Book Description
The story of the recovery of mountain lions in the Black Hills of South Dakota. Mountain lions, sometimes called pumas or cougars, were once spread throughout the United States, occupying all 48 of the contiguous states. By the 1960s, though, they were almost extinct in central and eastern North America. In Mountain Lions of the Black Hills, Dr. Jonathan A. Jenks, who, along with his team of graduate students, has tracked over 200 of these fascinating predators, tells the complex story of the big cats’ lives in the northern Great Plains. Jenks reports on mountain lion population dynamics, diet, nutrition, diseases, behavior, and genetics. He explores the impact of a changing prey base on population growth and decline, movements within and away from the region, and hunting on the species; discusses interactions between the cats and livestock; and examines local people’s evolving perceptions of mountain lions. Throughout, Jenks explores how we can balance conservation techniques with the needs of humans. Providing a unique look into how a large, secretive predator recolonized an isolated region of North America, Mountain Lions of the Black Hills is required reading for wildlife professionals. A captivating text for anyone struck by the wild majesty of these big cats, this book provides invaluable data upon which to make sound management decisions in the Great Plains and beyond.

Book Description
What determines where a species lives? And what determines its abundance? This book takes a fresh approach to some of the classic questions in ecology. Despite great progress in the twentieth century much more remains to be done before we can provide full answers to these questions. The methods described and deployed in this book point the way forward. The core message of the book is that the key insights come from understanding what determines population growth rate, and that application of this approach will make ecology a more predictive science. Topics covered include population regulation, density-dependence, the ecological niche, resource and interference competition, habitat fragmentation and the ecological effects of environmental stress, together with applications to conservation biology, wildlife management, human demography and ecotoxicology. After a substantial introduction by the editors the book brings together contributions from leading scientists from Australia, New Zealand, North America, Europe and the U.K.

Book Description
The wolf is an adept killer, able to take down prey much larger than itself. While adapted to hunt primarily hoofed animals, a wolf - or especially a pack of wolves - can kill individuals of just about any species. Combining behavioral data, thousands of hours of original field observations, research in the literature, a wealth of illustrations, and - in the e-book edition and online - video segments from cinematographer Robert K. Landis, the authors create a compelling and complex picture of these hunters.

Book Description
In just the last few years, behavioral ecologists have begun to address issues in conservation biology. This volume is the first attempt to link these disciplines formally. Here leading researchers explore current topics in conservation biology and discuss how behavioral ecology can contribute to a greater understanding of conservation problems and conservation intervention programs. In each chapter, the authors identify a conservation issue, review the ways it has been addressed, review behavioral ecological data related to it, including their own, evaluate the strengths and weaknesses of the behavioral ecological approach, and put forward specific conservation recommendations. The chapters juxtapose different studies on a wide variety of taxonomic groups. A number of common themes emerge, including the ways in which animal mating systems affect population persistence, the roles of dispersal and inbreeding avoidance for topics such as reserve design and effective population size, the key role of humans in conservation issues, and the importance of baseline data for conservation monitoring and modeling attempts. Each chapter sheds new light on conservation problems, generates innovative avenues of interdisciplinary research, and shows how conservation-minded behavioral ecologists can apply their expertise to some of the most important questions we face today.

Book Description
Large Carnivores and the Conservation of Biodiversity brings together more than thirty leading scientists and conservation practitioners to consider a key question in environmental conservation: Is the conservation of large carnivores in ecosystems that evolved with their presence equivalent to the conservation of biological diversity within those systems? Building their discussions from empirical, long-term data sets, contributors including James A. Estes, David S. Maehr, Tim McClanahan, Andrès J. Novaro, John Terborgh, and Rosie Woodroffe explore a variety of issues surrounding the link between predation and biodiversity: What is the evidence for or against the link? Is it stronger in marine systems? What are the implications for conservation strategies? Large Carnivores and the Conservation of Biodiversity is the first detailed, broad-scale examination of the empirical evidence regarding the role of large carnivores in biodiversity conservation in both marine and terrestrial ecosystems. It contributes to a much more precise and global understanding of when, where, and whether protecting and restoring top predators will directly contribute to the conservation of biodiversity. Everyone concerned with ecology, biodiversity, or large carnivores will find this volume a unique and thought-provoking analysis and synthesis.
