SPECIES Microtus (Mynomes) montanus

Author:Peale, 1848.
Citation:Mammalia in Repts. U.S. Expl. Surv., 8: 44.
Common Name:Montane Vole
Type Locality:USA, California, Siskiyou Co., headwaters of Sacramento River, near Mt Shasta.
Distribution:Cascade, Sierra Nevada, and Rocky Mountain ranges: SC British Columbia, Canada, south to EC California, S Utah, and NC New Mexico, USA; disjunct populations in S Nevada, EC Arizona, and WC New Mexico (Frey et al., 1995).
Status:IUCN Data Deficient as M. m. codiensis and M. m. zygomaticus, Vulnerable as M. m. fucosus and M. m. nevadensis, Lower Risk (nt) as M. m. arizonensis and M. m. rivularis, otherwise Lower Risk (lc).
Comments:Subgenus Mynomes, montanus species group (Zagorodnyuk, 1990). Geographic variation and subspecific classification assessed by Anderson (1959), who viewed M. oeconomus as its sister species. Hooper and Hart (1962) arranged M. montanus with M. pennsylvanicus and M. townsendii, a general relationship corroborated by karyotypic and genic analyses (Modi, 1987; Moore and Janecek, 1990). Two karyotypic morphs reported by Judd et al. (1980), who raised the question of their specific distinction. See Sera and Early (2003, Mammalian Species, 716).
