Map of the western United States depicting geographic ranges of subspecies of Urocitellus mollis. The Snake River in Idaho delimits the northern range limit of U. m. mollis and the southern range limits of U. m. idahoensis and U. m. artemesiae, and stippling represents the presumed boundary of the latter 2 subspecies.

The “small-eared” species group of Urocitellus ground squirrels (Sciuridae: Xerinae: Marmotini) is endemic to the Great Basin, United States, and surrounding cold desert ecosystems. Most specific and subspecific lineages in this group occupy narrow geographic ranges, and some are of significant conservation concern; despite this, current taxonomy r...

... study reviews the systematics and phylogenetic placement of populations currently attributed to the Piute Ground Squirrel, U. mollis (Kennicott 1863). Urocitellus mollis is the most widely distributed small-eared Urocitellus with 3 subspecies recognized ( Fig. 1; Howell 1938;Rickart 1987;Helgen et al. 2009). The most widespread subspecies, U. m. mollis, occurs throughout a large part of the Great Basin, United States-from the Snake River (Idaho) south to southern Nevada and from the eastern foothills of the Sierra Nevada in California and Nevada east to central Utah. Conversely, U. m. ...

Conversely, U. m. idahoensis (Merriam 1913) and U. m. artemesiae (Merriam 1913) occupy smaller, adjacent ranges in southwestern and southeastern Idaho, respectively, in steppe habitats of the Snake River Plain north of the Snake River (Fig. 1). All 3 subspecies share a common karyotype across the range of U. mollis (2N = 38, FN = 66; Nadler 1966Rickart et al. ...
