Reprint of the original, first published in 1874.

This book further develops the interventionist literature on wild animal suffering using different theoretical frameworks, including some that have never previously been used to ground our positive duties to wild animals. Though we’ve always known that the wild is a nasty place where predators lethally attack prey, only recently have most animal ethicists come to realize that most wild animals fail to flourish. In fact, what we know about wild animal reproduction suggests that the majority of sentient beings born into the world may not even live lives worth living. It’s not unreasonable for one to initially respond to the above with a sense of depressed resignation, but a growing number of ethicists believe that we both can and should intervene. The purpose of this book is to further develop the interventionist literature by bringing together philosophers who agree that we have significant duties to help wild animals, but who use different theoretical frameworks, or who disagree about the details, e.g., about the reasons that ground our obligations to help wild animals, about how those obligations should be classified, about the content of our obligations, about the means we should use to fulfill our obligations, etc. This book will be an invaluable resource for scholars, researchers and students of animal ethics, animal welfare, environmental ethics, philosophy, and sustainability. It was originally published as a special issue of the journal Ethics, Policy & Environment.

Gary Wobeser's successful book from 1994 has been completely updated and enlarged in a new second edition. An in-depth overview of the available techniques for the investigation and management of disease in free-ranging animals is provided. The subjects are illustrated with examples drawn from around the world, with emphasis on the special requirements involved in working with wild animals. The book draws on the author’s training as a wildlife biologist.

The interrelationship between wild animal, domestic animals and human health is appreciated now more than ever before. This is because of the recognition of the involvement of wild animals in diseases of humans and domestic animals, the impact of disease on wildlife management and conservation biology, recognition of new forms of environmental contamination, and academic interest in disease as an ecological factor. This is the first introductory level book about disease in wild animals that deals with basic subjects such as the nature of disease, what causes disease, how disease is described and measured, how diseases spread and persist and the effects of disease on individual animals and populations. In contrast to authors of many other veterinary books, Gary A. Wobeser takes a more general approach to health in wild animals, recognizing that disease is one ecological factor among many and that disease can never be considered satisfactorily in isolation. Rather than focus on individual causative agents and their effect on the individual animal, the emphasis is on why disease occurred, and on the complex interactions that occur among disease agents, the environment and host populations. Written by a leading researcher in wildlife diseases, this book will fill a knowledge gap for those called to work with disease in wild animals who lack experience or training in the general features of disease as they relate to wild animals. Veterinarians, ecologists, wildlife biologists, population biologists and public health workers will find this book invaluable.

Wild Animals in Captivity covers some of the mistaken notions concerning the conditions of animals in captivity, most of which are the result of an anthropomorphic approach to the subject. This book is composed of 12 chapters and starts with an overview of the historical development of zoological gardens. The succeeding chapters deal with the territorial requirements and sociological factors in the wild life. These topics are followed by discussions of the wild animal's transition behavior from freedom to captivity; the physiological and psychological aspects of animal captivity; and the motive and situation of animal escapes. Other chapters emphasize the physical and biological environment of animals in captivity. The final chapters examine the problems related to feeding patterns, and nutrition of captive animals. These chapters also explore the relationship between human and animal, their capacity to be tamed and trained. This book will prove useful to zoologists.
