E.F .Segal), pp. Accordingly, singly-caged adults of both sexes were paired with same-sexed partners after rank relationships had been established during a period of non-contact familiarization (Reinhardt, 1989). [15] This natal coat may indicate to others the status of the infant, and other group members treat infants with care and rush to their defense when distressed. Viktor Reinhardt, Wisconsin Regional Primate Research Center, University of Wisconsin, Madison, Wisconsin 53715, U .S.A. The crab-eating macaque (Macaca fascicularis), also known as the long-tailed macaque and referred to as the cynomolgus monkey in laboratories,[1] is a cercopithecine primate native to Southeast Asia. Immigrant males sometimes kill infants not their own in order to shorten interbirth intervals. More difference in relatedness occurs when comparing high-ranking lineages to lower ranking lineages, with higher-ranking individuals being more closely related to one another.

The M. f. umbrosa subspecies is likely of important biological significance and has been recommended as a candidate for protection in the Nicobar Islands, where its small, native population has been seriously fragmented,[48] and is listed as vulnerable on the IUCN Red List. Acta Endocrinologica 93, pp. Brasserie les monts d’auvergne, 63240 le mont dore. 7, 12, 36, 37, 44 Many factors affect the stability of and levels of aggression in primate groups, including age and sex composition, population density, and kinship structure. Crab-eating macaques are occasionally used as a food source for some indigenous forest-dwelling peoples. [24], Postconflict anxiety has been reported in crab-eating macaques that have acted as the aggressor. [citation needed] Plasmodium knowlesi, which causes malaria in M. fascicularis, can also infect humans. Macaca comes from the Portuguese word macaco, which was derived from makaku, a Fiot (West African language) word (kaku means monkey in Fiot). Sir Thomas Raffles, who gave the animal its scientific name in 1821, did not specify what he meant by the use of this word. American Journal of Primatology 20, pp. 10-15.

The genome of the crab-eating macaque has been sequenced. Academic Press, New York. The crab-eating macaque (Macaca fascicularis), also known as the long-tailed macaque and referred to as the cynomolgus monkey in laboratories, is a cercopithecine primate native to Southeast Asia. Consolation was not seen in any study performed. Animal Technology 42, pp. [30], The crab-eating macaque exhibits particularly low tolerance for swallowing seeds. These monkeys are very aggressive and dangerous. The rhesus' bad reputation is based on a belief with little verifiable evidence. Here they play together, forming crucial bonds that may help them when they leave their natal group. [26], A study was conducted in which food was given to 11 females.

When humans feed long-tailed macaques, both contact and non-contact aggression increases within and between groups of macaques at the same feeding site. 854-859. This suggests reconciliation rather than a property of the conflict is the cause of reduction in scratching behavior. Several years of experience with pair housing of previously singly-caged adult rhesus macaques and venipuncture in the home cage of cooperative, non-resisting animals lead the author to conclude that rhesus macaques are not as aggressive as commonly believed. ), then refusing to return their stolen goods until given food in return. [39] In Mauritius, it is a threat for the endemic and endangered Roussea simplex, as it destroys its flowers. Noyes Publication, Park Ridge. Line, S.W., Morgan, K.N., Roberts, J.A., and Markowitz, H. (1980): Preliminary comments on resocialization of aged rhesus macaques. 9-12. Comment représenter graphiquement une fonction. Though these results seem counterintuitive, the anxiety of the aggressor appears to have a basis in the risks of ruining cooperative relationships with the opponent. It is, therefore, not possible to assess if this is a newly emerging health threat, or if just newly discovered due to improved malarial detection techniques. The author hypothesized that previously singly-caged adult rhesus macaques should get along with each other in pairs, if both partners were familiar with each other and had a dominance-subordination relationship established prior to pair formation. The native range of this species includes most of mainland Southeast Asia, from extreme southeastern Bangladesh south through Malaysia, and the Maritime Southeast Asia islands of Sumatra, Java, and Borneo, offshore islands, the islands of the Philippines, and the Nicobar Islands in the Bay of Bengal. [11] It sometimes preys on vertebrates including bird chicks, nesting female birds, lizards, frogs, and fish, invertebrates, and bird eggs. Usually, less dominant individuals lose to a higher-ranking individual when conflict arises. [10], In addition to the matrilineal dominance hierarchy, male dominance rankings also exist. [19], Crab-eating macaques extensively overlap with humans across their range in Southeast Asia. The crab-eating macaque has several common names. They are supposedly not only belligerent toward humans and dangerous to handle, but also vicious toward other conspecifics and hence difficult to introduce to members of their own kind (Wickings and Nieschlag, 1980; Kessler et al., 1985; Line, 1987; Line et al., 1990; Reinhardt, 1991a). [1] A 2008 review of their populations suggests a need for better monitoring of populations due to increased wild trade and rising levels of human-macaque conflict, which are reducing overall population levels despite the species being widely distributed. There is a wide-spread belief that adult rhesus macaques are particularly aggressive animals (Vandenbergh, 1966; Southwick, 1967; Lindburg, 1971; Fairbanks et al., 1978; Teas et al., 1982; Thierry, 1985). [48] One concern for conservation is, in areas where M. fascicularis is not native, their populations need to be monitored and managed to reduce their impact on native flora and fauna.[48]. (1967): An experimental study of intragroup agonistic behavior in rhesus monkeys (Macaca mulatta). Bonadio, C. 2000. We took weekly 30-min behavioral observations on each group for one year to assess the patterns of hair pulling and grooming, which monkeys were receiving and initiating these behaviors, as well as aggression and other behaviors indicating dominance. The under parts are light grey with a dark grey/brown tail. I am grateful to my wife Annie for providing constructive critical comments on my manuscript. This project was supported by NIH grant RR-00167 to the Wisconsin Regional Primate Research Center. Sir Thomas Raffles, who gave the animal its scientific name in 1821, did not specify what he meant by the use of this word. (1985): Patterns of agonistic interactions in three species of macaque (Macaca mulatta, M. fascicularis, M. tonkeana). Staring at a caged rhesus monkey, for example, is unskillful; the gesture acts as a threat, and the 'cornered' animal has little choice but to react in a defensively aggressive way. Staff confirmed that aggressive behaviour had significantly lessened without tourists, as dominant monkeys no longer need to outcompete weaker monkeys for bananas. Some of these areas are associated with religious sites and local customs, such as the temples of Bali in Indonesia, Thailand, and Cambodia, while other areas are characterized by conflict as a result of habitat loss and competition over food and space.

In Mauritius, they are captured and sold to the pharmaceutical industry, and in Angaur and Palau, they are sold as pets. The IUCN Red List categorizes the species as Vulnerable, and CITES lists them as Appendix II ("not necessarily threatened with extinction", in which trade must be controlled to avoid use incompatible with their survival). Journal of Medical Primatology 16, pp. A few cases have been documented in humans, but for how long humans have been getting infections of this malarial strain is unknown. Aggression in rhesus macaques (Macaca mulatta), which comprise the majority of NHP used in biomedical research, has long been studied and generally focused on group dynamics. In Primate Behavior Vol. It should also be avoided for scientific reasons, since distress is likely to affect the subject's physiology and emotional state.

(1971): The rhesus monkey in North India: an ecological and behavioral study. Humans are also at risk when feeding long-tailed macaques because the possibility of disease transmission is increased when the two species come into contact. Reinhardt, V., Cowley, D., Eisele, S., and Scheffler, J. After having studied the behavior of several animal species for many years, the author has come to the conviction that captive animals are not particularly aggressive; management-related circumstances, however, can make them aggressive. [15] The tail is longer than the body, typically 40–65 cm (16–26 in), which is used for balance when they jump distances up to 5 m (16 ft). 1-3.

Thanks are also due to Mrs. Jackie Kinney for proof-reading the text. R. Holloway), pp. Familiar group members relate to each other in accordance with dominance-subordination relationships which serve as basic social structures essential for harmonious group life (Kaufman, 1967; Vandenbergh,1967). Reinhardt, V. (1991a): Group formation of previously single-caged adult rhesus macaques for the purpose of environmental enrichment. Emei, religious pilgrims and some tourists occasionally bring food provisions for the local macaques ( Macaca thibetana ), who often react with aggression while attempting to obtain food from humans. Piloerection 8 is a reflex arousal response in which the macaque’s hair stands up, making it look bigger, triggered by negative situations of extreme fear or anger.

[35][36], In Thailand and Myanmar, crab-eating macaques use stone tools to open nuts, oysters and other bivalves, and various types of sea snails (nerites, muricids, trochids, etc.) Their skin is black on their feet and ears, whereas the skin on the muzzle is a light grayish pink color. Thus, group relatedness on average appears to be lower than compared to matrilines. [40], Where it is not a native species, particularly on island ecosystems whose species often evolved in isolation from large predators, it is a documented threat to many native species. Animal Welfare Institute, 900 Pennsylvania Avenue, SE, Washington, DC 20003. It is often referred to as the long-tailed macaque due to its tail, which is often longer than its body.

[1] Its IUCN status was changed from Least Concern in 2020 as a result of declining population resulting from hunting and troublesome interactions with humans, despite its wide range and ability to adapt to different habitats. This, however, does not prove that the animals are particularly aggressive by nature. [15] The name crab-eating macaque refers to its being often seen foraging beaches for crabs. Aggressive contact is a concern in many locations, particularly among populations of rhesus and longtail macaques that co‐inhabit urbanized cities and towns with humans. [25], In a study, a group of crab-eating macaques was given ownership of a food object. along the Andaman sea coast and offshore islands. It was also repeatedly observed that not only adult females but also adult males temporarily carried and cradled infants to whom they were not related (Illustration 2).

The myth of the aggressive monkey probably is based on often not taking into account basic ethological principles when managing rhesus macaques in the research laboratory setting. In both captive and wild studies, the monkeys demonstrated reconciliation, or an affiliative interaction between former opponents, and redirection, or acting aggressively towards a third individual. The species' reputation for being conspicuously aggressive is evidently no reason for not transferring singly-caged individuals to a species-appropriate social environment, and to handle research subjects in gentle ways.
