Book Synopsis Ecology and Behaviour of North American Black Bears by : Roger A. Powell
Download or read book Ecology and Behaviour of North American Black Bears written by Roger A. Powell and published by Springer Science & Business Media. This book was released on 1997 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Bears of the World by : Vincenzo Penteriani
Download or read book Bears of the World written by Vincenzo Penteriani and published by Cambridge University Press. This book was released on 2020-11-30 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Research Techniques in Animal Ecology by : Luigi Boitani
Download or read book Research Techniques in Animal Ecology written by Luigi Boitani and published by Columbia University Press. This book was released on 2000-06-01 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present biodiversity crisis is rife with opportunities to make important conservation decisions; however, the misuse or misapplication of the methods and techniques of animal ecology can have serious consequences for the survival of species. Still, there have been relatively few critical reviews of methodology in the field. This book provides an analysis of some of the most frequently used research techniques in animal ecology, identifying their limitations and misuses, as well as possible solutions to avoid such pitfalls. In the process, contributors to this volume present new perspectives on the collection, analysis, and interpretation of data. Research Techniques in Animal Ecology is an overarching account of central theoretical and methodological controversies in the field, rather than a handbook on the minutiae of techniques. 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. Striking a careful balance, each chapter begins by assessing the shortcomings and misapplications of the techniques in question, followed by a thorough review of the current literature, and concluding with possible solutions and suggested guidelines for more robust investigations.
Download or read book Cougar written by Maurice Hornocker and published by University of Chicago Press. This book was released on 2009-12-15 with total page 331 pages. 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.
Book Synopsis Spatial Ecology and Captive Behavior of Rehabilitated Black Bears in Utah by : Patrick J. Myers
Download or read book Spatial Ecology and Captive Behavior of Rehabilitated Black Bears in Utah written by Patrick J. Myers and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Animal movements and space use are fundamental components of life and play integral roles in organismal fitness, population dynamics, and the ecology and evolution of species. The heterogeneous distribution of resources and the movement required to access them, results in ecology being a fundamentally spatial concept. Thus, elucidating animal-habitat relationships is a central focus of wildlife ecology and conservation. I utilized GPS technology, resource selection functions, and generalized linear mixed models, to investigate the immediate post-release movements, denning chronology, release-site fidelity, and season-delineated movements, home ranges, and resource use for six, orphaned and rehabilitated black bears (Ursus americanus). This study represents the first application of GPS monitoring and resource selection for rehabilitated black bears. Data from this study provide insights into the activity of released rehabilitated black bear cubs, highlight trends among the release cohort, and illustrate the variability of individual behavior. Results indicate species-typical behaviors, with bears denning shortly after their releases, exhibiting elevated movement rates and dispersals during late-summer, preferential selection for certain habitat types based on season, and no utilization of anthropogenic-resources. One primary concern for large carnivores that have been captive-reared or had prolonged exposure to humans during rehabilitation, is whether they will exhibit natural behaviors after release. Behavior testing in other species has revealed that many traits exhibited in captivity often translate to wild behavior, however this had not yet been investigated for black bears. This study presents the first application of captive behavior tests for the investigation into black bear personality, defined by consistency in the individual differences in behavior across time or context. Through open field, novel object, startle object, and focal-animal sampling, we investigate the potential for personality in six black bear cubs. Results indicate consistency in behavior across five metrics for the bold-shy axis, and eight sampling events measuring responses for the activity axis, thus indicating personality. Analysis to identify correlations to wild activity metrics did not yield strong statistical support, however. Information presented here may provide a framework for future research into black bear personality, its relationship to life-history and ecology, and lend support for rehabilitation practices for orphan bear cubs.
Book Synopsis Tiger Moths and Woolly Bears by : William E. Conner
Download or read book Tiger Moths and Woolly Bears written by William E. Conner and published by Oxford University Press. This book was released on 2009 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: Moths of the family Arctiidae, with their brilliant coloration, spectacular courtship rituals, and bizarre defenses, are wonders of the natural world. Unpalatable by virtue of secondary chemicals acquired from their hostplants, these moths advertise their defenses by their coloration and often mimic butterflies, wasps, bees, stinkbugs, and even cockroaches. They have ears with which they hear the echolocation of bats, and some answer with aposematic warnings, while some may jam the bats' sonar.This book, the first written on this fascinating group, documents how tiger moths and woolly bears-the adults and larvae of the Arctiidae-flourish in a world rife with predators, parasites, and competitors. The contributing authors' accounts, each written by a recognized expert in the field, weave together seminal studies on phylogeny and behavior, natural history, chemical communication, mate choice and sexual selection, chemical ecology, parasite-host relationships, self medication, animal orientation, predator-prey interactions, mimicry, adaptive coloration, speciation, biodiversity, and more.
Book Synopsis Black Bear by : Stephen R. Swinburne
Download or read book Black Bear written by Stephen R. Swinburne and published by Boyds Mills Press. This book was released on 2014-10-07 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Photo Ark written by Joel Sartore and published by National Geographic Books. This book was released on 2017 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book of photography represents National Geographic's Photo Ark, a major cross-platform initiative and lifelong project by photographer Joel Sartore to make portraits of the world's animals -- especially those that are endangered. His message: to know these animals is to save them. Sartore intends to photograph every animal in captivity in the world. He is circling the globe, visiting zoos and wildlife rescue centers to create studio portraits of 12,000 species, with an emphasis on those facing extinction. He has photographed more than 6,000 already and now, thanks to a multi-year partnership with National Geographic, he may reach his goal. This book showcases his animal portraits: from tiny to mammoth, from the Florida grasshopper sparrow to the greater one-horned rhinoceros. Paired with the prose of veteran wildlife writer Douglas Chadwick, this book presents an argument for saving all the species of our planet.
