    This study tested 3 food enrichment items mentioned in a laboratory primate newsletter with 6 adult Eulemur macaco and 3 adult Lemur catta to examine whether the items would affect the behavior of the lemurs. The results suggest that Food Enrichment Item 3 (a wire box filled with whole grapes,...

  7. Toward a science of welfare for animals in the zoo

    Contributor(s):: Maple, T. L.

    Although the accredited institutions of the Association of Zoos and Aquariums have all committed to enhancing the welfare of nonhuman animals, acceptable standards and best practices are still under debate. Currently, experts from zoos and the field hold widely divergent opinions about exhibition...

  8. Thinking outside our cages

    Contributor(s):: Patterson-Kane, E.

    Researchers seem to be stuck reiterating the now-familiar argument that barren boxes are bad for welfare and that rodents are due ethical consideration. But the prerequisites for real progress are new kinds of arguments, new types of data, and removal of very real practical and cultural obstacles...

  9. Improving the welfare of captive macaques ( Macaca sp.) through the use of water as enrichment

    Contributor(s):: Robins, J. G., Waitt, C. D.

    This review evaluates the use of water as a tool for enriching the environments of macaques (Macaca sp.) in captivity. Many macaque species are known to swim and forage in water in the wild, and in-situ reports suggest that access to water promotes activity and cultural behavior. Yet, there is a...

  10. Risk factors and remediation of self-injurious and self-abuse behavior in rhesus macaques

    Contributor(s):: Rommeck, I., Anderson, K., Heagerty, A., Cameron, A., McCowan, B.

    Considered signs of decreased welfare - abnormal behaviors such as self-injury and self-abuse among nonhuman primates housed in the laboratory - may put into question the validity and reliability of scientific research using these animals as models. Providing environmental enrichment decreases...

  11. A tail of two monkeys: social housing for nonhuman primates in the research laboratory setting

    Contributor(s):: Seelig, D.

    Despite great adaptability, most nonhuman primates require regular tactile contact with conspecifics for their psychological well being. By illustrating the inherent value of social contact and by providing clues to the best ways of satisfying this need, behavioral studies are useful in designing...

  12. Captive coyotes compared to their counterparts in the wild: does environmental enrichment help?

    Contributor(s):: Shivik, J. A., Palmer, G. L., Gese, E. M., Osthaus, B.

    This article attempts to determine the effects of environment (captive or wild) and a simple form of environmental enrichment on the behavior and physiology of a nonhuman animal. Specifically, analyses first compared behavioral budgets and stereotypic behavior of captive coyotes (Canis latrans)...

  13. Caregiver perceptions of what indoor cats do "for fun"

    Contributor(s):: Shyan-Norwalt, M. R.

    In a survey conducted to determine enrichment activities for indoor cats in the caregivers' homes, 304 indoor-cat caregivers answered structured interviews about their cats' use of windows and other "fun activities." The survey asked caregivers about durations of window use, what cats watched...

  14. Introducing a semi-naturalistic exhibit as structural enrichment for two brown bears ( Ursus arctos ). Does this ensure their captive well-being?

    Contributor(s):: Soriano, A. I., Ensenyat, C., Serrat, S., Mate, C.
