Howdy Folks, We have no Ecolunch this week, nor next week (because next Wednesday is a holiday). We will have Ecolunch seminars during the last two weeks of the semester after Thanksgiving, however, so stayed tuned for those! Also, John Schenk in PBIO is giving a talk this Friday at 11:50 in Porter 104. That information is below. See you there! Sincerely, Shawn Kuchta Environmental and Plant Biology Colloquium Series, Fall 2023 [Picture.jpeg][A close-up of a flower Description automatically generated.jpeg][A person smiling at camera Description automatically generated.png] What Evolutionary Processes Drive Species and Morphological Diversification in Plants? John Schenk Environmental and Plant Biology, Ohio University Friday, November 17th at 11:50 AM Room 104, Porter Hall Evolution is a process that has generated a remarkable amount of species diversity and morphological forms that fit into numerous ecological niches, and those factors not only interact with each other, but also influence species diversification. To demonstrate the interactions among those three principles, I highlight three areas of research that have been active in my laboratory: adaptive radiations, edaphic specialization, and staminode evolution. Adaptive radiation studies have elucidated the role of ecological opportunity as a driving force of species diversification across animals and plants. Edaphic specialization studies have demonstrated that some groups have evolved onto restrictive soils numerous times and that those transitions have had a profound effect on their morphology and dispersal ecology, and we are just now beginning to understand the role fitness plays during specialization. Our studies on staminodes (infertile stamens that are often coopted to perform novel functions) have demonstrated dynamic evolutionary histories across clades. Developmental studies have been necessary to assess homology among structures and have been used to test theories of staminode cooption. I conclude the talk by discussing future research projects that answer fundamental questions in evolutionary biology while accounting for the many ways in which morphological, ecological, and species diversity evolves. -------------- next part -------------- An HTML attachment was scrubbed...
