A review of reproductive patterns in new world monkeys.

A review of the literature indicated that most of the information of reproductive patterns in New World monkeys has been gained from studies on the squirrel monkey. This species has been successfully bred in both indoor and outdoor colonies. Both sexes exhibit seasonal cyclicity that appears to be influenced by a number of environmental conditions. Reports indicated that most of the other New World species have been bred in captivity, most commonly in zoos. The scientific data on these species are sparse, usually obtained from small groups or individual animals.
