Alashan Plateau Semi-desert
The Alashan Plateau semi-desert'' ecoregion (WWF ID: PA1302) covers the south-western portion of the Gobi Desert where precipitation in the mountains is sufficient for a short part of the summer to support sparse plant life. The terrain is basin and range, with elevations from . The region straddles the China-Mongolian border, with the Tibetan Plateau to the south, and the more arid regions of the Gobi to the north and east. Location and description The ecoregion encompasses the desert basins and low mountains bordered by the Lop Desert on the west, the Tibetan Plateau and Qilian Mountains to the south, the Gobi extension of the Altai Mountains on the north, and the Helan Mountains to the southeast. This part of the Gobi desert is in the rain shadow of the Tibetan Plateau. However, parts of it still receive enough precipitation to support areas of semi-arid desert plant communities. Climate The climate of the ecoregion is a cool arid climate (Köppen ''BWk''). This climate i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 W ...

Haloxylon Ammodendron
''Haloxylon ammodendron'', the saxaul, black saxaul, sometimes sacsaoul or saksaul ( rus, саксау́л, r=saksaúl, which is from kk, сексеуіл, r=seksewil), is a plant belonging to the family Amaranthaceae. Description The saxaul ranges in size from a large shrub to a small tree, , rarely tall. It has a brown trunk up to in diameter. The wood is heavy and coarse and the bark is spongy and water-soaked. The branches of the current year are green; older branches are brown, or gray to white. The leaves are reduced to very small cusp-like scales, so that the plant appears nearly leafless. The infloresences consist of short lateral shoots borne on stems of the previous year. The flowers are bisexual or male, very small, as long as or shorter than the bracteoles. The flowering period is from March to April. In fruit, the perianth segments develop spreading pale brown or white wings. The diameter of the winged fruit is about . The seed is in diameter.

Gobi Gurvansaikhan National Park
Gobi Gurvansaikhan National Park (, ''Gobi three beauties nature complex'') is a national park in southern Mongolia. The park was established in 1993, and expanded to its current size in 2000. The park, at nearly 27,000 square kilometers, is the largest national park in Mongolia, stretching 380 km from east to west and 80 km from north to south. The park is named for the Gurvan Saikhan Mountains, which translates to the ''Three Beauties''. The name is derived from three subranges, the East, Middle and West Beauty. The range forms the eastern half of the park. The park lies on the northern edge of the Gobi desert. The higher elevations contain areas of steppe, and reach elevations of up to 2,600 meters. A number of rare plants and animals are found in the park, including the elusive snow leopard and the Gobi camel. Areas of sand dunes are found, most famously the Khongoryn Els - the Singing Sands. Another major tourist destination is Yolyn Am, which is conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tamarix
The genus ''Tamarix'' (tamarisk, salt cedar, taray) is composed of about 50–60 species of flowering plants in the family Tamaricaceae, native to drier areas of Eurasia and Africa. The generic name originated in Latin and may refer to the Tamaris River in Hispania Tarraconensis (Spain). Description They are evergreen or deciduous shrubs or trees growing to in height and forming dense thickets. The largest, ''Tamarix aphylla'', is an evergreen tree that can grow to tall. They usually grow on saline soils, tolerating up to 15,000 ppm soluble salt, and can also tolerate alkaline conditions. Tamarisks are characterized by slender branches and grey-green foliage. The bark of young branches is smooth and reddish brown. As the plants age, the bark becomes gray-brown, ridged and furrowed. The leaves are scale-like, almost like that of junipers, 1–2 mm (1/20" to 1/10") long, and overlap each other along the stem. They are often encrusted with salt secretions. The pink ...

Yellow River
The Yellow River or Huang He (Chinese: , Mandarin: ''Huáng hé'' ) is the second-longest river in China, after the Yangtze River, and the sixth-longest river system in the world at the estimated length of . Originating in the Bayan Har Mountains in Qinghai province of Western China, it flows through nine provinces, and it empties into the Bohai Sea near the city of Dongying in Shandong province. The Yellow River basin has an east–west extent of about and a north–south extent of about . Its total drainage area is about . The Yellow River's basin was the birthplace of ancient Chinese, and, by extension, Far Eastern civilization, and it was the most prosperous region in early Chinese history. There are frequent devastating floods and course changes produced by the continual elevation of the river bed, sometimes above the level of its surrounding farm fields.

Calligonum Mongolicum
''Calligonum'' is a genus of plants in the family Polygonaceae with about 80 species across the Mediterranean Sea region, Asia and North America. Description Plants of the genus ''Calligonum'' are shrubs, diffusely but irregularly branched, with flexuous woody branches. Leaves are simple, opposite, nearly sessile, linear or scale-like, sometimes absent or very small, linear or filiform, distinct or united with short membranous ochreae. Flowers are bisexual, solitary or in loose axillary inflorescences. Flowers have persistent, 5-parted perianths not accrescent in fruit, and 10-18 stamens with filaments connate at the base. The ovary is tetragonous. Taxonomy The genus ''Calligonum'' was first published by Carl Linnaeus in 1753. It is placed in the subfamily Polygonoideae, tribe Calligoneae, along with its sister genus, '' Pteropyrum''.

Zygophyllum
''Zygophyllum'' is the type genus of the flowering plant family Zygophyllaceae. The generic name is derived from the Greek words ζυγόν (''zygon''), meaning "double", and φυλλον (''phyllon''), meaning "leaf". It refers to the leaves, each of which have two leaflets. The genus is distributed in arid and semi-arid regions of Africa, the Mediterranean Basin, central Asia Central Asia, also known as Middle Asia, is a subregion, region of Asia that stretches from the Caspian Sea in the west to western China and Mongolia in the east, and from Afghanistan and Iran in the south to Russia in the north. It includes t ... and Australia. Molecular phylogenetic analysis suggested that as previously circumscribed, ''Zygophyllum'' was not monophyletic, and the genus was split among a number of other genera, including '' Augea'', '' Fagonia'', '' Roepera'' and '' Tetraena''.
