High habitat invasibility unveils the invasiveness potential of water frogs

Determining the invasibility of habitats by alien species is crucial for understanding their spread potential, most at risk and to implement adequate management actions. This urgent introduced taxa that show high invasion potential across broad geographical scales. We here assess these processes in invasive Pelophylax water frogs which are widespread colonizers Western Europe remains be quantified. Specifically, we used hierarchical occupancy models a Bayesian framework identify local- landscape-scale features can enhance common frog, marsh frog (P. ridibundus), southern France. Water were highly detectable showed invaded landscape. The invaders expressed very habitat tolerance both variables while was facilitated occurrence deep, permanent ponds with abundant aquatic vegetation sun exposure.
