Mountains Of Central Asia
The Mountains of Central Asia are a biodiversity hot spot designated by Conservation International which covers several montane and alpine ecoregions of Central Asia, including those of the Pamir and Tian Shan ranges, and extending across portions of Afghanistan, China, Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan and the Karakoram range in China, Pakistan and India. The Karakoram range is also famously known for Karakoram Anomaly that relates to the anomalous growth of glaciers in the central Karakoram that is in contrast with melting glaciers in other mountainous ranges of Himalayas and other parts of the world due to the effects of climate change. The hotspot encompasses several habitat types, including montane grasslands and shrublands, temperate coniferous forests, and alpine tundra. The ecoregions in the hotspot include: * Alai-Western Tian Shan steppe * Gissaro-Alai open woodlands * Pamir alpine desert and tundra * Tian Shan montane steppe and meadows The Tian Shan m ...

Geography Of Central Asia
Geography (from Greek: , ''geographia''. Combination of Greek words ‘Geo’ (The Earth) and ‘Graphien’ (to describe), literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. The first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. One such concept, the first law of geography, proposed by Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." Geography has been called "the world discipline" and "the bridge between the human and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecoregions Of Asia
An ecoregion (ecological region) or ecozone (ecological zone) is an 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 communities and species. The biodiversity of flora, 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. Ecoregions reflect the best compromise for as many taxa as possible. Sec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tian Shan Montane Conifer Forests
The Tian Shan montane conifer forests ecoregion (WWF ID: PA0521) covers the "forest belt" of the Tian Shan mountains - generally the north-facing slopes that get enough moisture, and are warm enough, for trees to grow. This conifer belt is found mostly between 1,500 and 2,700 meters. Location and description The ecoregion stretches in patches on the main Tian Shan mountain ridge, across approximately 2,000 km from western Kyrgyzstan to eastern Xinjiang Province in China. The conifer forest belt is found on north-facing slopes, at altitudes from a minimum of 1,500 meters (below which it is too dry to support conifers) to a maximum of 2,700 meters (above which it is too cold). The disconnected components of the ecoregion tend to be elongated along ridges that average 4,000 meters in height, with one of the larger sections wrapping around Lake Issyk-Kul. In general, the landscape below the forest belt is steppe, and above is alpine meadow with occasional dwarf junipers. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tian Shan Montane Steppe And Meadows
The Tian Shan montane steppe and meadows ecoregion (WWF ID: PA1019) covers a 2,000 km long stretch of grasslands of the isolated Tian Sham mountains of Central Asia. It is characterized by high-altitude flat and rolling grasslands. Location and description The ecoregion stretches around the lower altitudes of the Tian Shan mountain ridge, running for approximately 2,000 km from western Kyrgyzstan to eastern Xinjiang Province in China. It separates the arid Tarim Basin and Taklimakan Desert to the south from the Junggar Basin and Kazakh Shield to the north. Running up the middle of the ecoregion is the main ridge of the Tian Shan, with some middle altitudes supporting conifer forests in the Tian Shan montane conifer forests ecoregion. Climate The climate of the ecoregion is '' cold semi-arid'' (Köppen climate classification (BSk)). This climate is generally characterized as having precipitation greater than a true desert, and also a colder temperature. Flora and fauna ...

Pamir Alpine Desert And Tundra
The Pamir alpine desert and tundra ecoregion (WWF ID: PA1014) covers the high plateau of the Pamir Mountains, at the central meeting of the great mountain ranges of Central Asia: Himalaya, Karakoram, Hindu Kush, Kunlun, and Tian Shan. It is a region of relatively high biodiversity due to its central location and high elevation differentials, but it also acts as a barrier between the climate and habitats of north and south Asia. Location and description The ecoregion is mostly located in the eastern region of Tajikistan, on a high plateau with broad valleys and steeply-sloping mountains. The ecoregion measures about 275 km west-to-east, and 250 km north-to-south. Major mountain ranges radiate outwards: the Tian Shan to the northeast, Hindu Kush to the west, Karakoram to the south and Himalyas to the south and east. The Pamir also sit in the middle of different climates and habitats: the Alai woodlands to the west and north, and the dry Tarim Basin to the east. Th ...

Alpine Tundra
Alpine tundra is a type of natural region or biome that does not contain trees because it is at high elevation, with an associated harsh climate. As the latitude of a location approaches the poles, the threshold elevation for alpine tundra gets lower until it reaches sea level, and alpine tundra merges with polar tundra. The high elevation causes an adverse climate, which is too cold and windy to support tree growth. Alpine tundra transitions to sub-alpine forests below the tree line; stunted forests occurring at the forest-tundra ecotone are known as '' Krummholz''. With increasing elevation it ends at the snow line where snow and ice persist through summer. Alpine tundra occurs in mountains worldwide. The flora of the alpine tundra is characterized by dwarf shrubs close to the ground. The cold climate of the alpine tundra is caused by adiabatic cooling of air, and is similar to polar climate. Geography Alpine tundra occurs at high enough altitude at any latitude. Por ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temperate Coniferous Forests
Temperate coniferous forest is a terrestrial biome defined by the World Wide Fund for Nature. Temperate coniferous forests are found predominantly in areas with warm summers and cool winters, and vary in their kinds of plant life. In some, needleleaf trees dominate, while others are home primarily to broadleaf evergreen trees or a mix of both tree types. A separate habitat type, the tropical coniferous forests, occurs in more tropical climates. Temperate coniferous forests are common in the coastal areas of regions that have mild winters and heavy rainfall, or inland in drier climates or montane areas. Many species of trees inhabit these forests including pine, cedar, fir, and redwood. The understory also contains a wide variety of herbaceous and shrub species. Temperate coniferous forests sustain the highest levels of biomass in any terrestrial ecosystem and are notable for trees of massive proportions in temperate rainforest regions. Structurally, these forests are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montane Grasslands And Shrublands
Montane grasslands and shrublands is a biome defined by the World Wildlife Fund. The biome includes high elevation grasslands and shrublands around the world. The term "montane" in the name of the biome refers to "high elevation", rather than the ecological term which denotes the region below treeline. This biome includes high elevation ( montane and alpine) grasslands and shrublands, including the puna and páramo in South America, subalpine heath in New Guinea and East Africa, steppes of the Tibetan plateaus, as well as other similar subalpine habitats around the world. The plants and animals of tropical montane páramos display striking adaptations to cool, wet conditions and intense sunlight. Around the world, characteristic plants of these habitats display features such as rosette structures, waxy surfaces, and abundant pilosity. The páramos of the northern Andes are the most extensive examples of this habitat type. Although ecoregion biotas are most diverse in the An ...
