Torey Lakes
The Torey Lakes are a pair of soda lakes, Barun-Torey and Zun-Torey, in Russia's Zabaykalsky Krai, on the border with Mongolia (Coordinates 50°04'N, 115°31'E). Geography and hydrography The lakes lie close to one another and are connected by a channel. They are in a closed basin with no outlet to the sea. The size and volume of water in the lakes varies with the region's multi-decadal rainfall and climate cycles.Yu, Afonina & A., Tashlykova. (2018). Planktonic Communities in the Torey Lakes (Zabaikalsky Krai) in a Low Water Year. Journal of Siberian Federal University. Biology. 11. 306-320. 10.17516/1997-1389-0074. Barun-Torey During high-water years, Lake Barun-Torey has an area of 550 km², with a volume of 1.4 km3. The average depth is 2.5 m, and the maximum depth is 4.3 m. In low-water years the lake shrinks dramatically, and can dry up completely. The southern end of the lake extends into Mongolia. Lake Barun-Torey is fed by two rivers. The Ulz or Uldza River (Uldza-Gol) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endorheic
An endorheic basin (; also spelled endoreic basin or endorreic basin) is a drainage basin that normally retains water and allows no outflow to other external bodies of water, such as rivers or oceans, but drainage converges instead into lakes or swamps, permanent or seasonal, that equilibrate through evaporation. They are also called closed or terminal basins, internal drainage systems, or simply basins. Endorheic regions contrast with open and closed lakes, exorheic regions. Endorheic water bodies include some of the largest lakes in the world, such as the Caspian Sea, the world's largest inland body of water. Basins with subsurface outflows which eventually lead to the ocean are generally not considered endorheic; they are cryptorheic. Endorheic basins constitute local base levels, defining a limit of erosion and deposition processes of nearby areas. Etymology The term was borrowed from French ''endor(rh)éisme'', coined from the combining form ''endo-'' (from grc, ἔν ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Relict Gull
The relict gull or Central Asian gull (''Ichthyaetus relictus'') is a medium-sized gull. It was believed to be an eastern race of the Mediterranean gull until 1971 and was traditionally placed in the genus ''Larus''. Description The gull is 44 to 45 cm long with a stocky, thick body. Non-breeding adults feature uniformly dark-smudged ear-coverts and hind crown, white-tipped wings, prominent, isolated black subterminal markings on outer primaries, and no white leading edge to outer wing. Breeding birds have black hoods (including napes) with grey-brown foreheads, and broad, white, half-moon colouring behind, below, and above their eyes. Their legs are orange and their bills scarlet. The name comes from its status as a relict species.Ming Ma, Ying Chen, Kedeerhan Bayahen, Baowen Hu, Fei Li, Jiaqing Wu, Xiang Gao, Yu Mei"Seasonal changes in the number of Relict Gull (''Larus relictus'') at Ebinur Lake, Western China" ''Journal of Arid Land'', 2010, volume 2, number 2, pp 15 ...

Lakes Of Zabaykalsky Krai
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UNESCO World Heritage
A World Heritage Site is a landmark or area with legal protection by an international convention administered by the United Nations Educational, Scientific and Cultural Organization (UNESCO). World Heritage Sites are designated by UNESCO for having cultural, historical, scientific or other form of significance. The sites are judged to contain "cultural and natural heritage around the world considered to be of outstanding value to humanity". To be selected, a World Heritage Site must be a somehow unique landmark which is geographically and historically identifiable and has special cultural or physical significance. For example, World Heritage Sites might be ancient ruins or historical structures, buildings, cities, deserts, forests, islands, lakes, monuments, mountains, or wilderness areas. A World Heritage Site may signify a remarkable accomplishment of humanity, and serve as evidence of our intellectual history on the planet, or it might be a place of great natural beauty. As ...

Daursky Nature Reserve
The Daurian Nature Reserve (Даурский заповедник ''Daurskiy zapavyednik'') is a Russian 'zapovednik' (strict nature reserve) situated in the southern part of the Zabaykalsky Krai in Siberia, Russia, close to the border with Mongolia. It is part of a World Heritage Site named "The Landscapes of Dauria". The reserve has been established in 1987 to protect the dry steppes and wetlands of South Siberia. It is contiguous with the Dornod Mongol Biosphere Reserve in Mongolia, a area of steppe immediately to the south. The reserve comprises 222,965.00 ha, of which about 173,201.00 ha constitute the buffer zone. The core area is of about 49,764.00 ha and is divided into 9 plots. The buffer zone of the reserve covers the Torey Lakes, two large lakes called Barun-Torey and Zun-Torey. Ecoregion and climate The Daurian Reserve is located in the Daurian forest steppe ecoregion, a band of grassland, shrub terrain, and mixed forests in northeast Mongolia and a portion of Sib ...

Hooded Crane
The hooded crane (''Grus monacha'') is a crane native to East Asia and a frequent migratory bird in Japan. Description It has a grey body. The top of the neck and head is white, except for a patch of bare red skin above the eye. It is one of the smallest cranes, but is still a fairly large bird, at 1 m (3.3 ft) long, a weight of 3.7 kg (8.2 lbs) and a wingspan of 1.87 m (6.2 ft). Distribution The hooded crane breeds in south-central and south-eastern Siberia. Breeding is also suspected to occur in Mongolia. Over 80% of its population winters at Izumi, southern Japan. There are also wintering grounds in South Korea and China. There are about 100 hooded cranes wintering in Chongming Dongtan, Shanghai every year. Dongtan Nature Reserve is the largest natural wintering site in the world. In December 2011, a hooded crane was seen overwintering at the Hiwassee Refuge in southeastern Tennessee, well outside its normal range. In February 2012, one was s ...

Siberian Crane
The Siberian crane (''Leucogeranus leucogeranus''), also known as the Siberian white crane or the snow crane, is a bird of the family Gruidae, the cranes. They are distinctive among the cranes: adults are nearly all snowy white, except for their black primary feathers that are visible in flight, and with two breeding populations in the Arctic tundra of western and eastern Russia. The eastern populations migrate during winter to China, while the western population winters in Iran and (formerly) in Bharatpur, India. Among the cranes, they make the longest distance migrations. Their populations, particularly those in the western range, have declined drastically in the 20th century due to hunting along their migration routes and habitat degradation. The world population was estimated in 2010 at about 3,200 birds, mostly belonging to the eastern population with about 95% of them wintering in the Poyang Lake basin in China, a habitat that may be altered by the Three Gorges Dam.

East Asian–Australasian Flyway
The East Asian–Australasian Flyway is one of the world's great flyways. At its northernmost it stretches eastwards from the Taimyr Peninsula in Russia to Alaska. Its southern end encompasses Australia and New Zealand. Between these extremes the Flyway covers much of eastern Asia, including China, Japan, Korea, South-East Asia and the western Pacific. The EAAF is home to over 50 million migratory water birds from over 250 different populations, including 32 globally threatened species and 19 near threatened species. It is especially important for the millions of migratory waders or shorebirds that breed in northern Asia and Alaska and spend the non-breeding season in South-East Asia and Australasia. Flyway Site Network During migration, water birds rely on a system of highly productive wetlands to rest and feed, building up sufficient energy to fuel the next phase of their journey. International cooperation across their migratory range is therefore essential to conserve and pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Bustard
The great bustard (''Otis tarda'') is a bird in the bustard family, the only member of the genus ''Otis''. It breeds in open grasslands and farmland from northern Morocco, South and Central Europe, to temperate Central and East Asia. European populations are mainly resident, but Asian populations migrate farther south in winter. It has been listed as Vulnerable on the IUCN Red List since 1996. Portugal and Spain now have about 60% of the world's population. It became extinct in Great Britain when the last bird was shot in 1832. Recent attempts to reintroduce it into England have met with some success and there is a population of 40 birds on Salisbury Plain, a British Army training area. Here the lack of public access allows them the freedom needed as a large ground-nesting bird. Taxonomy and etymology The genus ''Otis'' was introduced in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. Linnaeus placed four species in the genus but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soda Lake
A soda lake or alkaline lake is a lake on the strongly alkaline side of neutrality, typically with a pH value between 9 and 12. They are characterized by high concentrations of carbonate salts, typically sodium carbonate (and related salt complexes), giving rise to their alkalinity. In addition, many soda lakes also contain high concentrations of sodium chloride and other dissolved salts, making them saline or hypersaline lakes as well. High pH and salinity often coincide, because of how soda lakes develop. The resulting hypersaline and highly alkalic soda lakes are considered some of the most extreme aquatic environments on Earth.Grant, W. D. (2006). ''Alkaline environments and biodiversity.'' in ''Extremophiles'', 2006, UNESCO / Eolss Publishers, Oxford, UK In spite of their apparent inhospitability, soda lakes are often highly productive ecosystems, compared to their (pH-neutral) freshwater counterparts.

Swan Goose
The swan goose (''Anser cygnoides'') is a large goose with a natural breeding range in inland Mongolia, northernmost China, and the Russian Far East. It is migratory and winters mainly in central and eastern China. Vagrant birds are encountered in Japan and Korea (where it used to winter in numbers when it was more common), and more rarely in Kazakhstan, Laos, coastal Siberia, Taiwan, Thailand and Uzbekistan. While uncommon in the wild, this species has been domesticated. Introduced and feral populations of its domestic breeds occur in many places outside its natural range. The wild form is also kept in collections, and escapes are not unusual amongst feral flocks of other ''Anser'' and ''Branta'' geese. Description The swan goose is large and long-necked for its genus, wild birds being long (the longest ''Anser'' goose) and weighing or more (the second-heaviest ''Anser'', after the greylag goose, ''A. anser''). The sexes are similar, although the male is larger, with a prop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
