Sensitivity to climate change for two reptiles at the Mojave-Sonoran Desert interface

► I address climate change impacts at the Mojave-Sonoran Desert interface. ► Niche models defined the distribution of tortoises and chuckwallas. ► Shifting climate variables indicated where future habitat might occur. ► The species' natural history traits are congruent with modeled climate shifts. ► The shifted niche models identify potential areas of climate-change refugia.
