A multi-disciplinary approach to endangered species conservation, organised taxonomically and by scientific discipline. Seven taxonomic groups are covered - invertebrates; fish; reptiles and amphibians; birds; marine mammals; primates; and other mammals. Within each taxonomic group, four scientific disciplines are explored - conservation; reproductive physiology; behaviour; and captive design. Captive and wild status are given for all groups. A major reference work for anyone involved in this increasingly important subject area.
