Biogeography podcasts

Susanne Renner and Alan Cohen reflect on Bob Ricklefs’s contributions to ecology and evolutionary biology. The discussion considers biogeography, life-history research and the value of sustained, careful scientific work. Ricklefs is the subject of the tribute, rather than a participant in this recording.

Toni Lyn Morelli and Alexej Sirén discuss how climate change alters the geographical distribution of species. As habitats change, movement can offer plants and animals a route to persistence, but it also reshapes ecological relationships. The episode examines these shifts and their implications for conservation and the communities that share affected environments.

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.

Trevor Price discusses the evolution of bird species through research in the Galápagos and Himalayas. The conversation examines reproductive isolation, hybridisation, tropical diversity and elevational limits on distributions, alongside phenotypic plasticity and the practical challenges of studying speciation in the wild.
