The International Zoo Yearbook is an indispensable publication for everyone concerned with the care, conservation, biology and behaviour of wild animals. The papers and detailed reference lists represent the most up-to-date results of observations and research conducted in zoos and laboratories around the world and are the source of much data unobtainable elsewhere. Its coverage of the world's zoos, unequalled by any other medium, enables zoo people, zoologists, conservationists, veterinarians and anyone interested in wild animals to keep abreast of developments and studies in the zoo field, and equips them with an invaluable tool of permanent reference.
Section 1—the papers of the Second World Conference on Breeding Endangered Species in Captivity. The 23 papers cover the highly successful conference, held in London in July 1976. As a follow on from the first conference at Jersey, at which the technical possibilities of breeding many rare species were illustrated, these contributions concentrate on the principles underlying captive breeding programmes and the practical problems of conservation and reintroduction into the wild. The economic, ecological, genetic and behavioural aspects are considered and questions of whether and when to reintroduce are discussed. This section, introduced by Professor Ernst Lang, includes contributions from international experts and concludes with a thought-provoking – and sometimes controversial statement – from Lord Zuckerman, questioning man's priorities in wildlife conservation.
Section 2. New developments in the zoo world, is divided into the complementary and overlapping fields of breeding, husbandry, sex determination, hand-rearing, building and exhibition techniques, conservation and education. Continuing the theme of Section 1, there are 50 papers with a strong emphasis on breeding management of a wide range of species, including Bog turtles, Bateleur eagle, Brush-tailed bettong, Geoffroy's cat and shore and marine birds. The often vital question of sexing monomorphic species is covered in a short sub-section.
Section 3, the 120-page reference section, lists the species of vertebrates bred in captivity during 1975, where each was bred and which were the offspring of captive-born parents; the latest census of rare animals in captivity; and a report on the status of the various rare animal studbooks. The section concludes with a subject index and an author index to Volumes 1-17.
