Üüreg Lake
Üüreg Lake (, , ''Üüreg nuur'', zh, 乌雷格湖) is a saline lake in an endorheic basin in Sagil, Uvs Province, Mongolia, north-west of the Great Lakes Hollow, near the western edge of the Uvs Nuur basin. The Tsagaan river gorge (''Tsagaan Shuvuut Uul'') lies on the west side of the lake. Geography The shores of the lake are slightly sloping and smooth, without bays or peninsulas. Several rivers flow into the lake, but most are intermittent. The largest river with a constant flow is the Khari River, which flows into the northwest of the lake. Swamp-type shrubs and swamps grow near the mouth of the Khari River. The lake water is salty due to high evaporation and no outflow. The Üüreg Lake depression is a desert, so there is a lot of evaporation from the water surface. The average annual evaporation is 800-900 mm. In addition to the inflow of rivers, this water loss is offset by rainfall and groundwater. The general salinity of the water is 4.17 g/L. Flora and fa ...

Mongolia
Mongolia is a landlocked country in East Asia, bordered by Russia to the north and China to the south and southeast. It covers an area of , with a population of 3.5 million, making it the world's List of countries and dependencies by population density, most sparsely populated sovereign state. Mongolia is the world's largest landlocked country that does not border an Endorheic basin, inland sea, and much of its area is covered by grassy steppe, with mountains to the north and west and the Gobi Desert to the south. Ulaanbaatar, the capital and List of cities in Mongolia, largest city, is home to roughly half of the country's population. The territory of modern-day Mongolia has been ruled by various nomadic empires, including the Xiongnu, the Xianbei, the Rouran, the First Turkic Khaganate, the Second Turkic Khaganate, the Uyghur Khaganate and others. In 1206, Genghis Khan founded the Mongol Empire, which became the largest List of largest empires, contiguous land empire i ...

Corsac Fox
The corsac fox (''Vulpes corsac''), also known simply as a corsac, is a medium-sized fox found in steppes, semi-deserts and deserts in Central Asia, ranging into Mongolia and northern China. Since 2004, it has been classified as ''least concern'' by IUCN, but populations fluctuate significantly, and numbers can drop tenfold within a single year. It is also known as the steppe fox. The word "corsac" is derived from the Russian name for the animal, ''"korsák"'' (корса́к), derived ultimately from Turkic "karsak". Description The Corsac fox is a medium-sized fox, with a head and body length of , and a tail long. Adults weigh from . It has grey to yellowish fur over much of the body, with paler underparts and pale markings on the mouth, chin, and throat. During the winter, the coat becomes much thicker and silkier in texture, and is straw-grey in colour, with a darker line running down the back. For a fox, it has small teeth and a wide skull.

Lakes Of Uvs Province
A lake is often a naturally occurring, relatively large and fixed body of water on or near the Earth's surface. It is localized in a depression (geology), basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by rivers. Lakes, as with other bodies of water, are part of the water cycle, the processes by which water moves around the Earth. Most lakes are fresh water and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume of water. Lakes are typically larger and deeper than ponds, which are also water-filled basins on land, although there are no official definitions or scientific criteria distinguishing the two. Lakes are also distinct from lagoons, which are generally shallow tidal pools dammed by sandbars or other material at coastal regions ...

Endorheic Lakes Of Asia
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 lakes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Important Bird Areas Of Mongolia
Importance is a property of entities that matter or make a difference. For example, World War II was an important event and Albert Einstein was an important person because of how they affected the world. There are disagreements in the academic literature about what type of difference is required. According to the causal impact view, something is important if it has a big causal impact on the world. This view is rejected by various theorists, who insist that an additional aspect is required: that the impact in question makes a value difference. This is often understood in terms of how the important thing affects the well-being of people. So in this view, World War II was important, not just because it brought about many wide-ranging changes but because these changes had severe negative impacts on the well-being of the people involved. The difference in question is usually understood counterfactually as the contrast between how the world is and how the world would have been witho ...

Carp
The term carp (: carp) is a generic common name for numerous species of freshwater fish from the family (biology), family Cyprinidae, a very large clade of ray-finned fish mostly native to Eurasia. While carp are prized game fish, quarries and are valued (even pisciculture, commercially cultivated) as both food fish, food and ornamental fish in many parts of the Old World, they are considered trash fish and invasive species, invasive pest (organism), pests in many parts of Africa, Australia and most of the United States. Biology The cypriniformes (family Cyprinidae) are traditionally grouped with the Characiformes, Siluriformes, and Gymnotiformes to create the superorder Ostariophysi, since these groups share some common features. These features include being found predominantly in fresh water and possessing Weberian ossicles, an anatomical structure derived from the first five anterior-most vertebrae, and their corresponding ribs and neural crests. The third anterior-most pair ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thymallus
''Thymallus'', commonly known as graylings, is a genus of freshwater ray-finned fish and the only genus within the subfamily Thymallinae of the family Salmonidae. Although all ''Thymallus'' species can be generically called graylings, without specific qualification the term "grayling" typically refers to the type species '' Thymallus thymallus'', the European grayling. Name The name of the genus ''Thymallus'' first given to grayling (''T. thymallus'') described in the 1758 edition of ''Systema Naturae'' by Swedish zoologist Carl Linnaeus originates from the faint smell of the herb thyme, which emanates from the flesh. ''Thymallus'' derives from the Greek θύμαλλος, "thyme smell". Species According to FishBase, 14 species are placed in this genus. However, views differ on their taxonomic rank. * '' Thymallus arcticus'' ( Pallas, 1776) - Arctic grayling * '' Thymallus baicalensis'' Dybowski, 1874 - Baikal black grayling * '' Thymallus brevipinnis'' Svetovid ...

Thymallus Brevirostris
The Mongolian grayling (''Thymallus brevirostris'') is a freshwater species of fish of the genus ''Thymallus'' endemic to the landlocked rivers in Mongolia, Inner Mongolia Province of China and nearby parts of Russian far east. It is considered to be the largest grayling species in the world, and hence viewed as an auspicious sign by local tribes. Description Mongolian grayling grow to a recorded maximum length of 65 cm (26 inches). The dorsal side is blackish, and the abdominal side is light. Black spots are uniformly present on both sides of the body. In adults, their upper jaw extends at least below the posterior edge of the eye. The Mongolian grayling is considered by researchers to be a relic from the Tertiary period. Distribution The Mongolian grayling is native to the landlocked lake region of Mongolia and the nearby Russian and Chinese areas, such as Khovd River, Issyk-Kul Lake and other rivers and lakes of the Altai Mountains, with Arctic graylings and their hybrids o ...

Mongolian Gull
The Mongolian gull (''Larus mongolicus'') is a large gull in the Larus, large white-headed gull (''Larus'') complex which breeds in interior eastern Asia. Taxonomy The Mongolian gull was species description, formally described in 1925 by the Russian ornithologist Petr Sushkin based on specimens collected near the Üüreg Lake in northwest Mongolia. He considered it to be a subspecies of the then broad view of the herring gull and coined the trinomial name ''Larus argentatus mongolicus''. When the herring gull was split into multiple more closely defined species, this Mongolian population was subsequently considered to be a subspecies of either the Vega gull (''Larus vegae'') from further north in northeastern Siberia, or of the Caspian gull (''Larus cachinnans'') from further west. In 2024 it was raised to separate species rank based on its distinct morphology and vocal repertoire. Description Mongolian gull is closely similar to its relatives Caspian gull and Vega gull, and al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anseriformes
Anseriformes is an order (biology), order of birds also known as waterfowl that comprises about 180 living species of birds in three families: Anhimidae (three species of screamers), Anseranatidae (the magpie goose), and Anatidae, the largest family, which includes over 170 species of waterfowl, among them the ducks, goose, geese, and swans. Most modern species in the order are highly adapted for an aquatic existence at the water surface. With the exception of screamers, males have Penis#Birds, penises, a trait that has been lost in the Neoaves, the clade consisting of all other modern birds except the galliformes and paleognaths. Due to their aquatic nature, most species are web-footed. Evolution Anseriformes are one of only two types of modern bird to be confirmed present during the Mesozoic alongside the other dinosaurs, and in fact were among the very few birds to survive their extinction, along with their cousins, the Galliformes. These two groups only occupied two ecologic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mongolian Ground Jay
The Mongolian ground jay (''Podoces hendersoni'') or Henderson's ground jay, is a species of bird in the family Corvidae. Description The bird is light tan with iridescent blue on its primary feathers. It has a long, curved beak and a black stripe on its forehead. Distribution It is found in arid areas of Central Asia (Mongolia, northern China and adjacent areas of Russia and Kazakhstan). It is threatened by habitat loss and fragmentation. It tends to live on areas with gravel surfaces. Behaviour Eggs are typically laid and hatched in April-May. They nest in ''Prunus pedunculata''. Females spend more time foraging and the males spend more time brooding the chicks at the start of the nesting period. They are most active in the morning. Among ground jays, they have a relatively short trill call. Diet The main diet of the nestling Mongolian ground jay consists of common lizards, toad-headed agama, and invertebrates Invertebrates are animals that neither develop nor retai ...

Desman
Desmans are aquatic insectivores of the tribe Desmanini (also considered a subfamily, Desmaninae) in the mole (animal), mole family, Talpidae. This tribe consists of two living species found in Europe: the Russian desman (''Desmana moschata'') in European Russia, and the Pyrenean desman (''Galemys pyrenaicus'') in the northwest of the Iberian Peninsula and the Pyrenees. Both species are Endangered species, endangered, the Russian desman Critically Endangered, critically so. They have webbed paws and their front paws are not well-adapted for digging. Desmans were much more diverse and widespread during the Miocene, with two genera, ''Gaillardia (mole), Gaillardia'' and ''Magnatalpa'', being present in North America. Both living species are thought to have derived from the fossil genus ''Archaeodesmana.''
