Cercopithecus sclateri is not known from captivity (one animal at Port Harcourt Zoo, Nigeria) and no ages from the wild have been reported. Other closely related guenons can live to around 20 years of age.
Cercopithicus sclateri is known to raid gardens and farms for food. Some villagers consider it a nuisance.
Negative Impacts: crop pest
Sclater's guenons are one of the most endangered primates in Africa. The combination of an extremely small range in a very populous part of Nigeria have pushed this species to the brink of extinction. The area of Nigeria in which these guenons are found has one of the densest rural populations in all of Africa. The vast majority of the land area has been converted to agricultural use and non-native plantations. Two populations of Sclater's guenons are known to occur in forest reserves, although these reserves provide little protection. A conservation project was started in the Stubbs Creek Forest Preserve in Akwa Ibom State, although it has largely failed to produce results.
Major threats to C. sclateri include habitat destruction and hunting. These, in turn, are driven by the rapidly expanding human populations. In addition, the area in which C. sclateri occurs is located over oil fields, and major oil development is occurring on the Niger delta. Recent surveys, however, are discovering more populations of Sclater's guenons. All of them occur in relatively small, isolated patches of forests. Some small hope is found in the fact that this species is associated with shrines and sacred groves of trees in some villages. The monkeys are protected at these sites because of a taboo associated with killing or eating the monkeys. In some cases, they are thought of as protectors of the sacred sites. However, the younger generation may be losing some of these inhibitions to killing these monkeys.
US Federal List: no special status
CITES: appendix ii
IUCN Red List of Threatened Species: vulnerable
Cercopithecus sclateri, like the other members of its superspecies group Cercopithecus (cephus), has a striking facial pattern that is hypothesized to be used in communication relating to reproduction. Specifically, the cheek patches and nose may be important in signalling. This pattern, in conjunction with very fast and complex head weaving, may serve important roles in maintaining relationships with other members of a group. Sexual selection may play a role in the evolution of facial pattern in this species. The highly colored tail is probably also used to communicate with conspecifics.
Within the genus Cercopithecus, 22 different vocalizations have been described. These include noises to maintain group cohesion, warning signals, and loud noises emitted by males
Tactile communication is important in all primates. Grooming behaviors typically indicate close relationships between individuals. Mothers communicate with their young through touching, as do mates. Physical aggression often occurs, especially between rival males.
Communication Channels: visual ; tactile ; acoustic
Perception Channels: visual ; tactile ; acoustic ; chemical
Cercopithecus sclateri is hunted for food in virtually all of its range, although hunting is not an important activity in this area because of the relative lack of game. In addition, the possibility that ecotourism could become an important part of the conservation plan for this species has been proposed due to its proximity to currently visited areas in Nigeria.
Positive Impacts: food ; ecotourism
The most important role of C. sclateri is probably as a seed disperser. Their cheek pouches may facilitate the spread of seeds. It is unlikely that this species, because of its rarity, is important as a prey item.
Ecosystem Impact: disperses seeds
Cercopithecus sclateri, like most small guenons, is probably predominantly a frugivore. Other important components of guenon diets include insects, flowers and leaves. They are omnivorous and because they inhabitat some villages and towns with little or no forest cover, they raid gardens and farms for food. The only specific reference to a species which is eaten by these guenons is the red silk cotton tree, Bombax buonopozense.
Animal Foods: birds; reptiles; eggs; insects
Plant Foods: leaves; roots and tubers; seeds, grains, and nuts; fruit; nectar; flowers
Primary Diet: herbivore (Frugivore )
Sclater's guenon, Cercopithecus sclateri, is restricted to floodplain forests between the Niger river and the Cross river in southeast Nigeria. Eleven small populations have been confirmed to exist. Populations are known to exist in the states of Akwa Ibom, Enugu, Imo, Abia and Cross River State. The localities known for this species include Utuma, Stubbs creek, Akpugoeze, Osomari, Lagwa, Blue river, Enyong creek/Ikpa river.
Some authors have speculated that C. sclateri may be a hybrid between Cercopithecus erythrotis, which occurs on the eastern side of the Cross river in Nigeria and Cameroon, and Cercopithecus erythrogaster which occurs on the western side of the Niger delta in Nigeria. Several authors, however, agree that C. sclateri deserves full specific status.
Biogeographic Regions: ethiopian (Native )
Cercopithecus sclateri occurs in moist tropical forests and swampy floodplain forests. These are low elevation habitats along the coast of Nigeria. Although this species' natural habitat is probably secondary growth and primary forest, it seems to be surviving in some extremely degraded habitats. An important habitat for this species is Igbo villages and their sacred tree groves, which are mostly surrounded by non-native tree plantations and agricultural areas. In one town, Lagwa (Imo state), all the patches of forest which the monkeys formerly inhabited have been cut down, leaving the animals to inhabit villages, where they steal food from gardens and farms.
Cercopithecus sclateri is a member of the Cercopithecus (cephus) superspecies group. Members of this group occur in primary rainforest like most of the other species of guenons, but also occur in secondary forests more often than other guenon species. In addition, the closely related species in this group seem to prefer the lower levels of the canopy and sometimes come to the ground.
Habitat Regions: tropical ; terrestrial
Terrestrial Biomes: forest ; rainforest
Wetlands: swamp
Other Habitat Features: agricultural
Sclater's guenon, like all guenons, is a very colorful monkey with a complicated facial pattern. The body is overall a dusky gray color with some greenish tinge on the back. The tail is very long (about one-half the total length) and is reddish colored on the ventral proximal part, gradually becoming white distally and ending in a black tip. The muzzle is brownish pink with a creamy white nose spot (above the nostrils on the bridge of the nose). The face is adorned with three major hair patches. The crown and cheek patches are yellow mixed with black. In addition, there is a large white throat patch extending almost to the ears. The ears have prominent white tufts. Finally, black temporal bars extend past the ears and meet at the back of the head.
Cercopithecus sclateri, along with the other members of their superspecies group, is among the smaller guenons. The species is somewhat sexually dimorphic. Females weigh about 2.5 kg whereas males weigh about 4.0 kg. All guenons, including C. sclateri, have sexually dimorphic canines. In addition, they have longer hindlimbs than forelimbs. Finally, a distinguishing characteristic that helps to separate all guenons from the colobus monkeys is the presence of cheek patches.
Range mass: 2.5 to 4.0 kg.
Range length: 80 to 120 cm.
Other Physical Features: endothermic ; homoiothermic; bilateral symmetry
Sexual Dimorphism: male larger
Cercopithecus sclateri may become wary of humans in response to hunting pressure. Other specific information on the predators of these guenons is not available. It is likely, however, that they do fall prey to large snakes, raptors, and mammalian carnivores.
Known Predators:
There is little information available on reproduction in C. sclateri. However, members of the genus are typically polygynous, and it is reasonable to assume that C. sclateri is as well. The mating system of their superspecies group differs from other guenons in the decreased importance of single male groups. Instead, females seem to make up the core group and they often travel together without a male. Female independence seems to be very important, as females defend territories from other groups. Males in the C. (cephus) group, including C. sclateri probably practice opportunism with respect to copulation with females rather than guarding groups of females as do other members of the genus. Males signal to females prior to mounting them. They do this with head weaving movements which have been hypothesized to be an important courtship ritual used to reassure females with whom a male wants to mate. In addition, these head weaving movements may have contributed to the radiation of the complex facial patterns of C. sclateri and other species in the C. (cephus) group.
Mating System: polygynous
Very little information is available on the reproduction of C. sclateri because the species was recently discovered. The first observations of these animals in the wild occurred in 1988. This delayed discovery may be due in part to the fact that these monkeys inhabit an area of Nigeria that has long been avoided by biologists and conservationists. In this part of Nigeria, there is a high human population, and a lack of natural areas in which to study animals.
Generally, within the genus Cercopithecus, mating season corresponds to the time of highest food availability. For many species this occurs in July, August, and September, however, rainforest species, potentially including C. sclateri, exhibit more flexibility in this regard. Gestation is around 6 months with birth occurring during the months of December, January, or February. Young weigh approximately 400 g at birth, and cling to the mother's ventrum. The period of nursing is not known for this species, but like most Cercopithecines, it is probably complete by about 9 months of age. Females produce their first young at about 5 to 6 years of age.
Breeding interval: Intervals one to five years reported for species of Cercopithecus.
Breeding season: No information reported for C. sclateri. The breeding season peaks for most species of guenons in the months of July, August and September.
Range number of offspring: 1 to 2.
Average gestation period: 5 months.
Range age at sexual or reproductive maturity (female): 5 to 7 years.
Key Reproductive Features: iteroparous ; seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; fertilization ; viviparous
Little is known about parental investment in C. sclateri. The species is poorly studied, but probably resembles other Cercopithecine monkeys. A young guenon rides on its mother's ventrum, clinging to her fur and entwining its tail with hers. As in most Cercopithecines, parental care is probably provided primarily by the mother. She nurses, carries, and grooms her offspring. Infants are generally dependent upon their mother for all forms of care. Cercopithecine young typically remain with their mother for some time after weaning. It is not uncommmon for rank of mothers to affect the dominance standing of their offspring. The role of males in the parental care of this species has not been reported.
Parental Investment: no parental involvement; altricial ; female parental care ; pre-fertilization (Protecting: Female); pre-hatching/birth (Provisioning: Female); pre-weaning/fledging (Provisioning: Female, Protecting: Female); pre-independence (Provisioning: Female); extended period of juvenile learning

Die Nigeria-Blaumaulmeerkatze (Cercopithecus sclateri) ist eine Primatenart aus der Gattung der Meerkatzen (Cercopithecus) innerhalb der Familie der Meerkatzenverwandten (Cercopithecidae).
Nigeria-Blaumaulmeerkatzen zählen zu den kleineren Meerkatzen, Weibchen erreichen ein Durchschnittsgewicht von 2,5 Kilogramm und Männchen von 4 Kilogramm. Ihr Fell ist an der Oberseite olivgrün und an der Unterseite grau gefärbt. Das blaue Gesicht ist von weißgelben Haarbüscheln an den Backen umgeben, die Oberseite des Kopfes ist gelb und die Kehle weiß gefärbt. Die Ohren tragen auffällige weiße Haarbüschel.
Nigeria-Blaumaulmeerkatzen sind im südlichen Nigeria östlich des Nigers endemisch. Ihr Lebensraum sind Sumpfgebiete oder in der Nähe von Flüssen gelegene Wälder.
Diese Primaten sind tagaktive Baumbewöhner. Sie leben in Gruppen von bis zu 30 Tieren zusammen, die wie bei allen Meerkatzen Haremsgruppen darstellen. Das heißt, diese Gruppen bestehen aus einem Männchen, mehreren Weibchen sowie dem dazugehörenden Nachwuchs. Die Nahrung der Tiere besteht vorwiegend aus Früchten, vermutlich nehmen sie wie andere Vertreter ihrer Gattung auch Blätter, Samen und Insekten zu sich.
Die Nigeria-Blaumaulmeerkatze galt bereits als ausgestorben, ehe sie 1988 wiederentdeckt wurde. Heute ist die Population auf fünf kleine Restgruppen zersplittert, die allesamt unter 250 Exemplare ausmachen. Zwei dieser Populationen sind geschützt, da sie von der dortigen Bevölkerung als heilig betrachtet werden, die anderen waren zum Teil intensiver Bejagung ausgesetzt. Ihr Siedlungsgebiet ist heute größtenteils geschützt, und somit vor Waldrodungen gesichert, dennoch gilt die Art, auch aufgrund der Zersplitterung ihres kleinen Verbreitungsgebietes laut IUCN als stark gefährdet (endangered). Im Cross-River-Nationalpark und südlich des Oguta-Sees leben die Nigeria-Blaumaulmeerkatze in geschützten Gebieten.

Sclater's guenon (Cercopithecus sclateri), also known as Sclater's monkey and the Nigerian monkey, is an Old World monkey that was first described by Reginald Innes Pocock in 1904 and named after Philip Sclater. It is an arboreal and diurnal primate that lives in the forests of southern Nigeria. It should not be confused with the closely related species, the white-throated guenon (Cercopithecus erythrogaster), which occurs in Nigeria and Benin. Sclater's guenon was formerly classified as a subspecies of the red-eared guenon (C. erythrotis).[2]
The diet of Sclater's guenon is unknown. The species is likely primarily a frugivore that supplements its diet with other plant parts and insects, based on data from closely related species.[3]
Sclater's guenon was thought to be nearly extinct until the late 1980s. The species is now known to occur in several isolated populations between the Niger and Cross Rivers in southern Nigeria. This region falls in the Guinean Forests of the West Africa biodiversity hotspot.
The species does not occur in any officially protected areas, but three populations of Sclater's guenon are known to be protected by local people who consider the monkeys to have sacred status. Mostly because of hunting and habitat fragmentation and loss, thus increasing population isolation and decline, Sclater's guenon is listed as a vulnerable species.[2]
Sclater's guenon is known to occur in captivity only at the [http://www.cercopan.org Centre for Education, Rehabilitation, and Conservation of Primates and Nature in Cross River State, Nigeria.

Cercopithecus sclateri är en primat i släktet markattor som förekommer i sydöstra Nigeria.
Denna markatta har påfallande mönster i ansiktet som påminner om en mask. Området kring munnen är ljus eller mörk men näsan är alltid rosa till vitaktig. I ansiktet finns tre tydliga skägg, ett under hakan, ett över kinden och ett på pannan. Dessutom har öronen vita kanter. För övrigt är pälsen gråbrun med en grönsvart skugga på ryggen. Kroppslängden varierar mellan 80 och 120 cm. Vikten ligger mellan 2,5 och 4,0 kg.[2]
Utbredningsområdet ligger huvudsakligen i Nigerflodens delta i sydöstra Nigeria. Arten vistades ursprungligen i tropiska regnskogar. På grund av skogsavverkningar lever den nu delvis i nyanlagda skogar.[1]
Individerna lever i flockar som ibland ledas av en dominant hanne men i motsats till flera andra markattor kan flocken även bestå av flera hannar och honor. Vanligen vistas gruppen nära andra markattartade apor, oftast mustaschmarkatta (C. cephus). Reviret kan vara 130 hektar stort men är vanligen mindre liksom hos andra markattor. De rör sig på marken och klättrar i växtligheten. Födan utgörs främst av frukter och insekter och de äter även blad.[2]
Hur arten fortplantar sig är inte helt utredd. Antagligen får honor sina ungar när utbudet av föda är störst (liksom hos andra markattor) men studier tyder på att arten är mera variabel. Oftast får honor sina ungar (en eller två per kull) efter 6 månaders dräktighet mellan december och februari. Ungdjuret väger i början cirka 400 gram. Efter 5 till 6 år kan honor ha sina första ungar.[2]
Livslängden antas vara liksom hos andra markattor, alltså cirka 20 år.[2]
Speciella naturliga fiender är inte kända men troligen faller en och annan individ offer för predatorer som lever i samma region (större ormar, rovfåglar och rovdäggdjur).[2]
Arten lever i en befolkningstät region av Nigeria och den hotas främst av habitatförstöring när skogen omvandlas till odlingsmark och boplatser. Cercopithecus sclateri jagas i viss mån men jakttrycket är inte lika stort som för större primater. IUCN uppskattar att populationen minskade med 30 procent under de senaste 27 åren och listar arten som sårbar (VU).[1]

Ареал
Мартышка Склейтера[источник не указан 400 дней] (лат. Cercopithecus sclateri) — вид приматов из семейства мартышковых. Была описана Реджиналдом Пококом в 1904 году и названа в честь Филипа Склейтера. Мартышка Склейтера ранее считалась подвидом рыжеухой мартышки.[1]
Шерсть тёмно-серая, на спине зеленоватая. Хвост очень длинный, сверху красноватый, более светлый к концу, однако самый кончик хвоста чёрный. Мордочка коричневато-розовая, кончик носа более светлый. Шерсть на макушке и щеках длинная, включает жёлтые волоски. Шерсть на горле и на ушах светлая.
Это одна из самых маленьких мартышек. Выражен половой диморфизм: средний вес самок составляет 2,5 кг, средний вес самцов составляет около 4 кг.[2]
Встречается на юге Нигерии. Вид не следует путать с краснобрюхой мартышкой, которая водится в Нигерии и Бенине.
Дневное животное, проводящее почти всё время на деревьях. В рационе преимущественно фрукты, а также другая растительная пища и мелкие животные.[3]
