Small Mouse-tailed Bat
The small mouse-tailed bat (''Rhinopoma muscatellum'') is a species of bat in the Rhinopomatidae family. It is found in Afghanistan, Iran, Oman, and possibly Ethiopia, ranging from the Sistan Basin in Iran well into the Helmand River The Helmand river (Pashto/Dari: ; Ancient Greek: Ἐτύμανδρος, ''Etýmandros''; Latin: '), also spelled Helmend, or Helmund, Hirmand, is the longest river in Afghanistan and the primary watershed for the endorheic Sistan Basin. It o ... basin of south-western Afghanistan. Small mouse tailed bats have a wingspan of , a body length of and a tail the same length as its body. Their diet consists of flying insects which they eat whilst flying. This species was demonstrated as distinct from ''R. hardwickei'' based on mutually exclusive morphological features; the small mouse-tailed bat has a nearly unridged skull with small teeth and large cavities filled with fluid. Distance to roads-railways, annual mean temperature, elevation, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oldfield Thomas
Michael Rogers Oldfield Thomas (21 February 1858 – 16 June 1929) was a British zoologist. Career Thomas worked at the Natural History Museum, London, Natural History Museum on mammals, describing about 2,000 new species and subspecies for the first time. He was appointed to the museum secretary's office in 1876, transferring to the zoological department in 1878. In 1891, Thomas married Mary Kane, daughter of Sir Andrew Clark, 1st Baronet, Sir Andrew Clark, heiress to a small fortune, which gave him the finances to hire mammal collectors and present their specimens to the museum. He also did field work himself in Western Europe and South America. His wife shared his interest in natural history, and accompanied him on collecting trips. In 1896, when William Henry Flower took control of the department, he hired Richard Lydekker to rearrange the exhibitions, allowing Thomas to concentrate on these new specimens. Thomas viewed his taxonomy efforts from the scope of British impe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sistan Basin
The Sistan Basin is an inland endorheic basin encompassing large parts of southwestern Afghanistan and minor parts of southeastern Iran. It is one of the driest regions in the world and an area subject to prolonged droughts. Its watershed is a system of rivers flowing from the highlands of Afghanistan into freshwater lakes and marshes and then to its ultimate destination: Afghanistan's saline Godzareh Depression, part of the extensive Sistan terminal basin. The Helmand River drains the basin's largest watershed, fed mainly by snowmelt from the mountains of Hindu Kush, but other rivers contribute also. A basalt hill, known as Mount Khajeh, rises beside the lakes and marshes of the basin. Lakes The lowest part of the Sistan Basin contains a series of shallow lakes, known as '' hamuns''. It appears that in the past there was a single Hamun Lake, but there are now three separate lakes. From north to south the lakes are: Hamun-e Puzak The Hamun-e Puzak lies mostly in Af ...

Helmand River
The Helmand river (Pashto/Dari: ; Ancient Greek: Ἐτύμανδρος, ''Etýmandros''; Latin: '), also spelled Helmend, or Helmund, Hirmand, is the longest river in Afghanistan and the primary watershed for the endorheic Sistan Basin. It originates in the Sanglakh Range of the Hindu Kush mountains in the northeastern part of Maidan Wardak Province, where it is separated from the watershed of the Kabul River by the Unai Pass. The Helmand feeds into the Hamun Lake on the border of Afghanistan and Iran. Etymology The name comes from the Avestan ''Haētumant'', literally "dammed, having a dam", which referred to the Helmand River and the irrigated areas around it. The word Haetumant is cognate with Sanskrit Setumatī meaning "one which has a dam." Geography The Helmand stretches for . It rises in the northeastern part of Maidan Wardak Province in the Hindu Kush mountains, about 40 km west of Kabul (), flowing southwestward through Daykundi Province and Uruzga ...

Mammals Of Afghanistan
This list of the mammal species in Afghanistan provides information about the status of the 129 mammal species occurring in Afghanistan. Four are endangered, twelve are vulnerable, and five are near threatened. The following classes, which lie on a spectrum of lowest to highest risk of extinction, are used to highlight each species' global conservation status as assessed on the IUCN Red List: Order: Artiodactyla (even-toed ungulates) The even-toed ungulates are ungulates whose weight is borne about equally by the third and fourth toes, rather than mostly or entirely by the third as in perissodactyls. There are about 220 artiodactyl species, including many that are of great economic importance to humans. *Family: Bovidae (cattle, antelope, sheep, goats) **Subfamily: Antilopinae ***Genus: '' Gazella'' **** Chinkara, ''G. bennettii'' **** Goitered gazelle, ''G. subgutturosa'' ***Genus: '' Capra'' ****Wild goat, ''C. aegagrus'' presence uncertain **** Markhor, ''C. falconeri'' * ...

Mammals Described In 1903
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), c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Taxonomy Articles Created By Polbot
280px, Generalized scheme of taxonomy Taxonomy is a practice and science concerned with classification or categorization. Typically, there are two parts to it: the development of an underlying scheme of classes (a taxonomy) and the allocation of things to the classes (classification). Originally, taxonomy referred only to the classification of organisms on the basis of shared characteristics. Today it also has a more general sense. It may refer to the classification of things or concepts, as well as to the principles underlying such work. Thus a taxonomy can be used to organize species, documents, videos or anything else. A taxonomy organizes taxonomic units known as "taxa" (singular "taxon"). Many are hierarchies. One function of a taxonomy is to help users more easily find what they are searching for. This may be effected in ways that include a library classification system and a search engine taxonomy. Etymology The word was coined in 1813 by the Swiss botanist A ...

Taxa Named By Oldfield Thomas
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] |
