SPECIES Thomomys (Thomomys) talpoides
| Author: | Richardson, 1828. | | Citation: | Zool. J., 3: 518. | | Common Name: | Northern Pocket Gopher. | | Type Locality: | Restricted to Canada, Saskatchewan, North Saskatchewan River, Carlton House near Fort Carlton by Bailey (1915:97). | | Distribution: | S British Columbia to C Alberta and SW Manitoba (Canada), south to C South Dakota and N New Mexico, N Arizona, N Nevada, and NE California (USA). | | Status: | IUCN – Vulnerable as T. t. douglasii, Lower Risk (nt) as T. t. limosus and T. t. segregatus, otherwise Lower Risk (lc). | | Comments: | Subgenus Thomomys. Formerly included idahoensis and clusius; see Thaeler (1972) and Thaeler and Hinesley (1979). Partial revision by Bailey (1915) and Thaeler (1985). The considerable degree of chromosomal differentiation among geographic representatives of this form (Thaeler, 1985) suggests that more than one biological species is currently included under the name talpoides. Reviewed by Verts and Carraway (1999, Mammalian Species No. 618) who included pygmaeus, here considered a subspecies of idahoensis (following Thaeler, 1972). |
