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] |
North Saharan Steppe And Woodlands
The North Saharan steppe and woodlands is a desert ecoregion, in the deserts and xeric shrublands biome, that forms the northern edge of the Sahara. It extends east and west across Northern Africa, south of the Mediterranean dry woodlands and steppe ecoregion of the Maghreb and Cyrenaica, which is part of the Mediterranean forests, woodlands, and scrub biome. Winter rains sustain shrublands and dry woodlands that form an ecotone between the Mediterranean climate regions to the north and the hyper-arid Sahara Desert ecoregion to the south. Geography The North Saharan steppe and woodlands covers in Algeria, Egypt, Libya, Mauritania, Morocco, Tunisia, and Western Sahara. Climate The climate in this ecoregion is hot and dry in the summer but cooler with some rain in the winter. Atlantic depressions sometimes penetrate inland between October and April. Rainfall is erratic, but averages in the north and in the south. During the summer, temperatures regularly rise to and evapo ...

Western Mediterranean
The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Western and Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The Sea has played a central role in the history of Western civilization. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide.

Permanent Maghreb
The Permanent Maghreb of World Wide Fund for Nature is a freshwater ecoregion of North Africa. Geography The Permanent Maghreb ecoregion covers an area of 950,180 square kilometers, and extends across the portions of Algeria, Mauritania, Morocco, Tunisia, and Western Sahara. It occupies the Mediterranean climate region of northern Africa, and is characterized by rivers and streams which flow on the surface year-round. The ecoregion is bounded on the north by the Atlantic Ocean and Mediterranean Sea, and to the south by the Temporary Maghreb freshwater ecoregion, which covers the northern portion of the Sahara and is characterized by temporary or seasonally-flowing rivers and streams. The WWF divides the ecoregion into two. Atlantic Northwest Africa lies in northwestern Africa, covering most of Morocco and Western Sahara and portions of Mauritania and Algeria. The ecoregion covers the western Atlas Mountains complex, including the Anti-Atlas to the west, the High Atlas, the Mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saharan Halophytics
The Saharan halophytics ecoregion (WWF ID: PA0905) covers a series of low-lying evaporite depressions and wetlands spread across North Africa. The depressions are characteristically saline, variously chotts (saline lakes fed by groundwater and some winter rains) or sabkhas (coastal, supratidal mudflats of evaporites). The plants of the areas are highly specialized to survive in the harsh environment, with many being xerophytes (drought-tolerant) and halophytes (salt-tolerant). The biodiversity of the areas has been relatively protected by their isolation, and unsuitability of alkaline soil for farming. Location and description The sites making up this ecoregion contain a wide variety of habitat types: salt pans, seasonal salt lakes, salt marshes, reed beds, and spring-fed oases. Chott and sebkha areas exist in arid regions with clay soils heavy with evaporites. Specific locations assigned to this ecoregion include: * Chott Melrhir (Northeast Algeria). An extension of t ...

Flooded Grasslands And Savannas
Flooded grasslands and savannas is a terrestrial biome of the WWF biogeographical system, consisting of large expanses or complexes of flooded grasslands. These areas support numerous plants and animals adapted to the unique hydrologic regimes and soil conditions. Large congregations of migratory and resident waterbirds may be found in these regions. However, the relative importance of these habitat types for these birds as well as more vagile taxa typically varies as the availability of water and productivity annually and seasonally shifts among complexes of smaller and larger wetlands throughout a region. This habitat type is found on four of the continents on Earth. Some globally outstanding flooded savannas and grasslands occur in the Everglades, Pantanal, Lake Chad flooded savanna, Zambezian flooded grasslands, and the Sudd. The Everglades, with an area of , are the world's largest rain-fed flooded grassland on a limestone substrate, and feature some 11,000 species of ...

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.

Mediterranean Woodlands And Forests
The Mediterranean woodlands and forests is an ecoregion in the coastal plains, hills, and mountains bordering the Mediterranean Sea and Atlantic Ocean in North Africa. It has a Mediterranean climate, and is in the Mediterranean forests, woodlands, and scrub biome. Geography The Mediterranean woodlands and forests occupy an area of in Morocco, Algeria, Tunisia, the Spain, Spanish plazas de soberanía, and Libya. The main portion of the ecoregion extends along the coastal plains and hills of the Maghreb, from near Agadir on the Atlantic coast of Morocco in the west to Sfax on the Gulf of Gabes in Tunisia. The ecoregion extends inland to cover the lower slopes of the Middle Atlas and High Atlas ranges of Morocco, with isolated enclaves along the Saharan Atlas range of Algeria. Two coastal enclaves lie further east along the Mediterranean Sea: one along the southeastern Tunisian shore of the Gulf of Gabes, including the island of Djerba; and the second in the Jebel Akhdar, Libya, J ...
