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. About 30 to 50 m (98 to 164 ft) of tunnels were open at any one time.
Northern pocket gophers rarely appear above ground; when they do, they rarely venture more than 2.5 feet (0.76 m) from a burrow entrance. Underground, however, they often have tunnels that extend hundreds of feet where they live, store food, and give birth to their young.
Pocket gophers are solitary outside of the breeding season, aggressively maintaining territories that vary in size depending on the resources available. Males and females may share some burrows and nesting chambers if their territories border each other, but in general, each pocket gopher inhabits its own individual tunnel system.
Since pocket gophers are so solitary, any contact that they have with other animals is likely to be with other pocket gophers of their same species. In this way, a certain initial type of lice could be passed on almost exclusively in one species of pocket gopher for generations and generations, producing a new species of louse, specific to one ...
They will live and roam between 0.008 and 0.012 hectares, with tunnel systems anywhere from 200-2,000 square feet. [3] These gophers prefer there to be vegetation above their tunnels and cause heaps of dirt to rise where they surface. [4] In summer, the gophers tunnel where the groundwater supply is about 4.3 feet below the surface.
Richardson's ground squirrel (Urocitellus richardsonii), also known as the dakrat or flickertail, is a North American ground squirrel in the genus Urocitellus.Like a number of other ground squirrels, they are sometimes called prairie dogs or gophers, though the latter name belongs more strictly to the pocket gophers of family Geomyidae, and the former to members of the genus Cynomys.
Desert pocket gophers prefer areas of well-traveled, loose soil, or sandy riverbanks; places that are easy to tunnel into and make a burrow. [2] They are commonly found near open water like rivers, ponds, or irrigation canals. The areas they inhabit are usually skirted by rocky plains or desert. [2]
The genus Geomys contains 12 extant species of pocket gophers [1] often collectively referred to as the eastern pocket gophers. Like all pocket gophers, members of this genus are fossorial herbivores .
