英文摘要	The goal of this work is to determine and to evaluate threats to Salvator rufescens. The life history of S. rufescens shows a close association with forest habitats, therefore habitat loss and alteration are the main direct threats identified for the species. Indirect consequences of habitat loss are lower reproduction success, higher predation rates and the loss of individuals through road kill. These are therefore additional negative factors within and in the areas surrounding remaining adequate habitat patches. Our findings can serve as a case study showing that, in arid habitats, even formerly abundant species like S. rufescens may be threatened by rapid habitat loss and alteration. In particular the permanent availability of water introduced by livestock farming causes a shift in the composition of native species and may result in a higher predation rate and/or nutrition competition with negative consequences for various autochthonous species.
