Vulnerability to climate change of a microendemic lizard species from the central Andes

Abstract Given the rapid loss of biodiversity as consequence of climate change, greater knowledge of ecophysiological and natural history traits are crucial to determine which environmental factors induce stress and drive the decline of threatened species.
