Pairing previously singly caged rhesus monkeys does not interfere with common research protocols

Our experiences indicate that facilitated socialization of previously singly caged rhesus monkeys offers an inexpensive method of environmental enrichment that is practicable under common management situations and numerous research conditions.

Facilitated socialization of previously singly caged adult rhesus macaques (videotape with accompanying text)

Thirty scenes depict different adult rhesus monkeys [and one adult, male stump-tailed macaque], each paired with a compatible companion for up to two years. The following pair combinations and research situations are shown: adult male/male, adult female/female, adult male/juvenile male,...

Re-pairing caged rhesus monkeys

Our attempts to re-pair adult [female] caged rhesus monkeys [without prior familiarization] who have lost their companions have consistently been successful.

Evaluation of the long-term effectiveness of two environmental enrichment objects for singly caged rhesus macaques

Subjects were exposed to a PVC pipe and to a gnawing stick uninterruptedly for one year. The singly caged monkeys spent on average 28% of the total observation time [120 min] with the PVC pipes but only 3% with the...

Behavioral responses of unrelated adult male rhesus monkeys familiarized and paired for the purpose of environmental enrichment

Potential companions were first given the opportunity to establish clear-cut rank relationships during a 5-day period of noncontact familiarization. Only then were they paired in a different double cage. Rank relationships were confirmed within the first 6 minutes after pairing...

Auditory enrichment for Lar gibbons, Hylobates lar, at London Zoo

Playing duets to captive gibbons resulted in increased species-typical activity and vocalisation without evidence of habituation.

Alternatives to single caging of rhesus monkeys

Single-housed rhesus macaques were transferred to permanent pair-housing arrangements. The present investigation also demonstrates that pairing caged rhesus monkeys with compatible conspecifics does not interfere with a number of common research protocols [e.g., headcap implantation, experimental surgery, blood collection]. Our...

Introduction to a very helpful book. Nowhere in this book is it asserted that research with captive primates should not be done. Everywhere it is asserted that it should be done with care, respect, and humanity. A few would add,...

Compatible rhesus monkeys provide long-term stimulation for each other

The [12 pair-housed] rhesus monkeys in the present study distracted each other in species-typical ways on average 35% of the time, even though the companions had lived with each other continually for 2.5 years. Apparently, a compatible companion is a...

Effects of environmental impoverishment on the social behavior of marmosets (Callithrix jacchus)

Family groups of marmosets were moved from a greenhouse enclosure to caged environments of increasingly limited size and stimulation. Social behaviors such as approach, follow, play, and grooming declined substantially. ... Nonsocial behaviors such as scent marking and locomotion also...
