[3], Plains pocket gophers typically breed only once a year, although they may sometimes breed twice in good years or warmer climates. A. They are eaten by animals that are able to follow them into burrows, such as weasels and snakes. 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. 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: Pocket gophers have a round body, small eyes, short ears and tail, and large, curved claws on the forefeet for digging. stems) eaten by plains pocket gophers in western Nebraska. 7-10", tail 2-4". The Pocket Gopher. They range from Panama in the south to Alberta in the north. A Plains Pocket Gopher is a rodent. Size 3. Pocket gophers (Geomyidae), primarily southern Nearctic and extreme northern Neotropical in distribution, are subterra-nean mammals that only infrequently leave their burrows (Hall, 1981). Abandoned tunnels provide habitat for a number of other species, and the waste left behind by pocket gophers fertilizes the soil. Pocket gophers are fossorial rodents named for their fur-lined cheek pouches. They are used for carrying food up to 7 cm (2.8 in) in length and have a forward opening. [3], Plains pocket gophers show no seasonal change in activity, except for an increased level of activity during mating season. Although the exact boundaries of the range are uncertain 2, it is smaller than the range assigned to the former Animal Diversity Web, University of Michigan Museum of Zoology, Minnesota Department of Natural Resources. There are several easy ways to tell the two groups apart. While focusing on the differences between these two species, it is worthwhile to point out gophers are generally considered as pests to rangelands, agricultural fields and in suburban lawns and property. 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. [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. [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 prefer sandy soils. 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. The mother takes care of the young for several weeks before sending them on their way to construct burrows of their own. Comments : Taxonomy: Order: Rodentia (rodents) Suborder: Myomorpha : Superfamily: Geomyoidea : Family: Geomyidae (pocket gophers) Subordinate Taxa: Parts of north Missouri are within the range of the plains pocket gopher (Geomys bursarius), a stocky rodent well adapted for subterranean life. … Pocket gopher sign includes large unsightly mounds in yards and mounds in hay fields. Ge­o­graphic Range. They’re also able to close their lips behind their long incisors so they can use their teeth to loosen soil without getting any dirt in their mouths. Young pocket gophers are born in nest chambers underground. This is especially important when soil has been compacted by grazing livestock or agricultural machinery. Most pocket gopher species are relatively common and not of conservation concern. [4], G. bursarius has short fur with brown to black coloration over the upper body and lighter brown or tan fur on the underparts. "Small carrion beetles (Coleoptera: Leiodidae: Cholevinae) from burrows of, "Insects inhabiting the burrows of the Ozark pocket gopher in Arkansas", https://en.wikipedia.org/w/index.php?title=Plains_pocket_gopher&oldid=985071020, Fauna of the Plains-Midwest (United States), Articles with unsourced statements from August 2011, Creative Commons Attribution-ShareAlike License, This page was last edited on 23 October 2020, at 19:41. Plains pocket gophers (Geomys bursarius, Fig. The tunnels also serve to capture snowmelt and rainfall that would otherwise run over the soil surface and cause erosion. Pocket gophers thrive in a variety of environments and a range of altitudes. President and CEO Collin O’Mara reveals in a TEDx Talk why it is essential to connect our children and future generations with wildlife and the outdoors—and how doing so is good for our health, economy, and environment. The gopher’s home is an extensive system of underground tunnels, which are excavated four to 18 inches below the ground. They move enormous amounts of soil every year, and therefore help to aerate the soil. estimate survival rates of plains pocket gophers. In 4 seconds, you will be redirected to nwfactionfund.org, the site of the National Wildlife Action Fund, a 501(c)(4) organization. Their cheek pouches, or pockets, are used for transporting bits of plant food that they gather while foraging underground. The name pocket gopher on its own may refer to any of a number of genera within the family Geomyidae. Pocket gophers usually live in rangeland, alfalfa fields, roadsides, introduced pastures, railroad rights-of-way, and they often invade lawns and flowerbeds. However, the benefit-costanalysis of The “pockets” open externally on each side of the mouth and extend from the face to the shoulders; they can be everted for cleaning. The most widespread North American species is the plains pocket gopher, which is found throughout the Great Plains region. [12] Known predators include rattlesnakes, prairie kingsnakes, gopher snakes, feral cats, coyotes, foxes, badgers, hawks, and owls. [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. Their incisors are ever-growing, which compensates for the tooth wear incurred while chewing on hard, gritty materials. They begin to develop fur at 10 days, open their eyes at three weeks, and are weaned by five weeks of age. The tail length of a Plains Pocket Gopher is 2”-4.7” (5-12 cm). In their native range, however, pocket gophers are beneficial components of ecosystems. The breeding season varies with latitude, ranging from April to May in Wisconsin to as long as January to September in Texas. Pocket Gopher damage includes chewing of any underground lines including electric, water and septic piping. Llanos pocket go­phers, Ge­omys tex­en­sis, are lo­cated ex­clu­sively in Texas. Previous radio telemetry studies on plains pocket gophers did not include estimates for survival rates, having focused on home range estimates and behavior (Artmann, 1967; Zinnel, 1992; Benedix, 1994). Loose, sandy soil with edible plant cover is the best habitat for pocket gophers.
