Chihuahuan Pocket Mouse
The Chihuahuan pocket mouse (''Chaetodipus eremicus'') is a species of Heteromyidae, heteromyid rodent found in the southwestern United States and Mexico. It was formerly considered a subspecies of the desert pocket mouse (''C. pencillatus''), but was determined to be a distinct species in 1996, following analysis of its mitochondrial DNA. Description Chihuahuan pocket mice are moderately sized rodents, with a total adult length of , including the tail, and weighing . The fur is buff sprinkled with black over the back and sides, and white on the tail and underparts. The hairs on the rump are long and slender, but there are no spines, such as are present on the otherwise very similar rock pocket mouse. The tail is long, measuring , and ends in a large tuft of white fur. The mice are herbivorous, mainly feeding on the seeds of plants such as Gutierrezia sarothrae, broomweed, mesquite, and creosotebush, although they will also eat grasses when seeds are in short supply. They are noc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chihuahuan Desert
The Chihuahuan Desert ( es, Desierto de Chihuahua, ) is a desert ecoregion designation covering parts of northern Mexico and the southwestern United States. It occupies much of far West Texas, the middle to lower Rio Grande Valley and the lower Pecos Valley in New Mexico, and a portion of southeastern Arizona, as well as the central and northern portions of the Mexican Plateau. It is bordered on the west by the Sonoran Desert, the Colorado Plateau, and the extensive Sierra Madre Occidental range, along with northwestern lowlands of the Sierra Madre Oriental range. Its largest, continual expanse is located in Mexico, covering a large portion of the state of Chihuahua, along with portions of Coahuila, north-eastern Durango, the extreme northern part of Zacatecas, and small western portions of Nuevo León. With an area of about , it is the largest desert in North America. The desert is fairly young, existing for only 8000 years. Geography There are several larger mountain ranges ...

Fauna Of The Western United States
The fauna of the United States of America is all the animals living in the Continental United States and its surrounding seas and islands, the Hawaiian Archipelago, Alaska in the Arctic, and several island-territories in the Pacific and in the Caribbean. The U.S. has many endemic species found nowhere else on Earth. With most of the North American continent, the U.S. lies in the Nearctic, Neotropic, and Oceanic faunistic realms, and shares a great deal of its flora and fauna with the rest of the American supercontinent. An estimated 432 species of mammals characterize the fauna of the continental U.S. There are more than 800 species of bird and more than 100,000 known species of insects. There are 311 known reptiles, 295 amphibians and 1154 known fish species in the U.S. Known animals that exist in all of the lower 48 states include white-tailed deer, bobcat, raccoon, muskrat, striped skunk, barn owl, American mink, American beaver, North American river otter and red fox. ...

Chaetodipus
''Chaetodipus'' is a genus of pocket mouse containing 17 species endemic to the United States and Mexico. Like other members of their family such as pocket mice in the genus ''Perognathus'', they are more closely related to pocket gophers than to true mice. Characteristics Members of this genus range in size from 80 to 125 mm (head and body) and weigh 15–47 grams (Nowak, 1999). Unlike the silky pocket mice (genus ''Perognathus''), most species of the genus ''Chaetodipus'' have harsh pelage with some bordering on spiny hair. They tend to be found in arid habitats where they feed on seeds, vegetation, and insects (Nowak, 1999). Females give birth to a litter of 2–9 young after a gestation period of just under a month. The longest recorded life span is 8 years and 4 months (Nowak, 1999).

Opuntia
''Opuntia'', commonly called prickly pear or pear cactus, is a genus of flowering plants in the cactus family Cactaceae. Prickly pears are also known as ''tuna'' (fruit), ''sabra'', ''nopal'' (paddle, plural ''nopales'') from the Nahuatl word for the pads, or nostle, from the Nahuatl word for the fruit; or paddle cactus. The genus is named for the Ancient Greek city of Opus, where, according to Theophrastus, an edible plant grew and could be propagated by rooting its leaves. The most common culinary species is the Indian fig opuntia (''O. ficus-indica''). Description ''O. ficus-indica'' is a large, trunk-forming, segmented cactus that may grow to with a crown of over in diameter and a trunk diameter of . Cladodes (large pads) are green to blue-green, bearing few spines up to or may be spineless.

Torpor
Torpor is a state of decreased physiological activity in an animal, usually marked by a reduced body temperature and metabolic rate. Torpor enables animals to survive periods of reduced food availability. The term "torpor" can refer to the time a hibernator spends at low body temperature, lasting days to weeks, or it can refer to a period of low body temperature and metabolism lasting less than 24 hours, as in "daily torpor". Animals that undergo daily torpor include birds (even tiny hummingbirds, notably Cypselomorphae) and some mammals, including many marsupial species, rodent species (such as mice), and bats. During the active part of their day, such animals maintain normal body temperature and activity levels, but their metabolic rate and body temperature drop during a portion of the day (usually night) to conserve energy. Some animals seasonally go into long periods of inactivity, with reduced body temperature and metabolism, made up of multiple bouts of torpor. This is kno ...

Heteromyidae
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 down as far 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. Although they are very different in physical appearance, the closest relatives of the heteromyids are pocket gophers in the family Geomyidae. Description There are about fifty-nine members of the family Heteromyidae divided among six genera. They are all small rodents, the largest being the giant kangaroo rat (''Dipodomys ingens'') with a body length of and a tail a little longer than this. In many species the tail is tufted and is mainly used for balance. Other adaptations include partially fused vertebrae in the neck ...

Creosotebush
''Larrea tridentata'', called creosote bush and greasewood as a plant, chaparral as a medicinal herb, and ''gobernadora'' (Spanish for "governess") in Mexico, due to its ability to secure more water by inhibiting the growth of nearby plants. In Sonora, it is more commonly called ''hediondilla''; Spanish ''hediondo'' = "smelly". It is a flowering plant in the family Zygophyllaceae. The specific name ''tridentata'' refers to its three-toothed leaves. Distribution ''Larrea tridentata'' is a prominent species in the Mojave, Sonoran, and Chihuahuan Deserts of western North America, and its range includes those and other regions in portions of southeastern California, Arizona, southern Nevada, southwestern Utah, New Mexico, and Texas in the United States, and Chihuahua, Sonora, Coahuila, Nuevo León, Zacatecas, Durango and San Luis Potosì in Mexico. The species grows as far east as Zapata County, Texas, along the Rio Grande southeast of Laredo near the 99th meridian west. ...
