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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nile Delta Flooded Savanna
The Nile Delta flooded savanna, ecoregion (WWF ID: PA0904) covers both the Nile Delta proper, where the Nile River enters the Mediterranean Sea, as well as the river floodplains of the Nile up-river to the Aswan Dam. Since the Aswan Dam was completed in the 1970s, the Nile on this stretch has not been subject to annual flooding, leading the loss of much of the papyrus sedge ('' Cyperus papyrus'') swamps and other marshes along the river. Location and description At the northern end is the Nile Delta, 175 km long by 260 km wide. There are some lakes and lagoons with marshes near the seacoast; some of the larger are Lake Burullus and Lake Manzala. The topsoil in the delta is up to 21 meters in depth and intensely used for agriculture. The soil quality has been degrading, however, due to the loss of additional sediments from floods, and the use of fertilizers has increased. The western coast of the delta is divided from the sea by a portion of the Mediterranean ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Levantine Sea
The Levantine Sea (Arabic: بحر الشام, tr, Levanten Denizi, el, Θάλασσα του Λεβάντε) is the easternmost part of the Mediterranean Sea. Geography The Levantine Sea is bordered by Turkey in the north and north-east corner, Syria, Lebanon, Israel, and Palestine in the east, Egypt in the south, and the Aegean Sea in the northwest. Where it is used as a term its western border is amorphous, hence Mediterranean is more commonly used. The open western border to the next part of the Mediterranean (the Libyan Sea) is defined as a line from headland Ras al-Helal in Libya to Gavdos, south of the western half of Crete. The largest island in its subset of water is Cyprus. The greatest depth of is found in the Pliny Trench, about south of Crete. The Levantine Sea covers . The northern part of the Levantine Sea between Cyprus and Turkey can be further specified as the Cilician Sea, a term more arcane. Also in the north are two large bays, the Gulf of İskend ...

Red Sea Coastal
Red is the color at the long wavelength end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of approximately 625–740 nanometres. It is a primary color in the RGB color model and a secondary color (made from magenta and yellow) in the CMYK color model, and is the complementary color of cyan. Reds range from the brilliant yellow-tinged scarlet and vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy. Red pigment made from ochre was one of the first colors used in prehistoric art. The Ancient Egyptians and Mayans colored their faces red in ceremonies; Roman generals had their bodies colored red to celebrate victories. It was also an important color in China, where it was used to color early pottery and later the gates and walls of palaces. In the Renaissance, the brilliant red costumes for the nobility and wealthy were dyed with kermes and cochineal. The 19th century brou ...

Nile Delta
The Nile Delta ( ar, دلتا النيل, or simply , is the delta formed in Lower Egypt where the Nile River spreads out and drains into the Mediterranean Sea. It is one of the world's largest river deltas—from Alexandria in the west to Port Said in the east, it covers of Mediterranean coastline and is a rich agricultural region. From north to south the delta is approximately in length. The Delta begins slightly down-river from Cairo. Geography From north to south, the delta is approximately in length. From west to east, it covers some of coastline. The delta is sometimes divided into sections, with the Nile dividing into two main distributaries, the Damietta and the Rosetta, flowing into the Mediterranean at port cities with the same name. In the past, the delta had several distributaries, but these have been lost due to flood control, silting and changing relief. One such defunct distributary is Wadi Tumilat. The Suez Canal is east of the delta and enters ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lower Nile
Lower Egypt ( ar, مصر السفلى '; ) is the northernmost region of Egypt, which consists of the fertile Nile Delta between Upper Egypt and the Mediterranean Sea, from El Aiyat, south of modern-day Cairo, and Dahshur. Historically, the Nile River split into seven branches of the delta in Lower Egypt. Lower Egypt was divided into nomes and began to advance as a civilization after 3600 BC. Today, it contains two major channels that flow through the delta of the Nile River – Mahmoudiyah Canal (ancient Agathos Daimon) and Muways Canal (, "waterway of Moses"). Name In Ancient Egyptian, Lower Egypt was as ''mḥw'' and means ''"north"''. Later on, during Antiquity and the Middle Ages, Greeks and Romans called it ''Κάτω Αἴγυπτος'' or ''Aegyptus Inferior'' both meaning "Lower Egypt", but Copts carried on using the old name related to the north – ''Tsakhet'' () or ''Psanemhit'' () meaning the "Northern part". It was further divided into number of regi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dry Sahel
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 h ...

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 ...
