Environmental enrichment objects for the improvement of locomotion of caged rhesus macaques (Macaca mulatta)

Juveniles used the mobile objects [treadmill and rotating barrel] more than the adults. Due to the increase in locomotion, the amount of time spent in aggressive behavior significantly decreased.

Presence of a privacy divider increases proximity in pair-housed rhesus monkeys

We observed twenty-five pairs of rhesus macaques (Macaca mulatta) both with and without the presence of a privacy divider. Monkeys spent significantly more time in the same half of the pair-cage when the divider was in place. Subjects were fifty...

Pair-Housed Monkeys with Head Cap Implants

Our university tries to pair all rhesus macaques regardless of cranial implants. Normally the pairs are established before they have undergone surgery for head caps, but we have successfully paired primates after surgery as well. Over a period of ten...

Introducing macaques to novel housing systems mid-experiment: Proactive behavioral management

The primary concern was that the novelty of increased vertical space within the new housing system would cause the macaques to be less motivated to transition to the restrainer and/or perform experimental tasks mid-experiment. .. A cage conditioning plan was...

Beta-endorphin levels in longtailed and pigtailed macaques vary by abnormal behavior rating and sex

Frequent or severe abnormal behavior may be associated with the release of endorphins that positively reinforce the behavior with an opiate euphoria or analgesia. One line of research exploring this association involves the superhormone, proopiomelanocortin (POMC). The products of POMC...

Socially-mediated learning in groups of primates: models and methods

An ethological understanding of a behavioral phenomenon incorporates four levels of explanation: development, mechanism, function, and evolution. The phenomenon of socially-mediated learning has garnered a great deal of attention from ethologists, prominently including primatologists. Gregarious primates often exhibit specific behaviors...

Pair-housing and initial SIV infection in adult male rhesus macaques (Macaca mulatta)

Levels of contact affiliation almost doubled in all four subjects in the immediate post-inoculation period. Body temperature and contact affiliation remained elevated in the subsequent two-week period. Contact aggression was not recorded during the first month after inoculation. Preliminary data...
