Book Description
What main factors affect mammalian home range size and dynamics? To what extent do constraints on home range characteristics vary between the sexes? This book aims to address these issues by concentrating the authors' expertise and experience in studies of home ranges in general and focusing on their studies of black bears of the Pisgah Forest, North Carolina, in particular. The authors provide an overview of the black bears and methods for their study before discussing concepts of home range, developing predictive habitat quality models, addressing influences of food production on social organization and exploring the mating behaviour of male bears.

Book Description
Bears have fascinated people since ancient times. The relationship between bears and humans dates back thousands of years, during which time we have also competed with bears for shelter and food. In modern times, bears have come under pressure through encroachment on their habitats, climate change, and illegal trade in their body parts, including the Asian bile bear market. The IUCN lists six bears as vulnerable or endangered, and even the least concern species, such as the brown bear, are at risk of extirpation in certain countries. The poaching and international trade of these most threatened populations are prohibited, but still ongoing. Covering all bears species worldwide, this beautifully illustrated volume brings together the contributions of 200 international bear experts on the ecology, conservation status, and management of the Ursidae family. It reveals the fascinating long history of interactions between humans and bears and the threats affecting these charismatic species.

Book Description
Outlining the differences and similarities among the various species of North American bears, this book makes a plea for the preservation of bear habitat that is quickly disappearing. It discusses in detail the natural history (including range, diet, personality traits, breeding and social structure), the present and historical interaction with mankind, and the threats to black, brown and grizzly bears.

Book Description
This book provides an analysis of frequently used research techniques in animal ecology, identifying their limitations and misuses, as well as possible solutions to avoid such pitfalls. The contributors provide an overarching account of central theoretical and methodological controversies. The editors have forged comprehensive presentations of key topics in animal ecology, such as territory and home range estimates, habitation evaluation, population viability analysis, GIS mapping, and measuring the dynamics of societies.

Book Description
Three species of bear inhabit North America: the grizzly, the polar bear, and the black bear. But the American black bear is truly North America's bear, found only in North America. Black bears range from Canada to Mexico, from New England to California. There may be as many as 750,000 black bears roaming the forests and mountains of the continent. With its large population, and with more people moving into black bear territory, it's important that we understand this magnificent animal. Stephen R. Swinburne takes us to where black bears live. He joins biologists in search of bears in the Pennsylvania woods, where a mother bear is examined and her cubs tagged. He visits a "school teacher" for orphaned cubs who teaches them how to survive in the wild. Along the way, he offers his personal observations together with fascinating facts about black bears and their world. (Did you know that in the autumn, black bears consume as much as twenty thousand calories a day? That's equivalent to forty-two hamburgers!) With stunning full-color and archival photographs, this lively book shows how North America's bear behaves and survives.

Book Description
What causes bear attacks? When should you play dead and when should you fight an attacking bear? What do we know about black and grizzly bears and how can this knowledge be used to avoid bear attacks? And, more generally, what is the bear’s future? Bear Attacks is a thorough and unflinching landmark study of the attacks made on men and women by the great grizzly and the occasionally deadly black bear. This is a book for everyone who hikes, camps, or visits bear country–and for anyone who wants to know more about these sometimes fearsome but always fascinating wild creatures.
