Postconflict behavior in captive western lowland gorillas (Gorilla gorilla gorilla)

Postconflict (PC) behaviors, including reconciliation and consolation, have been observed in many primate and several nonprimate species. Using the PC-matched control (MC) method, PC behavior was examined in two groups (n=13) of captive western lowland gorillas, a species for which...

Artificial colour treatment mediates aggression among unfamiliar vervet monkeys (Cercopithecus aethiops): a model for introducing primates with colourful sexual skin

Painting the scrotum dark led to more aggression when these males were paired with dark coloured males and less aggression when these males were paired with pale coloured males. These findings suggest a practical and inexpensive means of reducing the...

Across both conditions, monkeys showed a strong preference for the upper-row cage indicating that elevation was more important than illumination in guiding location preference. Although monkeys did increase the amount of time that they spent in the lower row during...

Early predictors of self-biting in socially-housed rhesus macaques (Macaca mulatta)

Our findings suggest that the surrogate rearing condition in combination with lower levels of social contact during play may be risk factors for the later development of self-biting behavior.

Positive reinforcement training affects hematologic and serum chemistry values in captive chimpanzees (Pan troglodytes)

Positive reinforcement training (PRT) techniques have received considerable attention for their stress reduction potential in the behavioral management of captive nonhuman primates. However, few published empirical studies have provided physiological data to support this position. To address this issue, PRT...
