    Contributor(s):: Hicks, T. C., Fouts, R. S., Fouts, D. H.

    Currently, the timber company Industrie Forestiere du Batalimo is selectively logging the Ngotto Forest in the Central African Republic. The forest is home to a population of chimpanzees (Pan troglodytes troglodytes) and gorillas (Gorilla gorilla gorilla) and provides the Bofi-speaking people of...

  3. Behavioral responses of silverback gorillas ( Gorilla gorilla gorilla ) to videos

    Contributor(s):: Maloney, M. A., Leighty, K. A., Kuhar, C. W., Bettinger, T. L.

    This study examined the impact of video presentations on the behavior of 4 silverback, western lowland gorillas (Gorilla gorilla gorilla). On each of 5 occasions, gorillas viewed 6 types of videos (blue screen, humans, an all-male or mixed-sex group engaged in low activity, and an all-male or...

  4. Combination therapy reduces self-injurious behavior in a chimpanzee ( Pan troglodytes troglodytes ): a case report

    Contributor(s):: Bourgeois, S. R., Vazquez, M., Brasky, K.

    Self-injurious behavior (SIB) remains a severe and intractable abnormal behavior for nonhuman primates in diverse settings and is a significant concern for veterinarians and behavioral scientists. To date, no single pharmacological, behavioral, social, or environmental intervention method has...

  5. Effect of enclosure size and complexity on the behaviors of captive chimpanzees ( Pan troglodytes )

    Contributor(s):: Jensvold, M. L. A., Sanz, C. M., Fouts, R. S., Fouts, D. H.

    Reports describing the implementation of innovative facility designs are important to both the primate caregiving community and policymakers reviewing current U.S. Department of Agriculture regulations. This study documents the changes in behaviour of 5 adult chimpanzees that coincided with...

  6. Empty nest: a case study of maternal response to separation from a juvenile offspring in a captive sumatran orangutan ( Pongo pygmaeus abelii )

    Contributor(s):: Tarou, L. R., Bashaw, M. J., Maple, T. L.

    Improving the welfare of captive nonhuman primates requires evaluating the stressors created by the captive environment and reducing their negative effects. Social separation, although sometimes necessary for managing the genetic diversity of captive populations of animals, causes both...

  7. Primate behavior studies: essential to primate welfare. Proceedings of the special Animal Behavior Society session, 2006

    Contributor(s):: Koch, V. W.

    This special issue contains 8 papers and 3 commentaries on the association between understanding nonhuman primate behaviour and providing for nonhuman primate welfare. The topics of the papers include: welfare of apes in captive environments; social housing for nonhuman primates in the research...

  8. Systematic investigation of the stability of food preferences in captive orangutans: implications for positive reinforcement training

    Contributor(s):: Clay, A. W., Bloomsmith, M. A., Marr, M. J., Maple, T. L.

    Using preference-assessment tests with humans in conjunction with behavioral modification sessions has been a regular component of almost all operant conditioning programs with mentally challenged humans. This has been very effective in improving the efficiency of behavioral training in these...

  9. The poor contribution of chimpanzee experiments to biomedical progress

    Contributor(s):: Knight, A.

    Biomedical research on captive chimpanzees incurs substantial nonhuman animal welfare, ethical, and financial costs that advocates claim result in substantial advancements in biomedical knowledge. However, demonstrating minimal contribution toward the advancement of biomedical knowledge...

  10. The role of behavioral research in the conservation of chimpanzees and gorillas

    Contributor(s):: Lonsdorf, E. V.

    Chimpanzees and gorillas are among man's closest living relatives, sharing most of the human genetic code and having many similarities to humans in anatomy, physiology, and behavior. Like humans, these apes make and use tools and have strong family bonds. Chimpanzees even show population-specific...

  11. Welfare of apes in captive environments: comments on, and by, a specific group of apes

    Contributor(s):: Savage-Rumbaugh, S., Wamba, K., Wamba, P., Wamba, N.

    Accurately determining the proper captive environment for apes requires adequately assessing the psychological similarities between apes and humans. Scientists currently believe apes lack mental complexity (Millikan, 2006), raising questions concerning the evolution of human culture from ape-like...

  12. A survey of the attitudes of stakeholders in the zoo industry towards the husbandry requirements of captive Great Apes

    Contributor(s):: Fernie, A. C., Tribe, A., Murray, P. J., Lisle, A., Phillips, C. J. C.

  13. Chimpanzee ( Pan troglodytes ) responses to caregiver use of chimpanzee behaviors

    Contributor(s):: Jensvold, M. L. A.

    The relationships between captive primates and their caregivers are critical ones and can affect animal welfare. Friendly relationships can improve quality of life; adversely, agonistic relationships can decrease quality of life. Caregivers in and of themselves should not be stressful to their...

  14. A note on enrichment for spontaneous tool use by chimpanzees ( Pan troglodytes )

    Contributor(s):: Morimura, N.

    In the wild, decisions as to "when", "where", and "how" an animal acts are made based on the individual's own choice; in contrast, the behaviour of wild animals in captivity may be under human control. To improve the physical and psychological well-being of captive animals, we should ensure that...

  15. Space use as an indicator of enclosure appropriateness: a novel measure of captive animal welfare

    Contributor(s):: Ross, S. R., Schapiro, S. J., Hau, J., Lukas, K. E.

    Empirical measures of animal behavior and space use within the captive environment can provide critical information about animals' requirements, preferences and internal states. The trend toward naturalistic environments has shown promise in terms of behavioral benefits for animals such as great...

  16. Tool use task as environmental enrichment for captive chimpanzees

    Contributor(s):: Celli, M. L., Tomonaga, M., Udono, T., Teramoto, M., Nagano, K.

    Wild chimpanzees spend 50-80% of their time foraging, using tools and other forms of manipulation, while captive chimpanzees cannot. In this study, a device - honey in a bottle to be "fished" with artificial materials - that elicits tool use was presented to six captive chimpanzees housed in...

  17. A note on the effect of auditory stimulation on the behaviour and welfare of zoo-housed gorillas

    Contributor(s):: Wells, D. L., Coleman, D., Challis, M. G.

    Auditory stimulation has long been employed as a form of therapy for humans and animals housed in institutions. Its effect on one of our closest-living relatives, the gorilla, however, is largely unknown. This study explored the effect of auditory stimulation on the behaviour and welfare of six...

  18. A note on the effect of olfactory stimulation on the behaviour and welfare of zoo-housed gorillas

    Contributor(s):: Wells, D. L., Hepper, P. G., Coleman, D., Challis, M. G.

    Olfactory stimulation has been shown to influence the behaviour of a wide variety of species and is now considered a useful form of environmental enrichment for many captive animals. To date, the effect of odour introduction on the behaviour of primates has been subject to little attention. This...

  19. A note on the influence of visitors on the behaviour and welfare of zoo-housed gorillas

    Contributor(s):: Wells, D. L.

    Visitors to zoos can be a source of potential stress to some captive-housed primates. To date, the effect of the human audience on the welfare of captive gorillas has been overlooked. This study thus examined the behaviour of six zoo-housed gorillas during periods of both high and low visitor...

  20. Use of space in a non-naturalistic environment by chimpanzees ( Pan troglodytes ) and lowland gorillas ( Gorilla gorilla gorilla )

    Contributor(s):: Ross, S. R., Lukas, K. E.

    Chimpanzees and gorillas are the two most common species of great ape in captive facilities in North America. This study examined patterns of space use by 14 gorillas and six chimpanzees housed in similar non-naturalistic environments at Lincoln Park Zoo in Chicago, IL. The location of each...
