Biogeography, Ecology, and Environment: End-Permian Extinction in Southern Gondwana

Our understanding of the causes and effects of the end-Permian extinction on land has been limited to Russia and South Africa. Through fieldwork in Antartica, Tanzania, and Zambia, our team has constructed a regional picture of the event in southern Gondwana. Our results show that the extinction had profound impacts on the food web structures and patterns of endemism. Now we are integrating geochemical data to understand the role of environmental variation in shaping the extinction and recovery.
