Western Red Colobus
The western red colobus (''Piliocolobus badius''), also known as the bay red colobus, rust red colobus or Upper Guinea red colobus, is a species of Old World monkey in West African forests from Senegal to Ghana. All other species of red colobuses have formerly been considered subspecies of ''P. badius''. The monkey is a frequent prey of the common chimpanzee. In 1994, western red colobus monkeys infected many chimpanzees with Ebola virus after being hunted and consumed by the chimps. Subspecies According to Groves (2005) the Western red colobus has three subspecies, including the nominate: * Bay red colobus, ''Piliocolobus badius badius'' * Temminck's red colobus, ''Piliocolobus badius temminckii'' * Miss Waldron's red colobus, ''Piliocolobus badius waldronae'' ''P. b. waldronae'' is critically endangered, possibly even extinct. The other two subspecies are endangered. Under more recent taxonomies, these are generally considered separate species. Groves concurs with this rev ...

Robert Kerr (writer)
Robert Kerr (20 October 1757 – 11 October 1813) was a Scottish surgeon, writer on scientific and other subjects, and translator. Life Kerr was born in 1757 in Bughtridge, Roxburghshire, the son of James Kerr, a jeweller, who served as MP for Edinburgh 1747–1754, and his wife Elizabeth. He was sent to the High School in Edinburgh. He studied medicine at the University of Edinburgh and practised at the Edinburgh Foundling Hospital as a surgeon. He was elected a Fellow of the Royal Society of Edinburgh in 1788. His proposers were Alexander Fraser Tytler, James Russell and Andrew Dalzell. At this time, he lived at Foresters Wynd off the Royal Mile in Edinburgh. He translated several scientific works into English, such as Antoine Lavoisier's work of 1789, '' Traité Élémentaire de Chimie'', published under the title ''Elements of Chemistry in a New Systematic Order containing All the Modern Discoveries'', in 1790. In 1792, he published ''The Animal Kingdom'', the first tw ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Miss Waldron's Red Colobus
Miss Waldron's red colobus (''Piliocolobus waldronae'') is a species of the red colobus native to West Africa. It had previously been described as a subspecies of the western red colobus, ''P. badius''. It has not been officially sighted since 1978 and was considered extinct in 2000. However, new evidence suggests that a very small number of these monkeys may be living in the southeast corner of Côte d'Ivoire. The IUCN Red List notes Miss Waldron's red colobus as critically endangered. Miss Waldron's red colobus was discovered in December 1933 by Willoughby P. Lowe, a British Museum (Natural History) collector who had shot eight specimens of the animal. Robert William Hayman named it after a fellow museum employee, Miss Fanny Waldron, who assisted in the expedition where Lowe collected the eight specimens. Description Black fur covers the majority of Miss Waldron's red colobus, but a distinctive pattern of bright red fur can be found on its forehead and thighs, allowing it t ...

Mammals Described In 1792
A mammal () is a vertebrate animal of the class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors diverged in the Carboniferous Period over 300 million years ago. Around 6,640 extant species of mammals have been described and divided into 27 orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including cats, dogs, and seals). Mammals are the only living members of Synapsida; this clade, together with Sauropsida (reptiles and birds), constitu ...

Endangered Fauna Of Africa
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct.

Piliocolobus
Red colobuses are Old World monkeys of the genus ''Piliocolobus''. It was formerly considered a subgenus within the genus '' Procolobus'', which is now restricted to the olive colobus. They are closely related to the black-and-white colobus monkeys (genus ''Colobus''), and some species are often found in groups with the blue monkey. The western red colobus is frequently hunted by the common chimpanzee. The members of this genus are found in western, central and eastern Africa, and the species have largely allo- or parapatric distributions. They are primarily arboreal and most are restricted to humid forests, but the Zanzibar red colobus prefers coastal thickets and scrub. Red colobuses are highly sensitive to hunting and habitat destruction, and have been referred to as probably the most threatened taxonomic group of primates in Africa. If following the taxonomic treatment advocated in ''Mammal Species of the World'', all species except the Udzungwa, Semliki, Oustalet's an ...

Bandama River
The Bandama River is the longest river in Ivory Coast with a length of some 800 kilometers. The south-flowing river is fed by the Marahoué, Solomougou, Kan and Nzi rivers and empties into the Tagba Lagoon and the Gulf of Guinea. The Bandama flows through Lake Kossou, a large artificial lake created in 1973 by the construction of the Kossou Dam at Kossou. Yamoussoukro, the capital of Ivory Coast Ivory Coast, also known as Côte d'Ivoire and officially the Republic of Côte d'Ivoire, is a country on the southern coast of West Africa. Its capital city of Yamoussoukro is located in the centre of the country, while its largest List of ci ..., is located adjacent to the Bandama River.

Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Colobus
Black-and-white colobuses (or colobi) are Old World monkeys of the genus ''Colobus'', native to Africa. They are closely related to the red colobus monkeys of genus '' Piliocolobus''. There are five species of this monkey, and at least eight subspecies. They are generally found in high-density forests where they forage on leaves, flowers and fruit. Social groups of colobus are diverse, varying from group to group. Resident-egalitarian and allomothering relationships have been observed among the female population. Complex behaviours have also been observed in this species, including greeting rituals and varying group sleeping patterns. Colobi play a significant role in seed dispersal. Etymology The word "colobus" comes from the Greek (''kolobós'', "docked", "maimed") and refers to the stump-like thumb. Taxonomy Fossil species *†'' Colobus flandrini'' *†'' Colobus freedmani'' Behaviour and ecology Colobus habitats include primary and secondary forests, riverine for ...

Critically Endangered
An IUCN Red List critically endangered (CR or sometimes CE) species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. As of December 2023, of the 157,190 species currently on the IUCN Red List, 9,760 of those are listed as critically endangered, with 1,302 being possibly extinct and 67 possibly extinct in the wild. The IUCN Red List provides the public with information regarding the conservation status of animal, fungi, and plant species. It divides various species into seven different categories of conservation that are based on habitat range, population size, habitat, threats, etc. Each category represents a different level of global extinction risk. Species that are considered to be critically endangered are placed within the "Threatened" category. As the IUCN Red List does not consider a species extinct until extensive targeted surveys have been conducted, species that a ...

Temminck's Red Colobus
Temminck's red colobus (''Piliocolobus badius temminckii'') is a type of red colobus monkey from the Gambia, Casamance, Guinea-Bissau and northwestern Guinea. It has historically been regarded as a subspecies of the western red colobus (''Piliocolobus badius''), and the Integrated Taxonomic Information System and Mammal Diversity Database both maintain this classification, but many less recent taxonomies classify it as a separate species (''Piliocolobus temminckii''). Temminck's red colobus generally lives in dry deciduous and gallery forests. In Senegal it also lives in savannah. No other red colobus lives in savannah. The use of savannah and open areas may be a recent adaptation to deforestation, since researchers in the 1970s always found Temminck's red colobus in tall, dense forest. Temminck's red colobus living in savannahs often associate with green monkeys, and sometimes also associate with patas monkeys and bushbucks for defense against predators. Temminck's red col ...
