Phylogenomics of Adaptive Radiation in Antarctic Fishes
Since the onset of polar conditions in the Oligocene, Antarctica's climate has been characterized by periods of global warming and cooling that have had a pronounced impact on its marine biodiversity. In this talk, I will provide an overview of the macroevolutionary history of Antarctic fishes that builds upon insights from phylogenomic, biogeographic, and functional genomic data. These results illustrate links between ecological opportunity, natural selection, and the generation of biodiversity. These findings extend beyond reconstructing events that result in evolutionary innovation, providing critical historical context for forecasting effects of climate change on the stability and evolvability of natural populations.
