Pocket gophers thrive in a variety of environments and a range of altitudes. [7] For a fossorial animal with a metabolically expensive lifestyle (360–3400 times as much as terrestrial creatures), planning daily activity around burrow temperature, where lack of air flow and high humidity lead to a decrease in evaporative and convective cooling, is likely to be important. They feed mostly on roots of trees, grasses, alfalfa, and dandelions. [7], Males are significantly larger than females, with a total body length of 25 to 35 cm (9.8 to 13.8 in), compared with 21 to 32 cm (8.3 to 12.6 in) in females. "A monograph of the Aphodiini inhabiting the United States and Canada (Coleoptera: Scarabaeidae: Aphodiinae)". They are burrowing animals, found in grasslands and agricultural land across the Great Plains of North America, from Manitoba to Texas. Most pocket gopher species are relatively common and not of conservation concern. Pocket gophers have long incisors that protrude from the mouth, and their eyes are easy to see. Plains Pocket Gophers have a height of 3.5”-5.1” (9-13 cm), body length between 8.2”-13.8” (21-35 cm), and an overall weight in the range of.26-.44 lb (120-200 g). A. Gophers live within loose, social ‘colonies,’ but are primarily solitary with small home ranges. We're on the ground in seven regions across the country, collaborating with 53 state and territory affiliates to reverse the crisis and ensure wildlife thrive. [6], Other adaptations to a fossorial lifestyle include a low resting metabolic rate of 0.946 ml O2/g/h,[3] and high conductance, a tolerance for low oxygen levels and high carbon dioxide levels, and a decreased water intake. Range of the plains pocket gopher (Geomys bursarius) (dark) and Botta’s pocket gopher (Thomomys bottae) (light) in North America. The breeding season varies with latitude, ranging from April to May in Wisconsin to as long as January to September in Texas. It prefers deep sandy and loamy soil in treeless open lands. [3] However, pregnancies lasting up to 51 days have been recorded, and this variation may indicate some form of delayed fertilization, delayed implantation, or delayed zygote development. Eight subspecies are currently recognised, although some former subspecies have since been considered to be species in their own right, and are no longer included: There are about 35 species, all endemic to North and Central America. Pocket gophers create an extensive system of tunnels marked on the surface by numerous mounds of excavated earth. Pocket gophers (Geomyidae), primarily southern Nearctic and extreme northern Neotropical in distribution, are subterra-nean mammals that only infrequently leave their burrows (Hall, 1981). Whitish hairs cover the tops of the feet, while the short, tapered tail is nearly naked. Pocket gopher, (family Geomyidae), any of 38 species of predominantly North and Central American rodents named for their large, fur-lined cheek pouches. Pocket gophers are the most highly fossorial rodents found in North America. The range of plains pocket gopher (G. b. majusculus) extends into Minnesota only in the southern half of the southern border counties. Because they are fossorial and live underground, they prefer moist, porous soils with good drainage. Pocket gophers have a round body, small eyes, short ears and tail, and large, curved claws on the forefeet for digging. The name "Plains Pocket Gopher" is because of their cheek pouches on their cheeks. In their native range, however, pocket gophers are beneficial components of ecosystems. Plenty of vegetation is also favored, as gophers eat plants and use them for structure and protection. [3], The gophers share their tunnels with numerous species of insects, including flies, scarab[10] and carrion beetles,[11] and cave crickets. Factors affecting the size of the tunnel system appeared to be influenced more by the amount of energy needed to maintain and patrol it rather than the amount of vegetation present. Habitat 3. Eight subspecies are currently recognised, although some former subspecies have since been considered to be species in their own right, and are no longer included:[3], Fossil remains have been found as far south as Tennessee, indicating a late Pleistocene, early Holocene population. Pocket gophers are sometimes confused with their fossorial relatives, moles. This Pocket Gopher is related to the Ground Squirrel. Their range extends from St. Clair and Madison counties to east and south of the Illinois River over to the Kankakee River and south of that river to the border of Indiana.

Plains pocket gophers (Geomys bursarius, Fig. This would support the hypothesis that drier environmental conditions with extensive prairies extended further south during the Late Wisconsinan glacial period, supporting populations of Geomys and other prairie species such as thirteen-lined ground squirrels and prairie chickens. Pocket gophers are fossorial rodents named for their fur-lined cheek pouches. [3], Plains pocket gophers typically breed only once a year, although they may sometimes breed twice in good years or warmer climates. They are commonly known for their extensive tunneling activities and their ability to destroy farms and gardens. More than one-third of U.S. fish and wildlife species are at risk of extinction in the coming decades. Loose, sandy soil with edible plant cover is the best habitat for pocket gophers.

The plains pocket gopher (Geomys bursarius) is one of 35 species of pocket gophers, so named in reference to their externally located, fur-lined cheek pouches. The gopher’s home is an extensive system of underground tunnels, which are excavated four to 18 inches below the ground. Duncan's multiple range tests of some cranial measurements showed a clinal increase going from east to west. [8], A long-term controlled study of tunnel excavation by plains pocket gophers found that the rate of tunnel construction ranges from a high of 2,059 cm/week of new tunnels to a low of none over several weeks during the summer. 113 parts of its range. Pocket gopher sign includes large unsightly mounds in yards and mounds in hay fields. A series of these tunnels made by one gopher may extend several hundred feet and cover an acre of grou… Fig. The local vegetation is less significant than the nature of the soil, and the gophers are found in prairie grasslands, agricultural land, and even urban areas.

Plains pocket gophers are found throughout the Great Plains of North America, ranging from southern Manitoba (Canada), and eastern North Dakota south to New Mexico and Texas in the United States, and as far east as the extreme western parts of Indiana. [9] Tunnels include nests, located about 50 cm (20 in) under ground, and lined with grass and other plant material, as well as food caches containing grasses, roots, and tubers. Voracious pocket gophers can leave unsightly dirt mounds in yards, and they readily feed on ornamental garden plants. Search, discover, and learn about wildlife. [4], G. bursarius has short fur with brown to black coloration over the upper body and lighter brown or tan fur on the underparts. Densities of northern pocket gophers have been found to range from 2 to 20 gophers per acre, depending on food availability, species, and ages of the gophers. As part of a continuing and more general study of the diversity of parasites from subterranean mammals in central North America, individuals of the Plains Pocket Gopher, Geomys bursarius bursarius, were collected from 7 localities in northwestern Minnesota from September 1991 through October 1996. The only pocket gopher species in Wisconsin, the Plains Pocket Gopher is distinctive. Although the exact boundaries of the range are uncertain 2, it is smaller than the range assigned to the former Gophers are fossorial herbivores that have a dramatic impact on natural and agricultural ecosystems. Zygomatic arches are widely flared, providing ample room for muscle attachment,[5] although, unlike other pocket gophers, this species does not use the curved incisors to assist the feet in digging. The Pocket Gopher. They do show a bimodal pattern of activity during the day with increased activity occurring from 1300–1700 and then again from 2200–0600.

Loose, sandy soil with edible plant cover is the best habitat for pocket gophers. [3], Plains pocket gophers show no seasonal change in activity, except for an increased level of activity during mating season. [3], Due to the widespread distribution of this species, its adaptability to suitable habitat, the lack of any major threats, and an apparently stable population, G. bursarius has a conservation status of Least Concern. Description . Range and Habitat: The plains pocket gopher lives throughout Kansas with the exception of the southeastern corner of the state. They have special adaptations for their burrowing lifestyle, including clawed front paws for digging, small eyes and ears, and sensitive whiskers and tails. This is especially important when soil has been compacted by grazing livestock or agricultural machinery. Their incisors are ever-growing, which compensates for the tooth wear incurred while chewing on hard, gritty materials.

Several other species are found in the West and Southeast. … Methods and Materials. Often this means pocket gophers make their homes in lawns and crop fields, much to the dismay of homeowners and farmers. The desert pocket gopher is the most threatened species because it occupies a very small range and is thus more vulnerable to habitat loss. The latter is about three and one-fourth inches long. Several other species are found in the West and Southeast. Pocket gophers face numerous threats from predators. The Southeastern pocket gopher (Geomys pinetis) is a fossorial (burrowing) rodent native to the southeastern United States. Fossorial adaptations include small eyes, short, naked ears, and large fore feet with heavy claws. 7-10", tail 2-4". Territorial and aggressive, especially in male-to-male interaction, these rodents appear to use their greatly increased sensitivity to soil vibration to maintain their solitary lifestyle. Botta’s (or val-ley) pocket gophers (Thomomys bottae, In addition, mole tunnels leave raised ridges in the ground, whereas pocket gopher tunnels do not. Adults males weigh from 230 to 473 g (8.1 to 16.7 oz) and females 128 to 380 g (4.5 to 13.4 oz). They stay within burrows and tunnels most of the time. [3], Plains pocket gophers prefer deep, sandy, friable soils to facilitate their burrowing lifestyle and their herbivorous diet of plant roots. Parts of north Missouri are within the range of the plains pocket gopher (Geomys bursarius), a stocky rodent well adapted for subterranean life. Pocket gophers usually live in rangeland, alfalfa fields, roadsides, introduced pastures, railroad rights-of-way, and they often invade lawns and flowerbeds. It lives almost its entire life underground. They also eat seeds, leaves, tender stems, tubers, and bulbs. They are the only natural force that seems to be able to limit the growth of quaking aspen—they can chew the root systems back faster than they can grow back. About 30 to 50 m (98 to 164 ft) of tunnels were open at any one time. Determination of percentages of the soil surface that were bare, covered by litter, and occupied by plant bases showed that gopher-disturbed areas contained greater percentages of bare soil and litter than did undisturbed areas. This gopher has 2 prominent teeth for chewing. [2], The gophers spend 72% of their time in their nests, coming above ground to search for food or mates, and for young animals to establish new burrows.
