Overland movement in African clawed frogs (Xenopus laevis): empirical dispersal data from within their native range [PDF]

open access: yesPeerJ, 2017
Dispersal forms are an important component of the ecology of many animals, and reach particular importance for predicting ranges of invasive species. African clawed frogs (Xenopus laevis) move overland between water bodies, but all empirical studies are ...
