Pennant's Colobus
Pennant's colobus or Pennant's red colobus (''Piliocolobus pennantii'') is a species of tree-dwelling primate in the family Cercopithecidae. It is endemic to tropical Central Africa. Three subspecies have traditionally been recognised but its distribution is peculiarly disjunct and has been considered a biogeographical puzzle, with one population on the island of Bioko (Equatorial Guinea), a second in the Niger River Delta in southern Nigeria, and a third in east-central Republic of Congo. It is found in rainforests and marshy forests. It is threatened by habitat loss and hunting for bushmeat. Taxonomy and etymology Pennant's colobus was first described in 1838 by George Robert Waterhouse, curator at the Zoological Society of London's museum, and was named in honour of the naturalist and traveller Thomas Pennant. Three subspecies of this red colobus are traditionally recognized: The Bioko red colobus (''Procolobus pennantii pennantii''), the Niger Delta red colobus (''Procolobus ...

George Robert Waterhouse
George Robert Waterhouse (6 March 1810 – 21 January 1888) was an English natural history, naturalist. He was a keeper at the department of geology and later curator of the Zoological Society of London's museum. Early life George was born in Somers Town to James Edward Waterhouse and Mary Newman. His father was a solicitor's clerk and an amateur entomologist. He was the brother of Frederick George Waterhouse, who also became a zoologist. George went to school at Koekelberg, near Brussels. He returned to England in 1824 and worked as an apprentice to an architect. Part of the work was in designing the garden of Charles Knight in the Vale of Health, Hampstead and the ornamentation for St. Dunstan's Church. Natural history George became interested in entomology through his father and he founded the Entomological Society of London along with Frederick William Hope in 1833 with himself as honorary curator. He became its president in 1849–50. He wrote articles for Knight's ''P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bouvier's Red Colobus
Bouvier's red colobus (''Piliocolobus bouvieri'') is a species of colobus monkey rediscovered in the Republic of the Congo in 2015, after four decades without a confirmed sighting. Description Bouvier's red colobus has brownish-red fur on its body that is lighter than its closest relative, the Pennant's colobus (''P. pennantii''). Its head has a patch of black to chocolate brown fur that is smaller than that of ''P. pennantii''. It has a white chin and whiskers. A black band of fur extends from above the eyes to the temples. The monkey's eyes are surround by large, pink eyerings. The tail of ''P. bouvieri'' is long in proportion to its small body and is dark brown at the root, fading to brownish-red at the tip. The fur on the species' underside is lighter than the fur on its back. Bouvier's red colobus is thought to exhibit considerable facial variation from individual to individual, varying from light flesh-colored with blackish cheeks and brows to darker tones throughou ...

Tannin
Tannins (or tannoids) are a class of astringent, polyphenolic biomolecules that bind to and precipitate proteins and various other organic compounds including amino acids and alkaloids. The term ''tannin'' (from Anglo-Norman ''tanner'', from Medieval Latin ''tannāre'', from ''tannum'', oak bark) refers to the use of oak and other bark in tanning animal hides into leather. By extension, the term ''tannin'' is widely applied to any large polyphenolic compound containing sufficient hydroxyls and other suitable groups (such as carboxyls) to form strong complexes with various macromolecules. The tannin compounds are widely distributed in many species of plants, where they play a role in protection from predation (acting as pesticides) and might help in regulating plant growth. The astringency from the tannins is what causes the dry and puckery feeling in the mouth following the consumption of unripened fruit, red wine or tea. Likewise, the destruction or modification of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gestation
Gestation is the period of development during the carrying of an embryo, and later fetus, inside viviparous animals (the embryo develops within the parent). It is typical for mammals, but also occurs for some non-mammals. Mammals during pregnancy can have one or more gestations at the same time, for example in a multiple birth. The time interval of a gestation is called the '' gestation period''. In obstetrics, ''gestational age'' refers to the time since the onset of the last menses, which on average is fertilization age plus two weeks. Mammals In mammals, pregnancy begins when a zygote (fertilized ovum) implants in the female's uterus and ends once the fetus leaves the uterus during labor or an abortion (whether induced or spontaneous). Humans In humans, pregnancy can be defined clinically or biochemically. Clinically, pregnancy starts from first day of the mother's last period. Biochemically, pregnancy starts when a woman's human chorionic gonadotropin (hCG) levels ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Territory (animal)
In ethology, territory is the sociographical area that an animal consistently defends against conspecific competition (or, occasionally, against animals of other species) using agonistic behaviors or (less commonly) real physical aggression. Animals that actively defend territories in this way are referred to as being territorial or displaying territorialism. Territoriality is only shown by a minority of species. More commonly, an individual or a group of animals occupies an area that it habitually uses but does not necessarily defend; this is called its home range. The home ranges of different groups of animals often overlap, and in these overlap areas the groups tend to avoid each other rather than seeking to confront and expel each other. Within the home range there may be a ''core area'' that no other individual group uses, but, again, this is as a result of avoidance. Function The ultimate function of animals inhabiting and defending a territory is to increase the indi ... [...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 ...

Likouala-aux-Herbes
The Likouala-aux-Herbes is a river in the Republic of the Congo. It is a tributary of the Sangha River, which in turn is a tributary of the Congo River. It gives its name to the Likouala Department. Location The Likouala-aux-Herbes is almost long and is the main tributary of the Sangha River. The lower Sangha, the Likouala-aux-Herbes and Likouala-Mossaka rivers flow through the Congolese Cuvette, a huge depression. The soil of this region is sand or clay Quaternary fluvial alluvia. The Likouala aux Herbes basin is located on the predominantly sandy Quaternary formations of the Congolese basin. The course of the Likouala meanders and shifts over time. The coefficient of sinuosity is more than 1.5 in the upper section, around 2.0 in the middle section and in the lower section as high as 2.8. The lower sections of the Sangha and Likouala-aux-Herbes flow through flat land with little difference in elevation between the two rivers. Part of the lower section of the Sangha River divide ...

Prehensile Tail
A prehensile tail is the tail of an animal that has adapted to grasp or hold objects. Fully prehensile tails can be used to hold and manipulate objects, and in particular to aid arboreal creatures in finding and eating food in the trees. If the tail cannot be used for this it is considered only partially prehensile - such tails are often used to anchor an animal's body to dangle from a branch, or as an aid for climbing. The term ''prehensile'' means "able to grasp" (from the Latin ''prehendere'', to take hold of, to grasp). Evolution One point of interest is the distribution of animals with prehensile tails. The prehensile tail is predominantly a New World adaptation, especially among mammals. Many more animals in South America have prehensile tails than in Africa and Southeast Asia. It has been argued that animals with prehensile tails are more common in South America because the forest there is denser than in Africa or Southeast Asia. In contrast, less dense forests such as in S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
