Geobiology podcasts

Carina Hoorn examines how the Amazon Basin’s geological evolution shaped its extraordinary biodiversity. The discussion connects Andean uplift, fresh sediment supply and marine incursions during the Early Miocene with the diversification of aquatic environments and ecological opportunities.

Stephen Porder explores how living organisms have transformed Earth through their use of hydrogen, oxygen, carbon, nitrogen and phosphorus. Drawing on his book Elemental, the conversation connects these biogeochemical changes across deep time with sustainability and choices that could reduce human environmental impacts.
