Delgado, R., Fisherback, K., Szcodronski, J. et al. 2011. What's that smell? Sensory enrichment for g
An olfactory enrichment technique is described.
Honess, P., Fernadez, L. 2011. Environmental enrichment for captive and wild-born macaques. Enrichment Record 9, 16-18.
Although the use of wild-born primates in research is banned in some countries, in others it is commonplace. It has been demonstrated that not only do wild-born primates react more strongly to some stressors than...
Huber, H. F., Lewis, K. P. 2011. An assessment of gum-based environmental enrichment for captive gummivorous primates. Zoo Biology 30(1), 71-78.
In the wild, many primates consume gums exuded from trees, and many species are gum specialists. In spite of this, few data exist concerning gum feeding in captivity. Using a web-based survey of 46 zoos...
Malone, M. A., Leighty, K. A., Kuhar, C. W. et al. 2011. Behavioral response of silverback gorillas (Gorilla gorilla gorilla) to videos. Journal of Applied Animal Welfare Science 14(2), 96-108.
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...
Martin, A. L., Bloomsmith, M. A., Perlman, J. E. 2011. An assessment program to monitor behavior and evaluate
At the Yerkes National Primate Center we have developed a system for behavioral assessment that includes these elements: frequent observation of behavior for all primates with a check sheet-type record; a quantitative system for recording...
Owen, Y., Amory, J. R. 2011. A case study employing operant conditioning to reduce stress of capture for red-bellied tamarins (Saguinus labiatus). Journal of Applied Animal Welfare Science 14(2), 124-137.
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...
Rambo, M. 2011. Nonhuman primate positive reinforcement training: Flexible resource approach. American Association for Laboratory Animal Science [AALAS] Meeting Official Program, 777 (Abstract #P149).
In a review of current literature on positive reinforcement training, the majority of sources suggest that in order to produce results worthy of the time investment, training sessions must be held 2 to 3 times...
Robins, J. G., Waitt, C. D. 2011. Improving the welfare of captive macaques (Macaca sp.) through the use of water as enrichment. Journal of Applied Animal Welfare Science 14(1), 75-84.
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...
Rogge, J. R., Sherenco, K. D., Malling, R. et al. 2011. Establishing a positive reinforcement training program in neotropical
To enhance the psychological well-being of non-human primates, many biomedical facilities use positivereinforcement training (PRT) techniques to encourage voluntary participation in husbandry and clinical procedures.PRT increases the animal?s control over its environment and desensitizes the...
Ross, S. R., Calcutt, S., Schapiro, S. J. et al. 2011. Space use selectivity by chimpanzees and gorillas in an indoo
We used four years of detailed data on where 23 great apes (chimpanzees and gorillas) positioned themselves within a modern, indoor/outdoor zoo enclosure to determine not only how the apes utilized their space but also...
