Heart rate changes associated with tethering of cynomolgus monkeys

The results suggest that some amount of cardiovascular (and perhaps hormonal) disturbance may persist in tethered animals, even if several weeks are allowed for 'habituation'.

Mirror-image responses in pygmy marmosets (Cebuella pygmaea)

The pygmy marmosets displayed a rapid extinction of social threat responses to their own image and of novelty responses to mirrors, but continued to show mirror-specific responses such as following their own image, playing peek-a-boo, and looking at their image...

Reconciliation and redirected affection in rhesus monkeys

The question whether rhesus monkeys reconcile was empirically translated as: Do they seek non-agonistic contact with former adversaries? The study concerned a captive group of forty-one monkeys, Macaca mulatta. Participants in 350 aggressive incidents were followed both immediately after the...

Cage-size effect on locomotor, grooming and agonistic behaviors of the slow loris (Nycticebus coucang)

Results of the experiments in this study indicate that slow lorises kept in larger [furnished] cages will be more active than those housed in [furnished] cages approaching recommendations for size proposed by the U.S. National Research Council.
