Available in PDF, EPUB and Kindle. Book excerpt: As majestic as they are dangerous, and as timeless as they are current, bears continue to captivate readers. Speaking of Bears is not your average collection of stories. Rather it is the history, compiled from interviews with over 100 individuals, of how Yosemite, Sequoia, and Kings Canyon National Parks, all in California’s Sierra Nevada, created a human-bear problem so bad that there were eventually over 2,000 incidents in a single year. It then describes the pivotal moments during which park employees used trial-and-error, conducted research, invented devices, collaborated with other parks, and found funding to get the crisis back under control. Speaking of Bears is for bear lovers, national park buffs, historians, wildlife managers, biologists, policy and grant-makers, and anyone who wants to know the who, what, where, when, and why of what once was a serious human-bear problem, and the path these parks took to correct it. Although these Sierran parks had some of the worst black bear problems in the country, hosted much of the research, and invented the bulk of the technological solutions, they were not the only ones. For that reason, intertwining stories from several other parks including Yellowstone, the Great Smoky Mountains, and Banff-Canada are included. For anyone seeking solutions to human-wildlife conflicts throughout the world, the lessons-learned are invaluable and widely applicable.

Available in PDF, EPUB and Kindle. Book excerpt: As human-modified landscapes now predominate globally, understanding the role of novel habitats in modifying animal behavior is increasingly important. Such new conditions can change animal foraging behavior, with important implications for individual condition, and biological aging. American black bears (Ursus americanus) are long-lived opportunistic omnivores that exhibit highly plastic foraging strategies, utilize seasonal hibernation, and are increasingly found in developing landscapes. As such, bears may alter their behavior to take advantage of differing availabilities of food subsidies, with important consequences at the individual- and population-level. My dissertation investigates the interactions of habitat and human activity on the foraging and aging ecology of black bears. Using stable isotopes to analyze diet, and telomeres as a molecular marker for biological aging, I examined bears at multiple scales in Colorado and Wisconsin. Each chapter of this dissertation is written (and formatted) as a manuscript for publication in a scholarly journal. Chapter 1 (published in Biological Conservation) investigated bear foraging throughout the Colorado landscape, and found that levels of human activity drove bear diet, and foraging on subsidies increased risk of conflict. Chapter 2 (in review at Evolutionary Ecology) explored the relative importance of such environmental factors and individual characteristics on biological aging in these Colorado black bears, and discovered a latitudinal pattern in telomere length that is likely driven by habitat differences. Chapter 3 (in review at Journal of Applied Ecology) characterized the high reliance of northern Wisconsin black bears on intentionally provisioned subsidies in the form of bear bait -- over 40% of their lifetime diet was derived from bait sources. Finally, Chapter 4 (prepared for submission to Functional Ecology) inspected a small population of longitudinally sampled black bears in southwestern Colorado to consider how foraging and hibernation influence stress and biological aging, and found that hibernation length slowed biological aging, but that foraging on subsidies could shorten hibernation. Overall, the work here demonstrates the remarkable habituation of black bears to food subsidies at multiple scales, and how accompanying changes in behavior and hibernation characteristics may have associated effects at the population and molecular levels, and suggests strategies for managing such populations.

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.

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.
Download or read book Ecology written by Charles J. Krebs and published by Benjamin-Cummings Publishing Company. This book was released on 2001 with total page 695 pages. Available in PDF, EPUB and Kindle. Book excerpt: This best-selling majors ecology book continues to present ecology as a series of problems for readers to critically analyze. No other text presents analytical, quantitative, and statistical ecological information in an equally accessible style. Reflecting the way ecologists actually practice, the book emphasizes the role of experiments in testing ecological ideas and discusses many contemporary and controversial problems related to distribution and abundance. Throughout the book, Krebs thoroughly explains the application of mathematical concepts in ecology while reinforcing these concepts with research references, examples, and interesting end-of-chapter review questions. Thoroughly updated with new examples and references, the book now features a new full-color design and is accompanied by an art CD-ROM for instructors. The field package also includes The Ecology Action Guide, a guide that encourages readers to be environmentally responsible citizens, and a subscription to The Ecology Place (www.ecologyplace.com), a web site and CD-ROM that enables users to become virtual field ecologists by performing experiments such as estimating the number of mice on an imaginary island or restoring prairie land in Iowa. For college instructors and students.
