This collection of essays is the first major work in more than a decade to discuss the critical issue of wildlife contraception and the first ever to take up contraception-both theory and practice-for wild animals in captivity. The authors, leading international experts on the subject, analyze the use of wildlife contraception for various animal populations, including nonhuman primates, ungulates, pinnipeds, cetaceans, and other mammals. The chapters examine and critique types of contraception, and their effects, and explore the best method for each situation. Using the most recent data and findings, this comprehensive collection addresses problems related to unrestricted population growth, the ethics of wildlife contraception, and regulatory issues for wildlife managers, animal rights organizations, zoos worldwide, and anyone interested in the humane control of animal populations.
