The invasion ecology of Guttural toads

While we are starting to get a better picture about the Guttural toad invasions, we still have a lot to learn about their impact both as predators and prey to other species. In his MSc thesis, Sam will try to plot out networks of predators and prey using stable isotopes in both the invasive and native ranges.

Impact of invasive fish on South Africa’s ghost frogs

South Africa boasts a remarkable diversity in stream-adapted endemic anurans, as well as a history in introductions of alien fish. For his Master's thesis, Dan will be looking for evidence of impacts on endemic, stream-adapted anurans by invasive fish in the Cape Fold Mountains. He will also incorporate environmental and habitat variables into a model that will hopefully shed light on which factors would best determine the presence or absence of tadpoles in mountain streams.
