Shutt, K., MacLarnon, A., Heistermann, M. et al. 2007. Grooming in Barbary macaques: better to give than receive? Biology Lett

It is well established that grooming underpins sociality in group-living primates, and a number of studies have documented the stress-reducing effects of being groomed. In this study, we quantified grooming behaviour and physiological stress (assessed...

Csatádi, K., Leus, K., Pereboom, J. J. M. 2008. A brief note on the effects of novel enrichment on an unwanted behaviour of ca

Animals in captivity may show undesirable behaviour when they are not sufficiently challenged, making it essential for their well-being to provide daily enrichment to zoo animals. Primates need a regular replacement with novel enrichment objects...

Behavioral observations were conducted as an ongoing program of monitoring psychological well-being of chimpanzees involved in IACUC-approved preventive medicine studies. The chimpanzees were housed in a facility that provided a variety of enrichment objects, climbing...

Leland, S. P., West, A. M., Pippin, Z. L. et al. 2008. Effects of familiarity and novelty on rates of environmental enrichment

Manipulable objects are often provided to laboratory macaques as environmental enrichment, but exposure to objects is widely believed to result in rapid habituation. Consequently, much effort is made to ensure enrichment objects are novel. Here...
