Feeding bowl height preference in captive common marmosets (Callithrix jacchus jacchus)

Anticipation of conflict by chimpanzees

Captive chimpanzees appear to anticipate the occurrence of conflict during feeding by grooming and being in proximity at increased rates during the hours prior to feeding. The effect is more marked when food is clumped than when it is dispersed.

A method for using a pole housing apparatus to establish compatible pairs among squirrel monkeys

Pair formation protocol in a pole-and-collar housing system is described. Pair housing the animals has not interfered with research. During nine treatments with an identical test compound, singly housed animals lost significantly more weight on average than did pair housed...

Factors affecting the expression of self-injurious behavior in rhesus monkeys (Macaca mulatta)

Approximately 10% of laboratory housed rhesus monkeys spontaneously develop self-injurious behavior (SIB) such as biting their own bodies with sufficient force to produce tissue damage. ... Monkeys with SIB tended to spend a somewhat greater proportion of their lives in...

Training to reliably obtain blood and urine samples from a diabetic chimpanzee (Pan troglodytes)

Training techniques are described to gain the cooperation of a 3-year old female chimpanzee in obtaining blood and urine samples. The first blood draw occurred during the 18th training session, with a total of 275 minutes invested prior to that....

The influence of zoo visitors on the behaviour of captive chimpanzees (Pan troglodytes)

Zoo visitors who showed conspicuous behavior in front of the enclosure were a source of stressful excitement (decrease in play behavior, increase in displacement and agonistic behaviors).

Captive housing in macaques: Implications for immunoregulation

Considerable conflict and competition for access to the water spout was noted in pigtail macaques, whereas bonnet macaques queued up according to dominance status, waiting for their turn for access to the water. The preceding observations would imply that any...
