Invasion-derived phenotypic divergence: What traits promote invasion success in Guttural Toads?

I propose to use the model system of the Guttural Toad in Africa to understand their invasion success through the investigations of divergent phenotypic traits and rapid, localised evolution. This project will provide insight as to how these invasive populations are adapting to their novel environments. This may in turn provide the foundation for actions to be taken to weaken range expansion potential, (e.g., targeted gene flow). I also plan to utilize a similar research framework to that which has been used in studies of the invasive Cane Toad. This will allow direct comparison between the evolutionary processes and the phenotypic changes that facilitates invasion success in both species of invasive toad.

For the love of crayfish (and more)

My research revolves around understanding the context dependencies of invader impact. I am particularly interested in what species eat - the how’s, why’s and greater implications of trophic interactions. I have been leading the WWF-Zambia freshwater invasion component for the last two years with a focus on the red claw crayfish invasion of the Upper Zambezi. This involved a strategic assessment of invasion status, quantification of ecological impacts at different scales and economic impact assessments. There have been three discrete invasion events in the Upper Zambezi, which provides an opportunity to study the invasion process of the same species at different time frames. Other work involves using species traits to predict impact and strength of biotic interactions, and prediction of aquatic invasive species likely to create management conflicts.
