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.

A wildlife expert explores what science tells us about animals as unique individuals and why animal personality matters for the human-animal bond and for adaptation in nature. Why are some cats cuddly and others standoffish? Why are some dogs adventuresome, others homebodies? As any pet owner can attest, we feel that the animals we've formed bonds with are unique, as particular (and peculiar) as any human friend or loved one. Recent years have brought an increased understanding of animal intelligence and emotion. But is there a scientific basis for animal personality and individuality, or is this notion purely sentimental? It turns out that science has been reluctant to even broach the subject of individuality until recently. But now, a fundamental shift in scientific understanding is underway, as mainstream scientists begin to accept the idea that animals of all kinds--from beloved beasts like apes and birds to decidedly less cuddly creatures like crabs and spiders--do indeed have individual personalities. In Mousy Cats and Sheepish Coyotes, veteran wildlife expert Dr. John A. Shivik brings us stories from the front lines of this exciting new discipline. Drawing on his scientific training, as well as his storytelling gifts, Shivik serves as an accessible, humorous guide to the emerging body of research on animal personalities. Shivik accompanies researchers who are discovering that each wolf, bear, and coyote has an inherent tendency to favor either its aggressive nature or to shyly avoid conflicts. Some bluebirds are lovers, others are fighters. And some spiders prefer to be loners, while others are sociable. Unique personalities can be discovered in every corner of the animal kingdom--even among microscopic organisms. The array of personality types among all species is only beginning to be described and understood. As Shivik argues, animals' unique personalities are important not only because they determine which animals we bond with. Individual animal traits are also fundamental but still inadequately understood drivers of evolution, adaptation, and species diversity. Ultimately, Mousy Cats and Sheepish Coyotes offers insight into the similarities humans share with animals and presents evidence of an unbroken biological connection from the smallest organisms to Homo sapiens.

North America's fastest mammal, the pronghorn can accelerate explosively from a standing start to a top speed of 60 miles per hour--but it can also cruise at 45 miles per hour for many miles. What accounts for the speed of this extraordinary animal, a denizen of the American outback, and what can be observed of this creature's way of life? And what is it like to be a field biologist dedicating twenty years to studying this species? In Built for Speed, John A. Byers answers these questions as he draws an intimate portrait of the most charismatic resident of the American Great Plains. The National Bison Range in western Montana, established in 1908 to snatch bison from the brink of extinction, also inadvertently rescued the largest known remnant of Palouse Prairie. It is within this grassland habitat--home to meadowlarks, rattlesnakes, bighorn sheep, coyotes, elk, snipe, and a panoply of wildflowers--that Byers observes the pronghorn's life from birth to death (a life often as brief as four days, sometimes as long as fifteen years) and from season to season. Readers will also experience the vicarious pleasures of a biologist who is eager to race a pronghorn in his truck, scrutinize bison dung through binoculars, and peer through the gathering dusk of a rainy evening to count the display dives of snipe. A vivid and memorable tale of a first-rate scientist's twenty-year encounter with a magnificent animal, the story of the pronghorn is also a reminder of the crucial role we can play in preserving the fleeting life of the native American grassland.

The Floor of the Sky Notes Acknowledgments Index Reviews of this book: Byers, a biologist, has studied pronghorns on a refuge in western in Montana for more than 20 years, and this firsthand account of fieldwork in the high-plains grasslands evokes the wonder and beauty of the region as well as the mechanics of how to study such an alert and speedy animal. --Nancy Bent, Booklist John A. Byers is a field biologist who has spent almost a quarter of a century chasing pronghorn antelopes in Montana's National Bison Range. Byers observes his subjects with such patience that he can recognize individual faces the way most people recognize friends and family. He's read John James Audubon and John Muir, and, as he proves with stirring accounts of his experiences in big-sky country, he can spin a phrase with a skill worthy of those master wordsmiths. --Laurence A. Marschall, Natural History Reviews of this book: This is a swift, short take on a fascinating animal. --National Geographic Adventure Byers at all times writes with lucidity and warmth for the animal he has spent literally decades studying...Byers has called our attention to an often overlooked corner of creation: the shortgrass prairie. He urges us--through the strength of his prose and the sincerity of his passion--to conserve that very thing whose absence will be our confounding. --John A. Murray, Bloomsbury Review A Year in the Life of Pronghorn is natural history at its best, a first-person narrative by zoology professor John A. Byers, told with the grace and agility that have made these four-legged Shelby Cobras famous. --Dan R. Barber, Dallas Morning News Byers, professor of zoology at the University of Idaho, has spent 20 years closely observing pronghorn on the National Bison Range in Montana. His account of the animal's ways is thorough and fascinating. --Scientific American This is a book of natural history, rather than an ethological study of a single species, and it brings to mind Frank Fraser Darling's classic study of animal behaviour, A Herd of Red Deer, first published in 1937. In similar style, Byers writes simply and with sensitivity about the ways of life of the pronghorn, and he also brings in his observations and thoughts about the landscape of the prairie and its other inhabitants, from bison to grasshoppers. --Juliet Clutton-Brock, Times Literary Supplement [UK] After describing the basic anatomy of pronghorn, [Byers] details the social system of adult females and their offspring, the feeding and playing behavior of fawns, the behavior of males before and during the rut, and the behavior of males and females after the rut as they prepare for the long winter on the prairie. Throughout, Byers also includes his personal observations of other species that are associated with this region, including snipe, meadowlarks, bison, and elk. With its vivid descriptions of the prairie and the animals that inhabit it, this book is an entertaining read for all audiences. --E. H. Rave, Choice Although a biologist who is obsessed with his subject could spout facts and numbers for hours, Byers suppresses neither his highly poetic sensibility nor his boundless joy in the marvels of life. The result is a work of literature, as when he describes the song of meadowlarks as 'a low flood of burbling that spreads across the prairie like the sheet of light that fireflies make at grass tops after a thunderstorm.' But readers also gain a tremendous sense of pronghorns' lives, down to the tiniest details of how fawns survive. --David Lukas, Los Angeles Times John Byers's Built for Speed is the best modern natural history I know. His profound sense of place, welded to his tenacious observations of the behavior of long-lived individuals, and his knowledge of deep time have exposed the ghosts of predators past on pronghorn. Added pleasure comes from Byers's prose, which is sometimes as thrilling and amusing as watching pronghorn run. You won't find a more passionate exegesis of what it is to be a modern animal behaviorist anywhere. --Patricia Adair Gowaty, PhD, Professor of Ecology, University of Georgia John Byers's beautifully written account of his twenty-year study of pronghorn antelope was sheer pleasure to read. With the eye and empathy of the keenest naturalist, and the voice of a poet, Byers evokes the sights and sounds of the western prairie so vividly that I felt as if I was there in Montana beside him. This splendid book certainly made me want to be. --Sarah Hrdy, author of The Woman that Never Evolved Readers of this book will be transported by its engaging prose into three very different worlds. First, they will gain an appreciation for what fieldwork on large mammals is really like. Second, they will see how there is no substitute for long-term research on marked individuals to gain knowledge on large mammal ecology. Thirdly, they will see a prehistoric world where cheetahs chase pronghorns over the North American Plains, and will be invited to think about how those distant events may affect the biology of modern-day pronghorn. --Marco Festa-Bianchet, Professeur, Ecologie, Universite de Sherbrooke Listen to this serenade for American wild life sung by a biologist who has spend an unimaginable amount of time following his favorite animal, the pronghorn. With great love and humor, John Byers describes the ins and outs of this unassuming but remarkable animal's life while effortlessly educating us about ecology and evolution. --Frans de Waal, author of The Ape and the Sushi Master (BasicBooks, 2001).

The key aim of this book is to explore the global conservation and management of sharks. There has been a rapid decline in populations of many shark species, while new science has emerged of the critical role they play in marine ecosystems. However, the authors show that conservation law and policy have been slow to develop, with only a small number of iconic species being protected worldwide. The increase in fishing impact – primarily through shark finning and by-catch - has led to shark conservation receiving greater international attention in recent years. The book explores our current knowledge and status of the law and science in relation to sharks with a particular focus on improving frameworks for their conservation and management. Recent trends are analysed, including shark finning bans that have been put in place in several countries, the widening number of nations establishing shark sanctuaries and the growth of shark-based tourism. The efficacy of current listing processes for endangered species and fisheries regulations is also examined. Tourism is explored as an alternative to fishing and the risks and impacts associated with this industry are analysed. Contributors include leading authorities from universities and conservation organizations in North America, Europe and Australia. A common theme is to emphasise the importance of collaborative governance between various interest groups and the need for inter-disciplinary research and management approaches that are necessary to address the decline in sharks.

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, AndrFs 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.

"This is the book to have on urban bird ecology. It summarizes the state of the science, highlighting the strength and breadth of the growing body of urban bird research around the world. More importantly, it documents how the field of urban bird ecology is moving beyond the study of pattern to address the ecological and evolutionary processes that impact birds in complex urban mosaics."—Steward T.A. Pickett, Cary Institute of Ecosystem Studies "Urban ecosystems are under-studied environments offering unique opportunities to study species adaptability, persistence, and assembly. This book presents creative contributions from leading researchers who explore how urbanization affects avian ecology and how birds and people interact."—Steven Beissinger, UC Berkeley

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.
