Wild Pigs in the United States by John J. Mayer,I. Lehr Brisbin Pdf

With an estimated population of at least 500,000 distributed across nineteen states, the wild-living pig (Sus scrofa) is the most abundant free-ranging introduced ungulate in the United States. Until now, however, little has been known about the wild pig on a national scale, despite its abundance and significance as both a pest and a game animal. Whereas previous studies have been regional in scope, Wild Pigs in the United States is the most comprehensive work available on wild pig history, current status, comparative morphology, and other subjects important to the species' management and control. The information in this volume relates to the country's three prevalent wild pig types: the introduced Eurasian wild boar, the feral (once domestic, now wild) hog, and hybrids of the two. The first section of the book presents a history of wild pigs in this country-their origins; when, where, and by whom they were first introduced; and their subsequent dispersal. John J. Mayer and I. Lehr Brisbin, Jr. then develop specific criteria, based on taxonomic principles, for differentiating between the wild pig types. Employing numerous illustrations, graphs, and tables, they analyze and compare morphometric and discrete characters of the skull, external body dimensions and proportions, coat colorations patterns, and hair structure and form. A report on the status of wild pig populations in the United States (as of 1991) completes the volume. To profile the present ranges, habitats, and morphotypic makeups of wild pigs, the authors conducted two national surveys--in 1981 and 1988--among private individuals and federal and state personnel. Their report is also based on other recent wild pig studies and additional information from survey respondents. The book's reference section is particularly valuable, for its lists all sources consulted as well as the names and addresses of authorities the authors interviewed or with whom they corresponded. Aided by the book's wealth of current data, biologists and wildlife managers can make informed decisions about such issues as state versus private ownership of wild pig populations and the status of wild pigs as pests or game animals. In addition, hunters and sportsmen, zoologists, and even specialized historians and archaeologists will find Wild Pigs in the United States useful and informative.

California Maritime Archaeology by Raab,Cassidy Pdf

San Clemente Island is a microcosm of California coastal archaeology from prehistoric through historic times—not only because of the extensiveness of its archaeological remains but because those remains have been so well preserved. In California Maritime Archaeology, the authors use the island as a platform to explore evidence of early seafaring, colonization, paleoenvironmental change, and cultural interaction along the California coast. They make a strong case that San Clemente island should be seen as a kind of "California archaeological Galapagos," offering an extraordinary variety of ancient life as well as surprising information about prehistoric hunter-gatherers of the northern Pacific. The authors' two decades of research have resulted in this rich cultural history that defies widespread assumptions about California's ancient maritime history.

Ecosystems of California by Harold Mooney,Erika Zavaleta Pdf

This long-anticipated reference and sourcebook for California’s remarkable ecological abundance provides an integrated assessment of each major ecosystem type—its distribution, structure, function, and management. A comprehensive synthesis of our knowledge about this biologically diverse state, Ecosystems of California covers the state from oceans to mountaintops using multiple lenses: past and present, flora and fauna, aquatic and terrestrial, natural and managed. Each chapter evaluates natural processes for a specific ecosystem, describes drivers of change, and discusses how that ecosystem may be altered in the future. This book also explores the drivers of California’s ecological patterns and the history of the state’s various ecosystems, outlining how the challenges of climate change and invasive species and opportunities for regulation and stewardship could potentially affect the state’s ecosystems. The text explicitly incorporates both human impacts and conservation and restoration efforts and shows how ecosystems support human well-being. Edited by two esteemed ecosystem ecologists and with overviews by leading experts on each ecosystem, this definitive work will be indispensable for natural resource management and conservation professionals as well as for undergraduate or graduate students of California’s environment and curious naturalists.
