Multiscale habitat selection of an imperiled subspecies of Least Chipmunk (Neotamias minimus): when a generalist is really a specialist

Abstract Habitat loss is a leading cause of species endangerment, yet information about habitat is anecdotal for most mammals. The Least Chipmunk (Neotamias minimus) is the most widespread chipmunk in North America and is purportedly a habitat generalist, which should buffer it against habitat loss. However, the southernmost subspecies (Peñasco Least Chipmunk [N. m. atristriatus]) in the Sacramento Mountains of southern New Mexico has declined significantly and has been proposed for listing as endangered under the Endangered Species Act. The declining subspecies presents a conundrum because it could be either a habitat generalist experiencing declines due to factors other than habitat loss or a habitat specialist experiencing habitat loss. We investigated multiscale habitat selection by N. m. atristriatus at the …
