SPECIES Ochotona (Pika) princeps

Author:Richardson, 1828.
Citation:Zool. J., 3: 520.
Common Name:American Pika
Type Locality:"Rocky Mountains"; restricted by Preble (1908) to "near the sources of Elk (Athabasca) River," [Athabasca Pass, head of Athabasca River, Alberta, Canada].
Distribution:Mountains of W North America from C British Columbia (Canada) to N New Mexico, Utah, C Nevada, and EC California (USA).
Status:IUCN Lower Risk (lc); isolated subspecies in the Great Basin: IUCN Vulnerable (goldmani, lasalensis, nevadensis, nigrescens, obscura, sheltoni, tutelata; A. T. Smith et al., 1990).
Comments:Subgenus Pika. Broadbooks (1965) and Youngman (1975) considered princeps and collaris conspecific. Corbet (1978c), following Gureev (1964), included princeps in alpina. A statistical reevaluation of craniometric data by Weston (1981) indicated that princeps, collaris, and alpina are separate species. Hafner and Sullivan (1995) analyzed allozymic variation from 56 populations of princeps, with collaris as outgroup (see above). All but eight of the populations were placed in one of five regional populations, those eight being geographically intermediate. Reviewed by Smith and Weston (1990, Mammalian Species, 352). Allozyme studies revealed 4-5 main groups of populations in this species (Hafner and Sullivan, 1995). Synonyms listed here follow these groupings: (1) Northern Rockies, (2) Central Rockies, (3) Southern Rockies, (4) Sierra Nevada-Great Basin, (5) Cascades.
