Overall body size of males tends to be larger than females due to prolonged and accelerated growth. Oates JF, compiler. Problems of distribution and adaptation of the African monkeys. Inter-group encounters are typically agonistic but rarely physical and serve to assist in group resource defense (Chism et al. Anim Behav 62(6): 1047-58. Open country is the domain of the patas monkey, but they adapt well and tolerate several types of habitat (Tappen 1960).

Adaptive aspects of social structure in Erythrocebus patas. fill out the account information below. [13], The common patas monkey feeds on insects, gum, seeds, and tubers, a diet more characteristic of much smaller primates. Suborder: Haplorrhini Proies inhabituelles pour le patas dafrique de louest (Erythrocebus patas patas). (Barbara B. Smuts, et al., 1987; Honolulu Zoo, 2005; Nowak, 1999). They may also have some positive impact on populations of organisms which prey upon them. Reaching speeds of 55km/h (34mph), it is the fastest runner among the primates. Loy J, Argo B, Nestell GL, Vallett S, Wanamaker G. 1993. 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 2013), 60% of time spent on the ground (Mittermeier et al.

Patas exhibit a low frequency of contact calling between individuals which may be as a result of the open nature of their habitat which facilitates visual contact instead (Nakagawa 1992). terms of usage. Primates 30(1): 27-34. . Cameroonian observations put the home range at 2.66 to 4.4 km (1.03 to 1.7 mi) (Nakagawa 1999). When intergroup conflicts do occur, females and young are more active than males. In captivity, this model of the sole male at the edge of the group holds, with the male aloof and indifferent to intra-group social interactions (Hall & Mayer 1967). 2003; Chism et al. Int J Primatol 7(1): 83-107. Because these animals are social, it is likely that visual signals such as body postures and facial expressions play important roles in communication. WebCommon patas monkeys have several distinct alarm calls that warn members in the group of predators. Christopher Bonadio (author), University of Michigan-Ann Arbor, Phil Myers (editor), Museum of Zoology, University of Michigan-Ann Arbor. Topics in length, excluding the tail, which measures 30 in. These subspecies are disputed and may only represent geographical divisions of the species (see Groves 2001; Grubb et al. 1974. Ants and thorn trees (Isbell 2013; Isbell et al. Int J Primatol 7(1): 49-81. In Cameroon, the patas monkey has been studied in the African Sahel, a semi-desert ecosystem with annual rainfall of less than 508 mm (20 in) and a prolonged dry season (Tappen 1960). The most important trait of the Sahel is its precipitation which is low and seasonal (Gartlan 1974). Within their range, populations are sometimes spotty with gaps where no patas are to be found, however the greatest population densities are in west central Africa (Gartlan pers. Supplantation by a challenger male is sometimes followed by a short-lived multi-male polygynous mating system in which several males are actively breeding within a group (Ohsawa et al. Sometimes the male will leave his natal group with a brother, a kin relation which may help them both survive (Chism 1999). Males may have offspring with more than one female. York A, Rowell TE. The age at first conception in females in both the wild and in captivity is approximately 2.5 years resulting in the first birth at around three years of age (Chism et al. The mountain Nuba people and tribal groups also hunt patas monkeys. Causes and consequences of single-male and multimale mating in free-ranging patas monkeys, Erythrocebus patas. Indiscriminate response to infant calls in wild patas monkeys (Erythrocebus patas). Patas monkeys avoid areas with dense cover, perhaps due to exposure to predators. 1978. Gland (Switzerland ): IUCN/SSC Primate Specialist Gp. In: Kondo S, Kawai M, Ehara A, Kawamura S, editors. Therefore, it is difficult to reliably estimate gestation periods in wild patas monkeys based on captive specimans. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. The Patas monkeys cheeks are able to contain as much food as their stomachs can. A primate radiation: evolutionary biology of the African guenons. These pairings may allow unfamiliar patas to assess one anothers reproductive fitness and allow the pair of monkeys to size each other up (Harding & Olson 1986). in length. Bercovitch F. 1996. The mountain Nuba people and tribal groups also hunt patas monkeys. Many farmers and plantation owners shoot these monkeys when they raid their crops. Patas monkeys are collected and sold as pets or they are sold to medical research institutions. Over 1000 patas monkeys are collected per year. WebPatas monkeys have a shaggy, reddish-colored coat. 1981). In one study in Kenya, the patas diet was observed to be almost two-thirds gum and arthropods, which would make them by far the physically largest primarily exudativorous or insectivorous primate (Isbell 1998). This is the ultimate Duke Nukem soundboard, with new stuff added as I find it. The bright blue color of the patas scrotum appears to play some role in competition for access to females, but its color exhibits no correlation with season, age, or health (Bercovitch 1996). For the first several months, the predominant posture of an inactive mother with a young infant is that of cradling which starts to steadily decrease in the third month. 1973. 80 p.

Many farmers and plantation owners shoot these monkeys when they raid their crops. In one study, patas were demonstrated to prefer grassland in the wet season and they preferred to sleep in woodlands to avoid predators (Nakagawa 1999). Grasses play a surprisingly unimportant dietary role as one would expect a resource as available as grass to comprise at least some part of patas subsistence (Chism & Rowell 1988). In a long term study, the mortality rate of infants and one year-old juveniles averaged 20% (Nakagawa et al. Am J Primatol 1:371-8. The purpose of the all-male patas group appears to be to provide safety for young or infirm males and for protection against predators and other threats (Ohsawa 2003). Rainfall in these areas averaged 630 mm (24.8 in) per year with the most rain falling between April and November and the least in January (Chism & Rowell 1988). Carlson A, Isbell L. 2001.

Sodeinde OA, Soewu DA. the region of the earth that surrounds the equator, from 23.5 degrees north to 23.5 degrees south. These primates occupy the dry savannah landscapes of Tropical Africa. 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). Seuss. these monkeys have a greyhound-like build.) WebThe meaning of PATAS is a reddish colored long-tailed monkey (Erythrocebus patas) of West Africa called also hussar monkey. Folia Primatol 5: 213-36. Identification Numbers. Activity budget and diet of patas monkeys in Kala Maloue National Park, Cameroon: a preliminary report. Typically, primates that live in savanna and dry forest are less endangered due to expansive distributions (Oates 1996). 1981. In captivity, the average gestation period for a female patas monkey is 167 days (Sly et al. One male is present through the year with a group of females but other males infiltrate the group during the mating season to breed with group females (Harding & Olson 1986; Carlson & Isbell 2001). Grooming plays an important role in patas social organization and can indicate hierarchies within a group as well as relationships between individuals doing the grooming (Rowell & Olson 1983). This nursing is merely a supplemental food source as the infant is quickly learning how to forage on its own. 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.

SDZWA Library Mission: To provide outstanding information resources and services to advance knowledge in animal and plant care and conservation, inspire passion for nature, ignite personal responsibility, and strengthen our organizations capacity to save species worldwide. Males are considerably larger than females, which average 19 in. However, intergroup interactions may occur when several groups drink from the same water hole. This website works best with modern browsers such as the latest versions of Chrome, Firefox, Safari, and Edge. Folia Primatol 20: 331-50. [14], Variation in the female social structure of patas monkeys has been observed across different populations. Give a listen. No apes sounds here, various smaller Monkeys recorded in nature. Patas exhibit a large degree of sexual dimorphism with adult males weighing 12.4 kg (27.3 lb) and adult females weighing 6.5 kg (14.3 lb) on average (Galat-Luong et al. Finally, they have also been seen in the zone of flooding in the delta of the Senegal River. 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).

English common names for subspecies and species of African primates. Folia Primatol 64(1-2): 62-8. 1984). Mating and residence patterns of male patas monkeys. There is evidence of post-conflict reconciliation among patas females with increases in contact between former adversaries following agonistic interactions (York & Rowell 1988). All genders and ages participate, though males only occasionally engage in this activity. 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. Primates of the world; distribution, abundance, and conservation. 1965). Patas rely on an adaptive silence and prefer not to give away their locations to predators (Hall 1967). $0.99 Female patas monkeys nurse and care for their young until they become independent. The Animal Diversity Web team is excited to announce ADW Pocket Guides! In the meantime, we welcome readers to send updates for consideration. The hierarchy of patas females remains somewhat static once established and is maintained through submissive and aggressive actions between the patas females. Large home ranges also make defense quite difficult (the day range of this species is 4,330m +/-1,520m). This behavior may also be related to an altruistic relationship between adult females (Nakagawa 1998). Baltimore and London: The Johns Hopkins University Press. 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). This is especially true of species with similiar age and sex, and perhaps among kin. East Hampton (NY): Pogonias Pr. The diet consists mainly of fruits and insects but also includes leaves, roots, and bird eggs. Seattle (WA): Univ Washington Pr. See also Tropical savanna and grassland biome. Patas vocalize infrequently and tend to move quietly (Chism & Rowell 1988). Wolfheim J. They have a narrow body, long legs for quadrupedal locomotion, and a prominent rib cage. Cambridge (UK): Cambridge Univ Pr. Primate Factsheets: Patas monkey (Erythrocebus patas) Conservation . Folia Primatol 69(2): 93-9. Although data are lacking for this species, it is likely that the nursing period extends for several months, based upon that seen in other, similar-sized guenons. They have a huge range of about 40 square kilometres and are on the move practically all the time, snacking as they go. [6] However, more recent studies haave found this interpretation of Cercopithecus to be paraphyletic, and thus many species in Cercopithecus have since been reclassified to numerous new genera and species, with C. aethiops moved to Chlorocebus and C. lhoesti to Allochrocebus. Am J Primatol 4: 23-32. In addition, wild patas monkeys typically give birth during the day which may be an adaptation to reduce the risks associated with nocturnal predators. Isbell L. 1998. The ventrum is white, as are legs and feet. This monkey gets its name from its loud vocalizations, which sound like a bark or a roar. Encyclopedia Britannica, "britannica.com" (On-line). On at least one occasion in Cameroon, patas females of one group were observed to kidnap an infant from a different group, allomother it for a while and eventually abandon it (Nakagawa 1995). The reason young males leave their natal group is also contested. The smart red coat and New York: AR Liss. - I agree to the privacy policy and the 1984). [17], Young males have been observed to leave their natal groups anywhere from two to four years of age. Although no specifically recorded for these monkeys, it is likely that some scent cues are used in reproduction. The adult females in the group initiate movement of the group with the male following their lead. There is evidence that the smaller the patas group, the higher the instance of allogrooming (Chism & Rogers 2002). Vegetation is made up mostly of grasses, the height and species diversity of which depend largely on the amount of moisture available. Erythrocebus patas. Nakagawa N. 1995. 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). Chism J. J Zool 148: 15-87. It also has been introduced to Puerto Rico. It has been suggested that the reason that patas move more than many Old World Monkeys and the reason why their morphology is so well suited to movement, is their diet, which is widely dispersed but high in quality (Isbell 1998). 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. Patas monkeys are omnivorous. Anim Cogn 1(1): 65-9. Patas do the majority of their feeding on the ground, with up to 85% of feeding activity occurring terrestrially (Gartlan 1974). 1981). The genus status of the species has previously been in flux. Patas polygynous group size is quite variable, from 20 to as large as 76 individuals (Enstam et al 2002; Ohsawa 2003). WebThe Patas Monkey [1] (Erythrocebus patas), also called the Hussar Monkey or Wadi Monkey is a terrestrial monkey distributed in semi-arid areas of West and East Africa.. Patas monkeys have shaggy reddish fur. Depending on the victor, either the resident male is removed from his position as the sole male or the challenger remains peripheral. Journal of Zoology, 161: 49-63. Allomothering may also serve to strengthen social interactions and group cohesion. Species: E. patas. Due to their large numbers, this practice has not as of yet substantially affected their numbers. Download: Click on icon next to each track or the 'FULL Synapomorphy of the Bilateria. Accessed Loy J. Nowak, R. 1999. 1967. Originally suggested to be a submissive/appeasement signal, this display has been argued not to convey such a message. Different alarm calls are given by different group members (i.e. The image has been cropped to focus attention on the specified behavior. One male remains as the resident male and chases other males away. having body symmetry such that the animal can be divided in one plane into two mirror-image halves. WebThe Patas monkey or Erythrocebus patas grows 24 in to 34 in. The water sources in the Sahel areas are vitally important for all of the mammals living there, including the patas monkey. The other type is that of all-male groups although occasionally mixed-sex groups with two adult males have been known to occur (Hall 1965; Struthsaker & Gartlan 1970; Gartlan 1974). Nakagawa N. 1989. There are also instances in which patas were observed catching and eating fish out of evaporating natural pools in Senegal (Galat-Luong 1991). p 489-90.
