Douala Edéa National Park
Douala-Edéa National Park, formerly known as Douala-Edéa Wildlife Reserve, is a national park in the Littoral Region of Cameroon. Location The park is located on either side of the mouth of the Sanaga River along the shores of the Bight of Biafra opposite the island of Bioko. Lake Tissongo, a lagoon connected to the south bank of the Sanaga River by a tidal channel, is included in the reserve. Mouanko is the main town in the reserve, on the north shore of the Sanaga River. File:Lac tisongo, mouanko.png, Lake Tissongo File:River Sanaga.jpg, Sanara River History The reserve was established in 1932. Cameroon designated the reserve as a wildlife park for scientific purposes in 1971, and by 1974 the reserve had a conservator and guard post. It was designated a national park in 2018. As of 2000, it covered . Upgrade to full national park status was delayed since oil had been discovered in Cameroon's coastal areas, and the area could hold important reserves. In October 2018, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gymnosiphon Longistylus
''Gymnosiphon'' (yellowseed) is a genus of monocotyledonous flowering plants from the yam order. Like most of the other members of the family in which the plant is placed (Burmanniaceae), ''Gymnosiphon'' is entirely myco-heterotrophic genus that does not contain chlorophyll and respectively does not perform photosynthesis. ''Gymnosiphon'' is distributed across the moist, tropical regions of Asia, America and Africa. The plant has very small size and thin stems. Leaves are rudimentary and with appearance like scales or bracts. Its flowers are white in color, pale and solitary or sometimes collected in tiny inflorescences of few depending on the species. They are also actinomorphic with three larger outer tepals and three more inner and smaller ones. Phylogenetically ''Gymnosiphon'' is placed in the clade of Burmanniaceae Burmanniaceae is a Family (biology), family of flowering plants, consisting of 99 species of herbaceous plants in eight genera.

Coastal Erosion
Coastal erosion is the loss or displacement of land, or the long-term removal of sediment and rocks along the coastline due to the action of waves, currents, tides, wind-driven water, waterborne ice, or other impacts of storms. The landward retreat of the shoreline can be measured and described over a temporal scale of tides, seasons, and other short-term cyclic processes. Coastal erosion may be caused by hydraulic action, abrasion, impact and corrosion by wind and water, and other forces, natural or unnatural. On non-rocky coasts, coastal erosion results in rock formations in areas where the coastline contains rock layers or fracture zones with varying resistance to erosion. Softer areas become eroded much faster than harder ones, which typically result in landforms such as tunnels, bridges, columns, and pillars. Over time the coast generally evens out. The softer areas fill up with sediment eroded from hard areas, and rock formations are eroded away. Also erosion commonly ...

Red-eared Guenon
The red-eared guenon (''Cercopithecus erythrotis''), also called red-eared monkey, or russet-eared guenon is a primate species in the family Cercopithecidae. It is native to subtropical and tropical moist lowland forests in Cameroon, Equatorial Guinea and Nigeria. It is listed as Vulnerable on the IUCN Red List and is threatened by habitat loss, illegal bushmeat hunting and pet trade. Description The red-eared guenon is a small, colourful monkey with distinctive facial markings which involve blue fur around its eyes, a brick-red nose and ears, and yellow cheeks. The silky fur on the body consists of banded brown and pale hairs with grey limbs and a long, red tail. The long tails are partially prehensile and are used by infants to cling to the female. The red-eared guenon is an unobtrusive species which produces a quiet trill, unlike the loud long-distance calls made by other guenons. Males average 420 mm head and bodylength, with a 609 mm long tail, females are smaller ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red-capped Mangabey
The collared mangabey (''Cercocebus torquatus''), also called red-capped mangabey and white-collared mangabey is a species of primate in the family Cercopithecidae of Old World monkeys. It formerly included the sooty mangabey as a subspecies. As presently defined, the collared mangabey is monotypic. Description The collared mangabey has grey fur covering its body, but its common names refer to the colours on its head and neck. Its prominent chestnut-red cap gives it the name ''red-capped'', and its white collar gives it the names ''collared'' and ''white-collared''. Its ears are black and it has striking white eyelids, which is why some refer to it as the "four-eyed monkey". It has a dark grey tail that exceeds the length of the body and is often held with the white tip over its head. It has long Molar (tooth), molars and very large incisors. The average body mass for captive individuals ranges from for males and for females. Head-body length is in males and in females. ...

West African Manatee
The African manatee (''Trichechus senegalensis''), also known as the West African manatee, is a species of manatee that inhabits much of the western region of Africa – from Senegal to Angola. It is the only manatee species to be found in the Old World. Not a great deal is known about ''T. senegalensis.'' Taxonomy The African manatee was officially declared a species under the ''Trichechus senegalensis'' taxon in 1795 by naturalist Johann Heinrich Friedrich Link. No subspecies of this taxon are known. Although African manatees live in both coastal areas and isolated inland areas, genetic evidence suggests no significant differences between the two populations. The African manatee falls under the genus ''Trichechus'' with only two other species, the Amazonian manatee and the West Indian manatee, which are also sirenians. Range and habitat African manatees inhabit the widest ranges of habitats of any sirenian species, ranging from offshore islands in the Atlantic, rivers in the w ...

Blue Duiker
The blue duiker (''Philantomba monticola'') is a small antelope found in central, southern and eastern Africa. It is the smallest duiker. The species was first described by Swedish naturalist Carl Peter Thunberg in 1789. 12 subspecies are identified. The blue duiker reaches at the shoulder and weighs . Sexually dimorphic, the females are slightly larger than the males. The dark tail measures slightly above . It has short, spiky horns, around long and hidden in hair tufts. The subspecies show a great degree of variation in their colouration. The blue duiker bears a significant resemblance to Maxwell's duiker. Activity is diurnal (limited to daytime). Secretive and cautious, the blue duiker confines itself to the forest fringes. Territorial, individuals of opposite sexes form pairs and occupy territories, nearly large and marked by preorbital gland secretions. The blue duiker feeds on fallen fruits, foliage, flowers and pieces of bark, provided mainly by the forest canopies i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sitatunga
The sitatunga or marshbuck (''Tragelaphus spekii'') is a swamp-dwelling antelope found throughout central Africa, centering on the Democratic Republic of the Congo, the Republic of the Congo, Cameroon, parts of Southern Sudan, Equatorial Guinea, Burundi, Ghana, Botswana, Rwanda, Zambia, Gabon, the Central African Republic, Tanzania, Uganda and Kenya. The sitatunga is confined to swampy and marshy habitats. Here they occur in tall and dense vegetation as well as seasonal swamps, marshy clearings in forests, riparian thickets and mangrove swamps. Taxonomy and genetics The scientific name of the sitatunga is ''Tragelaphus spekii''. The species was first described by the English explorer John Hanning Speke in 1863. Speke first observed the sitatunga at a lake named "Little Windermere" (now Lake Lwelo, located in Kagera, Tanzania). In his book ''Journal of the Discovery of the Source of the Nile'', Speke called the animal "nzoé" (Kiswahili name for the animal) or "water-boc" (du ...

Black Colobus
The black colobus (''Colobus satanas''), or satanic black colobus, is a species of Old World monkey belonging to the genus ''Colobus''. The species is found in a small area of western central Africa. Black colobuses are large, completely covered with black fur, and like all other Colobus monkeys, do not have a thumb. The species has faced large declines in population due to habitat destruction and hunting by humans, and was consequently listed as Vulnerable on the IUCN Red List in 1994. Taxonomy The black colobus monkey is one of five recognised species in the genus ''Colobus''. The black colobus is the oldest species in this genera and is thought to have diverged 3-4 million years ago. There are two subspecies of black colobus monkey: *''Colobus satanas satanas'' – Bioko black colobus ( Waterhouse, 1838) *''Colobus satanas anthracinus'' – Gabon black colobus (Le Conte, 1857) Etymology The word '' 'Colobus' '' comes from the Greek word for 'mutilated', as all Colobus mon ...

Common Chimpanzee
The chimpanzee (''Pan troglodytes''), also known as simply the chimp, is a species of Hominidae, great ape native to the forest and savannah of tropical Africa. It has four confirmed subspecies and a fifth proposed subspecies. When its close relative the bonobo was more commonly known as the pygmy chimpanzee, this species was often called the common chimpanzee or the robust chimpanzee. The chimpanzee and the bonobo are the only species in the genus Pan (genus), ''Pan''. Evidence from fossils and DNA sequencing shows that ''Pan'' is a sister taxon to the Human evolution, human lineage and is humans' closest living relative. The chimpanzee is covered in coarse black hair, but has a bare face, fingers, toes, palms of the hands, and soles of the feet. It is larger and more Robustness (morphology), robust than the bonobo, weighing for males and for females and standing . The chimpanzee lives in groups that range in size from 15 to 150 members, although individuals travel and forag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest Elephant
The African forest elephant (''Loxodonta cyclotis'') is one of the two living African elephant species. It is native to humid forests in West Africa and the Congo Basin. It is the smallest of the three living elephant species, reaching a shoulder height of . Both sexes have straight, down-pointing tusks, which erupt when they are 1–3 years old. It lives in family groups of up to 20 individuals. Since it forages on leaves, seeds, fruit, and tree bark, it has been referred to as the 'megagardener of the forest'. It contributes significantly to maintain the composition and structure of the Guinean Forests of West Africa and the Congolese rainforests. The first scientific description of the species was published in 1900. During the 20th century, overhunting caused a sharp decline in population, and by 2013 it was estimated that less than 30,000 individuals remained. It is threatened by habitat loss, fragmentation, and poaching. The conservation status of populations varies across r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wouri Estuary
The Wouri estuary, or Cameroon estuary is a large tidal estuary in Cameroon where several rivers come together, emptying into the Bight of Biafra. Douala, the largest city in Cameroon, is at the mouth of the Wouri River where it enters the estuary. The estuary contains extensive mangrove forests, which are being damaged by pollution and population pressures. Hydrology The estuary lies to the east of Mount Cameroon and empties into the Bight of Biafra. It is fed by the Mungo, Wouri and Dibamba rivers. The estuary lies in the Douala Basin, a low-lying depression about on average about sea level, with many creeks, sand bars and lagoons. The Plio-Pleistocene Wouri alluvial aquifer, a multi-layer system with alternating sequences of marine sands and estuarine mud and silt lies below the estuary and surrounding region and is an important source of well water. The upper aquifer in this system is an unconfined sandy horizon that is hydraulically connected to the brackish waters of ...
