At present, it is not obvious what the benefits of allomothering are, although they may be related to social hierarchy based on who receives allomothering and who does the allomothering (Muroyama 1994; Nakagawa 1995). Although no specifically recorded for these monkeys, it is likely that some scent cues are used in reproduction. This variation may be dependent on food resources, as conflict between individuals is often a result of competition for limited resources. The patas male measures, excluding the tail, 600 to 875 mm (23.6 to 34.4 in) and the female measures 490 mm (19.3 in) on average (Rowe 1996). Vocalizations have been recorded under many different circumstances. Etter HF. Patas do the majority of their feeding on the ground, with up to 85% of feeding activity occurring terrestrially (Gartlan 1974). The male matures slightly later and can sire offspring at four years old, but rarely is able to do so due to his inability to access females (Rowell & Chism 1986). Hunters kill patas monkeys for meat in the Ivory Coast. In terms of intergroup relations, conspecifics are not friendly. p 23-37. The NonHuman Primates. Some individuals have been seen in moist woodlands. The tail curves down while on the ground, but is raised when on a narrow surface such as a tree branch, most likely for balance (Hall 1965; Hall et al. 2021 San Diego Zoo Wildlife Alliance. Advert was interrupted. gonochoric/gonochoristic/dioecious (sexes separate), post-independence association with parents, American Journal of Physical Anthropology, Walker's Mammals of the World, Sixth Edition, Primates of the World: Distribution, Abundance, Conservation, Max Planck Institute for Demographic Research, http://www.honoluluzoo.org/patas_monkey.htm. Patas monkeys avoid areas with dense cover, perhaps due to exposure to predators. [19][20], "Patas" redirects here. these monkeys have a greyhound-like build.) 2013), Males are socially peripheral, rarely receiving affiliative behavior from females within the group (Nakagawa 1992), Single-male, multi-female groups most of the year (Hall 1966; Isbell 2013), Not a "harem" system, as in the hamadryas baboon (Mittermeier et al. mushrooms), Male may threaten others that come near a female of interest, Group members (adult females and some young adults) harass the adult male during copulation attempts; including open-mouthed threats, lunges, and hitting or touching the male's face (Carlson and Isbell 2001; Hall 1966), Yawn; known as a threat-yawn, displays large canine teeth, Stare; fully facing opponent with a directed prolonged gaze, mouth held open with head slightly lowered, Slap; strike out with a hand toward another, "Surprise" attack; individual pounces on the back of another and delivers a quick bite, Male group leaders rarely initiate attacks on group members, Calls often quiet, especially compared to baboons (Hall 1966; Isbell personal communication; Mittermeier et al. It appears that all-male groups are typically smaller than the polygynous groups with Cameroonian all-male group observed with 15 to as few as two individuals (Struhsaker & Gartlan 1970; Ohsawa 2003). [citation needed] During periods when females are not receptive, relatively stable groups with one adult resident male and several females are the norm. Per Track:
Patas monkeys are quadrupedal and their terrestrial locomotion is extremely quick for a primate, with a maximum speed of approximately 55 km per hour (34.2 mph) reported (Hall 1965). Their especially long forelimbs facilitate this high running speed which provides an avenue of escape from predators (Etter 1973). There is some debate as to the easternmost extent of their territory with some extending their range into Somalia (Kingdon 1971). Communication in all primate species is complex. 1983. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Traditionally, only one species of patas monkey has been recognized but up to four subspecies have been proposed, E.p.baumstarki, E.p.patas, E.p.pyrrhonotus, E.p.villiersi. 2003). Sly DL, Harbaugh SW, London WT, Rice JM. It is found in many parts of central, western, and eastern Africa. Seattle and London: University of Washington Press. Overall, wet season observations of Ugandan patas recorded markedly rare drinking behaviors (Hall 1965). Per Track:
1987. WebPatas Monkey. Different alarm calls are given by different group members (i.e. During the rainy season, it will eat plant materials including fruits, flowers, leaves, stems and gums as well as insects, other animal material, and fungi (Nakagawa 1989; Hall 1965). WebPatas monkeys, also known as hussar monkeys, wadi monkeys, nisnas, and singe rouge, are monkeys of the Cercopithecidae family. Calls often quiet, especially compared to baboons (Hall 1966; Isbell In: Altmann S, editor. Higher rates of conflict over dense, but limited, food, such as fruit bushes, is associated with more stable, well defined dominance hierarchies than habitats with more diffuse resources, such as insects. All fields are required, VERIFICATION EMAIL
Chicago: Univ Chicago Pr. The midfacial region (skull) of the male patas monkey is hypertrophied compared to females. The ADW Team gratefully acknowledges their support. Social monitoring in a primate group: the relationship between visual attention and hierarchical ranks. in length. Conservation information last updated in 2006 follows, for comparison: According to Oates (1996), patas were assigned to the lowest threat level among African primates and were considered to be a low risk species. The patas monkeys diet varies with changes in food availability due to the seasonality of its environment. 1965. Am J Primatol 45(4): 381-98. 1984). Traff Bull 18(1): 35-40. Ants and thorn trees (Isbell 2013; Isbell et al. This may indicate weakening of matrilineal ties, rather than male aggression, as the main reason juveniles disperse from their natal group. Typically conception occurs in the summer wet season and births occur in the winter dry season (Struhsaker & Gartlan 1970; Nakagawa et al. They occur from Senegal on the west coast of Africa all the way east to the Sudan and south to Lake Tanganyika, one of Africas Great Lakes (Tappen 1960). However, it is likely that patas monkeys fall victim to the standard predators of the subsaharan African savanna: lions, cheetah, African hunting dogs, jackels, brown hyenas, spotted hyenas, snakes, and raptors. 1984; Isbell 1998; Nakagawa 2008), Up to 7 males associated with a single group in one mating season, one study (Carlson and Isbell 2001), Females remain in natal group throughout life, typically (Isbell 2013), Larger groups may have multiple males (Chism and Rogers 1997), Resident male does not appear to have a reproductive advantage (Chism and Rogers 1997), All male groups, typically composed of dispersing males (Chism and Rogers 1997), Composition fluctuates; may not be stable groups, Fluctuates widely over time (Isbell 2013; Isbell et al. the kind of polygamy in which a female pairs with several males, each of which also pairs with several different females. 1988). The nostrils are narrow, close together, and pointed downward (catarrhine). The common patas monkey (Erythrocebus patas), also known as the wadi monkey or hussar monkey, is a ground-dwelling monkey distributed over semi-arid areas of West Africa, and into East Africa. Volume one: behaviour. These subspecies are disputed and may only represent geographical divisions of the species (see Groves 2001; Grubb et al. cited in Wolfheim 1974). 1967. This may assist the infant in its suckling posture and to keep it warm (Chism 1986). It also has been introduced to Puerto Rico. reproduction in which fertilization and development take place within the female body and the developing embryo derives nourishment from the female. In 1975, limited evidence was presented in favor of single-mount copulations as the species-typical pattern for patas. A case of infant kidnapping and allomothering by members of a neighbouring group in patas monkeys. Captive lifespan may reach as much as 24 years. 1987. In some areas in Sudan, they feed in pineapple plantations, and they also destroy cotton plants by eating the flowers. Draft copy, National fish and wildlife laboratory, Washington DC 2: 438-48. A terrestrial biome. uses smells or other chemicals to communicate. Captive patas monkeys have confirmed these patterns. fill out the account information below. Galat-Luong A. Colin Groves first argued the species was closely related to Cercopithecus aethiops in 1989, based on anatomical morphology. There are also instances in which patas were observed catching and eating fish out of evaporating natural pools in Senegal (Galat-Luong 1991). Inter-group encounters are typically agonistic but rarely physical and serve to assist in group resource defense (Chism et al. The appearance of patas monkeys contributes to the use of alternative names such as red guenons, Hussar monkeys, military monkeys, and dancing red monkeys. This hierarchy is not as well defined or as firm as those of other Cercopithecines and it is likely that the patas monkey dominance hierarchy is not kin-based (Chism & Rogers 2002). This displacement occurs typically at around three years of age and they may remain solitary or in all male groups until they are fully grown at around five years of age (Chism et al. 1983). Journal of Zoology, 161: 49-63. incisors are spatulate, canines conspicuous, and molars are bilophodont. Loud chutter is the alarm call associated with baboons, domestic dogs, jackals and wildcats. Non-territorial, though intolerant of other groups (Isbell 2013), Affiliative Behaviors (from Hall 1966 unless otherwise noted), Play (from Hall 1966 unless otherwise noted), Aggression (from Hall 1966 unless otherwise noted). Just
Wolfheim J. During the course of this association, the male and female patas monkey will copulate. Int J Primatol 23(1): 85-104. She also may drool and curl her tail (Chism et al. [15], Conflict among females has also shown the presence of recognition among matrilineal relatives. In Cameroon, exportation requires a permit. animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. Dominance hierarchies are not apparent among patas monkey groups. They grow up to 90 centimeters tall and weigh between four and thirteen kilograms (8.8 to 28.6 pounds). generally wanders from place to place, usually within a well-defined range. In addition, wild patas monkeys typically give birth during the day which may be an adaptation to reduce the risks associated with nocturnal predators. Christopher Bonadio (author), University of Michigan-Ann Arbor, Phil Myers (editor), Museum of Zoology, University of Michigan-Ann Arbor. Hall KRL, Beolkins RC, Goswell MJ. They are found north of Africas equatorial forests and south of the Sahara Desert, with a distribution ranging from western Senegal to Kenya and northern Tanzania, although they are found at high Search in feature 2003. Primate Factsheets: Patas monkey (Erythrocebus patas) Taxonomy, Morphology, & Ecology . will be sent to address. terms of usage. In captivity, the average gestation period for a female patas monkey is 167 days (Sly et al. However, observations of wild patas monkeys has shown young males leaving the group in which they were born without any aggressive behavior from the adult male. Supplantation occurs when a male from another group challenges the single male and may be accomplished through fighting and chasing (Ohsawa 2003). Female primates: studies by women primatologists. [10] 1998b; Nakagawa 2008), Some wild and managed care groups form nearly a linear dominance hierarchy (Loy et al. Other names: Patas, red guenon, red monkey, military monkey, nisnas, Ar patas, Ar red, black-nosed patas, west African patas, west African red monkey, blue nile hussar monkey, dancing red monkey, nile patas, Ikoma patas or red hussar monkey; engabwor (Ateso); cercopitheque patas, le singe rouge, patas (French); husarenaffe (German); elwala (Karamajong); naggawo (Luganda); ayom (Lwo); akahinda (Runyoro); husarapa or patasapa (Swedish).
