  3. Reconsidering coprophagy as an indicator of negative welfare for captive chimpanzees

    Contributor(s):: Hopper, L. M., Freeman, H. D., Ross, S. R.

    For captive chimpanzees, 'abnormal' behaviours include behaviours observed only in captivity (i.e. species-atypical behaviours) and those that are performed at higher rates in captivity compared to in the wild. Both types are used as metrics for evaluating captive primates' welfare. However,...

  4. Hair plucking in captive bonobos ( Pan paniscus)

    Contributor(s):: Brand, C. M., Marchant, L. F.

    Both wild and captive studies of grooming in non-human primates emphasize the adaptive role of this behavior. Indeed, social grooming is frequently characterized as "social glue" in the life of primates. Grooming behavior is studied to reveal dominance, kin relations, and social networks. Many...

  5. A pilot study on the effects of a change in behavioural management on the behaviour of captive chimpanzees ( Pan troglodytes)

    Contributor(s):: Kranendonk, G., Schippers, E. P.

    The debate on the use of chimpanzees ( Pan troglodytes) in biomedical research has been ongoing for several years now. In 2012, the decision was made to retire a large number of laboratory chimpanzees in the United States of America. Relocation of these animals to sanctuaries, rescue centres, and...

  6. A case study of orangutan and siamang behavior within a mixed-species zoo exhibit

    Contributor(s):: Pearson, E. L., Davis, J. M., Litchfield, C. A.

    This empirical case study assessed the behavior and welfare of 2 orangutans (Pongo abelii) and 2 siamangs (Symphalangus syndactylus) within a mixed-species zoo exhibit. The study used instantaneous scan-sampling to record behavior, location, and interspecies proximity over 174 hr and...

  7. A case study of primiparous maternal and infant gorilla ( Gorilla gorilla gorilla ) behavior

    Contributor(s):: Crosby, J. Y., Lukas, K. E.

    A primiparous mother and her infant were subjects of a longitudinal behavioral study at Lincoln Park Zoo in Chicago, Illinois. From November 1998 to November 1999, we collected a total of 100 hr of focal nonhuman animal instantaneous point sampling and all occurrence data on the mother and her...

  8. A survey of chimpanzees ( Pan troglodytes troglodytes ) and gorillas ( Gorilla gorilla gorilla ) in the selectively logged Ngotto Forest, Central African Republic

    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...

  9. 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...

  10. 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...

  11. 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...

  12. 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...

  13. Positive reinforcement training as a technique to alter nonhuman primate behavior: quantitative assessments of effectiveness. (Training Nonhuman Primates Using Positive Reinforcement Techniques)

    Contributor(s):: Schapiro, S. J., Bloomsmith, M. A., Laule, G. E.

    Many suggest that operant conditioning techniques can be applied successfully to improve the behavioral management of nonhuman primates in research settings. However, relatively little empirical data exist to support this claim. This article is a review of several studies that discussed applied...

  14. 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...

  15. 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...

  16. The choice to access outdoor areas affects the behavior of great apes

    Contributor(s):: Kurtycz, L. M., Wagner, K. E., Ross, S. R.

    Outdoor access is often cited as a critical component of appropriate housing for great apes in captivity, and although studies have shown that offering primates choices can improve welfare, choice to access specific areas has been empirically neglected. Behavioral data were collected on...

  17. 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...

  18. 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...

  19. 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...

  20. Empathy and donation behavior toward happy and sad chimpanzees

    Contributor(s):: Telle, N. T., Pfister, H. R.

    Past research indicates a moderate but robust relationship between human empathy and empathy toward animals. Further, it has been shown that human empathy is associated with more positive attitudes toward animals. What has not been researched, however, is human- and animal-directed empathy in...
