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 ...

Zanzibar Red Colobus
The Zanzibar red colobus (''Piliocolobus kirkii'') is a species of red colobus monkey endemic to Unguja, the main island of the Zanzibar Archipelago, off the coast of Tanzania. It is also known as Kirk's red colobus after Sir John Kirk, the British Resident of Zanzibar who first brought it to the attention of zoological science. It is now classified as an endangered species and in the mid-1990s was adopted as the flagship species for conservation in Zanzibar. The population is still decreasing, and conservationists are attempting to work with the local government to devise a proper, effective strategy to protect the population and habitat. Challenges include the species' habitat, which is limited to the archipelago. The species has been reclassified three times; it was previously in the genus '' Colobus'', then in the genus '' Procolobus'', and later in the genus '' Piliocolobus''.

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 ...

Udzungwa Red Colobus
The Udzungwa red colobus (''Piliocolobus gordonorum''), also known as the Uzungwa red colobus or Iringa red colobus, is a species of the primate family Cercopithecidae that is endemic to riverine and montane forests in the Udzungwa Mountains in Tanzania. It is classified as Vulnerable in the IUCN Red List. Taxonomy The Udzungwa red colobus is a species of the primate family Cercopithecidae. It was first described by German zoologist Paul Matschie in 1900. It has been considered as a sub species of the Western red colobus and Pennant's red colobus by various zoologists. It was re-classified as a separate species in 2001. Morphology The Udzungwa red colobus is a medium-sized monkey with a long tail. The males do not differ much in size fromo the females, but have longer canine teeth and a thicker tail. The body is covered with predominantly black fur with some greyish hairs. The sides of the face and underside are covered with white hairs. It has a tuft of brown or red hair ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semliki Red Colobus
The Semliki red colobus (''Piliocolobus semlikiensis'') is a type of red colobus monkey from central Africa. Historically it has been treated as a subspecies of the Central African red colobus (''P. foai'') but more recent taxonomies generally treat it as a separate species. The Semliki red colobus lives in ironwood forest in the portion of the northeastern Democratic Republic of the Congo between the Semliki River valley and the Ruwenzori Mountains. It may also live in a small area of Uganda Uganda, officially the Republic of Uganda, is a landlocked country in East Africa.

Old World Monkey
Old World monkeys are primates in the family Cercopithecidae (). Twenty-four genera and 138 species are recognized, making it the largest primate family. Old World monkey genera include baboons (genus '' Papio''), red colobus (genus '' Piliocolobus''), and macaques (genus '' Macaca''). Common names for other Old World monkeys include the talapoin, guenon, colobus, douc (douc langur, genus '' Pygathrix''), vervet, gelada, mangabey (a group of genera), langur, mandrill, drill, surili ('' Presbytis''), patas, and proboscis monkey. Phylogenetically, they are more closely related to apes than to New World monkeys, with the Old World monkeys and apes diverging from a common ancestor between 25 million and 30 million years ago. This clade, containing the Old World monkeys and the apes, diverged from a common ancestor with the New World monkeys around 45 to 55 million years ago.

Black-and-white 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 ...

Green Monkey
The green monkey (''Chlorocebus sabaeus''), also known as the sabaeus monkey, is an Old World monkey with golden-green fur and pale hands and feet. The tip of the tail is golden yellow as are the backs of the thighs and cheek whiskers. It does not have a distinguishing band of fur on the brow, like other ''Chlorocebus'' species, and males have a pale blue scrotum. Some authorities consider this and all of the members of the genus ''Chlorocebus'' to be a single widespread species, '' C. aethiops''. Physical description The green monkey is a sexually dimorphic species, with males typically being slightly larger than females. Wild adult males weigh between and measure between , while the females usually weigh between and measure between . Habitat and distribution The green monkey can be found in a wide range of wooded habitats, ranging from very dry Sahel woodland to the edge of rainforests. It is also commonly seen in coastal regions, where known to feed on seashore foods suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dominance Hierarchy
In the zoological field of ethology, a dominance hierarchy (formerly and colloquially called a pecking order) is a type of social hierarchy that arises when members of animal social animal, social groups interact, creating a ranking system. Different types of interactions can result in dominance depending on the species, including Ritualized aggression, ritualized displays of aggression or direct physical violence. In social living groups, members are likely to compete for access to limited resources and mating opportunities. Rather than fighting each time they meet, individuals of the same sex establish a relative rank, with higher-ranking individuals often gaining more access to resources and mates. Based on repetitive interactions, a social order is created that is subject to change each time a dominant animal is challenged by a subordinate one. Definitions Dominance is an individual's preferential access to resources over another based on coercive capacity based on streng ...

Umbrella Species
Umbrella species are species selected for making wildlife conservation, conservation-related decisions, typically because protecting these species indirectly protects the many other species that make up the ecological community (ecology), community of its habitat (the umbrella effect). Species conservation can be subjective because it is hard to determine the status of many species. The umbrella species is often either a flagship species whose Conservation biology, conservation benefits other species or a keystone species which may be targeted for conservation due to its impact on an ecosystem. Umbrella species can be used to help select the locations of potential reserves, find the minimum size of these conservation areas or reserves, and to determine the composition, structure, and processes of ecosystems. Definitions Two commonly used definitions are: * "A wide-ranging species whose requirements include those of many other species" * A species with large area requirements fo ...

Charcoal
Charcoal is a lightweight black carbon residue produced by strongly heating wood (or other animal and plant materials) in minimal oxygen to remove all water and volatile constituents. In the traditional version of this pyrolysis process, called charcoal burning, often by forming a charcoal kiln, the heat is supplied by burning part of the starting material itself, with a limited supply of oxygen. The material can also be heated in a closed retort. Modern charcoal briquettes used for outdoor cooking may contain many other additives, e.g. coal. The early history of wood charcoal production spans ancient times, rooted in the abundance of wood in various regions. The process typically involves stacking wood billets to form a conical pile, allowing air to enter through openings at the bottom, and igniting the pile gradually. Charcoal burners, skilled professionals tasked with managing the delicate operation, often lived in isolation to tend their wood piles . Throughout histo ...

Indicator Species
A bioindicator is any species (an indicator species) or group of species whose function, population, or status can reveal the qualitative status of the environment. The most common indicator species are animals. For example, copepods and other small water crustaceans that are present in many water body, water bodies can be monitored for changes (biochemical, physiological, or behavioural) that may indicate a problem within their ecosystem. Bioindicators can tell us about the cumulative effects of different pollution, pollutants in the ecosystem and about how long a problem may have been present, which Water pollution#Measurement, physical and chemical testing cannot. A biological monitor or biomonitor is an organism that provides quantitative property, quantitative information on the quality of Environment (biophysical), the environment around it. Therefore, a good biomonitor will indicate the presence of the pollutant and can also be used in an attempt to provide additional inform ...
