Dorsal pelage of (Verts and Carraway, 2002)ranges from pale, buffy-gray to dark-gray, and from cinnamon to black. The underside of is white, as are the feet and throat. The tail is markedly bi-colored.
The manus of (Verts and Carraway, 2002)has 4 digits, and the pes has 5 digits.
Most body dimensions of (Verts and Carraway, 2002)are sexually dimorphic. The total length feamles ranges from 281 to 392 mm, with males showing greater variation, and ranging in length from 276 to 407 mm. The tail length of females ranges from 122 to 192 mm, whereas males have a slightly longer tail of 129 to 198 mm. Hind foot lengths for females range from 27 to 38 mm. Males have hind foot lengths ranging from 28 to 38 mm. Ear length of females ranges from 27 to 38 mm, and of males ranges from 28 to 38 mm. Females weigh less than males, ranging from 122 to 240 g compared to the 132 to 350 g weight of males.
Sexual behavior in males requires that the females both emit attractive odors and engage in precopulatory behaviors. Mates may communicate by intense sniffing, vocalization, hop and dart and ear-wiggling responses, grooming, and foot thumping. Males show a pattern of multiple mounts and ejaculation. Although not specifically reported, the sexual dimorphism of these animals suggests that mating is polygynous. (Flemming, et al., 1981; Verts and Carraway, 2002)
These animals apparently live around 3 years in the wild. (Egoscue, 1957)
Houses of desert woodrats are made from twigs, sticks, cactus parts, or rocks. They prefer to build houses in rock crevices, bases of cactus, or in the lower branches of trees. (Brylski, 2000; Egoscue, 1957; Verts and Carraway, 2002)
The home range size has not been reported.
Communication in this species is varied, and entails some chemical, tactile, visual, and accoustic components. Scent marking is sexually dimorphic in (Brylski, 2000; Flemming, et al., 1981; Verts and Carraway, 2002). Males exhibit ventral rubbing more commonly than do females. Females exhibit rolling more than do males. Rubbing may occur in response to odors of conspecifics, after a male encounters a female, or in ares soiled by other individuals. Mates may communicate by intense sniffing, vocalization, hop and dart, and ear-wiggling responses, grooming, and foot thumping.
Canis latrans), swift fox (Vulpes velox), red-tailed hawks (Buteo jamaicensis), and great-horned owls (Bubo virginianus). may also fall victim to conspecifics. (Brylski, 2000; Verts and Carraway, 2002)uses the cover of its house, or hides in boulders to escape predation. The main predators of are coyotes (

young are born in a relatively underdeveloped state; they are unable to feed or care for themselves or locomote independently for a period of time after birth/hatching. In birds, naked and helpless after hatching.
having body symmetry such that the animal can be divided in one plane into two mirror-image halves. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Synapomorphy of the Bilateria.
Found in coastal areas between 30 and 40 degrees latitude, in areas with a Mediterranean climate. Vegetation is dominated by stands of dense, spiny shrubs with tough (hard or waxy) evergreen leaves. May be maintained by periodic fire. In South America it includes the scrub ecotone between forest and paramo.
uses smells or other chemicals to communicate
active at dawn and dusk
in deserts low (less than 30 cm per year) and unpredictable rainfall results in landscapes dominated by plants and animals adapted to aridity. Vegetation is typically sparse, though spectacular blooms may occur following rain. Deserts can be cold or warm and daily temperates typically fluctuate. In dune areas vegetation is also sparse and conditions are dry. This is because sand does not hold water well so little is available to plants. In dunes near seas and oceans this is compounded by the influence of salt in the air and soil. Salt limits the ability of plants to take up water through their roots.
animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a (now extinct) synapsid ancestor; the fossil record does not distinguish these possibilities. Convergent in birds.
