Jaculus (rodent)
The genus ''Jaculus'' is a member of the Dipodinae subfamily of dipodoid rodents (jerboas). ''Jaculus'' species are distributed in desert and semi-arid regions across northern Africa, the Sahara, the Horn of Africa, Arabia, the Middle East, and Central Asia. Collectively, the species within the genus may be commonly referred to as "desert jerboas", although this more particularly applied to the lesser Egyptian jerboa (''Jaculus jaculus'').Myers ''et al.'' (2006). Species The following species are recognised for the genus ''Jaculus'': * Blanford's jerboa, ''Jaculus blanfordi'' * Lesser Egyptian jerboa, ''Jaculus jaculus'' * Greater Egyptian jerboa, ''Jaculus orientalis'' * Thaler's jerboa ''Jaculus thaleri'' * African hammada jerboa ''Jaculus hirtipes'' References Sources * Holden, M.

Miocene
The Miocene ( ) is the first epoch (geology), geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene followed the Oligocene and preceded the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and Ape, hominoids into Eurasia. During the late Miocene, the conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arabia
The Arabian Peninsula (, , or , , ) or Arabia, is a peninsula in West Asia, situated north-east of Africa on the Arabian plate. At , comparable in size to India, the Arabian Peninsula is the largest peninsula in the world. Geographically, the Arabian Peninsula comprises Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, the United Arab Emirates (UAE) and Yemen, as well as southern Iraq and Jordan. The largest of these is Saudi Arabia. In the Roman era, the Sinai Peninsula was also considered a part of Arabia. The Arabian Peninsula formed as a result of the rifting of the Red Sea between 56 and 23 million years ago, and is bordered by the Red Sea to the west and south-west, the Persian Gulf and the Gulf of Oman to the north-east, the Levant and Mesopotamia to the north and the Arabian Sea and the Indian Ocean to the south-east. The peninsula plays a critical geopolitical role in the Arab world and globally due to its vast reserves of petroleum, oil and natural gas. Before the mod ...

Taxa Named By Johann Christian Polycarp Erxleben
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Of West Asia
A mammal () is a vertebrate animal of the class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors diverged in the Carboniferous Period over 300 million years ago. Around 6,640 extant species of mammals have been described and divided into 27 orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including cats, dogs, and seals). Mammals are the only living members of Synapsida; this clade, together with Sauropsida (reptiles and birds), constitutes the larger ...

Dipodidae
Jerboas () are the members of the family Dipodidae. They are hopping desert rodents found throughout North Africa and Asia. They tend to live in hot deserts. When chased, jerboas can run at up to . Some species are preyed on by little owls (''Athene noctua'') in central Asia. Most species of jerboas have excellent hearing that they use to avoid becoming the prey of nocturnal predators. The typical lifespan of a jerboa is around 2–3 years. Taxonomy Jerboas, as previously defined, were thought to be paraphyletic, with the jumping mice ( Zapodidae) and birch mice (Sminthidae) also being classified in the family Dipodidae. However, phylogenetic analysis split all three as distinct families, leaving just the jerboas in Dipodidae and revealing them to be a monophyletic group. This animal has a body length (including the head) of between , with an additional of tail, which is always longer than the full body. Jerboa dental records reveal a slow increase in crown heights, which c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Greater Egyptian Jerboa
The greater Egyptian jerboa (''Jaculus orientalis'') is a species of rodent in the family Dipodidae. It is found in Algeria, Egypt, Libya, Morocco, Saudi Arabia, Tunisia, and is possibly extinct in the Negev Desert of Israel. Its natural habitats are subtropical or tropical dry shrubland, sandy shores, and arable land. Description An adult greater Egyptian jerboa has a head-and-body length of about and a tail of . The upper parts are yellowish-brown or sandy-brown and the underparts are white. The hind legs are very large and are about four times longer than the forelimbs. The feet have hairy pads which improves locomotion on sand. The tail is nearly naked but ends in a large tuft of hair which is black at the base and white at the tip. The tail is used as a prop to stabilise the animal when it stands and moves on its hind legs. Distribution and habitat On the African continent, the greater Egyptian jerboa is found in Morocco, Algeria, Tunisia, Libya and Egypt. It is also presen ...

Lesser Egyptian Jerboa
The lesser jerboa (''Jaculus jaculus'') is a small rodent of Africa and the Middle East. Its diet consists mainly of seeds and grasses. Description A small rodent, it is sometimes likened to a tiny kangaroo due to its incredibly large hind legs, and hopping form of locomotion. The lesser Egyptian jerboa has three toes on each of its hind feet and a very long tail, used for balance when jumping. It has large eyes and ears and a rather stubby snout, and its coat is a pale or dark sandy colour with a paler underside. Biology The lesser Egyptian jerboa is a strictly nocturnal species, feeding on seeds, insects, succulent parts of desert grasses, and fungi (desert truffles ''Terfezia'' species), which it detects using its acute sense of smell. Amazingly, it does not need to drink in order to survive the arid desert conditions, relying on its food to provide it with all its water needs. The lesser Egyptian jerboa can travel long distances in search of food, up to ten kilometres a d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blanford's Jerboa
Blanford's jerboa (''Jaculus blanfordi'') is a species of rodent in the family Dipodidae. It is native to Central Asia and is found in Turkmenistan, Uzbekistan, Afghanistan, Iran and Pakistan. Taxonomy Blanford's jerboa was first described in 1884 by the British zoologist James Albert Murray, curator of the Karachi Museum and author of a number of books on the birds and mammals of the Indian subcontinent. He named it "''Jaculus blanfordi''" in honour of the British geologist and zoologist William Thomas Blanford who was a member of the Indian Geological Survey and later published works on the fauna of India. Distribution and habitat Blanford's jerboa is native to Central Asia. Its range extends from Turkmenistan and Iran, through the Kyzyl Kum Desert and Karakum Desert to central Uzbekistan, Afghanistan and southwestern Pakistan. Its typical habitat is bare clayey or gravelly areas in deserts and other arid localities, but not sandy areas with dunes. Behaviour Blanford's jerb ...
