报告人简介:
Dr. Luke Frishkoff received his PhD from Stanford University in 2015 under Drs. Gretchen Daily and Elizabeth Hadly, and was awarded the Ecology and Evolutionary Biology Postdoctoral fellowship from the University of Toronto, where he worked with Dr. Luke Mahler from 2016–2018. He has served as an assistant professor at the University of Texas at Arlington (UTA) since 2018, where his research focuses on reptile and amphibian communities and their responses to anthropogenic stressors. Dr. Frishkoff has over a decade’s experience working in the American tropics, and substantial work in the Caribbean since 2016. His work has been published in prestigious scientific journals including Science, Nature, and the Proceedings of the National Academy of Sciences, as well as the top-tier of ecology and evolutionary biology journals such as Ecology Letters and Global Change Biology.
报告内容简介:
One of the oldest questions in ecology and evolutionary biology is "why are there so many species?" I here address various ways that local interactions with the environment and regional limits on speciation work together to set limits on lizard biodiversity. Lizards are a convenient model for these questions because their ecology is generally well understood, and local communities neither have so few species that one can't see patterns, nor so many that one can't keep track of how individual species contribute to the structure of the community as a whole. Specifically I will discuss my lab's work from across North America and South America as well as the islands of the Caribbean to demonstrate: (i) how urban environments filter the regional species pool to favor specific morphological types of species; (ii) how local aggressive interactions between closely related species set geographic range limits at broad spatial scales; and (iii) whether identical environments in distinct biogeographic regions not only causes the evolution of ecologically similar species, but also causes these species to assemble into communities with similar diversities and abundances of species types.
