one of the most struggling issues for conservationists and wildlife managers is the climate change. this can be the necessity to develop climate condition indicators. due to the limited movements and special habitat conditions, pikas can be considered as reliable climate indicators. in this study, the most important climatic factors defining the distribution of this species were investigated to...

Understanding how climatic change impacts biological diversity is critical to conservation. Yet despite demonstrated effects of climatic perturbation on geographic ranges and population persistence, surprisingly little is known of the genetic response of species. Even less is known over ecologically long time scales pertinent to understanding the interplay between microevolution and environment...

The role of global climate change in the decline of biodiversity and the emergence of infectious diseases remains controversial, and the effect of climatic variability, in particular, has largely been ignored. For instance, it was recently revealed that the proposed link between climate change and widespread amphibian declines, putatively caused by the chytrid fungus Batrachochytrium dendrobati...
