Warning: Rope in environmental enrichment

I have more than once recommended to people involved in environmental enrichment for macaques that sisal rope hanging outside of a cage made an excellent low-cost enrichment item for singly-housed macaques; they enjoy grooming, chewing, and pulling on it. However,...

Self-injurious behavior is decreased by cyproterone acetate in adult male rhesus (Macaca mulatta)

Self-injurious behavior (SIB) presents a serious problem in laboratory macaques that cannot be socially housed forscientific reasons and among institutionalized children and adults where it is often associated with different forms ofbrain dysfunction. We have experienced limited success in reducing...

Social housing and pregnancy outcome in captive pigtailed macaques

A greater number of moves decreased the probability of a viable birth and increased gestation length and the need for clinical treatment of the dam, while increased group size decreased gestation length. Increased moves and group size may increase stress...

Collecting blood of macaques: An often overlooked variable in biomedical research

The findings of this survey suggest that many investigators do not recognize that the traditional manner of collecting blood can introduce uncontrolled stress variables into research findings, leading to increased data variability and therefore increasing the number of experimental animals...

Affiliative behaviors of group housed rhesus macaques are altered by positive reinforcement training

Positive reinforcement training may be an effective tool for manipulating affiliative behaviors in rhesus macaques. Such manipulations may have important applications.

Techniques for collecting saliva from awake, unrestrained, adult monkeys for cortisol assay

Our laboratory has developed two methods [not outlined in this abstract] for collecting saliva [e.g., for cortisol determination] from adult rhesus monkeys: a 'screen' method, which involves licking screen-covered gauze, and a 'pole' method, which involves sucking and chewing on...

Trait-like immunological and hematological measures in female rhesus across varied environmental conditions

The immune measures were depressed at capture (excepting B cells), and during 7 months of single caging failed to return to normal levels associated with social housing [group of 5 females]. We thus conclude that single housing can produce significant,...

Assessing the value of television as environmental enrichment for individually housed rhesus monkeys: A behavioral economic approach

The goal of this study was to evaluate television as a source of environmental enrichment for individually housed rhesus monkeys (Macaca mulatta) by using the concepts of behavioral economics. Phase I entailed the use of operant conditioning to assess the...

The Sacred Monkeys of Bali

Excellent overview of species-typical behavior of wild long-tailed macaques. The study tropp spent more than 97 percent of their time in the trees. ... It is very doubtful, however, that terrestriality ever exceeded 10 percent of the day.
