Housing and care of monkeys and apes in laboratories: adaptations allowing essential species-specific behaviour.

During the last two decades an increasing amount of attention has been paid to the housing and care of monkeys and apes in laboratories, as has been done with the housing and care of other categories of captive animals. The purpose of this review is to develop recommendations for adaptations of housing and care from our knowledge of the daily behavioural activity of monkeys and apes in natural conditions and in enriched laboratory conditions. This review deals mainly with adaptations of daily housing and care with respect to behaviour, and it is restricted to commonly-used species: Callitrichidae (Callitrix jacchus, Saguinus oedipus); Cebidae (Aotus trivirgatus, Saimiri sciureus, Cebus apella); Cercopithecidae (Macaca fascicularis, M. mulatta, M. nemestrina, M. arctoides, Chlorocebus aethiops, Papio hamadryas, P. cynocephalus); Pongidae (Pan troglodytes).
