Dunn's gerbil (Gerbillus dunni) is a rodent species distributed mainly in Eritrea, Ethiopia, Somaliland and Djibouti. It is an animal of dry grassland and rocky plains. It is also sometimes called the "Somalia gerbil", not to be confused with the Somalian gerbil or the Somali gerbil.
Dunn's gerbil was first described by the British zoologist Oldfield Thomas as Gerbillus dunni in 1904. Its karyotype is 2n=74. [2] Its natural habitat is not under threat and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
Dunn's gerbil is one of eight very similar species of gerbil native to northeastern Africa, the others being Berbera gerbil (G. acticola), Brockman's gerbil (G. brockmani), cushioned gerbil (G. pulvinatus), Harwood's gerbil (Dipodillus harwoodi), least gerbil G. pusillus, Somalian gerbil Dipodillus somalicus and Waters's gerbil (G. watersi). Dunn's gerbil can be distinguished from the others by the hairy soles to its hind feet. The head-and-body length is about 98 mm (3.9 in) and the tail 135 mm (5.3 in). The mass is about 38 g (1.34 oz). [3]
Dunn's gerbil is native to the Horn of Africa. Its range includes Eritrea, Djibouti, eastern Ethiopia and northern Somalia. Its typical habitat is bare or scantily-vegetated, rocky plains, dry grassland and dry savannah. [1]
Dunn's gerbil is present in a large area of suitable habitat. No particular threats have been identified and the population is believed to be steady, and although it is seldom seen, its population is presumed to be large. The International Union for Conservation of Nature has rated its conservation status as being of "least concern". [1]
Gerbillinae is one of the subfamilies of the rodent family Muridae and includes the gerbils, jirds, and sand rats. Once known as desert rats, the subfamily includes about 110 species of African, Indian, and Asian rodents, including sand rats and jirds, all of which are adapted to arid habitats. Most are primarily active during the day, making them diurnal, and almost all are omnivorous.
The Berbera gerbil is distributed mainly in Somalia, but its range may extend into Ethiopia and Djibouti. It is endemic to the Ethiopian xeric grasslands and shrublands ecoregion.
The Balochistan gerbil or dwarf gerbil, is distributed mainly from Morocco across north Africa, the Arabian Peninsula, the Middle East, and western Asia. This is a common species with a wide distribution which faces no obvious threats, so the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
Botta's gerbil is a species of gerbil endemic to Sudan and possibly northern Kenya. According to the International Union for Conservation of Nature, it was listed as Least Concern in 1996 until it was listed as Data Deficient in 2004. According to a 2013 book, it is known from a few specimens taken from four or five localities in a small area between the rivers White Nile and Blue Nile; its habitat is fields of vegetables and cereals. Aside from this information, nothing else is known about the species including its population and threats.
The lesser Egyptian gerbil is a small species of rodent in the family Muridae. It is native to North Africa and the Sinai Peninsula, where it lives in sandy habitats. It is a common species, and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
Cheesman's gerbil is a small rodent in the subfamily Gerbillinae of the family Muridae. It is distributed mainly in Arabian Peninsula to southwestern Iran. It has orange-brown fur, white underparts, large eyes and a very long tail.
Anderson's gerbil is a species of rodent distributed from Tunisia to Israel. Their habitats and diets are similar to other gerbils. The gestation period is 20–22 days and the average litter size is four or five. The IUCN formerly listed the junior synonym Gerbillus allenbyi as vulnerable.
The greater Egyptian gerbil is a small rodent in the family Muridae. It is native to northern Africa where it inhabits sandy deserts, semi-arid areas and oases. It is a common species, and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
Gerbillus is a genus that contains most common and the most diverse gerbils. In 2010, after morphological and molecular studies Dipodillus was ranged as a subgenus of Gerbillus, however some taxonomic authorities continue to separate them.
The North African gerbil is a species of rodent in the family Muridae. It is found in North Africa where its natural habitats are arable land and rocky areas of the Maghreb, and hot Saharan deserts.
Dipodillus is a genus of rodent in the family Muridae. It is sometimes classified as a subgenus of the genus Gerbillus.
The rupicolous gerbil is a species of rodent in the family Muridae. It is found only in Mali. Its natural habitats are dry savanna and rocky areas.
The tiny fat mouse is a species of rodent in the family Nesomyidae. It is found in Angola, Botswana, Ethiopia, Kenya, Mozambique, Namibia, South Sudan, Tanzania, Uganda, Zambia, and Zimbabwe. Its natural habitats are subtropical or tropical dry shrubland and subtropical or tropical dry lowland grassland.
The fringe-tailed gerbil is a species of rodent found in Central African Republic, Chad, Eritrea, Ethiopia, Kenya, Niger, Somalia, Sudan, Tanzania, Uganda, possibly Cameroon, and possibly Nigeria. Its natural habitats are dry savanna, moist savanna, subtropical or tropical dry lowland grassland, arable land and urban areas.
Harrington's gerbil or Harrington's tateril is a species of rodent found in the Central African Republic, Ethiopia, Kenya, Somalia, South Sudan, Tanzania, and Uganda. Its natural habitats are dry savanna, subtropical or tropical dry shrubland, and subtropical or tropical dry lowland grassland. It is sometimes considered to be conspecific with Emin's gerbil, because it has the same karyotype.
Archer's lark, also known as the Liben lark, is a species of lark in the family Alaudidae. It is found in Somalia and Ethiopia. Its natural habitats are subtropical or tropical dry shrubland and subtropical or tropical dry lowland grassland. It is threatened by habitat loss. The bird's common name and binomial commemorate the British explorer and colonial official Sir Geoffrey Francis Archer.
The little brown bustard is a species of bird in the family Otididae. Found in Ethiopia and Somalia, its natural habitats are subtropical or tropical dry shrubland and subtropical or tropical dry lowland grassland. As indicated by its name, this bustard is the world's smallest at 45 cm (18 in) and 600 grams (1.3 lb). It is threatened by habitat destruction.
The unstriped ground squirrel is a species of rodent in the family Sciuridae. It is the only member of the genus Xerus. It is found in Djibouti, Eritrea, Ethiopia, Kenya, Somalia, Sudan, Tanzania, and Uganda. Its natural habitats are dry savanna and subtropical or tropical dry shrubland.
The Djibouti Xeric Shrublands ecoregion is a semi-desert strip on or near the Red Sea and the Gulf of Aden coasts in Eritrea, Ethiopia, Djibouti and Somalia. This ecoregion lies mainly between sea level and 800 meters (m) elevation. There are, however, many hills and massifs, which range up to 1300 m as well as outstanding fault-induced depressions, such as the Danakil, lying as low as 155 m below sea level. This region is extremely active tectonically, experiencing many earthquakes and intermittently active volcanoes. Rainfall is very low and yearly averages range from 100 to 200 millimeters (mm), with less rain falling closer to the coast. There are many species of interest, including the endemic Archer's lark, a species of dragon tree, and a large suite of desert ungulates, including the last viable population of African wild ass.
The Grand Bara, Bara Wein or Bada Wein, is a desert in southern Djibouti. It consists of large areas of sand flats, with sparse, semi-desert and desert grasses and scrub vegetation. A road built in 1981 passes through the area, connecting the capital Djibouti City with the south. Prior to the arrival of the French, the extremely arid interior was inhabited primarily by the Issa Somali. Runners make their way across the Grand Bara Desert during the Annual Grand Bara 15K race.
