Biological invasions

Biological invasions are now considered as a major threat to Biodiversity across the World. They raise questions about our capacity to predict the spread of an introduced population, the impacts on local ecosystems, the evolutionary responses, and ultimately to control invaders. We have initiated in September 2016 the European Life project CROAA "Control strategies of Alien Amphibians" . Its research objectives are to test alternative control strategies using connectivity modelling, demographic parameters and capture efficiency  in two main invasive amphibians the African clawed frog Xenopus laevis and the Bullfrog Lithobates catesbeianus. Both species have been introduced in France and threatens wetland communities.
