Descriptive notes. Head-body 107-2-119-6 mm, tail 87-1-91-7 mm; weight 53-2-54-1 g. The Panamint Chipmunk is the same size as the Yellow-pine Chipmunk (7. amoenus), but ears and feet are smaller, skull is broader and pelage is paler. Pelage is more red than pelage of the Least Chipmunk (7. minimus), and baculum is similar to that of the Lodgepole Chipmunk (7: speciosus). Chromosome number of the Panamint Chipmunk is 2n = 38. The karyotype is type B for Tamias and consists of five pairs of metacentric autosomes, six pairs of submetacentric autosomes, seven pairs of acrocentric autosomes, a submetacentric X chromosome, and an acrocentric Y chromosome.
Habitat. Upper Sonoran and transition zones, mostly in pinyon-juniper forests (Finus, Pinaceae; Juniperus, Cupressaceae), but also stands of limber pine (P. flexilis) and bristlecone pine (P. aristata), in higher elevations. The Panamint Chipmunk occurs at elevations of ¢.1230-3180 m, and is usually associated with rocky cliffs, ledges, and crevices.
Food and Feeding. Diet consists mostly of the seeds ofjuniper (Juniperus) and pinyon pine (Pinus), but also includesfruits, leaves, flowers, and arthropods.
Breeding. Gestation lasts ¢.36 days or more. Based on embryo counts of four females, average litter size was estimated to be 5-7 (range 4-9).
Activity patterns. The Panamint Chipmunk is terrestrial, although sometimes it climbs trees. [tis diurnal and appears to be a facultative hibernator, active during winter when weather is mild. When threatened, it seeks refuge in rocks.
Movements, Home range and Social organization. There is no information available for this species.
Status and Conservation. Classified as Least Concern on The IUCN Red List. The subspecies acrus is not abundant and is isolated in an area of 100 km* The Panamint Chipmunk is common in suitable environments and current population trend is stable; there are currently no major threats. Proper management and conservation of this species may be compromised due to a lack of information about behavior and ecology.
