Karl Fedorovich Kessler
Karl Fedorovich Kessler (; – ) was a Baltic German zoologist who worked as a professor of biology at Saint Petersburg Imperial University. Among his contributions was the idea that evolution at an infraspecific level involved mutual aid and that Charles Darwin had placed too much emphasis on competition which he accepted as occurring at the interspecies level. Life and work Kessler was born in Damrau, Königsberg, Konigsberg, where his father was a royal forester (''oberforestmeister''). His father moved to Novgorod Governorate, where Kessler grew up. In 1828, he joined the with a scholarship and went to Saint Petersburg Imperial University in 1834. He attended the zoology lectures of Stepan Kutorga. After graduation he worked as a school mathematics teacher. In 1837, Kessler and his botanist friend from student days, went on an expedition to Finland. In 1840, he defended a master's dissertation on the legs of birds in relation to systematics. In 1842, his doctoral di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kyrgyzstan
Kyrgyzstan, officially the Kyrgyz Republic, is a landlocked country in Central Asia lying in the Tian Shan and Pamir Mountains, Pamir mountain ranges.

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called '' lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the 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 between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they dominate the subphylum Vertebrata, and constitute nearly 99% of the over 30,000 extant ...

Triplophysa
''Triplophysa'' is a genus of fish in the family Nemacheilidae found mainly in and around the Qinghai-Tibet Plateau in China, as well as inland waters of the larger part of central Asia. They can be distinguished from other genera of Nemacheilidae by marked sexual dimorphism, including the development of nuptial tubercles on breeding males. Currently, the genus is a mixed assemblage of species. Some lineages have been identified and treated as subgenera ('' Hedinichthys'', '' Indotriplophysa'', '' Labiatophysa'', '' Qinghaichthys'' and '' Tarimichthys''), but as Wikipedia follows Fishbase for fish species all but ''Hedinichthys'' have been treated as subgenera in Wikipedia, although Kottelat in his revision of the loaches did recognise them as valid. FishBase, however, includes these in ''Triplophysa'' without specifying subgenera and treats the names given by Kottelat as synonyms. Ecology '' Triplophysa zhaoi'' holds the record for the lowest altitude for Asian fish: it is fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Balkhash
Lake Balkhash, also spelt Lake Balqash (, , ), is a lake in southeastern Kazakhstan, one of the largest lakes in Asia and the 15th largest in the world. It is located in the eastern part of Central Asia and sits in the Balkhash-Alakol Basin, an endorheic (closed) basin. The basin drains seven rivers, the primary of which is the Ili, bringing most of the riparian inflow; others, such as the Karatal, bring surface and subsurface flow. The Ili is fed by precipitation, largely vernal snowmelt, from the mountains of China's Xinjiang region. The lake currently covers about . However, like the Aral Sea, it is shrinking due to diversion and extraction of water from its feeders. The lake has a narrow, quite central, strait. The lake's western part is fresh water and its eastern half is saline. The eastern part is on average 1.7 times deeper than the west. The largest shore city is named Balkhash and has about 66,000 inhabitants. Main local economic activities include mining, ore p ...

Issyk-Kul
Issyk-Kul () or Ysyk-Köl (, ; ) is an endorheic saline lake in the western Tianshan Mountains in eastern Kyrgyzstan, just south of a dividing range separating Kyrgyzstan from Kazakhstan. It is the eighth-deepest lake in the world, the eleventh-largest lake in the world by volume (though not in surface area), the deepest lake whose deepest point is above sea level (939 meters or 3,080 feet), and the third-largest saline lake. Although it is located at a lofty elevation of and subject to severe cold during winter, it rarely freezes over due to high salinity, hence its name, which in the Kyrgyz language means "warm lake". The lake is a Ramsar site of globally significant biodiversity and forms part of the Issyk-Kul Biosphere Reserve. Geography Issyk-Kul Lake is long, up to wide and its surface area is . It is the second-largest mountain lake in the world behind Lake Titicaca in South America. It is at an altitude of and reaches in depth. About 118 rivers and streams f ...

Lake Sasykkol
Sasykkol (, ''Sasyqköl'') is a lake in eastern Kazakhstan. It is located near . It has a surface area of 600 km2 (736 km2 when water level is high), average depth of 3.3 m, and maximum depth of 4.7 m. Fishery on the lake is common. Water birds including the mute swan, whooper swan, and spoonbill can be found here. Description Into the Sasykkol lake (translated from the Kazakh language "Sasyk" - rotten, fetid;" Kol " - lake), in the delta of the Alakol Biosphere Reserve, flows the Tentek river from the south. The average depth of the lake is about 3 m, and the maximum depth is 4.7 m. The average annual water level varies up to 60 cm due to the fact that the lake is flowing. Through the river Zhinishkesu water goes to Lake Koshkarkol and then flows into Lake Alakol. Since the water in the lake is fresh, its mineralization varies during the year from 0.27 to 2.16 g/L. Lake Sasykkol is part of the Alakol Biosphere Reserve, designated by UNESCO as part of its Man and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Alakol
Alakol Lake (, , from Turkic "motley lake") is a lake located in the Balkhash-Alakol Basin, part of the Abai Region, Abai and Jetisu Region, Jetisu regions, in east-central Kazakhstan. Its elevation is above sea level. The lake is the northwest extension of the region known as the Dzhungarian Gate (Alataw Pass), a narrow valley that connects the southern uplands of Kazakhstan with arid northwest China. The Dzhungarian Gate is a fault-bounded valley (see vertical line on the image along the southwest side of the lake) where the elevation of the valley floor is between 350 and 450 m above sea level and the peaks of the Dzhungarsky Alatau range (lower left) reach above sea level. Two well-defined alluvial fans are visible where mountain streams cut through the faulted landscape to the southwest of the lake. Its waters are reputed to have medicinal properties since the time of the Silk Road. In 2021, Lake Alakol was selected as one of the top 10 Tourist attraction, tourist destin ...

Lake Zaysan
Lake Zaysan or Zaisan, also known by other names in other languages, is a freshwater lake in Tarbagatay District, East Kazakhstan Region, Kazakhstan. It is the largest lake in the region. The lake is generally frozen from the beginning of November to the end of April, but still has an abundance of fish. The lake has been drying in the modern era, but that process has been stabilized by the construction of the Bukhtarma Hydroelectric Power Plant, of whose reservoir it's now a part. Names The Kazakh name of the lake is ''Zaisan kölı'' ( or ), pronounced . It derives from the Mongolian ''Zaisan nuur'' (), meaning "Noble Lake". Aside from its own nobility in size and beauty, it was used as the headquarters for various hordes and khanates, including the Dzungar Khanate. In the language of the local Dungan people, it is ''Jesonpe'' or ''Zhaisaonpe'' (). In Russian, it is ''Ozero Zajsan'' () and, in Chinese, ''Zhāisāng Pō'' Geography The lake lies at an altitude o ...

Fish Of Central Asia
A fish (: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are cold-blooded, their body temperature varying with the surrounding water, though some large active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communicate acoustically with each other, such as during courtship displays. The study of fish is known as ichthyology. The earliest fish appeared during the Cambrian as small filter feeders; they continued to evolve through the Paleozoic, diversifying into many forms. The earliest fish wi ...

Freshwater Fish Of China
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. The term excludes seawater and brackish water, but it does include non-salty mineral-rich waters, such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of vascular plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water is the water resource that is of the most and immediate use to humans. Fresh water is not always po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
