This book was released on 2010 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because American black bears (Ursus americanus) are an important game species in Arizona and are endangered in México, an understanding of the population structure, gene flow, and connectivity are important for effective management. Black bears inhabit coniferous and broadleaf deciduous woodlands in southern Arizona and northern México, usually in sky islands (sky islands are mountains that rise from the desert and are isolated from each other). Because a single sky island is too small to support a viable bear population, black bears move through desert lowlands to reach other sky islands. My objective was to assess genetic structure, connectivity, and conservation implications for sky island black bears in southern Arizona and northern México. I addresses 4 components of bear ecology and genetics: a literature review of genetic information available for black bears in North America; the use of 2 mitochondrial DNA genes (Control Region and ATP synthase protein 8) to study the phylogenetic relationship of black bears from the sky islands of southern Arizona and northern México relative to all North America; the use of 10 microsatellite loci to detect the current genetic structure of black bears in the sky islands in Arizona and northern México; and the use of non-invasive samples collected from the field to determine bear density and population size for black bear in Sierra San Luis, Sonora, México. These studies provide information that can be used by biologists, land managers, and others to assist in the conservation of black bears and their habitat.

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 excerpt: The American black bear (Ursus americanus) of north central Utah occupies a habitat used for livestock grazing, logging, heavy recreational uses, and human habitation. We began this study in 1985 to determine the food habits, habitat use patterns, home range sizes, productivity, and general health of this population. Grasses and forbs provided the bulk of the spring diets. Animal matter was also a major component of their yearly diet. Litter size averaged 1.7 cubs per adult female during the 10 years of this study. Home range sizes for males was 3 times larger than for females. Five subadult males dispersed from our study area over distances ranging from 12 miles (20 km) to 57 miles (91 km). All were dead within 3 years. The purpose of this study was to answer basic questions and provide management recommendations to ensure the Hobble Creek-Diamond Fork black bear population will endure for many, many years. These black bears live near a human population of 200,000 and stay almost conflict-free. We explored reasons why they stay good neighbors.
Download or read book Wild Carnivores of New Mexico written by Jean-Luc E. Cartron and published by University of New Mexico Press. This book was released on 2024-02-15 with total page 1145 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this first-ever landmark study of New Mexico's wild carnivores, Jean-Luc E. Cartron and Jennifer K. Frey have assembled a team of leading southwestern biologists to explore the animals and the major issues that shape their continued presence in the state and region. The book includes discussions on habitat, evolving or altered ecosystems, and new discoveries about animal behavior and range, and it also provides details on the distribution, habitat associations, life history, population status, management, and conservation needs of individual carnivore species in New Mexico. Like Cartron's award-winning Raptors of New Mexico, Wild Carnivores of New Mexico shares the same emphasis on scientific rigor and thoroughness, high readability, and visual appeal. Each chapter is illustrated with numerous color photographs to help readers visualize unique morphological or life-history traits, habitat, research techniques, and management and conservation issues.
