Book Description
A compelling argument that the time has come to use what we know about the fascinating and diverse inner lives of other animals on their behalf Every day we are learning new and surprising facts about just how intelligent and emotional animals are—did you know rats like to play and laugh, and also display empathy, and the ears and noses of cows tell us how they’re feeling? At times, we humans translate that knowledge into compassion for other animals; think of the public outcry against the fates of Cecil the lion or the captive gorilla Harambe. But on the whole, our growing understanding of what animals feel is not resulting in more respectful treatment of them. Renowned animal-behavior expert Marc Bekoff and leading bioethicist Jessica Pierce explore the real-world experiences of five categories of animals, beginning with those who suffer the greatest deprivations of freedoms and choice—chickens, pigs, and cows in industrial food systems—as well as animals used in testing and research, including mice, rats, cats, dogs, and chimpanzees. Next, Bekoff and Pierce consider animals for whom losses of freedoms are more ambiguous and controversial, namely, individuals held in zoos and aquaria and those kept as companions. Finally, they reveal the unexpected ways in which the freedoms of animals in the wild are constrained by human activities and argue for a more compassionate approach to conservation. In each case, scientific studies combine with stories of individual animals to bring readers face-to-face with the wonder of our fellow beings, as well as the suffering they endure and the major paradigm shift that is needed to truly ensure their well-being. The Animals’ Agenda will educate and inspire people to rethink how we affect other animals, and how we can evolve toward more peaceful and less violent ways of interacting with our animal kin in an increasingly human-dominated world.

Book Description
The Endangered Species Act (ESA) is a far-reaching law that has sparked intense controversies over the use of public lands, the rights of property owners, and economic versus environmental benefits. In this volume a distinguished committee focuses on the science underlying the ESA and offers recommendations for making the act more effective. The committee provides an overview of what scientists know about extinctionâ€"and what this understanding means to implementation of the ESA. Habitatâ€"its destruction, conservation, and fundamental importance to the ESAâ€"is explored in detail. The book analyzes: Concepts of speciesâ€"how the term "species" arose and how it has been interpreted for purposes of the ESA. Conflicts between species when individual species are identified for protection, including several case studies. Assessment of extinction risk and decisions under the ESAâ€"how these decisions can be made more effectively. The book concludes with a look beyond the Endangered Species Act and suggests additional means of biological conservation and ways to reduce conflicts. It will be useful to policymakers, regulators, scientists, natural-resource managers, industry and environmental organizations, and those interested in biological conservation.

Book Description
The rapid growth of the American environmental movement in recent decades obscures the fact that long before the first Earth Day and the passage of the Endangered Species Act, naturalists and concerned citizens recognized—and worried about—the problem of human-caused extinction. As Mark V. Barrow reveals in Nature’s Ghosts, the threat of species loss has haunted Americans since the early days of the republic. From Thomas Jefferson’s day—when the fossil remains of such fantastic lost animals as the mastodon and the woolly mammoth were first reconstructed—through the pioneering conservation efforts of early naturalists like John James Audubon and John Muir, Barrow shows how Americans came to understand that it was not only possible for entire species to die out, but that humans themselves could be responsible for their extinction. With the destruction of the passenger pigeon and the precipitous decline of the bison, professional scientists and wildlife enthusiasts alike began to understand that even very common species were not safe from the juggernaut of modern, industrial society. That realization spawned public education and legislative campaigns that laid the foundation for the modern environmental movement and the preservation of such iconic creatures as the bald eagle, the California condor, and the whooping crane. A sweeping, beautifully illustrated historical narrative that unites the fascinating stories of endangered animals and the dedicated individuals who have studied and struggled to protect them, Nature’s Ghosts offers an unprecedented view of what we’ve lost—and a stark reminder of the hard work of preservation still ahead.

Book Description
A single-resource volume of information on the most current and effective techniques of wildlife modeling, Models for Planning Wildlife Conservation in Large Landscapes is appropriate for students and researchers alike. The unique blend of conceptual, methodological, and application chapters discusses research, applications and concepts of modeling and presents new ideas and strategies for wildlife habitat models used in conservation planning. The book makes important contributions to wildlife conservation of animals in several ways: (1) it highlights historical and contemporary advancements in the development of wildlife habitat models and their implementation in conservation planning; (2) it provides practical advice for the ecologist conducting such studies; and (3) it supplies directions for future research including new strategies for successful studies.Intended to provide a recipe for successful development of wildlife habitat models and their implementation in conservation planning, the book could be used in studying wildlife habitat models, conservation planning, and management techniques. Additionally it may be a supplemental text in courses dealing with quantitative assessment of wildlife populations. Additionally, the length of the book would be ideal for graduate student seminar course.Using wildlife habitat models in conservation planning is of considerable interest to wildlife biologists. With ever tightening budgets for wildlife research and planning activities, there is a growing need to use computer methods. Use of simulation models represents the single best alternative. However, it is imperative that these techniques be described in a single source. Moreover, biologists should be made aware of alternative modeling techniques. It is also important that practical guidance be provided to biologists along with a demonstration of utility of these procedures. Currently there is little guidance in the wildlife or natural resource planning literature on how best to incorporate wildlife planning activities, particularly community-based approaches. Now is the perfect time for a synthestic publication that clearly outlines the concepts and available methods, and illustrates them. - Only single resource book of information not only on various wildlife modeling techniques, but also with practical guidance on the demonstrated utility of each based on real-world conditions. - Provides concepts, methods and applications for wildlife ecologists and others within a GIS context. - Written by a team of subject-area experts

Book Description
Why our cats are a danger to species diversity and human health In 1894, a lighthouse keeper named David Lyall arrived on Stephens Island off New Zealand with a cat named Tibbles. In just over a year, the Stephens Island Wren, a rare bird endemic to the island, was rendered extinct. Mounting scientific evidence confirms what many conservationists have suspected for some time—that in the United States alone, free-ranging cats are killing birds and other animals by the billions. Equally alarming are the little-known but potentially devastating public health consequences of rabies and parasitic Toxoplasma passing from cats to humans at rising rates. Cat Wars tells the story of the threats free-ranging cats pose to biodiversity and public health throughout the world, and sheds new light on the controversies surrounding the management of the explosion of these cat populations. This compelling book traces the historical and cultural ties between humans and cats from early domestication to the current boom in pet ownership, along the way accessibly explaining the science of extinction, population modeling, and feline diseases. It charts the developments that have led to our present impasse—from Stan Temple's breakthrough studies on cat predation in Wisconsin to cat-eradication programs underway in Australia today. It describes how a small but vocal minority of cat advocates has campaigned successfully for no action in much the same way that special interest groups have stymied attempts to curtail smoking and climate change. Cat Wars paints a revealing picture of a complex global problem—and proposes solutions that foresee a time when wildlife and humans are no longer vulnerable to the impacts of free-ranging cats.
