  5. World day for laboratory animals

    Contributor(s):: Marti Kheel

    The following speech was given in Berkeley on 1997’s World Day for Laboratory Animals. Activists had been concerned for two decades with the fate of Langur monkeys at U. C. Berkeley. As of the date of this speech, the monkeys had been offered a home in a sanctuary, but it was unclear whether the...

  7. Frequency of feeding enrichment and response of laboratory nonhuman primates to unfamiliar people

    Contributor(s):: Baker, K. C., Springer, D. A.

    Although environmental enhancement plans for nonhuman primates vary between facilities, feeding enrichment represents a component of most programs. As part of a facility's feeding enrichment program, offering hand-fed food items by trained staff provides an opportunity for positive human...

  9. Interactions between humans and capuchin monkeys ( Cebus libidinosus ) in the Parque Nacional de Brasilia, Brazil

    Contributor(s):: Sabbatini, G., Stammati, M., Tavares, M. C. H., Giuliani, M. V., Visalberghi, E.

    The Parque Nacional de Brasilia, in Brazil, is visited daily by hundreds of people, because of its relative proximity to the city of Brasilia and the presence of natural swimming pools, trials and picnic areas. Capuchin monkeys habitually feed on the food that visitors give them, take food from...

  10. The effects of predictable and unpredictable feeding schedules on the behavior and physiology of captive brown capuchins ( Cebus apella )

    Contributor(s):: Ulyan, M. J., Burrows, A. E., Buzzell, C. A., Raghanti, M. A., Marcinkiewicz, J. L., Phillips, K. A.

    Responses to different feeding schedules in group living capuchins (Cebus apella) were evaluated. Animals were fed on a predictable schedule for 6 weeks followed by 6 weeks on an unpredictable schedule (varied by early, on-time, or late feedings). Behaviour was sampled via scan sampling at 1 min...

  11. Visitor-associated variation in captive Diana monkey ( Cercopithecus diana diana ) behaviour

    Contributor(s):: Todd, P. A., Macdonald, C., Coleman, D.

    This research examines the relationship between visitor numbers and the behaviour of Diana monkeys (Cercopithecus diana diana). A family group of two adult and four juvenile captive Diana monkeys was studied intensively for 10 days at Edinburgh Zoo, UK. The six subjects were scan sampled every 5...

  12. A brief note on the effects of the removal of individuals on social behaviour in a captive group of campbell's monkeys ( Cercopithecus campbelli campbelli ): a case study

    Contributor(s):: Lemasson, A., Gautier, J. P., Hausberger, M.

    We investigated the social effects of the removal of two adult females, including the founder of a matriline, in a group of captive Campbell's monkeys (Cercopithecus campbelli campbelli). Their social behaviour was recorded 1 month before, 1 week after, and 7 months after the removal of the...

  13. A note on indoor and outdoor housing preferences of common marmosets ( Callithrix jacchus )

    Contributor(s):: Pines, M. K., Kaplan, G., Rogers, L. J.

    This study examined the preferences of six pairs of common marmosets (Callithrix jacchus) from the colony at the University of New England, Australia, between their home cage and either a large, enriched, indoor room or a smaller outdoor cage. When given free access to move between their home...

  14. Comparison of the behaviour of captive white-faced capuchin monkeys ( Cebus capucinus ) in the presence of four kinds of deep litter

    Contributor(s):: Ludes, E., Anderson, J. R.

    Captive white-faced capuchin monkeys (Cebus capucinus) were placed in a large indoor room without or with deep litter made of wood chips, dried ground maize cob, wood wool or garden peat. Feed was scattered on the bare floor or on the litter and the behaviour of the monkeys was observed. When...

  15. Use of horizontal and vertical climbing structures by captive common marmosets ( Callithrix jacchus )

    Contributor(s):: Pines, M. K., Kaplan, G., Rogers, L. J.

    This study examined the effects of the orientation of bars as an aspect of internal cage design on the behaviour of 12 common marmosets (Callithrix jacchus). Each marmoset was tested individually in four separate test-cage conditions: (V) vertical bars, (H) horizontal bars, (V/H) vertical and...

  16. The use of positive reinforcement training to reduce stereotypic behavior in rhesus macaques

    Contributor(s):: Coleman, K., Maier, A.

    Stereotypic behavior is a pervasive problem for captive monkeys and other animals. Once this behavior pattern has started, it can be difficult to alleviate. We tested whether or not using positive reinforcement training (PRT) can reduce this undesired behavior. Subjects for this study were 11...

  17. An example of a monkey assistance program: P.A.S.T. - the French project of simian help to quadriplegics: a response to Lannuzzi and Rowan's (1991) paper on ethical issues in animal-assisted therapy programs

    Contributor(s):: Deputte, B. L., Busnel, M.

    All animal-assisted therapy programs raise ethical issues. These ethical issues are even more important when non-domesticated animals are used to help humans with disabilities. In their 1991 review, Iannuzzi and Rowan mentioned programs which use capuchin monkeys to help quadriplegics. The lack...

  18. Influence of a capuchin monkey companion on the social life of a person with quadriplegia: an experimental study

    Contributor(s):: Hien, E., Deputte, B. L.

    As a consequence of a severe reduction in their autonomy, the social life of people with quadriplegia becomes highly routine. In addition, the social environment becomes very limited because people without disabilities may feel awkward around, or have an aversion to, people with quadriplegia. A...

  19. Tourist impact on Tibetan macaques

    Contributor(s):: Matheson, M. D., Sheeran, L. K., Li, JinHua, Wagner, R. S.

    Ecotourism is a growing sector of the tourism industry, but few studies to date have quantified its impacts on local people, tourists and wildlife. We present a preliminary study on threat and affiliative behaviors of two groups of free-ranging Tibetan macaques (Macaca thibetana) as a function of...

  20. Where have all the monkeys gone? The changing nature of the Monkey Temple at Bristol Zoo

    Contributor(s):: Shapland, A.

    Built in 1928, the domed structure once called the Monkey Temple still stands in Bristol Zoo, UK, the architecture preserved by planning regulations, but the enclosure remodelled and rebranded as the Smarty Plants exhibit. Its transformation is used as an archaeological case study to illustrate...
