Michael Allaby has thoroughly revised this bestselling volume, offering the most authoritative and up-to-date zoology dictionary available today. Allaby covers all aspects of the study of animals in more than 5,250 clearly written entries--many new to this edition, including alarm pheromone, Fick's laws, manometer, and synanthrope. Illustrated with many line drawings, the book defines terms from animal behavior, evolution, earth history, zoogeography, genetics, and physiology, provides full taxonomic coverage of arthropods and other invertebrates, fish, reptiles, amphibians, birds, and mammals, and introduces new material on behavioral ecology and conservation biology. In many entries, he recommends web links, which are kept up to date through the Dictionary of Zoology's companion website. Finally, the book includes detailed appendices covering the universal genetic code, endangered animals, the geologic time scale, and SI units. An invaluable dictionary for students of zoology and the related fields of biological and biomedical sciences, A Dictionary of Zoology is also ideal for amateur naturalists and anyone with an interest in animals.
