Ecoregion
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. Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Somali Acacia–Commiphora Bushlands And Thickets
The Somali ''Acacia''–''Commiphora'' bushlands and thickets is a semi-arid tropical grasslands, savannas, and shrublands ecoregion in the Horn of Africa. It is home to diverse communities of plants and animals, including several endemic species. Setting The Somali ''Acacia''–''Commiphora'' bushlands and thickets ecoregion occupies most of the Horn of Africa east and south of the Ethiopian Highlands, including eastern Ethiopia's Haud plateau and adjacent parts of Somaliland, Somalia and northeastern Kenya. It also extends along the floor of the East African Rift, bisecting the Ethiopian highlands, and along the northeastern edge of the highlands into Eritrea and Sudan. The ecoregion is bounded on the southwest by the Northern Acacia–Commiphora bushlands and thickets and the Masai xeric grasslands and shrublands. To the south, it is bounded by the humid Northern Zanzibar–Inhambane coastal forest mosaic in the lower Shebelle–Jubba River valley. The Hobyo grasslands and ...

Ethiopian Xeric Grasslands And Shrublands
The Ethiopian xeric grasslands and shrublands ecoregion is a semi-desert strip on or near the Red Sea and the Gulf of Aden coasts in Eritrea, Ethiopia, Djibouti and Somaliland. This ecoregion lies mainly between sea level and 800 meters (m) elevation. There are, however, many hills and massifs, which range up to 1300 m as well as outstanding fault-induced depressions, such as the Danakil, lying as low as 155 m below sea level. This region is extremely active tectonically, experiencing many earthquakes and intermittently active volcanoes. Rainfall is very low and yearly averages range from 100 to 200 millimeters (mm), with less rain falling closer to the coast. There are many species of interest, including the endemic Archer's lark (''Heteromirafra archeri''), a species of dragon tree ('' Dracaena ombet''), and a large suite of desert ungulates, including the last viable population of African wild ass (''Equus africanus somalicus'').

Eritrean Coastal Desert
The Eritrean coastal desert ecoregion is a harsh sand and gravel strip along the southern part of the coast of Eritrea and the Red Sea coast of Djibouti. This coast is of ecological importance as a channel for the mass migration of birds of prey. Location and description The ecoregion consists of a coastal strip in Eritrea's Southern Red Sea Region, which stretches along the Red Sea coast to Obock in Djibouti. Flora The flora of the coastal strip consists of herbs and grasses suited to the dry climate such as ''Aerva javanica'', ''Cymbopogon schoenanthus'', ''Panicum turgidum'', and ''Lasiurus scindicus'', along with some Umbrella thorn ''Acacia tortilis'' and '' Acacia asak'' trees and '' Rhigozum somalense'' and '' Caesalpinia erianthera'' shrubs. Fauna This is one of the busiest raptor migration routes in the world as birds such as buzzards and eagles make their way to Africa for the winter along the Red Sea coast and across the Bab-el-Mandeb strait. Animals found here inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deserts And Xeric Shrublands
Deserts and xeric shrublands are a biome defined by the World Wide Fund for Nature. Deserts and xeric (ancient Greek xērós, “dry") shrublands form the largest terrestrial biome, covering 19% of Earth's land surface area. Ecoregions in this habitat type vary greatly in the amount of annual rainfall they receive, usually less than annually except in the margins. Generally evaporation exceeds rainfall in these ecoregions. Temperature variability is also diverse in these lands. Many deserts, such as the Sahara, are hot year-round, but others, such as East Asia's Gobi, become quite cold in winter. Temperature extremes are a characteristic of most deserts. High daytime temperatures give way to cold nights because there is no insulation provided by humidity and cloud cover. The diversity of climatic conditions, though quite harsh, supports a rich array of habitats. Many of these habitats are ephemeral in nature, reflecting the paucity and seasonality of available water.

Ethiopian Montane Grasslands And Woodlands
The Ethiopian montane grasslands and woodlands is a montane grasslands and shrublands ecoregion in Ethiopia. It occupies the middle elevations of the Ethiopian Highlands, between the high-altitude Ethiopian montane moorlands and the lower-elevation Ethiopian montane forests. The ecoregion includes montane grasslands, open woodlands, shrublands, and forest. Geography The ecoregion includes the middle elevations of the Ethiopian Highlands, between 1,800 to 3,000 meters elevation. The northern and southern portions of the highlands are separated by the African Rift Valley. Flora The natural vegetation includes grassland, open woodlands, shrubland including thorn scrub, and areas of forest, particularly in the more humid southern highlands. Dominant woodland trees include the conifers African juniper (''Juniperus procera'') and ''Afrocarpus falcatus'', and the broadleaved ''Hagenia abyssinica''. Parts of the highlands have been densely populated for centuries, and the vegetation has ... [...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 And ...

Sahelian Acacia Savanna
The Sahel (; ar, ساحل ' , "coast, shore") is a region in North Africa. It is defined as the ecoclimatic and biogeographic realm of transition between the Sahara to the north and the Sudanian savanna to the south. Having a hot semi-arid climate, it stretches across the south-central latitudes of Northern Africa between the Atlantic Ocean and the Red Sea. The Sahel part of Africa includes – from west to east – parts of northern Senegal, southern Mauritania, central Mali, northern Burkina Faso, the extreme south of Algeria, Niger, the extreme north of Nigeria, Cameroon and Central African Republic, central Chad, central and southern Sudan, the extreme north of South Sudan, Eritrea and Ethiopia. Historically, the western part of the Sahel was sometimes known as the Sudan region (''bilād as-sūdān'' "lands of the Sudan"). This belt was located between the Sahara and the coastal areas of West Africa. There are frequent shortages of food and water due to the dry harsh cl ...

Tropical And Subtropical Grasslands, Savannas, And Shrublands
Tropical and subtropical grasslands, savannas, and shrublands is a terrestrial biome defined by the World Wide Fund for Nature. The biome is dominated by grass and/or shrubs located in semi-arid to semi- humid climate regions of subtropical and tropical latitudes. Description Grassland is dominated by grass and other herbaceous plants. Savanna is grassland with scattered trees. Shrubland is dominated by woody or herbaceous shrubs. Large expanses of land in the tropics do not receive enough rainfall to support extensive tree cover. The tropical and subtropical grasslands, savannas, and shrublands are characterized by rainfall levels between per year. Rainfall can be highly seasonal, with the entire year's rainfall sometimes occurring within a couple of weeks. African savannas occur between forest or woodland regions and grassland regions. Flora includes acacia and baobab trees, grass, and low shrubs. Acacia trees lose their leaves in the dry season to conserve moisture, while ...
