Animal Stress Biology: Applications across Natural and Man-made Systems provides the fundamental aspects of stress endocrinology with a major focus on the applications of stress research in animal welfare. Stress plays an integral part in the maintenance of homeostasis in animals and is a useful measure of animal responses to management interventions across natural, agricultural, and clinical settings. Written by experts in the field of animal stress biology, this book is systematically structured for easy student navigation. Early sections introduce the basics of animal stress biology in major taxa. Latter sections explore how animal stress varies across species and settings, and how this research can be applied to improve animal welfare. Animal Stress Biology incorporates chapter summaries, key term definitions, global case studies, and discussion sections to ensure content is accessible to all audiences. It is an indispensable resource to students and early career professionals, as well as specialists in agriculture, zoos, clinical research settings, and resource management who are interested in learning more about animal stress and welfare.
