Tarim Basin Deciduous Forests And Steppe
The Tarim Basin deciduous forests and steppe is a temperate broadleaf and mixed forests ecoregion in the Xinjiang, Xinjiang Uyghur Autonomous Region of western China. The ecoregion includes deciduous riparian forests and steppes sustained by the region's rivers in an otherwise arid region. Geography The Tarim Basin is a desert basin lying in westernmost China. The basin is surrounded by high mountains – the Kunlun Mountains to the south, which form the northern edge of the Tibetan Plateau; the Pamir Mountains to the west; and the Tian Shan to the north. The basin is arid, but the surrounding mountains receive considerable rainfall and snow. Rivers drain into the basin from the mountains, including the northward-flowing Hotan River, which drains the western Kunlun Mountains, the Yarkand River, which drains the Pamirs, and the Aksu River (Xinjiang), Aksu River, which drains the western Tian Shan mountains. These rivers join to form the Tarim River, which flows for 1300 km in an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palearctic Realm
The Palearctic or Palaearctic is a biogeographic realm of the Earth, the largest of eight. Confined almost entirely to the Eastern Hemisphere, it stretches across Europe and Asia, north of the foothills of the Himalayas, and North Africa. The realm consists of several bioregions: the Mediterranean Basin; North Africa; North Arabia; Western, Central and East Asia. The Palaearctic realm also has numerous rivers and lakes, forming several freshwater ecoregions. Both the eastern and westernmost extremes of the Paleartic span into the Western Hemisphere, including Cape Dezhnyov in Chukotka Autonomous Okrug to the east and Iceland to the west. The term 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/ Indom ...

Taitema Lake
Taitema Lake () is an endorheic lake in Ruoqiang County, Bayingolin Mongol Autonomous Prefecture, southeast of the Tarim Basin, Xinjiang Uyghur Autonomous Region, People's Republic of China. It is located in the northern part of Ruoqiang County, and is one of the three main depressions of that area, the other two being Karakoshun Lake (喀拉库顺湖) and Lop Nur. For about 1,500 years before 1921, the Tarim River poured into Taitema Lake from north, the Qiemo River from southwest, and the lake water overflowed southward into Karakoshun Lake and then entered Lop Nur from south. In 1959, the area of Taitema Lake was 183 square kilometers. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Populus Pruinosa

Halophyte
A halophyte is a salt-tolerant plant that grows in soil or waters of high salinity, coming into contact with saline water through its roots or by salt spray, such as in saline semi-deserts, mangrove swamps, marshes and sloughs, and seashores. The word derives from Ancient Greek ἅλας (halas) 'salt' and φυτόν (phyton) 'plant'. Halophytes have different anatomy, physiology and biochemistry than glycophytes.Physiology of halophytes, T. J. FLOWERS, Plant and Soil 89, 41–56 (1985) An example of a halophyte is the salt marsh grass '' Spartina alterniflora'' (smooth cordgrass). Relatively few plant species are halophytes—perhaps only 2% of all plant species. Information about many of the earth's halophytes can be found in thhalophytedatabase. The large majority of plant species are glycophytes, which are not salt-tolerant and are damaged fairly easily by high salinity. Classification Halophytes can be classified in many ways. According to Stocker (1933), it is mainly o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halostachys Caspica
''Halostachys'' is a genus of flowering plants in the plant family Amaranthaceae, containing a single species, ''Halostachys caspica''. The plants are small to medium halophytic shrubs with apparently jointed fleshy stems and scale-like leaves. They are native to western and central Asia and northern China. Description ''Halostachys caspica'' grows as a shrub to 1–3 m height and width. The erect stems are much branched, older twigs are mostly leafless. The young twigs are blue-green, fleshy, apparently jointed (articulated), with glabrous fine papillose surface. The opposite leaves are fleshy, glabrous, connate basally and surrounding the stem (thus forming the joints), with very short scale-like triangular blades. The inflorescences consist of numerous opposite lateral cylindrical spikes, 15-30 × 2–5 mm, on jointed peduncles. Groups of three bisexual flowers are sitting in the axils of rhombic-quadrate bracts. The opposite bracts are not connate to each other. The obov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tamarix Ramosissima

Populus Euphratica
''Populus'' is a genus of 25–30 species of deciduous flowering plants in the family Salicaceae, native to most of the Northern Hemisphere. English names variously applied to different species include poplar (), aspen, and cottonwood. The western balsam poplar ( ''P. trichocarpa'') was the first tree to have its full DNA code determined by DNA sequencing, in 2006. Description The genus has a large genetic diversity, and can grow from tall, with trunks up to in diameter. The bark on young trees is smooth and white to greenish or dark gray, and often has conspicuous lenticels; on old trees, it remains smooth in some species, but becomes rough and deeply fissured in others. The shoots are stout, with (unlike in the related willows) the terminal bud present. The leaves are spirally arranged, and vary in shape from triangular to circular or (rarely) lobed, and with a long petiole; in species in the sections ''Populus'' and ''Aigeiros'', the petioles are laterally flatt ...

Tugay
Tugay is a form of riparian forest or woodland associated with fluvial and floodplain areas in arid climates. These wetlands are subject to periodic inundation, and largely dependent on floods and groundwater rather than directly from rainfall. Tugay habitats occur in semi-arid and desert climates in Central Asia. Because Tugay habitat is usually linear, following the courses of rivers in arid landscapes, Tugay communities often function as wildlife corridors. They have disappeared or become fragmented over much of their former range. Distribution The centre of the range of Tugay vegetation is the Tarim Basin in north-western China, where the Tarim Huyanglin nature reserve in the middle reaches of the Tarim River holds the largest areas of intact Tugay forests, with a 1993 estimate of about 61% of the total. The Central Asian countries hold another 31%, with smaller areas remaining in the Middle East and Pakistan. Tugais also occur in the Caucasus. Vegetation Close to ...

Phragmites Australis
''Phragmites australis'', known as the common reed, is a species of flowering plant in the grass family Poaceae. It is a wetland grass that can grow up to tall and has a cosmopolitan distribution worldwide. Description ''Phragmites australis'' commonly forms extensive stands (known as reed beds), which may be as much as or more in extent. Where conditions are suitable it can also spread at or more per year by horizontal runners, which put down roots at regular intervals. It can grow in damp ground, in standing water up to or so deep, or even as a floating mat. The erect stems grow to tall, with the tallest plants growing in areas with hot summers and fertile growing conditions. The leaves are long and broad. The flowers are produced in late summer in a dense, dark purple panicle, about long. Later the numerous long, narrow, sharp pointed spikelets appear greyer due to the growth of long, silky hairs. These eventually help disperse the minute seeds. Taxonomy Recent stu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wet Meadow
A wet meadow is a type of wetland with soils that are Solubility, saturated for part or all of the growing season which prevents the growth of trees and brush. Debate exists whether a wet meadow is a type of marsh or a completely separate type of wetland. Wet prairies and wet savannas are hydrologically similar. Hydrology and ecology Wet meadows may occur because of restricted drainage or the receipt of large amounts of water from rain or melted snow. They may also occur in riparian zones and around the shores of large lakes. Unlike a marsh or swamp, a wet meadow does not have standing water present except for brief to moderate periods during the growing season. Instead, the ground in a wet meadow fluctuates between brief periods of Flood, inundation and longer periods of Hydric soil, saturation. Wet meadows often have large numbers of wetland plant species, which frequently survive as buried seeds during dry periods, and then regenerate after flooding. Wet meadows therefore do ...
