Environmental enrichment of brown capuchins (Cebus apella): Behavioral and plasma and fecal cortisol measures of effectiveness

Plasma cortisol was significantly predicted by the proportions of both normal and abnormal behaviors; as the proportion of normal behavior increased, the plasma cortisol measures decreased. ... In light of our experimental findings that a variety of EE [environmental enrichment]...

Interactions among environmental enrichment, viewing crowds, and zoo chimpanzees (Pan troglodytes)

Responses to enrichment were influenced by the larger contextual surround of viewing crowed. Across the study's four conditions, larger crowds were generally significantly associated with decreased frequencies of foraging, object-using, grooming and playing.Abstract of this work has been published in:...

Terrestrial predator alarm vocalizations are a valid monitor of stress in captive brown capuchins (Cebus apella)

We have most commonly, but certainly not always, documented TPAs being produced in association with the entrance into or presence of humans in colony rooms. Most predictably those humans are research technicians associated with manipulative research projects involving the capuchins....

Integration of a female Francois langur (Presbytis francoisi francoisi) into an existing captive group

This study documents the successful integration of an adult female Francois langur into an existing group of 2 adult females and their 3 offspring and 1 adult male. Introductions of the new female to the other three adults were conducted...

Effect of tryptophan treatment on self-biting andcentral nervous system serotonin metabolism in rhesus monkeys (Macaca mulatta)

Two studies were conducted to examine the effects of oral L-tryptophan (TRP) supplementation as a treatment for self-injurious behavior (SIB) and to investigate behavior and central serotonin turnover of male rhesus monkeys. In Study One, TRP was administered to seven...
