Andrews's three-toed jerboa, or the Mongolian jerboa, (Stylodipus andrewsi) is a species of rodent in the family Dipodidae. It is found in China (Inner Mongolia, Gansu, and Ningxia provinces) and Mongolia. [1] [2]
Andrews's three-toed jerboa grows to a length of 113 to 130 mm (4.4 to 5.1 in) with a tail rather longer than its body and a weight of about 60 grams (2.1 oz). The crown of the head is grey with white spots above the eye and another behind the ear. The rest of the coat is buffish grey. A white band stretches across the hips and the underparts are white. The central toe on the hind foot is the longest and the sole of the foot is haired. The tail is thickened by the adipose tissue beneath the skin and has a flattened, terminal, black bushy section. It can be distinguished from the rather similar thick-tailed three-toed jerboa (Stylodipus telum) by the fact that it has premolars in the upper jaw, these being vestigial in S. telum. [3]
Andrews's three-toed jerboa is nocturnal and is a solitary animal. It inhabits semi-arid and arid steppes and grassland, as well as sand dunes with scrubby vegetation. It is also found in coniferous and mixed forests with undergrowth. It feeds on green parts of plants, roots and seeds. Females usually have a single litter consisting of two to four young in the year. [3]
Andrews's three-toed jerboa has a wide range and presumed large total population and occurs in a number of protected areas. No particular threats to this species have been identified and Its population trend is unknown. The International Union for Conservation of Nature has assessed its conservation status as being of "least concern". [1]
Jerboas form the bulk of the membership of the family Dipodidae. Jerboas are hopping desert rodents found throughout Arabia, Northern Africa and Asia. They tend to live in hot deserts.
The Dipodidae, or dipodids, are a family of rodents found across the Northern Hemisphere, the sole family in the superfamily Dipodoidea. This family includes over 50 species among the 16 genera. They include the jerboas, jumping mice, and birch mice. Different species are found in grassland, deserts, and forests. They are all capable of saltation, a feature that is most highly evolved in the desert-dwelling jerboas.
The four-toed jerboa is a rodent of the family Dipodidae and genus Allactaga that has four digits. It is the sole species in the subgenus Scarturus. Four-toed jerboas are native to Egypt and Libya. They live in coastal salt marshes and dry deserts.
The Balikun jerboa is a species of rodent in the family Dipodidae. It is found in arid areas of northwestern China and Mongolia. It eats green plants, plant roots, seeds, grasshoppers and beetles.
The Gobi jerboa is a species of rodent in the family Dipodidae. It is found in China and Mongolia. Its natural habitats are temperate grassland and temperate desert.
The great jerboa is a species of rodent in the family Dipodidae. It is found in Kazakhstan, Russia, Turkmenistan, Ukraine and Uzbekistan. It mainly lives in deserts.
The Mongolian five-toed jerboa or Siberian jerboa is a species of rodent in the family Dipodidae. It is found in China, Kazakhstan, Mongolia, and Turkmenistan.
The five-toed pygmy jerboa is a species of rodent in the family Dipodidae. It is monotypic within the genus Cardiocranius. It is found in China, Kazakhstan, and Mongolia.
The northern three-toed jerboa is a species of rodent in the family Dipodidae. It is monotypic within the genus Dipus. It ranges across Iran, Uzbekistan, Turkmenistan, Kazakhstan, Russia, China and Mongolia. A common species, the International Union for Conservation of Nature rates it as being of "least concern".
The thick-tailed pygmy jerboa is a species of rodent in the family Dipodidae. It is found in China, Kazakhstan, and Mongolia. Its natural habitats are temperate grassland and temperate desert. It is threatened by habitat loss. It is listed by the IUCN as being "least concern".
Kozlov's pygmy jerboa is a species of rodent in the family Dipodidae. It is found in northwestern China and southern and eastern Mongolia. Its natural habitat is temperate desert.
The Baluchistan pygmy jerboa, or the dwarf three-toed jerboa, is a species of rodent in the family Dipodidae. It is the only species in the genus Salpingotulus. Adults average only 4.4 cm (1.7 in) in head and body length, with the tail averaging 8 cm (3.1 in). Adult females weigh 3.75 g (0.132 oz). It is currently considered to be endemic to Pakistan. In the 1999 Guinness Book of Records, it was listed as tied for the smallest rodent in the world with the African pygmy mouse.
