Available in PDF, EPUB and Kindle. Book excerpt: The cougar is one of the most beautiful, enigmatic, and majestic animals in the Americas. Eliciting reverence for its grace and independent nature, it also triggers fear when it comes into contact with people, pets, and livestock or competes for hunters’ game. Mystery, myth, and misunderstanding surround this remarkable creature. The cougar’s range once extended from northern Canada to the tip of South America, and from the Pacific to the Atlantic, making it the most widespread animal in the western hemisphere. But overhunting and loss of habitat vastly reduced cougar numbers by the early twentieth century across much of its historical range, and today the cougar faces numerous threats as burgeoning human development encroaches on its remaining habitat. When Maurice Hornocker began the first long-term study of cougars in the Idaho wilderness in 1964, little was known about this large cat. Its secretive nature and rarity in the landscape made it difficult to study. But his groundbreaking research yielded major insights and was the prelude to further research on this controversial species. The capstone to Hornocker’s long career studying big cats, Cougar is a powerful and practical resource for scientists, conservationists, and anyone with an interest in large carnivores. He and conservationist Sharon Negri bring together the diverse perspectives of twenty-two distinguished scientists to provide the fullest account of the cougar’s ecology, behavior, and genetics, its role as a top predator, and its conservation needs. This compilation of recent findings, stunning photographs, and firsthand accounts of field research unravels the mysteries of this magnificent animal and emphasizes its importance in healthy ecosystem processes and in our lives.

Available in PDF, EPUB and Kindle. Book excerpt: Yellowstone Cougars examines the effect of wolf restoration on the cougar population in Yellowstone National Park—one of the largest national parks in the American West. No other study has ever specifically addressed the theoretical and practical aspects of competition between large carnivores in North America. The authors provide a thorough analysis of cougar ecology, how they interact with and are influenced by wolves—their main competitor—and how this knowledge informs management and conservation of both species across the West. Of practical importance, Yellowstone Cougars addresses the management and conservation of multiple carnivores in increasingly human-dominated landscapes. The authors move beyond a single-species approach to cougar management and conservation to one that considers multiple species, which was impossible to untangle before wolf reestablishment in the Yellowstone area provided biologists with this research opportunity. Yellowstone Cougars provides objective scientific data at the forefront of understanding cougars and large carnivore community structure and management issues in the Greater Yellowstone Ecosystem, as well as in other areas where wolves and cougars are reestablishing. Intended for an audience of scientists, wildlife managers, conservationists, and academics, the book also sets a theoretical precedent for writing about competition between carnivorous mammals.
Download or read book Yellowstone Wolves written by Douglas W. Smith and published by University of Chicago Press. This book was released on 2020-12-28 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: This beautifully illustrated volume on the Yellowstone Wolf Project includes an introduction by Jane Goodall and an exclusive online documentary. The reintroduction of wolves to Yellowstone National Park was one of the greatest wildlife conservation achievements of the twentieth century. Eradicated after the park was first established, these iconic carnivores returned in 1995 when the US government reversed its century-old policy of extermination. In the intervening decades, scientists have built a one-of-a-kind field study of these wolves, their behaviors, and their influence on the entire ecosystem. Yellowstone Wolves tells the incredible story of the Yellowstone Wolf Project, as told by the people behind it. This wide-ranging volume highlights what has been learned in the decades since reintroduction, as well as the unique blend of research techniques used to gain this knowledge. We learn about individual wolves, population dynamics, wolf-prey relationships, genetics, disease, management and policy, and the rippling ecosystem effects wolves have had on Yellowstone’s wild and rare landscape. Featuring a foreword by Jane Goodall, beautiful images, a companion online documentary by celebrated filmmaker Bob Landis, and contributions from more than seventy wolf and wildlife conservation luminaries from Yellowstone and around the world, Yellowstone Wolves is an informative and beautifully realized celebration of the extraordinary Yellowstone Wolf Project.

Book excerpt: Trophic cascades—the top-down regulation of ecosystems by predators—are an essential aspect of ecosystem function and well-being. Trophic cascades are often drastically disrupted by human interventions—for example, when wolves and cougars are removed, allowing deer and beaver to become destructive—yet have only recently begun to be considered in the development of conservation and management strategies. Trophic Cascades is the first comprehensive presentation of the science on this subject. It brings together some of the world’s leading scientists and researchers to explain the importance of large animals in regulating ecosystems, and to relate that scientific knowledge to practical conservation. Chapters examine trophic cascades across the world’s major biomes, including intertidal habitats, coastal oceans, lakes, nearshore ecosystems, open oceans, tropical forests, boreal and temperate ecosystems, low arctic scrubland, savannas, and islands. Additional chapters consider aboveground/belowground linkages, predation and ecosystem processes, consumer control by megafauna and fire, and alternative states in ecosystems. An introductory chapter offers a concise overview of trophic cascades, while concluding chapters consider theoretical perspectives and comparative issues. Trophic Cascades provides a scientific basis and justification for the idea that large predators and top-down forcing must be considered in conservation strategies, alongside factors such as habitat preservation and invasive species. It is a groundbreaking work for scientists and managers involved with biodiversity conservation and protection.

This book was released on 2013-10-04 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using Science to Improve the BLM Wild Horse and Burro Program: A Way Forward reviews the science that underpins the Bureau of Land Management's oversight of free-ranging horses and burros on federal public lands in the western United States, concluding that constructive changes could be implemented. The Wild Horse and Burro Program has not used scientifically rigorous methods to estimate the population sizes of horses and burros, to model the effects of management actions on the animals, or to assess the availability and use of forage on rangelands. Evidence suggests that horse populations are growing by 15 to 20 percent each year, a level that is unsustainable for maintaining healthy horse populations as well as healthy ecosystems. Promising fertility-control methods are available to help limit this population growth, however. In addition, science-based methods exist for improving population estimates, predicting the effects of management practices in order to maintain genetically diverse, healthy populations, and estimating the productivity of rangelands. Greater transparency in how science-based methods are used to inform management decisions may help increase public confidence in the Wild Horse and Burro Program.

Download or read book The Predator Paradox written by John A. Shivik and published by Beacon Press. This book was released on 2014-05-13 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: An expert in wildlife management tells the stories of those who are finding new ways for humans and mammalian predators to coexist. Stories of backyard bears and cat-eating coyotes are becoming increasingly common—even for people living in non-rural areas. Farmers anxious to protect their sheep from wolves aren’t the only ones concerned: suburbanites and city dwellers are also having more unwanted run-ins with mammalian predators. And that might not be a bad thing. After all, our government has been at war with wildlife since 1914, and the death toll has been tremendous: federal agents kill a combined ninety thousand wolves, bears, coyotes, and cougars every year, often with dubious biological effectiveness. Only recently have these species begun to recover. Given improved scientific understanding and methods, can we continue to slow the slaughter and allow populations of mammalian predators to resume their positions as keystone species? As carnivore populations increase, however, their proximity to people, pets, and livestock leads to more conflict, and we are once again left to negotiate the uneasy terrain between elimination and conservation. In The Predator Paradox, veteran wildlife management expert John Shivik argues that we can end the war while still preserving and protecting these key species as fundamental components of healthy ecosystems. By reducing almost sole reliance on broad scale “death from above” tactics and by incorporating nonlethal approaches to managing wildlife—from electrified flagging to motion-sensor lights—we can dismantle the paradox, have both people and predators on the landscape, and ensure the long-term survival of both. As the boundary between human and animal habitat blurs, preventing human-wildlife conflict depends as much on changing animal behavior as on changing our own perceptions, attitudes, and actions. To that end, Shivik focuses on the facts, mollifies fears, and presents a variety of tools and tactics for consideration. Blending the science of the wild with entertaining and dramatic storytelling, Shivik’s clear-eyed pragmatism allows him to appeal to both sides of the debate, while arguing for the possibility of coexistence: between ranchers and environmentalists, wildlife managers and animal-welfare activists, and humans and animals.
