Range contraction and loss of genetic variation of the Pyrenean endemic newt Calotriton asper due to climate change.

Philip de Pous, Albert Montori, Fèlix Amat, Delfí Sanuy. Regional Environmental Change. 24 May 2015. The present study indicates that climate change drastically reduces the potential distribution range of C. asper and reveals dispersal possibilities to be minimal under the most realistic dispersal scenarios. Despite the major loss in suitable climate, the models highlight relatively large stable areas throughout the species core distribution area indicating persistence of populations over time. The results, however, show a major loss of genetic diversity and evolutionary history. Leer más.
