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,...

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.

Effects of separation and novelty on distress vocalizations and cortisol in the common marmoset (Callithrix jacchus)

In socially-bonding species, separation from familiar attachment figures is widely known to stimulate a physiological and behavioral stress response. This study investigated the hormonal and vocal responses of adult common marmosets to separation from familiar group members and to 24...

Behavioral changes in captive chimpanzees

Overall, after the move to the larger [structurally enriched] facility, there was an increase in activity, a decrease in stereotypical behaviour, and an increase in threat behavior.
