Ecology and Behaviour of North American Black Bears available in PDF, EPUB and Kindle. 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.

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.

This book was released on 2009-12-15. Cougar available in PDF, EPUB and Kindle. 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.
