SPECIES Microtus (See comments.) californicus

Author:Peale, 1848.
Citation:Mammalia in Repts. U.S. Expl. Surv., 8: 46.
Common Name:California Vole
Type Locality:USA, California, Santa Clara Co., vicinity of San Francisco Bay, San Francisquito Creek near Palo Alto (as fixed by Kellogg, 1918:5).
Distribution:Oak woodlands and grasslands of Pacific coast, from SW Oregon through California, USA, to N Baja California Norte, México.
Status:U.S. ESA – Endangered; IUCN – Vulnerable as M. c. mohavensis and M. c. scirpensis, Data Deficient as M. c. stephensi, Lower Risk (nt) as M. c. vallicola, otherwise Lower Risk (lc).
Comments:Broadly affiliated with other North American Microtus, but evidence for nearest specific relative contradictory (compare assessments of Anderson, 1959; Conroy and Cook, 2000a; Hooper and Hart, 1962; Moore and Janecek, 1990). Zagorodnyuk (1990) acknowledged enigmatic phyletic stature as sole member of californicus species group, subgenus Mynomes. Geographic races delineated by Kellogg (1918); Gill (1980) recorded instances of sterility in hybrids between M. c. californicus and M. c. stephensi.
