Ecology and Behaviour of North American Black Bears

Pages : 236
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
Beginning in 1872 with the establishment of Yellowstone, national parks were set aside to preserve for future generations the most spectacular and inspirational features of the country. The best representative examples were sought out of major ecosystems, such as Yosemite, geologic forms, such as the Grand Canyon, archaeological sites, such as Mesa Verde, and scenes of human events, such as Gettysburg. But one type of habitat--the desert--was overlooked until travel writers and the Automobile Age began to change Americans' perceptions about desert landscapes. As the National Park Service began to explore the better-known Mojave and Colorado Deserts of southern California during the 1920s for a possible desert park, many agency leaders still held the same negative image of arid lands shared by many Americans--that they are hostile environments and largely useless. But one wealthy woman--Minerva Hamilton Hoyt, from Pasadena--came forward, believing in the value of the desert, and convinced President Franklin D. Roosevelt to establish a national monument that would protect the unique and iconic Joshua trees and other desert flora and fauna. Thus was Joshua Tree National Monument officially established in 1936, and when the area later was expanded in 1994, it became Joshua Tree National Park. Since 1936 the National Park Service and a growing cadre of environmentalists and recreationalists have fought to block ongoing proposals from miners, ranchers, private landowners, and real estate developers who historically have refused to accept the idea that desert might be suitable for anything other than their consumptive activities. Joshua Tree National Park, even with its often-conflicting land uses, is more popular today than ever, serving more than one million visitors per year who find the desert to be a place worthy of respect and preservation.

Speaking of Bears

Pages : 301
Book Description
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.
