SUMMARY:Workshop / Seminar:EEB Thursday Seminar Series - Understanding adaptation to anthropogenic disturbance at a global scale
DESCRIPTION:Seminar Summary - Anthropogenic disturbance is a dominant force driving evolutionary change on Earth today. From global land use change\, to resource extraction and consumption\, to rapid and ongoing climate change\, humans are fundamentally changing our planet. While the geochemical\, ecosystem and ecological consequences of anthropogenic caused environmental change are well studied and increasingly understood\, the impacts on evolution are less understood. In this talk I will address this problem by seeking to answer a single general question: How does anthropogenic disturbance influence the evolution of life? As a case example\, I will describe our work on the the cosmopolitan plant white clover\, where we are examining how various anthropogenic disturbances affect all major mechanisms of evolution. I will describe our global studies examining whether urbanization affects phenotypic and genomic evolution. I will then explore whether invasive populations can adapt to novel environments in their invaded range\, including the role of functional traits and structural variants across the genome in these adaptations. Finally\, I will explore whether populations can adapt to rapid climate change through time in introduced and native ranges. The results from the white clover system provide insight into when species are likely to be able to adapt to anthropogenic disturbance\, and when they may be unable to adapt. When combined with studies of other systems\, it is becoming clear that anthropogenic disturbance is becoming one of the most important drivers of evolution.

SUMMARY:Workshop / Seminar:EEB Thursday Seminar Series - The old field rules: the quest to develop generalizable principles about how ecosystems function
DESCRIPTION:Seminar Summary - The presentation will chronicle a journey of long-term research devoted to discovering fundamental principles—rules of life—that explain how animal species’ adaptive evolutionary ecological interactions determine how they control ecosystem functioning. I will discuss how this research journey led to systematic resolution of generalizable principles that explain how ecosystems function. The fundamental lesson is that dedication to long-term theory-informed field research can lead to a coherent predictive understanding of how ecosystems function.

SUMMARY:Workshop / Seminar:EEB Thursday Seminar Series - Variation in life history strategies shapes evolution across the tree of fishes
DESCRIPTION:Seminar Summary - My research explores how ecology and life history strategies drive evolutionary processes and patterns in fishes. Life history strategies have direct links to fitness and vary dramatically among lineages\, and this variation can drive rates and patterns of trait evolution. In this talk I will highlight recent work demonstrating how a migratory life history strategy can influence trait evolution among populations and across clades spanning the fish tree of life. I will also present new research on macroevolution and diversification of lampreys\, an ancient lineage of jawless fishes with remarkably different life history strategies long thought to be linked to a novel speciation process.

SUMMARY:Workshop / Seminar:EEB Thursday Seminar Series - Microbial responses to global change: from microscopic interactions to global patterns
DESCRIPTION:Seminar Summary - The Evans Lab studies microbial ecology and global change. We ask questions about how microbes respond to stressors like climate change\, particularly drought and floods\, and land use change like agricultural intensification. How microbes respond can affect a myriad of ecosystem services\, including soil fertility and crop growth\, and biogeochemical cycles. In this talk I highlight studies in our lab that span microscopic to global. First\, I'll talk about how (and whether) we can generalize microbial responses to a global change\, like drought. We used a network of rainout shelters to ask whether there were taxonomic or trait-based shifts in microbes under drought\, worldwide. We also extend this work to thinking about how microbes interact with plants to buffer plants under drought. Second\, I'll talk about a project investigating bacteria that fix nitrogen\, and how they interact with both the plant and other organisms in the soil\, like fungi. We hypothesized that bacterial-fungal interactions increased nitrogen fixation\, benefitting the plant\, and potentially reducing reliance on nitrogen fertilizers. I will also talk more generally about how these topics connect to global sustainability\, and relevant research at the Kellogg Biological Station Long Term Ecological Research Site.

SUMMARY:Workshop / Seminar:EEB Thursday Seminar Series (Hubbell Lecture) - Variable barriers to gene flow across a field cricket hybrid zone
DESCRIPTION:Seminar Summary - Field crickets (Gryllus) in North America were once considered a single “exceedingly plastic species” adapted to local environmental conditions. There are now more than 35 recognized species of North American field cricket and perhaps many more cryptic undescribed species. With a landmark paper in 1979 titled “Speciation in North American Field Crickets”\, Richard Harrison launched decades of classic studies focused on a single hybrid zone between two closely related species of North American field cricket. In this seminar\, I will revisit hypotheses laid out in the classic paper and describe ongoing work to resolve the phylogenetic relationships among North American Gryllus and identify new hybrid zones in this species complex. I will discuss the natural history of Gryllus and the incredible opportunities for integrative and comparative evolutionary research in this group.
