Niger Delta Swamp Forests
The Niger Delta swamp forests is a tropical moist forest ecoregion in southern Nigeria. It consists of freshwater swamp forests in the Niger Delta of the Niger River. This swamp forest is the second largest in Africa, after the Congolian swamp forests. Although there are large cities just outside the ecoregion, the area has been relatively isolated by the difficulty of building roads across the swamps, although this is changing with development of oil and logging industries. Scientific surveys have only begun in recent years, and new species were being identified into the 1990s. Location and description The Niger Delta swamp forests ecoregion covers a triangular territory at the mouth of the Niger River. The southern edge is set back about 10 km from the Gulf of Guinea, buffered by the Central African mangroves ecoregion where the effects of salt water are more pronounced. The western border of the ecoregion is formed along the Benin River, the northern tip is just north of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Niger Delta
The Niger Delta is the delta of the Niger River sitting directly on the Gulf of Guinea on the Atlantic Ocean in Nigeria. It is located within nine coastal southern Nigerian states, which include: all six states from the South South geopolitical zone, one state (Ondo) from South West geopolitical zone and two states (Abia and Imo) from South East geopolitical zone. The Niger Delta is a very densely populated region sometimes called the Oil Rivers because it was once a major producer of palm oil. The area was the British Oil Rivers Protectorate from 1885 until 1893, when it was expanded and became the Niger Coast Protectorate. The delta is a petroleum-rich region and has been the center of international concern over pollution that has resulted principally from major oil spills of multinational corporations of the petroleum industry. Geography The Niger Delta, as now defined officially by the Nigerian government, extends over about and makes up 7.5% of Nigeria's land mass. H ...

Tropical Monsoon Climate
An area of tropical monsoon climate (occasionally known as a sub-equatorial, tropical wet climate or a tropical monsoon and trade-wind littoral climate) is a tropical climate sub-type that corresponds to the Köppen climate classification category ''Am''. Tropical monsoon climates have monthly mean temperatures above in every month of the year and a dry season. The tropical monsoon climate is the intermediate climate between the wet Af (or tropical rainforest climate) and the drier Aw (or tropical savanna climate). A tropical monsoon climate's driest month has on average less than 60 mm, but more than 100-\left(\frac\right). This is in direct contrast to a tropical savanna climate, whose driest month has less than 60 mm of precipitation and also less than 100-\left(\frac\right) of average monthly precipitation. In essence, a tropical monsoon climate tends to either have more rainfall than a tropical savanna climate or have less pronounced dry seasons. A tropical monsoon c ...

Nigeria-Cameroon Chimpanzee
The Nigeria-Cameroon chimpanzee (''Pan troglodytes ellioti'') is a subspecies of the common chimpanzee which inhabits the rainforest along the border of Nigeria and Cameroon. Male Nigeria-Cameroon chimpanzees can weigh up to 70 kilos with a body length of up to 1.2 metres and a height of 1.3 metres. Females are significantly smaller. Like the nominate subspecies, the Nigeria-Cameroon chimpanzee has been classified as Endangered by the IUCN, indicating a high risk of extinction in the near future. History The Nigeria-Cameroon chimpanzee has been classified as the fourth subspecies of chimpanzee since 1997 and is the least studied of these subspecies. Its populations are falling across its limited natural range, with between 3500 and 9000 individuals remaining. Description Nigeria-Cameroon chimpanzees weigh around 80 kg for adult males in captivity and 65 kg for adult females in captivity. They stand 1–1.7 m tall when erect.

Ficus
''Ficus'' ( or ) is a genus of about 850 species of woody trees, shrubs, vines, epiphytes and hemiepiphytes in the family Moraceae. Collectively known as fig trees or figs, they are native throughout the tropics with a few species extending into the semi-warm temperate zone. The common fig (''F. carica'') is a temperate species native to southwest Asia and the Mediterranean region (from Afghanistan to Portugal), which has been widely cultivated from ancient times for its fruit, also referred to as figs. The fruit of most other species are also edible though they are usually of only local economic importance or eaten as bushfood. However, they are extremely important food resources for wildlife. Figs are also of considerable cultural importance throughout the tropics, both as objects of worship and for their many practical uses. Description ''Ficus'' is a pantropical genus of trees, shrubs, and vines occupying a wide variety of ecological niches; most are evergreen, bu ...

Klainedoxa Gabonensis
''Klainedoxa gabonensis'' is a large tropical African tree of the family Irvingiaceae growing to 40m in height. Its straight trunk is buttressed and up to 25m long, while its spreading evergreen crown makes it one of the largest trees of the rainforest. It is found from Senegal to Sudan, Cameroons, Ivory Coast, Democratic Republic of the Congo, Uganda and Tanzania, growing as far south as Angola and Zambia. The timber is dense (0.91-1.15) and extremely hard so that cutting and local usage is very limited, but trees are still exploited for firewood. Sapwood is thin, light brown in colour, and liable to insect attack. Heartwood is reddish to golden brown with wide dark veining, and zigzag markings. Poles are resistant to rotting and are used in hut construction and to make spring traps. This tree is usually left standing when forest is cleared for agriculture and forms a prominent part of the resultant landscape. Round about October the tree produces a spectacular flush of bright ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Elaeis Guineensis
''Elaeis guineensis'' is a species of palm commonly just called oil palm but also sometimes African oil palm or macaw-fat. It is the principal source of palm oil. It is native to west and southwest Africa, specifically the area between Angola and the Gambia; the species name, ''guineensis'', refers to the name for the area, Guinea, and not the modern country now bearing that name. The species is also now naturalised in Madagascar, Sri Lanka, Malaysia, Indonesia, Central America, Cambodia, the West Indies, and several islands in the Indian and Pacific Oceans. The closely related American oil palm ''Elaeis oleifera'' and a more distantly related palm, ''Attalea maripa'', are also used to produce palm oil. ''E. guineensis'' was domesticated in West Africa along the south-facing Atlantic coast. There is insufficient documentation and insufficient research to make any guesses as to when this occurred. Human use of oil palms may date as far back as 5,000 years in Egypt; in the late ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
