Chevrotain
Chevrotains, or mouse-deer, are small, even-toed ungulates that make up the family Tragulidae, and are the only living members of the infraorder Tragulina. The 10 extant species are placed in three genera, but several species also are known only from fossils. The extant species are found in forests in South and Southeast Asia; a single species, the water chevrotain, is found in the rainforests of Central and West Africa. In November 2019, conservation scientists announced that they had photographed silver-backed chevrotains (''Tragulus versicolor'') in a Vietnamese forest for the first time since the last confirmed sightings in 1990. They are solitary, or live in loose groupings or pairs, and feed almost exclusively on plant material. Chevrotains are the smallest hoofed mammals in the world. The Asian species weigh between , while the African chevrotain is considerably larger, at . With an average length of and an average height of , the Java mouse-deer is the ...

Water Chevrotain
The water chevrotain (''Hyemoschus aquaticus''), also known as the fanged deer, is a small ruminant found in tropical Africa. This is the only species in the genus ''Hyemoschus''. It is the largest of the 10 species of chevrotains, basal even-toed ungulates which are visually similar to deer, but are barely larger than small dogs. Description Unusually for most mammals, female water chevrotains are larger than males. On average, they weigh over 2 kg more than the 10-kg males. Their body length is about 85 cm, and their shoulder height is around 35 cm. Water chevrotains have a rich, sleek, red-brown coat on top, and the underside of the coat is white. On the body is a pattern of white stripes that runs horizontally from the shoulder to the tail, with vertical rows of white stripes in the back. The chin, throat, and chest are covered in very coarse hair with a pattern of white V shapes. The back end of the water chevrotain has many powerful muscles and is higher ...

Tragulus Versicolor
The Vietnam mouse-deer (''Tragulus versicolor''), also known as the silver-backed chevrotain, is an even-toed ungulate in the family Tragulidae known only from Vietnam. It was first described in 1910 by British zoologist Oldfield Thomas, who procured four specimens from Nha Trang in Annam. Little is known about its distribution and ecology. After 1910, the Vietnam mouse-deer was reported next in 1990 near Dak Rong and Buon Luoi in the Gia Lai Province. With increasing hunting pressure, habitat loss due to deforestation and no more reports of the species in the wild, the mouse-deer was feared to have gone extinct. The IUCN listed the species as Data Deficient in 2008. In 2019, a study confirmed the presence of the Vietnam mouse-deer in dry low-lying forests of southern Vietnam with camera trap evidence. The mouse-deer is characterised by a rough coat with a strange double-tone coloration unseen in other chevrotains; the front part of the body is reddish brown and contrasts stro ...

Sri Lankan Spotted Chevrotain
''Moschiola meminna'' is a species of even-toed ungulate in the chevrotain family (Tragulidae). Particularly in the old literature, ''M. meminna'' often refers to the spotted chevrotains as a whole. Today, the name is increasingly restricted to the Sri Lankan spotted chevrotain or white-spotted chevrotain, with the Indian spotted chevrotain ''M. indica'' and/or the yellow-striped chevrotain ''M. kathygre'' treated as distinct species. In Sri Lanka Sri Lanka, officially the Democratic Socialist Republic of Sri Lanka, also known historically as Ceylon, is an island country in South Asia. It lies in the Indian Ocean, southwest of the Bay of Bengal, separated from the Indian subcontinent, ..., this species is found in the dry zone and is replaced in the wet zone by the yellow-striped chevrotain. Description Head and body length in the species typically is 55–60 cm. It is dull brown in color with three or four dotted white stripes going longitudinally along fla ...

Indian Spotted Chevrotain
The Indian spotted chevrotain (''Moschiola indica'') is a species of even-toed ungulate in the family Tragulidae. It is native to India and possibly Nepal Nepal, officially the Federal Democratic Republic of Nepal, is a landlocked country in South Asia. It is mainly situated in the Himalayas, but also includes parts of the Indo-Gangetic Plain. It borders the Tibet Autonomous Region of China Ch .... It lives in rainforests and is nocturnal. It has a body length of with a long tail length and weighs around . This was earlier included under the name of ''Tragulus meminna'', but studies on the systematics of the group have led to that name being restricted to the Sri Lankan spotted chevrotain.

Moschiola
''Moschiola'', the spotted chevrotains, are a genus of small even-toed ungulates in the family Tragulidae. They are found in forests in India, Sri Lanka and perhaps Nepal, and have pale-spotted or -striped upperparts unlike the other Asian members of the family, the mouse-deer of the genus '' Tragulus''.Nowak, R. M. (eds) (1999). ''Walker's Mammals of the World.'' 6th edition. Johns Hopkins University Press. In former times, the genus was usually treated as monotypic. Described as ''Moschus meminna'', for most of the time the name ''Tragulus meminna'' was used, but changed to ''Moschiola meminna'' eventually. In the 21st century, this is increasingly divided into up to three parapatric species A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction.

Java Mouse-deer
The Java mouse-deer (''Tragulus javanicus'') is a species of even-toed ungulate in the family Tragulidae. When it reaches maturity it is about the size of a rabbit, making it the smallest living ungulate. It is found in forests in Java and perhaps Bali, although sightings there have not been verified. This mouse-deer is depicted in Indonesian folklore as '' Sang Kancil''. Nomenclature The Java mouse-deer has many common names, including Javan chevrotain, Javan mousdeer, or Java Mouse Deer.Facts about Lesser Mouse Deer (Tragulus javanicus) - Encyclopedia of Life.

Tragulina
Tragulina (also known as Traguliformes) is an infraorder of even-toed ungulates. Only the chevrotains survive to the present, including the genera ''Tragulus'' (the mouse deer) and '' Hyemoschus'', all within the family Tragulidae. Taxonomy and classification Tragulina is an infraorder within the larger suborder Ruminantia, and is the sister clade to the infraorder Pecora. Tragulina contains one extant (living) family, Tragulidae, as well as several extinct families, although the extinct members currently classified as within Tragulina causes it to be considered paraphyletic. Tragulina's placement within Artiodactyla can be represented in the following cladogram:(see e.g. Fig S10) The following is the taxonomy of the group Tragulina. *Infrarorder TRAGULINA **† Praetragulidae ***'' Praetragulus'' ***'' Parvitragulus'' ***'' Simimeryx'' **† Archaeomerycidae ***'' Archaeomeryx'' ***'' Miomeryx'' ***'' Paukkaungmeryx'' **† Gelocidae ***'' Phaneromeryx'' ***'' Paragelocu ...

Even-toed Ungulate
Artiodactyls are placental mammals belonging to the order Artiodactyla ( , ). Typically, they are ungulates which bear weight equally on two (an even number) of their five toes (the third and fourth, often in the form of a hoof). The other three toes are either present, absent, vestigial, or pointing posteriorly. By contrast, most perissodactyls bear weight on an odd number of the five toes. Another difference between the two orders is that many artiodactyls (except for Suina) digest plant cellulose in one or more stomach chambers rather than in their intestine (as perissodactyls do). Molecular biology, along with new fossil discoveries, has found that cetaceans (whales, dolphins, and porpoises) fall within this taxonomic branch, being most closely related to hippopotamuses. Some modern taxonomists thus apply the name Cetartiodactyla () to this group, while others opt to include cetaceans within the existing name of Artiodactyla. Some researchers use "even-toed ungulates" to e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruminant
Ruminants are herbivorous grazing or browsing artiodactyls belonging to the suborder Ruminantia that are able to acquire nutrients from plant-based food by fermenting it in a specialized stomach prior to digestion, principally through microbial actions. The process, which takes place in the front part of the digestive system and therefore is called foregut fermentation, typically requires the fermented ingesta (known as cud) to be regurgitated and chewed again. The process of rechewing the cud to further break down plant matter and stimulate digestion is called rumination. The word "ruminant" comes from the Latin ''ruminare'', which means "to chew over again". The roughly 200 species of ruminants include both domestic and wild species. Ruminating mammals include cattle, all domesticated and wild bovines, goats, sheep, giraffes, deer, gazelles, and antelopes.Fowler, M.E.

Omasum
The omasum, also known as the green, the fardel, the manyplies and the psalterium, is the third compartment of the stomach in ruminants. The omasum comes after the rumen and reticulum and before the abomasum. Different ruminants have different omasum structures and function based on the food that they eat and how they developed through evolution. Anatomy The omasum can be found on the right side of the cranial portion of the rumen. It receives food from the reticulum through the reticulo-omasal orifice and provides food to the abomasum through the omaso-abomasal orifice. The omasum is spherical to crescent shape and has multiple leaflets similar to that of a book called omasal laminae. The omasal laminae are made of thin muscular layers covered with a nonglandular mucous membrane. The omasal laminae come from the sides of the large curvature and project towards the inside of the omasum, extending from the reticulo-omasal orifice to the omaso-abomasal orifice. They greatly incre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carotid Rete
A heat exchanger is a system used to transfer heat between a source and a working fluid. Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural-gas processing, and sewage treatment. The classic example of a heat exchanger is found in an internal combustion engine in which a circulating fluid known as engine coolant flows through radiator coils and air flows past the coils, which cools the coolant and heats the incoming air. Another example is the heat sink, which is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant. Flow arrangement There are three primary classifications of heat exchangers according to their flow arrange ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
