Thomomys talpoides map.svg

The northern pocket gopher (Thomomys talpoides) is a small gopher species native to the western United States and the Canadian provinces of Alberta, Saskatchewan, British Columbia, and Manitoba.

Description

Northern pocket gophers have long rich brown to yellowish brown fur, paler below, with a black patch behind the ear. They weigh 60-160 grams (2-5.5 ounces).

Habitat

Their habitat consists usually of good soil in meadows or along streams; most often in mountains, but also in lowlands. Northern pocket gophers rarely appear above ground; when they do, they rarely venture more than 2.5 feet from a burrow entrance. Underground, however, they often have tunnels that extend hundreds of feet where they live, store food, and mate. [2]

Interactions

According to an article in the Journal of Mammalogy, there are both positive and negative impacts of burrowing by pocket gophers on the organisms around them. Burrowing and grazing have an impact on the plants and the herbivores that consume these plants, even though gophers do not directly interact with the insects in their habitats. Changes in the plants’ composition can cause an increase in soluble amino acids, carbohydrates, chemicals, which causes the plants to be more vulnerable: to parasites, predation, and diseases. [3]

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.

Four subspecies of the Mazama Pocket Gopher are classified as threatened under the Endangered Species Act of 1973, including T. m. pugetensis, T. m. tumuliT. m. glacialis, and T. m. yelmensis. The Mazama Pocket Gopher is one of the smallest of 35 species in the pocket gopher family.

Heterogeomys is a genus of rodent in the family Geomyidae, found in Mexico, Central America and Colombia. Heterogeomys are a small genus of rodents commonly known as pocket gophers, though the term applies to all genera within the family Geomyidae. The name pocket gopher was earned for this family because of their fur lined cheek pouches that can be used for carrying food. These pouches can also be turned inside out. Species of Heterogeomys are regarded as pests, one of less than 5% of rodent species classified as pests, and the history of man's attempts to control their populations reaches back into Mayan times. Despite some efforts to the contrary, populations of Heterogeomys seem to be on a general upwards trend. Furthermore, all of the species of Heterogeomys are considered to be of Least Concern in the World Status Key.

<span class="mw-page-title-main">Columbian ground squirrel</span> Species of rodent

The Columbian ground squirrel is a species of rodent common in certain regions of Canada and the northwestern United States. It is the second largest member of the genus Urocitellus, which is part of the tribe Marmotini, along with marmots, chipmunks, prairie dogs, and other holarctic ground squirrels. They are stout, with short dense fur, which is characteristically tawny across the bridge of the nose. Social encounters sometimes are initiated with kissing behavior and the most common activity above ground is standing at attention. Residing in mountainous terrain and high plains in northern latitudes, they hibernate for 8 to 9 months of the year in burrows, which may be used for many years. They are emaciated when emerging in the spring. The Columbian ground squirrel came to the attention of the scientific community through writings produced by Lewis and Clark, while 21st century molecular genetics has more finely illuminated its ties with other close relatives.

<span class="mw-page-title-main">Camas pocket gopher</span> Small species of burrowing rodent from Oregon

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.

Baird's pocket gopher or the Louisiana pocket gopher is a species of pocket gopher that is native to the southern United States. In total, there are three almost identical species of eastern pocket gopher; Geomys attwateri, G. bursarius, and G. breviceps. G. breviceps is larger in size, G. attwateri is medium-sized and G. bursarius is a bit smaller. Other than by size variation they are not identifiable by external features. Baird's pocket gophers are small rodents with most of their weight on the top half of their bodies.
