Mediterranean Northwest Africa
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 Middle ...

Sebou River
Sebou (Berber language, Berber: Asif en Sbu, ar, سبو) is a river in northern Morocco. At its source in the Middle Atlas mountains it is known as the Guigou River (Berber: Asif n Gigu). The river is 496 kilometers long and has an average water flow of 137 m3/s, which makes it the largest North African river by volume. It passes near the city of Fes, Morocco, Fes and discharges to the Atlantic Ocean at Mehdya, Morocco, Mehdya. Sebou is navigable for only 16 km as far as the city of Kenitra, which has the only river port in Morocco. Its most important tributaries are the Ouergha River, Baht River and Inaouen River. The river supports irrigation in Morocco's most fertile region: the Gharb-Chrarda-Béni Hssen, Gharb. History Sebou was known in antiquity as Sububus. Pliny the Elder states that it was "magnificus et navigabilis" (grand and navigable), flowing near the towns of Iulia Valentia Banasa, Banasa (near the city of Mechra Bel Ksiri) and Thamusida. There is scant hist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cobitidae
Cobitidae, also known as the True loaches, is a family of Old World freshwater fish. They occur throughout Eurasia and in Morocco, and inhabit riverine ecosystems. Today, most "loaches" are placed in other families (see below). The family includes about 260 described species. New species are being described regularly.Perdices, A., Bohlen, J., Šlechtová, V. & Doadrio, I. (2016): Molecular Evidence for Multiple Origins of the European Spined Loaches (Teleostei, Cobitidae). ''PLoS ONE, 11 (1): e0144628.'' Description and ecology The body forms of the Cobitidae tend to be vermiform – worm-shaped, long and thin. Most true loaches do not have true scales, and like many other Cypriniformes or catfishes, they have barbels at their mouths (usually three to six pairs). Some other traits typically found in this family are a small bottom-facing mouth suited to their scavenging benthic lifestyle, an erectile spine below the eye, and a single row of pharyngeal (throat) teeth.

Cobitis Maroccana
''Cobitis maroccana'' is a species of ray-finned fish in the family Cobitidae. Taxonomy The taxonomy of the Cobitis marrocana is as follows: *Kingdom-Animalia *Phylum-Chordata *Class-Actinopterygii *Order-Cypriniformes *Family-Cobitidae Biology The Cobitis marrocana is now recorded to be least concern. It now has a competitor species called the Lepomis spp. The competition has created a decline in the population of the Cobitis marrocana. Another negative influence that could affect the population as well is the effect of pollution on the habitat of the Cobitis marrocana. Size The average size of an unsexed male is about 8 centimeters. Location It is found only in Morocco and Spain. It is known to be common to the rivers of Loukkos and Sebou, and it is also found in the Atlantic coast of northern Morocco. The climate that it is found in is temperate. It is common to highland and lowland freshwater. Habitat Its natural habitats are river A river is a natural flow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salmonidae
Salmonidae is a family of ray-finned fish that constitutes the only currently extant family in the order Salmoniformes . It includes salmon (both Atlantic and Pacific species), trout (both ocean-going and landlocked), chars, freshwater whitefishes, graylings, taimens and lenoks, which are collectively known as the salmonids ("salmon-like fish"). The Atlantic salmon (''Salmo salar''), whose Latin name became that of its genus ''Salmo'', is also the source of the family and order names. Salmonids have a relatively primitive appearance among the teleost fish, with the pelvic fins being placed far back, and an adipose fin towards the rear of the back. They have slender bodies, with rounded scales and forked tails, and their mouths contain a single row of sharp teeth. Although the smallest species is just long as an adult, most are much larger, with the largest reaching . All salmonids spawn in fresh water of upper reaches of rivers and creeks, but in many cases, the fish spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chott
In geology, a chott, shott, or shatt (; ar, شط, šaṭṭ, lit=bank, coast) is a salt lake in Africa's Maghreb that stays dry for much of the year but receives some water in the winter. The elevation of a chott surface is controlled by the position of the water table and capillary fringe, with sediment deflation occurring when the water table falls and sediment accumulation occurring when the water table rises.Swezey, C.S., 2003, The role of climate in the creation and destruction of continental stratigraphic records: An example from the northern margin of the Sahara Desert, in Cecil, C.B., and Edgar, N.T., eds., Climate Controls on Stratigraphy: SEPM (Society for Sedimentary Geology) Special Publication 77, p. 207-225. They are formed—within variable shores—by the spring thaw from the Atlas mountain range, along with occasional rainwater or groundwater sources in the Sahara, such as the Bas Saharan Basin. Water sources The chotts of the Sahara are fed intermittently d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Moulouya River
The Moulouya River ( Berber: ''iɣẓer en Melwect'', ) is a 520 km-long river in Morocco. Its sources are located in the Ayashi mountain in the Middle Atlas. It empties into the Mediterranean Sea near Saïdia, in northeast Morocco. Water level in the river often fluctuates. The river is used for irrigation and is dammed by the Hassan II and Mohamed V Dams. History Before French colonisation, the Moulouya River was considered as the border between Ottoman Algeria and the dynasties that controlled Morocco. A battle between the Algerians and the Alawites took place in 1692 at the ford of this river. The Romans called this river ''Malva''. In medieval British pseudo-history, it was mentioned as a location along the route supposedly travelled by the ancestors of the Scotti, and by Brutus of Troy. The Moulouya River formed the eastern border of the kingdom of Mauretania since King Bocchus I, and more recently of the Rif Republic in the 1920s, a small part of Morocco containing ...

Tell Atlas
The Tell Atlas ( ar, الاطلس التلي, Latn, ar, al-ʾaṭlas al-tlī) is a mountain chain over in length, belonging to the Atlas mountain ranges in North Africa, stretching mainly across northern Algeria, with ends in both north-eastern Morocco and north-western Tunisia. The ranges of this system have an average elevations of about and form a natural barrier between the Mediterranean and the Sahara. Its highest summit is the high Lalla Khedidja in the Jurjura Range. Several large cities such as the Algerian capital, Algiers, with ~1,500,000 residents (2005) and Oran with ~770,000 residents (2005) lie at the base of the Tell Atlas. The Algerian city Constantine with approximately 505,000 residents (2005) lies 80 km inland and directly in the mountains at 650 meters in elevation. A number of smaller towns and villages are situated within the Tell; for example, Chiffa is nestled within the Chiffa gorge. Geography The Tell Atlas runs parallel to the Mediterranean c ...
