Psychological well-being and other projections of the human condition: Their meaning for research activities with non-human primates

The often cited paradox for researchers studying nonhuman primates is that we must consider them sufficiently similar to us so that our studies will be valid and significant; at the same time we must consider them sufficiently different that we...

The Detroit Zoo Chimpanzees Pan troglodytes: exhibit design, group composition and the process of group formation

All adults were introduced to each other first through mesh and then physically. ... Before all physical introductions, the Chimpanzees involved were fed double their normal morning rations and then fed a single ration ten minutes prior to the start...

A preliminary study of the effects of ecologically relevant sounds on the behaviour of captive lowland gorillas

Moderate levels of noise associated with captive animal housing, particularly intermittent noises, may be stressful for animal inhabitants. This is particularly noteworthy in that these effects did not disappear over time, countering those who might suggest that 'noise is okay,...

Small primate enrichment at the Calgary Zoo, part 3: patas and spider monkeys

Some feeding enrichment options are reported. Some animals leaped several feet to a fruit stuck on branches, even when fruit was freely available on the ground.

When trying to get your monkeys to behave, try perches

Higher perching elevations appear to be a very desirable feature in this environment for the expression of six of the twelve behaviors studied. Mid-level perches, on the other hand, were utilized more for only two of the behaviors: self play...

Facilitating the expression of species-specific behaviors

The attractiveness of high and mid-level perches for nine of the twelve behaviors studied is also apparent. Ground level was the location selected most often [by group-housed animals] for locomotion and foraging. Although the findings suggest that the indoor areas...

Psychological and hormonal aspects of hierarchy formation in groups of male squirrel monkeys

Five triads were established by releasing simultaneously three previously pair-housed males into large cages. Males of newly formed trios spent an average of 44% of their time huddling in affilative contact with male cagemates.
