John McClelland (doctor)
John McClelland or M'Clelland (1805 – 31 July 1883) was a British medical doctor with interests in natural history, who worked for the East India Company in India and Burma. He served as a temporary curator of the museum of the Asiatic Society of Bengal just before a permanent curator was found in Edward Blyth. McClelland is thought to have been born in Ireland, studied medicine and was admitted member of the Royal College of Surgeons in 1828. He entered the service of the East India Company in the Bengal Medical Service on 7th April 1830. In 1835 he was sent on a mission (Tea Committee) to identify if tea could be grown in north-eastern India along with Nathaniel Wallich and William Griffith. This mission ran into troubles with the members of the group clashing with each other. McClelland was appointed 1836 as the secretary of the "Coal Committee", the forerunner of the Geological Survey of India (GSI), formed to explore possibilities to exploit Indian coal.

Actinopterygii
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class (biology), class of Osteichthyes, bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fish fin, fins made of webbings of skin supported by radially extended thin bony spine (zoology), spines called ''lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister taxon, sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation (anatomy), articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they domi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Cyprinidae
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family, including the carps, the true minnows, and their relatives the barbs and barbels, among others. Cyprinidae is the largest and most diverse fish family, and the largest vertebrate animal family overall, with about 1,780 species divided into 166 valid genera. Cyprinids range from about in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless, or ''agastric'', fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used to identify spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Asia
Central Asia is a region of Asia consisting of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. The countries as a group are also colloquially referred to as the "-stans" as all have names ending with the Persian language, Persian suffix "-stan" (meaning ) in both respective native languages and most other languages. The region is bounded by the Caspian Sea to the southwest, European Russia to the northwest, China and Mongolia to the east, Afghanistan and Iran to the south, and Siberia to the north. Together, the five Central Asian countries have a total population of around million. In the pre-Islamic and early Islamic eras ( and earlier) Central Asia was inhabited predominantly by Iranian peoples, populated by Eastern Iranian-speaking Bactrians, Sogdians, Khwarezmian language, Chorasmians, and the semi-nomadic Scythians and Dahae. As the result of Turkic migration, Central Asia also became the homeland for the Kazakhs, Kyrgyzs, Volga Tatars, Tatars, Turkmens, ...

Syr Darya
The Syr Darya ( ),; ; ; ; ; /. historically known as the Jaxartes ( , ), is a river in Central Asia. The name, which is Persian language, Persian, literally means ''Syr Sea'' or ''Syr River''. It originates in the Tian Shan, Tian Shan Mountains in Kyrgyzstan and eastern Uzbekistan and flows for west and north-west through Uzbekistan, Sughd province of Tajikistan, and southern Kazakhstan to the North Aral Sea, northern remnants of the Aral Sea. It is the northern and eastern of the two main rivers in the endorheic basin of the Aral Sea, the other being the Amu Darya. In the Soviet Union, Soviet era, extensive irrigation projects were constructed around both rivers, diverting their water into farmland and causing, during the post-Soviet era, the virtual disappearance of the Aral Sea, once the world's fourth-largest lake. The point at which the river flows from Tajikistan into Uzbekistan is, at above sea level, the lowest elevation in Tajikistan. Name The second part of the nam ...

Amu Darya
The Amu Darya ( ),() also shortened to Amu and historically known as the Oxus ( ), is a major river in Central Asia, which flows through Tajikistan, Turkmenistan, Uzbekistan, and Afghanistan. Rising in the Pamir Mountains, north of the Hindu Kush, the Amu Darya is formed by the confluence of the Vakhsh River, Vakhsh and Panj River, Panj rivers, in the Tigrovaya Balka Nature Reserve on the border between Afghanistan and Tajikistan, and flows from there north-westwards into the South Aral Sea, southern remnants of the Aral Sea. In its upper course, the river forms part of Afghanistan's northern border with Tajikistan, Uzbekistan, and Turkmenistan. In ancient history, the river was regarded as the boundary of Greater Iran with Turan, which roughly corresponded to present-day Central Asia.B. SpulerĀmū Daryā in Encyclopædia Iranica, online ed., 2009 The Amu Darya has a flow of about 70 cubic kilometres per year on average. Names In classical antiquity, the river was known as the ...

Talas River
The Talas (; Kyrgyz and ) is a river that rises in the Talas Region of Kyrgyzstan and flows west into Kazakhstan. The river is long and has a basin area of . Course It is formed from the confluence of the Karakol and the Uch-Koshoy and flows roughly west and northwest. It runs through the city of Taraz in Zhambyl Province of Kazakhstan and vanishes in the Muyunkum Desert before reaching Lake Aydyn. The Ili, Chu and Talas are three steppe rivers that flow west and then north-west. The Ili rises in Xinjiang, flows west to a point north of Lake Issyk Kul and then turns north-west to reach Lake Balkash. The Chu rises west of Lake Issyk Kul, flows out into the steppe and dries up before reaching the Syr Darya. The Talas starts west and south of the Chu, flows west and north-west, but dries up before reaching the Chu. History During the Battle of Talas (named after the river) in 751, the Abbasid force defeated the Tang Chinese forces led by the General Gao Xianzhi over ...

Endorheic Basin
An endorheic basin ( ; also endoreic basin and endorreic basin) is a drainage basin that normally retains water and allows no outflow to other external bodies of water (e.g. rivers and oceans); instead, the water drainage flows into permanent and seasonal lakes and swamps that equilibrate through evaporation. Endorheic basins are also called closed basins, terminal basins, and internal drainage systems. Endorheic regions contrast with open lakes (exorheic regions), where surface waters eventually drain into the ocean. In general, water basins with subsurface outflows that lead to the ocean are not considered endorheic; but cryptorheic. Endorheic basins constitute local base levels, defining a limit of the erosion and deposition processes of nearby areas. Endorheic water bodies include the Caspian Sea, which is the world's largest inland body of water. Etymology The term ''endorheic'' derives from the French word , which combines ( 'within') and 'flow'. Endorheic lake ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
