Temperate Grasslands, Savannas And Shrublands
Temperate grasslands, savannas, and shrublands is a terrestrial biome defined by the World Wide Fund for Nature. The predominant vegetation in this biome consists of grass and/or shrubs. The climate is temperate and ranges from semi-arid to semi-humid. The habitat type differs from tropical grasslands in the annual temperature regime as well as the types of species found here. The habitat type is known as prairie in North America, pampas in South America, veld in Southern Africa and steppe in Asia. Generally speaking, these regions are devoid of trees, except for riparian or gallery forests associated with streams and rivers. Steppes/shortgrass prairies are short grasslands that occur in semi-arid climates. Tallgrass prairies are tall grasslands in areas of higher rainfall. Heaths and pastures are, respectively, low shrublands and grasslands where forest growth is hindered by human activity but not the climate. Tall grasslands, including the tallgrass prairie of North America, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biome Map 08
A biome () is a biogeographical unit consisting of a biological community that has formed in response to the physical environment in which they are found and a shared regional climate. Biomes may span more than one continent. Biome is a broader term than habitat and can comprise a variety of habitats. While a biome can cover large areas, a microbiome is a mix of organisms that coexist in a defined space on a much smaller scale. For example, the human microbiome is the collection of bacteria, viruses, and other microorganisms that are present on or in a human body. A biota is the total collection of organisms of a geographic region or a time period, from local geographic scales and instantaneous temporal scales all the way up to whole-planet and whole-timescale spatiotemporal scales. The biotas of the Earth make up the biosphere. Etymology The term was suggested in 1916 by Clements, originally as a synonym for '' biotic community'' of Möbius (1877). Later, it gained its cu ...

Heath (habitat)
A heath () is a shrubland habitat found mainly on free-draining infertile, acidic soils and characterised by open, low-growing woody vegetation. Moorland is generally related to high-ground heaths with—especially in Great Britain—a cooler and damper climate. Heaths are widespread worldwide but are fast disappearing and considered a rare habitat in Europe. They form extensive and highly diverse communities across Australia in humid and sub-humid areas where fire regimes with recurring burning are required for the maintenance of the heathlands.Specht, R.L. 'Heathlands' in 'Australian Vegetation' R.H. Groves ed. Cambridge University Press 1988 Even more diverse though less widespread heath communities occur in Southern Africa. Extensive heath communities can also be found in the Texas chaparral, New Caledonia, central Chile, and along the shores of the Mediterranean Sea. In addition to these extensive heath areas, the vegetation type is also found in scattered locations ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Equus Hemionus
The onager (; ''Equus hemionus'' ), A new species called the kiang (''E. kiang''), a Tibetan relative, was previously considered to be a subspecies of the onager as ''E. hemionus kiang'', but recent molecular studies indicate it to be a distinct species, having diverged from the closest relative of the Mongolian wild ass's ancestor less than 500,000 years ago. Subspecies Five widely recognized subspecies of the onager include: A sixth possible subspecies, the Gobi khulan (''E. h. luteus'', also called the ''chigetai'' or ''dziggetai'') has been proposed, but may be synonymous with ''E. h. hemionus''. Debates over the taxonomic identity of the onager occurred until 1980. , four living subspecies and one extinct subspecies of the Asiatic wild ass have been recognized. The Persian onager was formerly known as ''Equus onager'', as it was thought to be a distinct species. Characteristics Onagers are the most horse-like of wild asses. They are short-legged compared to horses, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pantholops Hodgsoni
The Tibetan antelope or chiru (''Pantholops hodgsonii'') (, pronounced ; ) is a medium-sized bovid native to the northeastern Tibetan plateau. Most of the population live within the Chinese border, while some scatter across India and Bhutan in the high altitude plains, hill plateau and montane valley. Fewer than 150,000 mature individuals are left in the wild, but the population is currently thought to be increasing. In 1980s and 1990s, they had become endangered due to massive illegal poaching. They are hunted for their extremely soft, light and warm underfur which is usually obtained after death. This underfur, known as ''shahtoosh'' (a Persian word meaning "king of fine wools"), is used to weave luxury shawls. Shahtoosh shawls were traditionally given as wedding gifts in India and it takes the underfur of three to five adult antelopes to make one shawl. Despite strict controls on trade of shahtoosh products and CITES listing, there is still demand for these luxury items. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saiga Tatarica
The saiga antelope (, ''Saiga tatarica''), or saiga, is a critically endangered antelope which during antiquity inhabited a vast area of the Eurasian steppe spanning the foothills of the Carpathian Mountains in the northwest and Caucasus in the southwest into Mongolia in the northeast and Dzungaria in the southeast. During the Pleistocene, they also occurred in Beringian North America and the British Isles. Today, the dominant subspecies (''S. t. tatarica'') is only found in one region in Russia (in the Republic of Kalmykia and Astrakhan Oblast) and three areas in Kazakhstan (the Ural, Ustiurt, and Betpak-Dala populations). A portion of the Ustiurt population migrates south to Uzbekistan and occasionally Turkmenistan in winter. It is extirpated from China, Ukraine, and southwestern Mongolia. The Mongolian subspecies (''S. t. mongolica'') is found only in western Mongolia. Taxonomy and phylogeny The scientific name ''Capra tatarica'' was coined by Carl Linnaeus in 1766 in the ...

Bos Bison
The American bison (''Bison bison'') is a species of bison native to North America. Sometimes colloquially referred to as American buffalo or simply buffalo (a different clade of bovine), it is one of two extant species of bison, alongside the European bison. Its historical range, by 9000 BC, is described as the great bison belt, a tract of rich grassland that ran from Alaska to the Gulf of Mexico, east to the Atlantic Seaboard (nearly to the Atlantic tidewater in some areas) as far north as New York, south to Georgia and, according to some sources, further south to Florida, with sightings in North Carolina near Buffalo Ford on the Catawba River as late as 1750. Once roaming in vast herds, the species nearly became extinct by a combination of commercial hunting and slaughter in the 19th century and introduction of bovine diseases from domestic cattle. With a population in excess of 60 million in the late 18th century, the species was culled down to just 541 animals by 1889. Re ...

Agriculture
Agriculture or farming is the practice of cultivating plants and livestock. Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that enabled people to live in cities. The history of agriculture began thousands of years ago. After gathering wild grains beginning at least 105,000 years ago, nascent farmers began to plant them around 11,500 years ago. Sheep, goats, pigs and cattle were domesticated over 10,000 years ago. Plants were independently cultivated in at least 11 regions of the world. Industrial agriculture based on large-scale monoculture in the twentieth century came to dominate agricultural output, though about 2 billion people still depended on subsistence agriculture. The major agricultural products can be broadly grouped into foods, fibers, fuels, and raw materials (such as rubber). Food classes include cereals (grains), vegetables, fruits, cooking oils, meat, milk, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Humid Pampas
The Humid Pampas ( es, Pampa Húmeda) is an extensive ecoregion of flat, fertile grassland of loessic origin in Argentina. It has a precipitation average of 900 mm per year, in contrast with the Dry Pampas to the west, which average less than 700 mm. Setting Like the Pampas in general, the region's terrain is predominantly hilly and of a temperate climate, though rich mollisols are more abundant here than to the west, where soils of loessic origin are more common. Except for a few bluffs near the Paraná and Río de la Plata rivers, as well as the Tandilia and Ventania mountain ranges to the south, the region's slope rarely exceeds 6 degrees. It covers Buenos Aires Province almost completely, the centre and south of Santa Fe Province, most of Córdoba Province and the eastern third of La Pampa Province, totalling at least 600,000 km². The Uruguayan savanna, which lies east of the rivers in Entre Ríos Province of Argentina, Uruguay and the south of Brazil, is s ...

Eurasian Steppe
The Eurasian Steppe, also simply called the Great Steppe or the steppes, is the vast steppe ecoregion of Eurasia in the temperate grasslands, savannas and shrublands biome. It stretches through Hungary, Bulgaria, Romania, Moldova and Transnistria, Ukraine, Western Russia, Siberia, Kazakhstan, Xinjiang, Mongolia and Manchuria, with one major exclave, the Pannonian steppe or Puszta, located mostly in Hungary. Since the Paleolithic age, the Steppe Route has connected Central Europe, Eastern Europe, Western Asia, Central Asia, East Asia and South Asia economically, politically and culturally through overland trade routes. The Steppe route is a predecessor not only of the Silk Road which developed during antiquity and the Middle Ages, but also of the Eurasian Land Bridge in the modern era. It has been home to nomadic empires and many large tribal confederations and ancient states throughout history, such as the Xiongnu, Scythia, Cimmeria, Sarmatia, Hunnic Empire, Chorasmia, Tr ...
