The Gulf Coast kangaroo rat (Dipodomys compactus) is a species of rodent in the family Heteromyidae found in Mexico and the state of Texas in the United States. [3] Its appearance and ecology are very similar to those of its putative sister species, Ord's kangaroo rat. [4]

Description

Adult Gulf Coast kangaroo rats are about 220 mm (8.7 in) long including a tail of about 120 mm (4.7 in). There are two distinct color forms, an ashy gray and a reddish- or yellowish-buff. In both cases the purest color is on the sides and flanks with hairs in the dorsal region having dark tips giving a blackish sheen. The cheeks are white and the ears and upper and lower tail stripes are brown. This species is generally paler in color than other kangaroo rats and can be distinguished from the Ord's kangaroo rat by its shorter, uncrested tail and its shorter, coarser fur. [5]

Distribution

The Gulf Coast kangaroo rat is found in southeastern Texas, southwards from Bexar and Gonzales counties, and in Zapata County, in Mustang Island and Padre Island, just off the coast of Texas, and in the barrier islands off the state of Tamaulipas in Mexico. [1] [5]

Ecology

The Gulf Coast kangaroo rat is mainly nocturnal and feeds on seeds which it collects in its cheek pouches and carries back to its burrow. [1] It lives in sparsely-vegetated locations with sandy soils, often among dunes and normally on the down-wind slope of a dune. Plants found growing in the vicinity include sea oats (Uniola paniculata), bluestem grass (Andropogon), saltgrass (Distichlis), fringe-rushes (Fimbristylis), sunflowers (Helianthus) and croton (Croton). In sparse mesquite (Prosopis) savannah in Texas it is associated with wiregrasses (Aristida), hairy grama (Bouteloua hirsuta) and hooded windmill grass (Chloris cucullata), as well as prickly pear (Opuntia). [5]

Status

The population trend of the Gulf Coast kangaroo rat appears to be steady and no particular threats have been identified. In suitable habitat it is quite common and the IUCN has listed it as being of "least concern". [1]

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.

Heteromyidae is a family of rodents consisting of kangaroo rats, kangaroo mice, pocket mice and spiny pocket mice. Most heteromyids live in complex burrows within the deserts and grasslands of western North America, though species within the genus Heteromys are also found in forests and their range extends as far south as northern South America. They feed mostly on seeds and other plant parts, which they carry in their fur-lined cheek pouches to their burrows.

<span class="mw-page-title-main">Dipodomyinae</span> Subfamily of rodents

Dipodomyinae is a subfamily of heteromyid rodents, the kangaroo rats and mice. Dipodomyines, as implied by both their common and scientific names, are bipedal; they also jump exceptionally well. Kangaroo rats and mice are native to desert and semidesert ecosystems of western North America from southern Canada to central Mexico. They are generally herbivorous foragers, and dig and live in burrows.

The Texas kangaroo rat is a rodent of the family Heteromyidae. It is found in Texas and Oklahoma in the United States, where it often lives in association with brush species, like mesquite and lotebush, growing in areas with firm clay-loam soils. The species is listed as threatened by the Texas Parks and Wildlife Department and the IUCN lists the species as vulnerable.
