Zoos are centers of research where scientists conduct studies that would be impossible among animals in the wild state. In some cases, the biologist or psychologist is able to examine carefully elements that can only be imprecise for a wild animal: physiology, longevity, habits, etc. In other situations the zoo observer can watch the interplay between environment and animal and see the various aberrations that may emerge when environment has been changed. For example, certain animals like foxes and hares, which do not normally climb trees, often become climbers in zoo situations. A considerable body of data has been assembled, most of which information is either scattered in technical journals or unpublished. Dr. Hediger, one of the world's foremost authorities on zoos, has gathered this information based upon experiment and observation, and has presented it in terms of territory and space, social relationships, range, escape patterns, physical environment and reactions to it, biological environment, food, excretion, breeding and relationship to man. This material is of prime importance to everyone in the fields of experimental biology, zoology and psychology. It is also a fascinating survey of data for the layman to increase the reader's understanding of zoo animals. 6 tables. 34 figures, including maps, diagrams, and 33 photographs.
