: Species Interactions\, Life History Strategies\, and Community Reassembly
DESCRIPTION:Dissertation Abstract: \nUnderstanding the processes involved in biodiversity maintenance and species coexistence is a central goal of community ecology. Lakes have long served as focal systems for exploring this puzzle\, as they harbor high microbial diversity despite their relatively stable and homogeneous appearance—a paradox that challenges classical formulations in ecological theory. A significant body of work suggests that steady states are exceptions rather than the norm in natural lakes. This dissertation engages with this theme by investigating microbial community diversity and dynamics in the context of cross-scale species interactions\, microbial life-history strategies\, and ecological memory. Together\, the chapters explore how general ecological principles play out in particular contexts—especially under heterogeneous environmental conditions and shifts in food web structures.\n\nThis is a hybrid event. \nJoin remotely: https://umich.zoom.us/j/99854884233\nMeeting ID: 998 5488 4233\n \nIn Chapter 2\, I examine the direct impacts of predation by introduced Dreissenid mussels on bacterial abundance\, diversity\, and composition in two regions of the Laurentian Great Lakes—Lake Erie’s western basin and Saginaw Bay in Lake Huron. While these mussels are known to exert strong top-down controls in lakes\, including microbial communities\, through filter-feeding\, I find their impacts to be variable. In some cases\, mussels significantly reduced microbial diversity\; in others\, their impacts were minimal or absent. Moreover\, I find that resistance to predation was structured at a shallower phylogenetic depth than previously reported in the low-nutrient Lake Michigan. These results highlight the role of context dependency and natural history in shaping animal-microbe interactions beyond host-microbiome systems.\n\nChapter 3 explores whether the observed shifts in microbial community structure and diversity can be explained through growth-defense theory. This canonical theory in ecology assumes that organisms face fundamental trade-offs due to differences in allocation strategies under resource-limited conditions. Using metagenomic methods\, I compare microbial populations resistant to mussel predation with those that are susceptible. I find no evidence for the emergence of resistance at the cost of growth. Instead\, resistance emerges as a complex trait\, shaped by varying patterns across phylogenetic\, molecular\, and broad functional levels. These results suggest that heterogenous environmental conditions in natural lakes may relax trade-off constraints in bacterial trait evolution\, as trade-off frameworks often rely on a priori assumptions about the tendency of ecosystems to move toward steady-state conditions.\n\nChapter 4 turns toward ecological memory. Using a common garden mesocosm setup\, which controls for the environmental differences between treatments by exposing them to the same background\, I test whether the historical presence of mussels alters microbial community reassembly following environmental perturbation. I sampled six temperate lakes from southeast Michigan\, three lakes with a history of mussel presence and three without. Microbial communities from lakes with and without mussels followed distinct reassembly trajectories. Moreover\, shifts in community structure translated into shifts in function\, indicating that the ecological memory of food web interactions leaves historical imprints with implications for broader ecosystem functioning.\n\nAcross chapters\, my findings raise questions about the universality of equilibrium-based theories in ecology. These studies show that microbial diversity emerges from the dynamic interplay between context-dependency\, functional traits\, and historical imprints of species interactions. While grounded in experimental and genomic methods\, this dissertation also critically engages with some foundational concepts in ecological theory (Chapters 1 and 5). In doing so\, it gestures toward a broader philosophical tension in ecological thought: the inherent complexity of biodiversity and the challenges associated with its abstraction (Chapter 6).

SUMMARY:Workshop / Seminar:EEB Tuesday Seminar Series - Seasonal migration as a driver of life history trade-offs and genetic diversity in Nearctic-Neotropical passerines
DESCRIPTION:Evolutionary trade-offs between fecundity and survival are ubiquitous in evolution. In high-latitude seasonal environments\, most birds breed during resource-rich summers\, and migrate to lower-latitude environments during the winter to survive. However\, the trade-off between fecundity and survival appears to scale with migration distance: By migrating farther\, birds may gain higher survival benefits\, but in doing so\, they sacrifice time that they might have spent raising offspring. Longer migrations are thus associated with \"slower\" life histories (higher survival\, fewer offspring)\, but this apparently straightforward trade-off belies an intriguing underlying paradox: Slower life histories are typically associated with lower genetic diversity\, but in migratory birds\, there is evidence that longer migrations are positively correlated with genetic diversity\, possibly because they promote demographic stability. Nevertheless\, populations of long-distance migrants readily switch strategies\, implying that populations will move quickly toward new optima if migration’s survival benefits no longer outweigh its reproductive costs\, with unknown population genetic consequences. My dissertation will combine movement ecology and population genetics to assess the ways in which seasonal migration has mediated life history trade-offs and impacted genetic diversity within species\, with the goal of understanding how the risks of migration have translated to rewards over evolutionary timescales.

SUMMARY:Workshop / Seminar:EEB Student Thesis Defense - The Effects of Pteridium aquilinum (Bracken fern) on Understory Microclimate and Seedling Success in Temperate Forests
DESCRIPTION:Title: The Effects of Pteridium aquilinum (Bracken fern) on Understory Microclimate and Seedling Success in Temperate Forests\n\nAbstract: The understory influences biodiversity and ecological processes and are a defining element of forest ecosystems\, as they can contain up to 90% of plant species in temperate forests. Bracken Fern (Pteridium aquilinum) often dominates forest understory communities globally\, including those in Northern Michigan. Dominant understory species affect ecosystems proportional to their high abundance. To explore how bracken fern impacts microclimate\, plant diversity\, and seedling success\, I asked two overarching questions: (1) how does natural variation in density of a dominant species impact understory abiotic conditions and plant diversity? (2) How does the cover and removal of a dominant species affect seedling survival and success? I established a bracken fern removal experiment in three forests at the University of Michigan Biological Station (UMBS). I paired plots where the bracken fern cover was left intact (natural) with plots where the bracken fern cover was removed (removal)\, across a gradient of bracken fern densities (0\, 25\, 50\, 75 100% cover). Soil moisture and temperature varied across the gradient of bracken fern density in natural plots. At peak growing season\, soil moisture variation was the highest in 50% natural plots. We did not detect a significant difference in seedling survival across the gradient of bracken fern density in either natural or removal plots. Seedling leaf area\, specific leaf area\, and leaf carbon-to-nitrogen ratios were not significantly affected by the removals. In 75% natural plots exclusively\, removal had a negative effect on seedling green leaf % N. Our results highlight that dominant understory species differentially influence understory microclimate and seedling traits in temperate forests\, but their impact is not proportional to cover. Instead\, bracken fern cover may be both facilitative and inhibitory for seedling growth and establishment\, showcasing the dynamic role of dominant species in temperate forests.\n\nThis is a hybrid event. \nJoin remotely: https://umich.zoom.us/j/93842698134\nMeeting ID: 938 4269 8134

SUMMARY:Workshop / Seminar:EEB Student Dissertation Defense: Above- and Belowground Functional Trait Variation and Its Effect on Tree Seedling Response to Environmental Change
DESCRIPTION:Dissertation Title: Above- and Belowground Functional Trait Variation and Its Effect on Tree Seedling Response to Environmental Change\n\nAbstract: To predict forest composition and function under global change it is important to understand tree responses to environmental shifts. This is especially true for seedlings\, as the seedling stage represents an important forest recruitment bottleneck. Therefore\, understanding the capability of seedlings of different tree species to respond to environmental changes will provide insight into how forests may look in the future. Tree responses depend on their ecological strategies\, which can be defined by the functional traits of their leaves and roots\, organs responsible for resource uptake above- and belowground. Prior work at the interspecific scale suggests that traits separate into three independent axes: above- and belowground resource conservation axes describing plants resource uptake efficiency and investment in organ construction\, and a belowground collaboration axis describing the degree to which plants rely on mycorrhizal fungi – key root symbionts that aid in resource capture belowground. However\, no work to date has explicitly tested if the proposed collaboration axis accurately describes how plants associate with mycorrhizal fungi\, and therefore the extent to which roots and their symbionts contribute to nutrient uptake within species remains largely untested. My dissertation addresses this through four chapters that systematically examine patterns of plant functional trait variation and their implications for seedlings success.\n\nIn Chapter 1\, I outline the current understanding of the relationships between roots and mycorrhizal fungi in trees\, proposing that because roots and mycorrhizal fungi operate together\, we should examine both simultaneously to get a thorough understanding of resource acquisition strategies belowground. In Chapter 2\, I examined whether the collaboration axis exists independently of the two resource conservation axes intraspecifically within seedlings of Quercus rubra\, Acer rubrum\, A. saccharum\, and P. serotina collected across Michigan. I found that aboveground traits are independent of belowground traits\, however belowground traits aligned on a single axis\, further calling into question the functionality of the collaboration axis.\n\nIn Chapter 3\, I examined the degree to which plant functional traits of tree seedlings vary with communities of mycorrhizal fungi across a nitrogen (N) gradient. Changes in N impact the function of plants and mycorrhizal fungi alike\, though no study to date has examined both simultaneously. I collected seedlings of two different mycorrhizal types: Q. rubra (ectomycorrhizal\; EcM)\, and A. rubrum and P. serotina (arbuscular mycorrhizal\; AM). Some EcM fungi can provide access to organic N that is otherwise inaccessible to plants\, providing an advantage at low N. I found that seedlings tended to be more acquisitive belowground at higher N\, EcM access to organic N decreased with N\, and that traits not included in the collaboration axis change with mycorrhizal function\, suggesting that the proposed collaboration axis is insufficient to describe plant reliance on mycorrhizae.\n\nIn Chapter 4\, I applied the trait patterns observed within species in prior chapters to see how variation in traits affects seedling growth under multiple environmental stresses. Prior work examined responses of plants to a single stress\; yet stresses rarely occur alone. I grew seedlings of Q. rubra\, A. rubrum\, and A. saccharum in the greenhouse under three levels of water and light\, measuring their growth and functional traits. I found that growth decreased under multiple stresses less than is expected based upon the reduction in growth experienced when exposed to singular stresses. Furthermore\, different species had different trait strategies to cope with multiple stressors.

SUMMARY:Workshop / Seminar:EEB Prelim Seminar Series - The purr-suit of reproduction: connecting microbiomes and reproductive health in Felids
DESCRIPTION:Summary: The communities of microbes that inhabit the gut and reproductive tract\, known as the gut and reproductive microbiomes\, show a symbiotic relationship that influences host physiology and reproductive outcomes. This can be seen in the gut microbiome’s influence on nutrient acquisition\, the production of biologically active molecules\, and the modification of steroid hormones\, as well as in reproductive microbiomes’ impacts on sperm quality\, assisted reproductive technology success\, embryo quality\, susceptibility to STIs\, and offspring health. While the majority of research into these topics is in humans\, mice\, and livestock\, investigations into wildlife species have also revealed similar patterns. However\, further research is still needed across a broader range of taxa\, particularly in species with low reproductive success that depend on consistent reproduction to be self-sustaining. Ex situ populations of cheetahs (Acinonyx jubatus) and clouded leopards (Neofelis nebulosa) that are part of American Association of Zoos and Aquariums Species Survival Plans (AZA SSP)\, are two such populations that have poor reproduction and rely on conservation husbandry for population health and survival. Therefore\, the main goal of my dissertation is to investigate the relationship between the gut\, vaginal\, preputial\, and seminal microbiomes and reproductive phenotypes and physiology in these two threatened species\, along with their model species\, the domestic cat (Felis catus)\, in order to extend the applicability of this research to other threatened felids.

SUMMARY:Workshop / Seminar:EEB Prelim Seminar Series - A Feeling for the Organism: Understanding Trait Evolution in Polypore Mushrooms
DESCRIPTION:Talk Title:  A Feeling for the Organism: Understanding Trait Evolution in Polypore Mushrooms\n\nSummary: My project proposal broadly investigates macrofungal evolution through a specific focus on sporocarp traits. For this\, I use two different species of wood-inhabiting fungi that produce fruiting bodies having a poroid hymenophore (porous spore producing layer on the underside of the mushroom)\, commonly referred to as polypores. Polypores\, which form a polyphyletic group within Basidiomycota\, are unique in harboring species that produce annual and perennial hardy\, poroid fruiting bodies which can remain exposed to the external environment and maintain functionality for long periods of time. Unlike the fruiting bodies of a majority of macrofungal species\, given the persistence of certain polypore fruiting bodies on their wood-substrate over extended time periods\, species within Polyporaceae are suitable for investigating the evolution of life history traits and adaptation in macrofungi. My PhD project will focus on two established traits- colour polymorphism and longevity\; and will further use population genetics to identify traits that may be important for local adaptation. The first two chapters will be focussing on Trametes versicolor (aka Turkey Tail) which is a highly colour polymorphic\, globally distributed\, hardwood decay fungus found growing on a wide range of hardwood species. Using T. versicolor\, I firstly aim to uncover if colour polymorphism in the species is linked to the wood species it grows on or if it is a heritable trait\; and secondly\, aim to determine whether it has population structuring across its geographic distribution\, and local adaptation to each habitat of occurrence. In my third chapter\, I propose to use Ganoderma applanatum (aka Artist’s conk) which has a perennial fruiting body that remains functional and fertile for several years to investigate senescence and the evolution of this alternate life history strategy.

SUMMARY:Workshop / Seminar:EEB Prelim Seminar Series -  Life in Plastic\, It’s Fantastic: The microbial metabolisms of polyethylene and the implications for social phenotypes
DESCRIPTION:Talk title: Life in Plastic\, It’s Fantastic: The microbial metabolisms of polyethylene and the implications for social phenotypes\n\nSummary: Microbes are responsible for breaking down recalcitrant organic matter like lignin and chitin and thus reintroducing those molecules back into nutrient cycles. To do so\, these microbes invest lots of energy into creating powerful arsenals of enzymes. These microbes are now challenged globally with novel recalcitrant polymers known collectively as plastic. Studies have found that there is little to no correlation of plastic degrading enzymes and the amount of plastic in the environment- leading to the conclusion that in general\, microbes are not evolving to specialize on plastic degradation. However there is yet to be a satisfactory explanation as to why environmental degradation is so limited.\n\nWhile many microbial enzymes have been tested or hypothesized to degrade plastic\, research on plastic biodegradation has primarily focused on one species at a time\, and very few have been proven to work with polyethylene\, the most widely used and hardest to degrade plastic. My dissertation will focus on characterizing microbial metabolisms of PE and its degradation products\, and using these characteristics to predict the ecological relationship between members of a small modular community. This research will connect microbial metabolisms and ecology to investigate why environmental degradation is limited\, and how metabolisms impact the function of plastic degrading synthetic consortia.

SUMMARY:Workshop / Seminar:EEB Prelim Seminar Series - How do functional and life history traits mediate bee-plant interactions and distributions?
DESCRIPTION:Summary: Bees (Hymenoptera : Apoidea : Anthophila) are a speciose and functionally diverse clade of insects\, comprising over 20\,000 described species which act as key pollinators across terrestrial and agricultural ecosystems. However\, despite their ecological and economic importance\, we still lack fundamental understanding of the consequences of bee functional and life history variation for bee ecology\, evolution\, and pollination services. As native pollinator abundance and diversity continue to decline worldwide\, expanding our understanding of how trait variation among bees shapes their geographic distributions and dietary preferences will enhance our ability to predict how global changes may impact this crucial ecosystem service. In this dissertation\, I seek to address these gaps by adopting a macroecological and macroevolutionary approach to bee trait diversity. I will integrate large datasets of traits and phylogenies to identify the environmental factors that govern variation in key functional traits and explore how this variation influences bees' interactions with flowering plants. I will also generate new data on diet preferences for poorly studied tropical bees using novel approaches for honey and pollen metabarcoding and contribute to ongoing efforts in the field to create large\, global datasets of bee traits and bee-plant interactions. Ultimately\, this research will provide new insights into the ecological processes shaping bee diversity and their interactions with flowering plants.

SUMMARY:Workshop / Seminar:EEB Student Dissertation Defense - Selections in molecular and phenotypic evolution
DESCRIPTION:Dissertation Title: Selections in molecular and phenotypic evolution\n\nDissertation Abstract: Selection plays an undoubtedly important role in evolution. My dissertation explores the pattern and impact of selection at both molecular and phenotypic levels. In Chapter 1\, I challenged the neutral theory of molecular evolution by demonstrating that beneficial mutations are way more abundant than previously assumed. I proposed an adaptive tracking theory to reconcile this finding with the low substitution rate inferred from comparative genomic patterns\; under this theory\, a natural population is always adapting to the rapidly changing environment. In Chapter 2\, I investigated the genetic maintenance of human same-sex sexual behavior (SSB) and showed that modern contraception had disrupted previously hypothesized evolutionary mechanisms that maintained SSB-associated alleles. In Chapter 3\, I further distinguished between bisexual behavior (BSB) and exclusive SSB (eSSB) in their genetic basis\, finding that BSB-associated alleles may confer reproductive advantages whereas eSSB-associated alleles are likely under negative selection. In Chapter 4\, I examined the genetic architecture of the human sex ratio\, identified the impact of large measurement error in inferring the heritability of sex ratio\, and provided genomic evidence supporting Fisher’s principle. Finally\, I addressed methodological aspects of evolutionary analysis: in Chapter 5\, I uncovered biases in inferring fitness landscape ruggedness due to measurement errors and proposed a correction\; in Chapter 6\, I introduced “effective fitness” as a more informative metric to quantify fluctuating selection with genetic drift. Collectively\, these findings underscore the pervasive role of natural selection in both molecular and phenotypic evolution and offer new frameworks for understanding

SUMMARY:Workshop / Seminar:EEB Student Thesis Defense -  Getting deep: A spatiotemporal dive into vertical phytoplankton patchiness in Michigan lakes
DESCRIPTION:Abstract: Seasonal succession of phytoplankton distribution and community composition are well-established in aquatic ecology. However\, localized peaks in phytoplankton abundance—patchiness—can deviate from expected trends. To better understand this variability\, I analyzed vertical profiles of phytoplankton distribution across fifteen lakes in southeast Michigan over three field seasons (2021-2023). I focused on four major phytoplankton groups—green algae\, cyanobacteria\, diatoms\, and cryptophytes—and examined how their abundance varied with depth\, temperature\, and season. Detailed case studies from six representative lakes highlight how basin morphometry influences thermal stratification\, shaping phytoplankton patchiness and concentration over time. Green algae were typically most abundant at the surface during summer months\, though several lakes exhibited benthic green algal peaks. Cyanobacteria\, diatoms\, and cryptophytes showed greater variability across depth and lakes\, with cryptophytes often displaying more consistent abundance throughout the water column. Temperature profiles followed expected seasonal trends\, with strong stratification in summer and mixing in the fall. These results emphasize the importance of considering lake-specific conditions in driving vertical phytoplankton patchiness.

SUMMARY:Workshop / Seminar:EEB Prelim Seminar Series - Variation and Plasticity: Investigating the evolutionary history of migratory variation and seasonal phenotypic plasticity in the butterfly genus Danaus
DESCRIPTION:Seminar Preview: The annual migration of the monarch butterfly spans over 4\,000 km and facilitates the aggregation of millions of individual butterflies in south-central Mexico each winter. The monarch migratory syndrome is complex\, integrating behavior\, morphology\, and physiology in an environmentally sensitive manner. Underlying this syndrome is an expansive genetic suite encompassing over 500 genes\, as well as a significant capacity for seasonally-sensitive phenotypic plasticity. The evolutionary histories of this genetic suite and capacity for seasonal plasticity remain largely unknown beyond within-monarch assessments.\nMonarch migration is an emerging model for testing broader hypotheses about the evolution of animal migration\, complex traits\, and the role of plasticity in adaptive evolution. A clearer understanding of how this spectacular phenomenon has emerged within just the past 20\,000 years is necessary to better contextualize evolutionary inferences drawn from this model. My dissertation research will focus on characterizing patterns of seasonal plasticity as well as migratory genetic and phenotypic variation within the butterfly genus Danaus. This work integrates comparative approaches in phylogenomics and developmental genetics to generate insights into how key features of the monarch migratory syndrome have evolved within the genus.

SUMMARY:Workshop / Seminar:EEB Student Dissertation Defense - How fish and fisher behavior affect production in small-scale reef fisheries
DESCRIPTION:Title: How fish and fisher behavior affect production in small-scale reef fisheries\n\nSummary: Reef fisheries\, which provide food and livelihoods for over one billion people\, are in decline due to growing population demands and climate-driven habitat loss. As the challenges facing these social-ecological systems intensify\, it is critical to understand the relationships between fishing communities and reef ecosystems. My dissertation draws on ecological and social science theory\, quantitative modeling\, field experiments\, and ethnographic research to provide an insight into the role of fish and fishers’ behavior in shaping small-scale reef fisheries. In my first study\, I documented behavioral responses of fishers in The Bahamas to a Category 5 hurricane and the COVID-19 pandemic\, highlighting key factors that influence resilience in the face of external shocks. In two subsequent studies\, I investigated the use of artificial reefs to augment fisheries production in the Caribbean. I used an individual-based model to demonstrate how fish behavior and size structure alter production dynamics on artificial reefs. Next\, I combined a decade of timeseries data on artificial reefs\, empirical data on fish population dynamics\, and production models to provide mechanistic evidence that artificial reefs enhance fisheries production. Together\, my research provides scientific insight into community resilience and fisheries management strategies that can be used to help support small-scale fisheries and the communities who depend on them.

SUMMARY:Workshop / Seminar:EEB Student Dissertation Defense - Seeds of Change: The Power of Small-Scale Farming Communities
DESCRIPTION:Abstract:  Alexa critically examines the role of farm size in sustainable agriculture within the context of global food systems and political economies. She argues that small-scale farms are vital for sustainable development due to their unique capacity to implement eco-friendly practices and maintain local food sovereignty\, contrasting significantly with large-scale\, corporate farming models. The research utilizes a mix of qualitative and quantitative methods to explore how different farm sizes affect agricultural sustainability across diverse geographies\, including detailed case studies in Jamaica and Hawaii. By integrating theoretical frameworks with empirical research\, this study contributes to the discourse on sustainable agriculture and challenges existing policies that favor large-scale operations over smaller\, more sustainable farming practices.

SUMMARY:Workshop / Seminar:EEB Prelim Seminar Series: Long-Distance Migration as a Driver of Cognitive Evolution
DESCRIPTION:About this seminar: Cognitive evolution shapes how animals respond to the demands of their environment. The phenomenon of long-distance migration may drive cognitive evolution: migrant animals must find food in unfamiliar environments\, whereas some non-migratory\, ie. resident animals benefit from stable habitats with consistent resources. It has been hypothesized that an increased sensory capacity for information collection may trade-off with memory retention\, but this hypothesis has limited empirical evidence. I aim to test this hypothesis using the monarch butterfly model. Their phenotypic diversity\, with distinct migratory and resident populations worldwide\, provide a unique opportunity to examine their cognitive differences. I will start by comparing sensory capacity and learning capabilities between migratory and resident monarch butterfly populations to assess how migration shapes cognitive evolution. I will then investigate the underlying mechanisms driving cognitive differences using multiple different comparative approaches across populations: brain plasticity\, sensory organ morphology\, and sensory gene-expression. Finally\, I will conduct comparative studies of foraging strategies in migratory and resident monarch populations\, focusing on explorative and exploitative differences\, as well as foraging site fidelity\, to infer how cognitive phenotypes shape decision-making in the wild.

SUMMARY:Workshop / Seminar:EEB Student Dissertation Defense - Comparing micro- and macroevolutionary diversification dynamics between Neotropical montane and lowland birds
DESCRIPTION:Abstract:\nThe tropical Andes mountains and adjacent Amazonian lowlands are home to more species than anywhere else in the world. Prior work suggests that avian species richness declines but speciation rates increase as elevation increases in this biodiversity hotspot. Tropical mountains are also characterized by steep elevational turnover in environmental conditions\, including the availability of oxygen. My thesis compares diversification and selection dynamics between lowland Amazonian and Andean montane species\, with a special emphasis on tanagers\, an iconic Neotropical radiation and the most speciose family of songbirds. I focus on how patterns and processes of the early stages of speciation vary across elevation in the Andes-Amazonia system\, and on the molecular evolutionary consequences of hypoxic stress at high altitudes.\nWhether large macroevolutionary biodiversity gradients emerge from underlying microevolutionary processes is an active area of research in evolutionary biology. For example\, elevational gradients in speciation rates could be caused by geographic variation in the tendency for populations to become isolated and diverged from one another. A major focus of my dissertation is evaluating whether Neotropical montane and lowland regions differentially promote incipient speciation\, linking microevolutionary processes to broader biodiversity patterns. First (Chapter 2)\, I aggregated previously published mitochondrial phylogeographic datasets from birds in the Andes-Amazonia system (~7\,000 sequences from 103 species)\, to test whether levels of intraspecific population structure vary across elevation and whether rates of population differentiation predict speciation rates. My results revealed that phylogeographic structuring is higher in montane birds and increases with elevation\, but rates of population differentiation did not predict speciation rates in the focal set of taxa.\nNext (Chapter 3)\, I more rigorously explored how Andean and Amazonian landscapes promote population isolation and differentiation using whole-genome comparative phylogeography in 8 species of Tangara tanagers (4 Andean and 4 Amazonian). My results show that Andean species consist of more differentiated\, less connected\, smaller\, and less genetically diverse populations than Amazonian species. This supports a scenario of greater incipient speciation in the mountains\, but these same characteristics also reduce persistence in a theoretical metapopulation framework. In conjunction with results from my previous chapter\, I suggest that there exists a tension between factors promoting divergence versus persistence\, which could contribute to observed elevational biodiversity gradients in Neotropical birds.\nFinally\, elevational gradients are also marked by increasing hypoxia at higher altitudes\, an important physiological stress owing to the essential role that oxygen plays in cellular energy production. In Chapter 4\, I use comparative genomic methods across 20 species of Neotropical tanagers to test whether signatures of selection in oxidative phosphorylation genes vary with elevation. I find evidence of stronger purifying selection on components of this metabolic pathway in species with higher elevational distributions\, expanding our understanding of how tropical montane species cope with reduced oxygen availability.

SUMMARY:Workshop / Seminar:EEB Student Dissertation Defense - Macroevolutionary patterns of a complex phenotype: Disparity\, convergence\, and integration of the Neotropical cichlid feeding system
DESCRIPTION:Abstract: Organisms consist of many anatomical systems that function together to form complex phenotypes\, which are involved in tasks such as feeding\, breathing\, or locomotion. These phenotypes require the coordinated evolution\, or coevolution\, of numerous traits to maintain functionality. However\, multifunctional phenotypes face trade-offs that may restrict their diversification. The skull of fishes represents a complex phenotype\, containing over 100 bones\, which perform multiple functions such as feeding\, breathing\, and brooding eggs. Neotropical cichlids represent a fruitful system to study how a complex phenotype\, the feeding system\, has evolved in the context of an ancient adaptive continental radiation\, with repeated transitions to specialized diets\, and a second jaw in their throat\, which is thought to have resulted in their immense ecological and species diversity across two continents through functional decoupling. This dissertation investigates the macroevolutionary patterns in cichlid feeding morphology to better understand how complex phenotypes\, which are multifunctional\, have evolved in the context of constraint and adaptation. Utilizing three-dimensional geometric morphometrics and microcomputed tomography (μCT) scanning\, I explore the diversity and macroevolutionary patterns of the Neotropical cichlid feeding system\, including all bones in the oral and pharyngeal jaw for the first time. \nIn Chapter 2\, I characterize the diversity and phylogenetic trajectories of pharyngeal jaws across Cichlinae. The upper pharyngeal jaw has been largely absent in studies of cichlid feeding\, however\, with µCT scanning\, I am able to describe the diversity of the upper pharyngeal jaw and measure disparity through time\, revealing unexpected patterns in phenotypic divergence. In Chapter 3\, I examine the relationship between diet and feeding morphology\, highlighting instances of morphological convergence and divergence among ecologically similar species. I also reconstruct the evolutionary history of dietary transitions and test for correlations between diet and previously unstudied morphological traits. Lastly\, I test the hypothesis that functional decoupling has led to evolutionary decoupling between the oral and pharyngeal jaws in Chapter 4. My findings challenge traditional views on functional decoupling and suggest that evolutionary integration between the two jaws is necessary for functional decoupling to occur. The findings from this dissertation enhance our understanding of how complex phenotypes have evolved at a continental scale\, and the influence diet has on shaping macroevolutionary patterns.

SUMMARY:Workshop / Seminar:EEB Student Dissertation Defense - The secret life of leaves in tree species’ life history strategies: patterns across tropical and temperate forests
DESCRIPTION:Dissertation abstract: We share our planet with hundreds of thousands of other species\, including more than 73\,000 tree species alone. Making sense of this tremendous amount of biodiversity has remained an on-going challenge\, and ecologists are often limited in our ability to study how species identities influence community dynamics and ecosystem processes at larger scales\, particularly in diverse tree communities such as tropical forests. The use of functional traits as indicators of species’ life history strategies and other key aspects of their performance has the potential to help us find general trends in biological communities. However\, the extent to which traits link to measures of species’ fitness for diverse species assemblages needs further development. Specifically\, leaf traits play key roles in photosynthetic pathways\, yet the functionality of leaf traits as indicators of tree species’ life history strategy remain ambiguous. This dissertation closely examines the role of leaves as indicators of tree species’ growth and mortality rates. I find that leaf traits play a greater role in characterizing how tree species’ growth responds to resource availability rather than their average or maximum growth rates\, and have significant indirect effects on species’ life history strategies that are not evident when we consider only direct effects. I also found evidence for a trade-off between species’ allocations to individual leaves versus to their crown\, which together uncovers a stronger role of leaves as indicators of species’ growth strategies\, and that trait patterns in temperate forests sometimes are sometimes opposite to those found in tropical forests. Together\, these results deepen our understanding of the role of leaves in tree species’ life history strategies and support our efforts to find general patterns in forests around the world.

SUMMARY:Workshop / Seminar:EEB Student Dissertation Defense - Computational Morphometrics of Half a Million Herbarium Specimens Reveals Lineage-Specific Evolutionary Dynamics in Climate-Leaf Trait Relationships
DESCRIPTION:Abstract:\n\nDigitized herbarium collections facilitate access to hundreds of millions of preserved plant specimens\, enabling quantitative analysis of leaf morphology across taxonomic and geographic scales. This dissertation presents a computational framework that leverages machine learning\, computer vision\, large‐language models\, and novel mathematical methods to extract\, analyze\, and interpret leaf traits at scale. By combining lineage‐specific approaches with broad comparative analyses\, it establishes procedures for measuring traits across these vast datasets.\nChapter 2 introduces LeafMachine2\, a modular machine‐learning 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‐landmarks such as midvein length\, petiole length\, and lobe positions. This tool processes thousands of images per hour\, calculates pixel‐to‐metric conversion factors for most common scalebar types\, and generates standardized measurements (area\, perimeter\, Fourier descriptors\, and landmark‐based 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‐scale analyses.\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‐readable 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‐to‐metric conversion\, decodes QR codes to assign meaningful file names\, and embeds GPS metadata. Validation tests across smartphone\, mirrorless\, and machine‐vision cameras demonstrate high accuracy in scale conversion and reliable QR code decoding at typical working distances. FieldPrism enables the creation of “snapshot vouchers” that complement physical voucher specimens\, opening new possibilities for citizen science and field‐based trait collection.\nChapter 4 explores the integration of large language models (LLMs) into herbarium label transcription. VoucherVision combines optical character recognition with LLM‐based 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‐tuned\, community‐driven LLM solutions that respect data ownership and ensure reproducibility.\nChapter 5 applies LeafMachine2\, Euler characteristic transform (ECT)\, and a novel geomorphon‐based 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–leaf trait associations—larger\, entire-margined leaves in warmer\, wetter environments and more toothed or lobed leaves in cooler\, drier locations—are clade-specific rather than universal across angiosperms. Instead\, family‐ and genus‐specific evolutionary regimes emerge. Phylogenetic correction often weakens climate-leaf area associations while strengthening leaf shape associations with minimum temperatures. Correlated‐trait analyses reveal that margin‐type evolution is climate‐dependent 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.\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.

SUMMARY:Workshop / Seminar:EEB Prelim Seminar Series - Microbial legacies: effects on community structure\, function\, and response dynamics
DESCRIPTION:Abstract:\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.

SUMMARY:Workshop / Seminar:EEB Student Dissertation Defense - Divergence in Gene Expression Plasticity
DESCRIPTION:Defense Preview:\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.

SUMMARY:Workshop / Seminar:EEB Thursday Seminar Series - Behavioral ecology at the ant-plant-herbivore interface: Ant-induced effects on herbivore decisions
DESCRIPTION:Foliage represents a major zone of biological interaction in terrestrial ecosystems. 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.

SUMMARY:Workshop / Seminar:EEB Friday Seminar Series - Ant-fruit/seed interactions in Neotropical ecosystems: Effects on the biology of seeds and seedlings
DESCRIPTION:Although most shrub and tree species in tropical environments are primarily vertebrate-dispersed\, interactions between ants and fallen fleshy diaspores are frequent. Our studies have focused on the services provided by ants to fallen fleshy diaspores of primarily vertebrate-dispersed trees in Brazilian Cerrado savanna and Atlantic rainforest. In this talk\, I report which ant species interact with fallen diaspores\, their contribution to seed removal\, and effects on seedling establishment and growth. Field studies by our group confirm the prevalence of interactions between ants and fallen fleshy diaspores\, revealing potential ant-derived benefits to seeds and seedlings in both biomes. Although seed dispersal distances by ants are shorter compared to birds\, our data show that fine-scale\, ant-induced seed movements may ultimately enhance plant regeneration at early developmental stages in Cerrado and Atlantic rainforest. Current human-induced fragmentation and defaunation of tropical environments suggests that short-distance dispersal by ants may become increasingly important in the dynamics of ecosystems\, since many vertebrate seed dispersers have been locally extirpated or are in decline.

SUMMARY:Workshop / Seminar:EEB Student Dissertation Defense - Recovering the missing links: from genomic signatures to virus-host interaction networks
DESCRIPTION:Abstract: \n\"In a little more than a century\, viruses have emerged from being invisible to human knowledge to being recognized as ubiquitous biological forces shaping microbial ecosystems worldwide. 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.\"

SUMMARY:Workshop / Seminar: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!)
DESCRIPTION:This week\, we have two speakers for our Tuesday seminar! \nPlease read details below: \n\n1) Dr. Anne Kort\, Michigan Society of Fellows Postdoctoral Scholar\n\nTitle: Uncovering the Early Evolution of Canids from an Exceptional Skeleton of Mesocyon\n\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.\n\n2)  Dr. Jill Myers\, biodiversity lab manager\n\nTitle: Reducing Plastic Waste in the Lab (Pt. 1!) \n\nDescription: Globally\, research labs generate more than 12 billion pounds of plastic waste per year. Single-use plastic pipette tips are one major source of this waste. In this short talk\, I will introduce our new pipette tip washing machine and share plans for its current and future use in EEB and the anticipated impacts.

SUMMARY:Workshop / Seminar:EEB Tuesday Seminar Series - Applying high-structure and study skills training to support students’ learning
DESCRIPTION:Description: Research has shown that active learning and high structure can reduce disparities in learning outcomes by 40-60% across STEM courses (Theobald et al. 2020). Follow-up research is currently focused on two questions: 1) why are active learning and high-structure so effective in helping underprepared students\, and 2) what additional interventions can close historical gaps even further? To achieve disproportionate benefits for underprepared students\, the heads-and-hearts hypothesis focuses on increased deliberate practice and supportive learning environments\, while the study-skills hypothesis emphasizes course designs based on learning objectives and advances in cognitive science. The literature shows that switching from traditional to evidence-based teaching leads to significantly higher student success.

SUMMARY:Workshop / Seminar:EEB Tuesday Seminar Series -  Dr. Yang Li and Jiachen Li
DESCRIPTION:We have two speakers on Sept. 23! See information below: \n\nSpeaker 1: Jiachen Li\, master's student\, Department of Computational Medicine & Bioinformatics\, Zhang Lab\n\nTitle: Chance and necessity in evolution: how repeatable is phenotypic evolution?\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—a 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.\n\n\nSpeaker 2: Dr. Yang Li\, EEB Postdoctoral Fellow\, Zhang Lab.\n\nTitle: Navigability of thousands of adaptive landscapes of RNA and protein expressions by trans-regulatory mutations\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.

SUMMARY:Workshop / Seminar:EEB Tuesday Seminar Series - Color\, Chemistry and Courtship: Exploring how pigmentation genes shape mating behavior in Drosophila
DESCRIPTION:Description:  Pleiotropy offers a unifying framework that reveals how seemingly unrelated traits can be linked through a single gene. One such group of genes in the class insecta are the pigmentation genes. My project will focus on understanding how tissue-specific regulation of pigmentation genes underlies variation in mating signals in Drosophila. Specifically\, I will investigate three interrelated themes: (1) how pigmentation genes influence mating behavior\, (2) the evolutionary consequences of pleiotropy across species and (3) the tissue-specific regulatory architecture that enables modular gene function. This project will identify which regulatory modules influence chemistry\, colour\, or both\, providing empirical evidence for how modularity mitigates pleiotropic constraints. Additionally\, comparative analysis in the D. americana group—where pigmentation and CHC divergence might contribute to incipient speciation —will place functional results in a macro-evolutionary context\, asking whether the same pleiotropic variants are repeatedly recruited or whether selection favours lineage-specific solutions.

SUMMARY:Workshop / Seminar:EEB Thursday Seminar Series - The rapid decline of butterfly abundance and diversity in the United States
DESCRIPTION:Seminar Summary - Over the past two decades\, the United States has lost a quarter of butterflies. This includes loss of common species like monarchs and cabbage whites\, and rare species on the verge of extinction. We know this from data accumulated by thousands of individuals\, and not only scientists\, who have done tens of thousands of surveys and recorded millions of butterflies. Solutions to reverse declines are in our grasp\, but need to be acted on now.

SUMMARY:Workshop / Seminar:EEB Thursday Seminar Series - Understanding the fitness effects of mutations and implications for small populations
DESCRIPTION:Seminar Summary - 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. Lastly\, I will discuss how insights gained from studying deleterious mutations may help identify small populations at risk of inbreeding depression.

SUMMARY:Workshop / Seminar:EEB Tuesday Seminar Series - Functional and phenological consequences of host-microbe feedbacks in the pitcher plant mosquito
DESCRIPTION:Description: The purple pitcher plant (Sarracenia purpurea) harbors aquatic communities in its water-filled pitchers long used as a model system in community ecology. One inhabitant\, the pitcher plant mosquito (Wyeomyia smithii)\, is an obligate symbiont of pitcher plants\, developing exclusively inside. By studying the top-down and bottom-up interactions between mosquitoes and aquatic bacterial communities I explore feedbacks between a host organism and its environmentally-acquired microbiota. These cross-trophic interactions have consequences for host fitness and broader ecosystem function. Additionally\, I study host-microbe interactions in the context of mosquito diapause (a hibernation-like state)\, where I explore microbiome-mediated coordination of host seasonal metabolism.

SUMMARY:Workshop / Seminar:EEB Thursday Seminar Series - Do Himalayan birds wear puffy down jackets?
DESCRIPTION:To keep warm\, Himalayan birds may use their plumage for insulation\, fluctuate with metabolic rate to produce body heat\, or escape the cold by migrating downslope. Sahas will discuss how Himalayan bird feather macro-structure is associated with the elevation across 250 species. He will then explore whether there is intra-specific variation within species across their elevational distribution and how it relates with their ecology. Finally\, Sahas will delve down (pun intended) into the brightness and heat absorption capacity of feathers as a means of keeping warm.

SUMMARY:Workshop / Seminar:EEB Student Dissertation Defense - Global change impacts on plant and carbon dynamics in montane meadows
DESCRIPTION:Dissertation abstract: Plant biomass\, a key carbon pool\, is being affected by global changes\, including shifts in plant community composition and changes in abiotic conditions. 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.

SUMMARY:Workshop / Seminar:EEB Tuesday Seminar Series - A holistic framework to assess plants\, pollinators\, and plant-pollinator interactions given novel herbicide exposure
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 (“auxinic”) 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.

SUMMARY:Workshop / Seminar:EEB Thursday Seminar Series - Evolution in Space: Incorporating Geography into Statistical Methods for Population Genetics
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. However\, the development of key statistical methods in population genetics lags behind the generation of datasets that require them for analysis. In particular\, methods for studying population history\, structure\, admixture\, demography\, and selection in continuous space are still lacking\, leading to a gap in our ability to answer basic questions in evolutionary biology. This talk will celebrate Dr. Bradburd's promotion to tenure (woohoo!) and present several vignettes on how geography can be incorporated into population genetics to better understand the processes generating the diversity of life.

SUMMARY:Workshop / Seminar:EEB Tuesday Seminar Series - A bird's-eye view of ecological community under global change
DESCRIPTION:Description: Accelerating environmental change poses an urgent threat to global biodiversity. While we have ample data on species-level responses to global change\, our knowledge of the intricate web of biotic interactions that structure ecological communities remains limited. Using birds of North America\, I present two case studies on how the community composition and species interactions are affected by global change\, especially human-induced land use changes. Then\, I introduce a novel pipeline that enables automatic extraction of species interactions data from citizen science platforms using large language models. Together\, these studies present a new framework on studying the community-level consequences of global change in birds and beyond.

SUMMARY:Workshop / Seminar:EEB Thursday Seminar Series - Synthesizing plant community responses to global change
DESCRIPTION:Seminar Summary - Many global change factors\, such as nitrogen deposition\, herbivore losses\, and species invasions\, are occurring simultaneously worldwide. 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. Through synthesis\, we demonstrate that grassland communities are dynamically changing in their taxonomic\, functional\, and phylogenetic diversity in response to a wide variety of global change drivers\, and that these changes have consequences for ecosystem function.

SUMMARY:Workshop / Seminar:EEB Tuesday Seminar Series - Trait complexity in squamate reptiles and its effects on evolutionary analyses
DESCRIPTION:Description: Functional and phenotypic traits are used as tools for studying evolutionary diversification and ecological interactions. 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.

SUMMARY:Workshop / Seminar:EEB Tuesday Seminar Series -  Effects of lake habitat and carbon supplementation on freshwater microbes mobilizing plastic-derived carbon into the environment
DESCRIPTION:Description: Plastic debris is becoming pervasive in aquatic 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.

My research uses tortoise beetles as a model system to explore the interplay between ecology\, behavior\, and genomics in the evolution of adaptive traits. I will present work from a long-term study of a color polymorphic beetle\, where mate choice experiments\, predator bioassays\, and genomic analyses together reveal how ecological interactions shape and maintain color variation. I will also share new directions from my lab\, including ongoing work on thermal tolerance using chill coma recovery across species and geographic gradients\, paired with transcriptomic approaches.

SUMMARY:Workshop / Seminar:EEB Thursday Seminar Series - Bur oak evolution and its impact on the forest
DESCRIPTION:Seminar Summary - The bur oak (Quercus macrocarpa) is a foundation of eastern North American forests and savannas. It is massive\, long-lived\, strong\, and enormously variable. But the bur oak is no lone wolf: it exchanges genes with other oak species from the Black Hills to Vermont\, and from northern Minnesota to Texas. This talk will provide an overview of ongoing rangewide and reciprocal transplant studies of bur oaks undertaken as part of a collaborative NSF - NSFC Dimensions of Biodiversity project\, “Consequences of diversity in Asian and American tree syngameons for functional variation\, adaptation and symbiont biodiversity.” It will present analyses of genomic\, trait\, mycorrhizal\, and gall wasp data to provide an integrative view of how bur oaks and their relatives shape the forest.

SUMMARY:Workshop / Seminar:EEB RMC Friday Seminar Series - The Nature of Oak Species
DESCRIPTION:Seminar Summary - Plant biologists have debated the nature of oak species for more than 200 years. Opinions range from the view that oak species hybridize relatively rarely to the view that related oaks form syngameons\, near-freely interbreeding complexes of species. Understanding species boundaries and gene flow in oaks is essential to conserving the ca. 425 global oak species on which humans and hundreds to thousands of arthropod\, fungus\, vertebrate\, and plant species depend. In this talk\, I provide an overview of how our understanding of oak species boundaries and hybrids has grown from the early 19th Century to today. Molecular data from the past two decades show that individual oaks exhibit a wide range of mixed-species ancestry\, with as many as 20% of individuals averaged across studies admixed at a level of 10% or higher. This means that hybridization is quite common in many oak species\, and some of the resulting gene flow may play a role in population adaptation and species migration. Nonetheless\, oaks form genetically distinct species\, and that species diversity is crucial to the function of forests\, savannas\, and other oak-dominated forests across much of the northern hemisphere. The lecture will include both historic and recent research.

SUMMARY:Workshop / Seminar:EEB Tuesday Seminar Series - Speciation\, extinction\, and the ecology of macroevolution
DESCRIPTION:Description: The causes of biodiversity patterns at the largest scales of time and space remain poorly understood. In this talk\, I examine the relationship between these dynamic patterns of biological diversity and rates of evolutionary diversification\, and I evaluate progress in linking microevolutionary processes to speciation and extinction at macroevolutionary scales. I argue that biodiversity dynamics across space\, time\, and clades reflect an underlying causal unity shaped by ecological modulation of diversification. However\, further progress will require much deeper integration of traditional microevolutionary biology with population ecology and paleobiology.

SUMMARY:Workshop / Seminar:EEB Thursday Seminar Series - The evolutionary implications of ecological interactions: lessons from agent-based models
DESCRIPTION:Seminar Summary - Eco-evolutionary feedbacks play a powerful role in shaping the trajectory of change in ecological communities. Developing general theory to predict these trajectories would enable a wide variety of innovations in fields ranging from evolutionary medicine to agriculture. I will discuss two vignettes from my lab's work towards developing this theory. First\, a critical step is identifying the ecological interactions that are currently occurring. To this end\, we are exploring the possibility of identifying game theoretic interactions among cancer cells via spatial pattern analysis. A necessary second component is predicting how co-evolution will shape ecological interactions over time. We are studying this problem in the context of host-endosymbiont co-evolution\, using an agent-based computational model. Specifically\, I will present our results on the impact of partner choice on the de novo evolution and stability of mutualism\, and how this impact is affected by the mutational landscape of the trait governing partner choice.

SUMMARY:Workshop / Seminar:EEB Tuesday Seminar Series: Context-dependent collaboration and conflict in microbial mutualisms
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. Increased soil nitrogen\, for example\, causes rhizobia to become less mutualistic\, but this may be due to direct or indirect effects. I experimentally evolved soil microbial communities to disentangle three possible drivers of reduced mutualism-- soil nitrogen\, light\, and host availability-- as well as whether mutualism quality would recover after fertilization cessation. Additionally\, I investigated possible non-additive effects of adding a second symbiont\, arbuscular mycorrhizal fungi\, to the legume-rhizobium system\, because mycorrhizae are an additional carbon sink for plant hosts.
