North Tibetan Plateau–Kunlun Mountains Alpine Desert
The North Tibetan Plateau-Kunlun Mountains alpine desert ecoregion (WWF ID: PA1011) covers a long stretch of mostly treeless alpine terrain across the northern edge of the Tibet Plateau. A variety of cold, dry habitats are found, including alpine meadows, steppe, desert, and cushion plant floral areas. Location In the northwest, the ecoregion begins at the east edge of the Pamir Mountains, then covers the Kunlun Mountains in the north and the high plateau south to the Karakoram Mountains. From there it follows the Kunlun from west to east across the northern edge of the Tibet Plateau, on the south rim of the arid Tarim Basin. Elevations, higher in the northwest, are mostly above 5,000 meters, and the soils are often salty and barren. The region is dry, cold, and very remote. Permafrost lies under much of the territory. Much of the eastern extension is within the Altun Shan National Nature Reserve. Climate The climate of the ecoregion is ''Tundra climate'' (Köppen climate clas ...

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 ...

Tundra
In physical geography, tundra () is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. The term ''tundra'' comes through Russian (') from the Kildin Sámi word (') meaning "uplands", "treeless mountain tract". There are three regions and associated types of tundra: Arctic tundra, alpine tundra, and Antarctic tundra. Tundra vegetation is composed of dwarf shrubs, sedges, grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline. The tundra soil is rich in nitrogen and phosphorus. The soil also contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide in the permafrost, making the tundra soil a carbon sink. As global warming heats the ecosystem and causes soil thawing, the permafrost carbon cycle accelerates and releases much of these soil-contained g ...

Lagomorpha
The lagomorphs are the members of the taxonomic order Lagomorpha, of which there are two living families: the Leporidae (hares and rabbits) and the Ochotonidae (pikas). The name of the order is derived from the Ancient Greek ''lagos'' (λαγώς, "hare") + ''morphē'' (μορφή, "form"). There are 110 recent species of lagomorph of which 109 are extant, including 34 species of pika, 42 species of rabbit, and 33 species of hare. Taxonomy and evolutionary history Other names used for this order, now considered synonymous, include: ''Duplicidentata'' - Illiger, 1811; ''Leporida'' - Averianov, 1999; ''Neolagomorpha'' - Averianov, 1999; ''Ochotonida'' - Averianov, 1999; and ''Palarodentia'' - Haeckel, 1895, Lilian, 2016. The evolutionary history of the lagomorphs is still not well understood. Until recently, it was generally agreed that '' Eurymylus'', which lived in eastern Asia and dates back to the late Paleocene or early Eocene, was an ancestor of the lagomorphs. More re ...

Oxytropis
''Oxytropis'' is a genus of plants in the legume family. It is one of three genera of plants known as locoweeds, and are notorious for being toxic to grazing animals. The other locoweed genus is the closely related ''Astragalus''. There are about 600 species, native to Eurasia and North America. Several species are native to the Arctic. These are hairy perennial plants which produce raceme inflorescences of pink, purple, white, or yellow flowers which are generally pea-like but have distinctive sharply beaked keels. The stems are leafless, the leaves being all basal. The plant produces legume pods containing the seeds.

Stipa
''Stipa'' is a genus of around 300 large perennial hermaphroditic grasses collectively known as feather grass, needle grass, and spear grass. They are placed in the subfamily Pooideae and the tribe Stipeae, which also contains many species formerly assigned to ''Stipa'', which have since been reclassified into new genera. Many species are important forage crops. Several species such as ''Stipa brachytricha'', ''S. arundinacea'', ''S. splendens'', ''S. calamagrostis'', ''S. gigantea'' and ''S. pulchra'' are used as ornamental plants. One former species, esparto grass (''Macrochloa tenacissima''), is used for crafts and extensively in paper making. It is a coarse grass with inrolled leaves and a panicle patterned inflorescence. Ecology Species of the genus ''Stipa'' can occur in grasslands or in savanna habitats. Certain specific prairie plant associations are dominated by grasses of the genus ''Stipa'', which genus often lends its name to the terminology of some prairie types. ...

Carex
''Carex'' is a vast genus of more than 2,000 species of grass-like plants in the family Cyperaceae, commonly known as sedges (or seg, in older books). Other members of the family Cyperaceae are also called sedges, however those of genus ''Carex'' may be called true sedges, and it is the most species-rich genus in the family. The study of ''Carex'' is known as caricology. Description All species of ''Carex'' are perennial, although some species, such as '' C. bebbii'' and '' C. viridula'' can fruit in their first year of growth, and may not survive longer. They typically have rhizomes, stolons or short rootstocks, but some species grow in tufts (caespitose). The culm – the flower-bearing stalk – is unbranched and usually erect. It is usually distinctly triangular in section. The leaves of ''Carex'' comprise a blade, which extends away from the stalk, and a sheath, which encloses part of the stalk. The blade is normally long and flat, but may be folded, inrolled, c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Picea Schrenkiana
''Picea schrenkiana'', Schrenk's spruce, or Asian spruce, is a spruce native to the Tian Shan mountains of central Asia in western China (Xinjiang), Kazakhstan, and Kyrgyzstan. It grows at altitudes of 1,200–3,500 metres, usually in pure forests, sometimes mixed with the Tien Shan variety of Siberian fir (''Abies sibirica'' var. ''semenovii''). Its name was given in honour of Alexander von Schrenk (1816–1876). Description ''Picea schrenkiana'' is a large evergreen tree growing to tall (rarely to ), with a trunk diameter of up to . It has a narrow conical crown with level branches and sometimes pendulous branchlets. The shoots are pale buff-brown, and glabrous (hairless). The leaves are needle-like, 1.5–3.5 cm long, rhombic in cross-section, dark green with inconspicuous stomatal lines. The cones are cylindrical–conic, 6–12 cm long and 2 cm broad, purple when young, maturing dark brown and opening to 2.5–3.5 cm broad 5–7 months after pollinati ...

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] |
Altun Shan National Nature Reserve
Altun Shan National Nature Reserve () (literally, "O You Golden Mountain") is a large, arid area in the southeast of Xinjiang Autonomous Region, on the northern edge of the Tibetan plateau and the southern edge of the Tarim Basin in northwest China. It surrounds the Kumkol Basin, an endorheic basin (no outlets to the sea) in the western third of the Altyn-Tagh mountains ("Altun Shan"). The reserve is sometimes referred to as the "Arjin Mountains Nature Reserve", or "Aerjinshan". The reserve covers the southern portions of Qiemo County and Ruoqiang County (including Qimantag Township ()) of Bayingolin Mongol Autonomous Prefecture in Xinjiang. Topography The Altun Shan Reserve is an elongated triangular area on the southern edge of the Taklamakan Desert, just south of the Tarim Basin.
