Optimal foraging theory predicts effects of environmental enrichment in a group of adult golden lion tamarins

Given the lack of habituation, the apparatus designed for this study could be used for regular captive golden tamarin environmental enrichment. However, because devices that increase foraging time also tend to increase rates of aggression, a prudent approach would be...

Heart rate responses to social interactions in free-moving rhesus macaques: (Macaca mulatta): A pilot study

Heart rate telemetry was explored as a means to access animal emotion during social interactions under naturalistic conditions. Heart rates of 2 middle-ranking adult females living in a large group of rhesus macaques (Macaca mulatta) were recorded along with their...

Affiliative interactions between singly-housed rhesus macaques in adjacent unmodified cages

Both males and females interacted with neighbors with a mean frequency of three times per hour; affiliative behavior made up approximately 60% of male-male interactions and 90% of female-female interactions. ... The extent of both male-male and female-female affiliation, despite...

A training programme for a male gorilla at Barcelona Zoo

Training program for voluntary ejaculation is described. In May 1998 we began the training program with Xebo. At the time of this writing (March 1999) Xebo understands ten different orders. ... So we hope that soon we will be able...

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....
