The Wyoming pocket gopher (Thomomys clusius) is a species of gopher that is endemic to the United States. Between 1915 and 1979, it was generally considered to be a subspecies of the northern pocket gopher. [2]
The Wyoming pocket gopher is the smallest species of the genus Thomomys , with a total length of about 17 cm (6.7 in), including a tail about 6 cm (2.4 in) long. Adults weigh from 44 to 72 g (1.6 to 2.5 oz). The fur is a pale yellowish-grey across the upper parts of the body and most of the head, and white on the underparts, feet, and tail. The snout is near black in color. It can be distinguished from the closely related northern pocket gopher by the lack of dark patches on its ears, as well as by its smaller size. [3]
Like other gophers, it has strong front limbs with digging claws, and small ears and eyes. [4] The fur-lined cheek pouches are relatively large, reaching about 44 mm (1.7 in) back from the snout. [3]
The Wyoming pocket gopher is found only in a relatively limited area of southern Wyoming, in eastern Sweetwater County and southwestern Carbon County. [3] It inhabits relatively flat, well-drained areas, often in association with greasewood ( Sarcobatus spp.) [2] and Gardner's saltbush ( Atriplex gardneri ). [5]
In most respects, the Wyoming pocket gopher is thought to be similar in habits and biology to the northern pocket gopher, of which it was formerly considered a subspecies. It is thought to be solitary, living in burrows that are significantly narrower than those of the northern species. [3] It was initially separated from the northern pocket gopher on the basis that it possesses a different karyotype of 2n=46, rather than 2n=48. There is no evidence that the two species are able to interbreed. [2]
The southern bog lemming is a small North American lemming. Its range overlaps with the other species in genus Synaptomys, the northern bog lemming, in southeastern Canada, but extends farther south.
The northern pocket gopher is a small gopher species native to the western United States and the Canadian provinces of Alberta, Saskatchewan, British Columbia, and Manitoba.
Pocket gophers, commonly referred to simply as gophers, are burrowing rodents of the family Geomyidae. The roughly 41 species are all endemic to North and Central America. They are commonly known for their extensive tunneling activities and their ability to destroy farms and gardens.
The smooth-toothed pocket gophers, genus Thomomys, are so called because they are among the only pocket gophers without grooves on their incisors. They are also called the western pocket gophers because they are distributed in western North America. They are considered distinct enough from other pocket gophers to be recognized as a separate subfamily or tribe.
The Mazama pocket gopher is a smooth-toothed pocket gopher restricted to the Pacific Northwest. The herbivorous species ranges from coastal Washington, through Oregon, and into north-central California. Four subspecies of the Mazama Pocket Gopher are classified as threatened under the Endangered Species Act of 1973, including T. m. pugetensis, T. m. tumuli , T. m. glacialis, and T. m. yelmensis. The Mazama Pocket Gopher is one of the smallest of 35 species in the pocket gopher family.
Botta's pocket gopher is a pocket gopher native to western North America. It is also known in some areas as valley pocket gopher, particularly in California. Both the specific and common names of this species honor Paul-Émile Botta, a naturalist and archaeologist who collected mammals in California in 1827 and 1828.
The desert pocket gopher is a species of rodent in the family Geomyidae. It is found in the state of Chihuahua in Mexico and in Texas and New Mexico in the United States.
The plains pocket gopher is one of 35 species of pocket gophers, so named in reference to their externally located, fur-lined cheek pouches. They are burrowing animals, found in grasslands and agricultural land across the Great Plains of North America, from Manitoba to Texas. Pocket gophers are the most highly fossorial rodents found in North America.
The central Texas pocket gopher or Llano pocket gopher is a species of rodent in the family Geomyidae. It is endemic to central Texas in the United States.
Buller's pocket gopher is a species of gopher that is endemic to Mexico.
The camas pocket gopher, also known as the camas rat or Willamette Valley gopher, is a rodent, the largest member in the genus Thomomys, of the family Geomyidae. First described in 1829, it is endemic to the Willamette Valley of northwestern Oregon in the United States. The herbivorous gopher forages for vegetable and plant matter, which it collects in large, fur-lined, external cheek pouches. Surplus food is hoarded in an extensive system of tunnels. The dull-brown-to-lead-gray coat changes color and texture over the year. The mammal's characteristically large, protuberant incisors are well adapted for use in tunnel construction, particularly in the hard clay soils of the Willamette Valley. The gophers make chattering sounds with their teeth; males and females make purring sounds when they are together, and the young make twittering sounds. Born toothless, blind and hairless, the young grow rapidly before being weaned at about six weeks of age.
The Idaho pocket gopher is a species of rodent in the family Geomyidae. It is rather small, with a lightly built skull. Its fur color varies through the body and between individuals. Found in the western United States, it inhabits savannas, shrubland, and grasslands. Individuals live alone in burrows, staying active year-round. Many aspects of its behavior and biology are not well understood. The species is classified as being of least-concern by the International Union for the Conservation of Nature.
The mountain pocket gopher is a species of rodent in the family Geomyidae. It is endemic to California and Nevada. The Sierra Nevada are part of its range.
Townsend's pocket gopher is a species of pocket gopher endemic to the northwestern United States.
The southern pocket gopher is a species of rodent in the family Geomyidae. It is found in Mexico and the United States, usually in high altitude grassland and shrubland. It feeds on plant material and has an extensive burrow above which is a large heap of earth on the surface of the ground.
The hairy yellow-shouldered bat is a species of bat in the family Phyllostomidae native to South America. There are no recognised subspecies.
Knox Jones's pocket gopher is a species of pocket gopher found in Texas and New Mexico. This species is named for Dr. J. Knox Jones Jr. (1929–1992), a prolific mammalogist at Texas Tech University.
The Oriental Basin pocket gopher is a species of pocket gopher which is endemic to Mexico. It was first described in 1895 by Clinton Hart Merriam. It was considered to be a subspecies of Merriam's pocket gopher in the late 20th and early 21st century but has been reinstated as its own species. The IUCN Red List has evaluated it to be of least concern.
The Perote pocket gopher, or Cofre de Perote pocket gopher, is a species of pocket gopher in the family Geomyidae.
