Social interactions between captive adult male and infant lowland gorillas: Implications regarding kin selection and zoo management

The unrelated infant was the recipient of more than 40% of the agonistic behavior exhibited by the silverback, whereas no such encounters were recorded with the related dyad. ... Infants may be introduced into non-natal groups without being attacked or...

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...

Removing milk from captive gorilla diets: The impact on regurgitation and reingestion (R/R) and other behaviors

The current study provides evidence that removal of milk from the captive gorilla diet may [emphasis added] reduce undesirable behaviors such as R/R.

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...

Validating the efficacy of primate enrichment programs

Comparing the frequency of abnormal behaviors across time provides a means of assessing the success of specific enrichment activities such as manipulanda usage and pair- or group-housing, as well as assessing the overall effectiveness of the enrichment program.

Marmosets and Tamarins

General recommendations for the species-adequate housing of marmosets and tamarins. Single caging is unsatisfactory for these highly social animals as they soon lose condition, appear nervous, are often more susceptible to disease, and may even die. As mature individuals are...

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,...
