Dipodomys

Dipodomys merriamiMerriam's kangaroo rat, dipodomys, is a rodent found in the arid regions dipodomys the southwest United States and Mexico. Dipodomys merriami are sand-dwelling mammals that inhabit arid regions of dipodomys southwestern United States and Mexico.

The giant kangaroo rat is the largest member of the family that includes kangaroo rats, kangaroo mice and pocket mice. Named for its unique two-footed hopping movements, the giant kangaroo rat lives in grassland areas generally along the western edge of California's San Joaquin Valley from Fresno County in the north to Kern County in the south and the Carrizo Plain and Cuyama Valley in San Luis Obispo County. They were listed as endangered in April The giant kangaroo rat has a large, flattened head and a short neck. Large, fur-lined cheek pouches are used to store and carry seeds found while foraging. Their tails are longer than their combined head and body length. The tails have a crest of long hairs, terminating in a large tuft.

Dipodomys

Ord's kangaroo rat Dipodomys ordii is a kangaroo rat native to western North America , specifically the Great Plains and the Great Basin , with its range extending from extreme southern Canada to central Mexico. Ord's kangaroo rat has a fifth toe on its hip feet, which distinguishes it from Dipodomys elator. It is bicolored with gold-brown dorsal hair and a white stomach. It has a long tail with a bushy tip, and is dark dorsally and ventrally with a white lateral stripe. Its hind feet are modified for jumping, and exceed 35 mm in length, and its total length exceeds mm. Its tail is usually less than mm, distinguishing it from D. Though a common species in the United States , the population in Canada is considered endangered. The currently accepted scientific name for Ord's kangaroo rat is Dipodomys ordii Woodhouse. It belongs to the family Heteromyidae, kangaroo rats and mice. Hall [5] listed 35 subspecies, but Kennedy and Schnell reported many of these subspecies are probably not legitimate since they were based on the assumption of little sexual dimorphism in the species. It has now been established that sexual dimorphism within the taxon is considerable. Ord's kangaroo rat ranges from southern Alberta and southern Saskatchewan to southern Hidalgo , Mexico , and from central Oregon and eastern California east to central Kansas and Oklahoma. Ord's kangaroo rats occur mainly in semiarid, open habitats.

Dipodomys agilis Dipodomys californicus Dipodomys compactus Dipodomys deserti Dipodomys elator Dipodomys elephantinus Dipodomys gravipes Dipodomys heermanni Dipodomys ingens Dipodomys merriami Dipodomys microps Dipodomys nelsoni Dipodomys nitratoides Dipodomys ordii Dipodomys panamintinus Dipodomys phillipsii Dipodomys simulans Dipodomys spectabilis Dipodomys stephensi Dipodomys venustus. Kangaroo rats , small mostly nocturnal rodents of genus Dipodomys , are native to arid areas of western North America. The common name derives from their bipedal form. They hop in a manner similar to the much larger kangaroo , but developed this mode of locomotion independently , like several other clades of rodents e. Kangaroo rats are four or five-toed heteromyid rodents with big hind legs, small front legs, and relatively large heads. Adults typically weigh between 70 and grams 2.

Desert kangaroo rats inhabit dunes in the most arid regions of southwestern North America. They occur at elevations ranging from 60 meters below sea level in Death Valley, California, to 1, meters in Huntoon Valley, Nevada Best et al. Dipodomys deserti is adapted to live in the lowest, hottest, and most arid regions of North America Nader, The number of sand dunes may limit the distribution of D. In contrast to larger members of the genus, desert kangaroo rats occur in areas that receive little precipitation. To compensate for the extreme and prolonged aridity of the region, they are restricted to sand dunes, which harbor richer food sources. Burrows are typically made in areas which are not highly ephemeral.

Dipodomys

Dipodomys ordii are the most widespread of all Kangaroo rats. They are found through much of western North America from Saskatchewan to Mexico. The Kansas plains, Great Sandhills of Sakatchewan and the California sagebrush are all common habitats. In general, D. Open ground is better for this animal, as it has been observed that an increase in grass cover leads to a decrease in population. Their burrows are rarely located in hard and gravelly soils and they are one of the few animals that are able to establish in shifting dunes Banfield ; Davis and Schmidly

Groups of kangaroo rats that exist are aggregations and colonies. When an unknown object is encountered these kangaroo rats are is known to kick sand at the object to determine whether it is alive and if it is a threat. The skull is sciuromorphous with dramatically inflated auditory bullae. Foraging activity is greatest in the spring as seeds of annual plants ripen. Characteristic category. In New Mexico, Ord's kangaroo rat annual home ranges in mesquite averaged 3. Southwestern Naturalist. Goodall, David W. In contrast to larger members of the genus, desert kangaroo rats occur in areas that receive little precipitation. These threats include:. Hall [5] listed 35 subspecies, but Kennedy and Schnell reported many of these subspecies are probably not legitimate since they were based on the assumption of little sexual dimorphism in the species. After curing for several weeks, they move the seeds to underground storage areas. This may help to dry them off.

Heteromyidae: information 1 Heteromyidae: pictures 9 Heteromyidae: specimens They collect and disperse seeds much of the time that they are out of their burrows. These strong rear legs enable the species to hop from place to place and help them quickly get out of the way of predators, such as snakes. Hall [5] listed 35 subspecies, but Kennedy and Schnell reported many of these subspecies are probably not legitimate since they were based on the assumption of little sexual dimorphism in the species. Their reproductive output is highest in summer following high rainfalls. However, these colonies rarely last for long periods of time and will be moved when food is scarce Best et al. The lowest number of females in breeding condition occurred in November, but at least a few females were breeding at that time. Ryan, N. Archived from the original on They have specialized kidneys which allow them to dispose of waste material with very little output of water.
