Given the rapid loss of amphibian populations, it is crucial that we be able to identify, monitor, and predict factors that may pose threats to native populations. One such threat is establishment and invasion by the African clawed frog, Xenopus laevis. Herein, we develop and validate ecological niche models to predict the potential invasive distribution of this species in North America. Results indicate that a large area, including most of the central and eastern United States, is suitable for the species. Xenopus laevis is potentially a very successful invader, and has been shown to decimate local fauna (including endangered species); as such, it poses a primary threat to native amphibian populations. Because of the enormous popularity in research laboratories and the pet trade of this species, we suggest that further legislation regulating possession of this species, particularly in the central and eastern United States, be pursued.
