A note on the effect of olfactory stimulation on the behaviour and welfare of zoo-housed gorillas

Overall, findings suggest that olfactory stimulation in the form of odour-impregnated cloths has little effect on the behaviour of captive gorillas. This raises questions over the value of olfactory stimulation as a useful method of environmental enrichment for this species.

Innovative social behavior in chimpanzees (Pan troglodytes)

We present evidence of agonistic buffering in captive chimpanzees, recorded from 1993 until 2005, mainly from ad libitum sampling in over 2000 hr of observation. A total of 33 agonistic buffering episodes were analyzed for context and effects of this...

Ground substrate affects activity budgets and hair loss in outdoor captive groups of rhesus macaques (Macaca mulatta)

This study investigated the influence of grass vs. gravel substrate on activity budgets and degree of hair loss in seven groups of captive rhesus macaques housed in outdoor enclosures at the California National Primate Research Center. Groups having grass substrate...
