Invasion of Asian Spiny Toads in Madagascar

Toad appear to be successful invasive species in many places across the planet. The Asian Spiny Toad represents an important invasion to Madagascar where mesopredators are unfamiliar with toad toxins. My work will be to determine the performance of populations of these animals, and compare them to native populations in Asia.

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.
