We studied survival and causes of mortality of radiocollared cougars (Puma concolor) on the Greater Yellowstone Northern Range (GYNR) prior to (1987-1994) and after wolf (Canis lupus) reintroduction (1998-2005) and evaluated temporal, spatial, and environmental factors that explain variation in adult, subadult, and kitten survival. Using Program MARK and multimodel inference, we modeled cougar survival based on demographic status, season, and landscape attributes. Our best models for adult and independent subadults indicated that females survived better than males and survival increased with age until cougars reached older ages. Lower elevations and increasing density of roads, particularly in areas open to cougar hunting north of Yellowstone National Park (YNP), increased mortality risks for cougars on the GYNR. Indices of ungulate biomass, cougar and wolf population size, winter severity, rainfall, and individual characteristics such as the presence of dependent young, age class, and use of Park or Wilderness were not important predictors of survival. Kitten survival increased with age, was lower during winter, increased with increasing minimum estimates of elk calf biomass, and increased with increasing density of adult male cougars. Using our best model, we mapped adult cougar survival on the GYNR landscape. Results of receiver operating characteristic (ROC) analysis indicated a good model fit for both female (area under the curve [AUC]=0.81, 95%CI=0.70?0.92, n=35 locations) and male cougars (AUC=0.84, 95%CI=0.74-0.94, n=49 locations) relative to hunter harvest locations in our study area. Using minimum estimates of survival necessary to sustain the study population, we developed a source-sink surface and we identify several measures that resource management agencies can take to enhance cougar population management based on a source-sink strategy.

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.

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.

"This is one stirring account of one stirring journey: the trek of a fellow creature through a hostile, man-made world--and through our imaginations." --Bill McKibben, author of EAARTH: MAKING A LIFE ON A TOUGH NEW PLANET Late one June night in 2011, a large animal collided with an SUV cruising down a Connecticut parkway. The creature appeared as something out of New England's forgotten past. Beside the road lay a 140-pound mountain lion. Speculations ran wild, the wildest of which figured him a ghostly survivor from a bygone century when lions last roamed the eastern United States. But a more fantastic scenario of facts soon unfolded. The lion was three years old, with a DNA trail embarking from the Black Hills of South Dakota on a cross-country odyssey eventually passing within thirty miles of New York City. It was the farthest landbound trek ever recorded for a wild animal in America, by a barely weaned teenager venturing solo through hostile terrain. William Stolzenburg retraces his two-year journey--from his embattled birthplace in the Black Hills, across the Great Plains and the Mississippi River, through Midwest metropolises and remote northern forests, to his tragic finale upon Connecticut's Gold Coast. Along the way, the lion traverses lands with people gunning for his kind, as well as those championing his cause. Heart of a Lion is a story of one heroic creature pitting instinct against towering odds, coming home to a society deeply divided over his return. It is a testament to the resilience of nature, and a test of humanity's willingness to live again beside the ultimate symbol of wildness.

After encountering mountain lion tracks near her home outside Yellowstone National Park, Leslie Patten began a journey to learn above these elusive, unseen animals by collecting anecdotal information and then interviewing biologists, professional trackers, houndsmen, and conservationists.

From the ancient Egyptian cat goddess, Bastet, to the prophet Muhammad’s favorite cat, Muezza, and our contemporary obsession with online cat videos, felines have long held a place of honor in their human counterparts’ homes and cultures. But the domestic cat is just one of many feline species, and in The Wild Cat Book cat experts Fiona and Mel Sunquist introduce us to the full panoply of the purring, roaring feline tribe. Illustrated throughout with Terry Whittaker’s spectacular color photographs as well as unique photos from biologists in the field—some the highest quality images ever captured of exceptionally rare species—The Wild Cat Book not only tantalizes with the beauty of cats, but also serves as a valuable and accessible reference on cat behavior and conservation. Comprehensive entries for each of the thirty-seven cat species include color distribution maps and up-to-date information related to the species’ IUCN conservation and management statuses, while informative sidebars reveal why male lions have manes (and why dark manes are sexiest), how cats see with their whiskers, the truth behind our obsession with white lions and tigers, and why cats can’t be vegetarians. The Wild Cat Book also highlights the grave threats faced by the world’s wild cats—from habitat destruction to human persecution. From the extraordinary acrobatics of the arboreal margay—able to cling to a tree branch by a single paw thanks to its unusually flexible ankles—to modern declines in African lion populations, The Wild Cat Book is an instructive and revealing ode to felines of every size and color. Combining science, behavioral observations, and stunning photography, this book will captivate cat fanciers the world over.

In this first-ever landmark study of New Mexico's wild carnivores, Jean-Luc E. Cartron and Jennifer K. Frey have assembled a team of leading southwestern biologists to explore the animals and the major issues that shape their continued presence in the state and region. The book includes discussions on habitat, evolving or altered ecosystems, and new discoveries about animal behavior and range, and it also provides details on the distribution, habitat associations, life history, population status, management, and conservation needs of individual carnivore species in New Mexico. Like Cartron's award-winning Raptors of New Mexico, Wild Carnivores of New Mexico shares the same emphasis on scientific rigor and thoroughness, high readability, and visual appeal. Each chapter is illustrated with numerous color photographs to help readers visualize unique morphological or life-history traits, habitat, research techniques, and management and conservation issues.

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.
