RESUMO
Habitat loss and fragmentation are threatening amphibians by increasing population isolation. However, artificial waterbodies created for livestockmay contrast this phenomenon by providing surrogate habitats for amphibians. Here, we performed a genetic study on an amphibian species, Lissotriton vulgaris meridionalis, in a rural area in central Italy where natural wetlands are disappearing and drinking troughs for cattle watering are widespread. Specifically, we tested a panel of microsatellite markers to identify a suitable tool for addressing conservation genetic issues of this species that is undergoing severe local decline. Twelve of the 20 tested loci produced reliable amplifications and were polymorphic. Three distinct units with a low level of gene flow were distinguished and the population genetic structuring overlapped with geographic distribution. Such loci will be useful to assess the genetic diversity of the species across multiscale levels for its management and conservation.
