Big Biology

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.

David George Haskell discusses the evolution and ecological importance of flowering plants. The conversation follows the innovations that enabled their diversification and their relationships with animals and ecosystems.

Hosted by Clayton Glasgow

Daniel Simberloff discusses biological invasions, ecological theory and evidence from field experiments. The conversation explores how introduced species alter communities and ecosystems, and how long-running research informs conservation and management decisions.

Nachum Ulanovsky discusses studying nervous systems during natural behaviour. The conversation considers what researchers gain from observing animals in ecologically meaningful conditions and how new methods can connect neuroscience with evolution and ecology.
