  1. Captive Audiences: Interactions Between Visitors and Bonobos at the San Diego Zoo

    Full-text: Available

    | Contributor(s):: Elena Miyoko Carver

    Primate exhibits in American zoological parks, especially those featuring the great apes, are among the most compelling, complex, and popular exhibits for visitors, and are a primary way the American public becomes familiar with our closest living relatives. In this study, I approach the...

  2. Dogs (Canis familiaris), but Not Chimpanzees (Pan troglodytes), Understand Imperative Pointing

    Full-text: Available

    | Contributor(s):: Katharina C. Kirchhofer, Felizitas Zimmermann, Juliane Kaminski, Michael Tomasello

    Chimpanzees routinely follow the gaze of humans to outside targets. However, in most studies using object choice they fail to use communicative gestures (e.g. pointing) to find hidden food. Chimpanzees' failure to do this may be due to several difficulties with this paradigm. They may, for...

  3. The impact of atypical early histories on pet or performer chimpanzees

    Full-text: Available

    | Contributor(s):: Hani D. Freeman, Stephen R. Ross

      It is widely accepted that an animal’s early history, including but not limited to its rearing history, can have a profound impact on later behavior. In the case of captive animals, many studies have used categorical measures such as mother reared or human reared that do not...

  4. 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,...

    | Contributor(s):: Prince, AM

  6. 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...

  18. 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...
