Topic: introduced species

The Science Show examines mineral nodules formed around fossil shark teeth on the deep-sea floor and the ecological risks of exploiting them. The programme also considers plant responses to climate change, debates over introduced species, and the contributions and limitations of three influential scientists.

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.
