  1. World Day for Laboratory Animals

    Contributor(s):: Kheel, M.

  2. The Human Intruder Test: An Anxiety Assessment in Rhesus Macaques (Macaca Mulatta)

    Contributor(s):: Emily J. Peterson

    The human intruder test (HIT) is a noninvasive tool widely used for assessing anxiety in rhesus macaques (Macaca mulatta). This thesis explores the HIT procedure and applies it to a population of monkeys with a self-injurious behavioral pathology. Individual variation on this test can be used to...

  3. Evaluation of environmental and intrinsic factors that contribute to stereotypic behavior in captive rhesus macaques ( Macaca mulatta)

    Contributor(s):: Gottlieb, D. H., Maier, A., Coleman, K.

    Full body repetitive behaviors, known as motor stereotypic behaviors (MSBs), are one of the most commonly seen abnormal behaviors in captive non-human primates, and are frequently used as a behavioral measure of well-being. The main goal of this paper was to examine the role of environmental...

  4. Chinese visitors' experiences of nature and wild macaques: inspiration and personal growth for living in Hong Kong

    Contributor(s):: Lee, WingNaam, Davey, G.

    Country parks offer urban residents the opportunity to experience wildlife, engage in environmental education, and socially bond with family and friends, but little is known about these experiences in China. Twenty-five interviews were conducted in 2012 to investigate the meanings Hong Kong...

  5. The effect of a feeding schedule change and the provision of forage material on hair eating in a group of captive baboons ( Papio hamadryas sp.)

    Contributor(s):: Nevill, C. H., Lutz, C. K.

    Hair eating in nonhuman primates is thought to result from a frustrated appetitive drive produced by an inappropriate diet. To investigate whether hair eating could be reduced through changes in diet, a 2-part study was conducted with a group of baboons ( Papio hamadryas sp.). The 1st part...

  6. Effects of visual contact with zoo visitors on black-capped capuchin welfare

    Contributor(s):: Sherwen, S. L., Harvey, T. J., Magrath, M. J. L., Butler, K. L., Fanson, K. V., Hemsworth, P. H.

    Previous research has suggested that the presence of zoo visitors may be stressful for various primate species, and visual contact with visitors may be the sensory stimuli that mediate visitor effects. We studied a group of black-capped capuchins, Cebus apella, in a controlled experiment,...

  7. Refinement of welfare through development of a quantitative system for assessment of lifetime experience

    Contributor(s):: Wolfensohn, S., Sharpe, S., Hall, I., Lawrence, S., Kitchen, S., Dennis, M.

    This paper proposes a system that uses intrinsic study data to provide a clear visualisation of the stresses involved during the animal's life history that can be applied to all types of studies, even those not requiring invasive techniques. Thus, it provides an opportunity for researchers to...

  8. Can humans discriminate between dogs on the base of the acoustic parameters of barks?

    Contributor(s):: Molnar, C., Pongracz, P., Doka, A., Miklosi, A.

  9. Preference for human eyes in human infants

    Contributor(s):: Dupierrix, Eve, de Boisferon, Anne Hillairet, Méary, David, Lee, Kang, Quinn, Paul C., Di Giorgio, Elisa, Simion, Francesca, Tomonaga, Masaki, Pascalis, Olivier

  10. Road kill in Cameroon

    Contributor(s):: McRae, Michael

  11. Baboons of the Amboseli basin: demographic stability and change

    Contributor(s):: Samuels, A.

  12. Catch me if you can: monkey capture in Delhi

    Contributor(s):: Gandhi, Ajay

  13. Dramatic consequences of food handouts to Macaca thibetana at Mount Emei, China

    Contributor(s):: Zhao, Qi-Kun

  14. Geographic microsatellite variability in Central American howling monkeys

    Contributor(s):: Winkler, Linda A.

  15. Naturalcultural encounters in Bali: monkeys, temples, tourists, and ethnoprimatology

    Contributor(s):: Fuentes, Augustín

  16. Social behavior of black-handed spider monkeys (Ateles geoffroyi) reared as home pets

    Contributor(s):: Anaya-Huertas, C.

  17. Species-specific responses to tourist interactions by white-faced capuchins (Cebus imitator) and mantled howlers (Alouatta palliata) in a Costa Rican wildlife refuge

    Contributor(s):: McKinney, Tracie

  18. Left gaze bias in humans, rhesus monkeys and domestic dogs

    Contributor(s):: Kun Guo, Daniel Mills, Kerstin Meints, Charlotte Hall, Sophie Hall

    While viewing faces, human adults often demonstrate a natural gaze bias towards the left visual field, that is, the right side of the viewee’s face is often inspected first and for longer periods. Using a preferential looking paradigm, we demonstrate that this bias is neither uniquely human...

  19. Social housing of non-human primates in a research facility: socialisation across macaque species and sexes

    Contributor(s):: Rehrig, A., DiVincenti, L., Jr., Schery, L. A.

    Refinement of social housing practices is paramount to improving animal welfare in laboratory environments, especially with regard to non-human primates. Even though social housing of the same species should be considered the optimal paradigm, cynomolgus ( Macaca fascicularis) and rhesus macaques...

  20. A case study employing operant conditioning to reduce stress of capture for red-bellied tamarins ( Saguinus labiatus )

    Contributor(s):: Owen, Y., Amory, J. R.

    Traditional techniques used to capture New World monkeys, such as net capture, can induce high levels of acute stress detrimental to welfare. Alternatively, training nonhuman animals via operant conditioning to voluntarily participate in husbandry and/or veterinary practices is accepted as a...
