Female tamarins (Saguinus – Callitrichidae) feed more successfully than males in unfamiliar foraging tasks

Access to grapes was restricted to a circular hole [in a perspex box secured to the wall of the cage] of 3.5 cm in diameter. ... Females became more responsive to the additional food. There was no evidence of overt...

Individual differences in macaques’ responses to stressors based on social and physiological factors: implications for primate welfare and research outcomes

Non-human primates exhibit distinct individual differences in their behavioural and physiological responses to experimental challenges and caretaking procedures. We have been investigating what factors can predict some of these individual differences, and have found that factors both intrinsic and extrinsic...

Effects of predictable versus unpredictable feeding schedules on chimpanzee behavior

These findings indicate that feeding on a more unpredictable schedule may lead to increased species-appropriate behavior [more activity, less abnormal behavior] in group-housed chimpanzees.

Dealing with specific behavioral problems using operant conditioning with bonobos (Pan paniscus)

Training technique is described. Although we still have days when animals refuse to shift, scream, or act out aggressively, for the most part these negative and highly disruptive behaviors have greatly diminished.

A study of environmental enrichment in groups of captive lion tamarins (Leontopithecus rosalia & Leontopithecus chrysmelas)

Woodwool turned out to be a very useful substrate for group-housed tamarins. An important effect of the woodwool substrate was increased hygiene. An insect dispenser is described which was rarely used by adults, who would sit underneath it and wait...

The effect of food distribution on captive Old World primates

When the food was placed in a single pile on the top of the cage the [group-housed] monkeys were still eating at the end of the 30 minute observation session.

Nonhuman primate wounding prevalence: A retrospective analysis

A survey of the occurrence of injuries in group-housed, pair-housed and individually housed macaques. Females acquired wounds and required wound management more frequently than males in group-housed macaques. Individually housed males engaged in self-biting behaviour more often than their female...

Effects of environmental enrichment on nonsocial and abnormal behavior of captive lowland gorillas (Gorilla gorilla gorilla)

The use of straw as bedding material appears to have a positive effect on both specific nonsocial [feeding/foraging] and abnormal behavior [coprophagy, regurgitation].
