Videotapes: Environmental enrichment for singly housed chimpanzees

Subjects watched the videotapes an average of 75% of 20-minute test sessions. The results bring into discussion the value of enrichment that is used by [group-housed] nonhuman primates, but that does not improve behavioral measures of well-being.

The effects of separation from and subsequent reintroduction to an established group on a primiparous female lowland gorilla

Isolating a gorilla mother from her cagemates at the time of parturition can lead to abusive behavior directed towards the infant .... Social isolation is detrimental to the well-being of both mother and infant, and should be avoided as a...

Rigid plastic balls as enrichment devices for captive chimpanzees

The mean percentage of ball-use time for all subjects during the study [first ten hours after initial presentation] was 7.1%. There was no sex difference in ball use. Age and housing effects were obtained, with younger animals and those housed...

A social tethering system for non-human primates used in laboratory research

A custom-designed social-tether cage system is described. During the four years that the tether-social-group cages have been operational, we have never had a baboon in adjacent cage or even in the same cage bite the hand or fingers of another...

Conspecific introduction, socialization, and attempts to breed a solitary-raised, silverback male gorilla

Even though the silverback Colossus had not had an opportunity to interact with any other gorilla since infancy, his introduction to the adult female conspecific Muke was very successful. The careful pair formation procedure is described.

Effects of the addition of browse on the feeding behaviour (time budget and coprophagy) in captive bonobos

The addition of browse increased foraging time from 3 to 17% and resulted in a drastic decline in coprophagia.

Preliminary evaluation of Prima-Hedron play structures for non-human primates

Description of commercial roto-molded polyethylene structures serving as swing toys. The Prima-Hedrons' greatest virtues are that they can be assembled in so many ways that novelty is not restricted, and they can therefore maintain the interest of the monkeys using...
