Great Lakes Basin Desert Steppe
The Great Lakes Basin desert steppe ecoregion (WWF ID: PA1316) covers the enclosed basin centered on Uvs Lake, a saline, endorheic basin (that is, no external drainage to the ocean) in northwestern Mongolia. A portion of the ecoregion stretches across the region into Russia. The lake district is important for migrating birds, waterfowl, and seabirds. The ecoregion is in the Palearctic realm and the deserts and xeric shrublands biome. It has an area of . Location and description The ecoregion stretches approximately 500 km west to east, and 600 km north to south, to encompass the Uvs Lake Basin in northwestern Mongolia and borderlands in Russia. Aside from the lakes, the terrain is gently sloping clay and gravel, mostly at elevations of 700 meters to 2,000 meters. The mountains on the margins reach up to above sea level. Intersperse are tracts of bare sand, bogs, and rock outcrops. Climate The climate of the ecoregion is cool semi-arid (Köppen climate classification ...

Palearctic
The Palearctic or Palaearctic is the largest of the eight biogeographic realms of the Earth. It stretches across all of Eurasia north of the foothills of the Himalayas, and North Africa. The realm consists of several bioregions: the Euro-Siberian region; the Mediterranean Basin; the Sahara and Arabian Deserts; and Western, Central and East Asia. The Palaearctic realm also has numerous rivers and lakes, forming several freshwater ecoregions. The term 'Palearctic' was first used in the 19th century, and is still in use as the basis for zoogeographic classification. History In an 1858 paper for the ''Proceedings of the Linnean Society'', British zoologist Philip Sclater first identified six terrestrial zoogeographic realms of the world: Palaearctic, Aethiopian/Afrotropic, Indian/Indomalayan, Australasian, Nearctic, and Neotropical. The six indicated general groupings of fauna, based on shared biogeography and large-scale geographic barriers to migration. Alfred Wallace a ...

Uvs Lake Basin
Uvs Lake Basin (also Uvs Nuur Basin or Ubs Nuur Basin; mn, Увс нуурын хотгор, Uws nuuriin hotgor) is an endorheic basin located on the territorial border of Mongolia and Tuva, a republic of the Russian Federation. The basin is part of the Central Asian Internal Drainage Basin and is named after Uvs Lake (Uvs Nuur, Ubsu Nur), a large saline lake situated in the western part of its drainage basin and is one of the last remnants of the mammoth steppes. Uvs Lake is a shallow lake with an area of . Its entire basin, which includes several smaller lakes, is . Uvs Lake Basin may also refer to Ubsunur Hollow (Russian: Убсунурская котловина, ''Ubsunorskaya Kotlovina''), which is the western part of the drainage basin, or to over of protected areas covering the lake and its surroundings. The hollow forms the northern part of the Great Lakes Depression, which has a surface of over . The hollow, and most of the drainage basin, are situated in the Khövsgö ...

Deserts And Xeric Shrublands
Deserts and xeric shrublands are a biome defined by the World Wide Fund for Nature. Deserts and xeric (ancient Greek xērós, “dry") shrublands form the largest terrestrial biome, covering 19% of Earth's land surface area. Ecoregions in this habitat type vary greatly in the amount of annual rainfall they receive, usually less than annually except in the margins. Generally evaporation exceeds rainfall in these ecoregions. Temperature variability is also diverse in these lands. Many deserts, such as the Sahara, are hot year-round, but others, such as East Asia's Gobi, become quite cold in winter. Temperature extremes are a characteristic of most deserts. High daytime temperatures give way to cold nights because there is no insulation provided by humidity and cloud cover. The diversity of climatic conditions, though quite harsh, supports a rich array of habitats. Many of these habitats are ephemeral in nature, reflecting the paucity and seasonality of available water.

Ecoregions Of Mongolia
An ecoregion (ecological region) or ecozone (ecological zone) is an ecology, ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural community (ecology), communities and species. The biodiversity of flora (plants), flora, fauna (animals), fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregion ...

Khar Us Nuur National Park
Har Us Nuur National Park ( mn, Хар Ус Нуур) covers a chain of three large lakes in the Great Lakes Basin of western Mongolia. The lakes, Khar-Us Nuur, Khar Lake and Dörgön Lake are bordered by marshes and reed-beds that are an important breeding sport for birds, over 200 species of which have been identified in the park. Mount Jargalant is on the southern shore of Khar-Us. This park is distinct from Khyargas Nuur National Park, another large lake in the region, but 60 km to the north. Topography The main lake is Khar-Us Nuur ("Black water lake"), 70 km at its longest extent. Khar-Us is fed by the Khovd Gol (River), which enters in a delta on the west side. In the north of the 1,852 km2 lake is a large island, Agbash ("White Head"), with an area of 274 km2. Immediately east of Khar-Us is Khar Lake ("Black Lake", 565 km2), which is connected by a canal with Dörgön Lake (300 km2) to the southeast. The first two lakes are freshwater, the third is salin ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Semi-arid Climate
A semi-arid climate, semi-desert climate, or steppe climate is a dry climate sub-type. It is located on regions that receive precipitation below potential evapotranspiration, but not as low as a desert climate. There are different kinds of semi-arid climates, depending on variables such as temperature, and they give rise to different biomes. Defining attributes of semi-arid climates A more precise definition is given by the Köppen climate classification, which treats steppe climates (''BSk'' and ''BSh'') as intermediates between desert climates (BW) and humid climates (A, C, D) in ecological characteristics and agricultural potential. Semi-arid climates tend to support short, thorny or scrubby vegetation and are usually dominated by either grasses or shrubs as it usually can't support forests. To determine if a location has a semi-arid climate, the precipitation threshold must first be determined. The method used to find the precipitation threshold (in millimeters): *multiply by ...
