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.
