Available in PDF, EPUB and Kindle. Book excerpt: Historically, rangelands were managed to reduce brush and increase livestock grazing habitat. As with much of the southwestern United States, the seemingly endless "free grass" of Texas rangelands was overgrazed during the late 1800s. Overgrazing reduced fine fuel loads and, combined with disruption in fire regimes, allowed woody plants populations to invade grasslands. Consequently, livestock carrying capacity ultimately declined. Because livestock overgrazing has a central role in land degradation and woody plant encroachment, I analyzed historical livestock numbers to identify potential trends that can generate and be integrated into future hypotheses of land use change. The counties included in four ecoregions of Texas (Edwards Plateau, Lampasas Cut Plains, South Texas, and West Texas) were selected based on the existence of historically uncultivated rangelands. I collected data from the U.S. Census of Agriculture and graphically explored trends in livestock numbers. Although livestock numbers varied across time and by region, three general hypotheses could be identified: a) livestock numbers are direct drivers of degradation and indirect drivers of woody plant encroachment; b) for rangelands threatened by woody plant encroachment, decreasing livestock numbers may be associated with recovery of rangelands in an ecoregion; and, c) given transformation of the landscape from rangelands to woodlands, decreases in livestock numbers over time are related to increases in key indicators of ecosystem health (e.g., ground water flow). This historical analysis provides insight to complex human-ecological interactions and will be used as supporting data for further studies regarding ecosystem health and services.

Available in PDF, EPUB and Kindle. Book excerpt: From reviews of previous editions: “This is the standard reference about Texas mammals.” —Wildlife Activist “A must for anyone seriously interested in the wildlife of Texas.” —Texas Outdoor Writers Association News “[This book] easily fills the role of both a field guide and a desk reference, and is written in a style that appeals to the professional biologist and amateur naturalist alike. . . . [It] should prove useful to anyone with an interest in the mammal fauna of Texas or the southern Great Plains.” —Prairie Naturalist The Mammals of Texas has been the standard reference since the first edition was coauthored by William B. Davis and Walter P. Taylor in 1947. Revised several times over the succeeding decades, it remains the most authoritative source of information on the mammalian wildlife of Texas, with physical descriptions and life histories for 202 species, abundant photographs and drawings, and distribution maps. In this new edition, David J. Schmidly is joined by one of the most active researchers on Texas mammals, Robert D. Bradley, to provide a thorough update of the taxonomy, distribution, and natural history of all species of wild mammals that inhabit Texas today. Using the most recent advances in molecular biology and in wildlife ecology and management, the authors include the most current information about the scientific nomenclature, taxonomy, and identification of species, while also covering significant advances in natural history and conservation.

Book excerpt: "The availability of food is an especially significant issue in zones of conflict because conflictnearly always impinges on the production and the distribution of food, and causes increased competition for food, land and resources Controlling the production of and access to food can also be used as a weapon by protagonists in conflict. The logistics of supply of food to military personnel operating in conflictzones is another important issue. These themes unite this collection, the chapters of which span different geographic areas. This volume will appeal to scholars in a number of different disciplines, including anthropology, nutrition, political science, development studies and international relations, as well as practitioners working in the private and public sectors, who are currently concerned with food-related issues in the field."--Page [4] of cover.

Book excerpt: This book is open access under a CC BY-NC 2.5 license. This book provides an unprecedented synthesis of the current status of scientific and management knowledge regarding global rangelands and the major challenges that confront them. It has been organized around three major themes. The first summarizes the conceptual advances that have occurred in the rangeland profession. The second addresses the implications of these conceptual advances to management and policy. The third assesses several major challenges confronting global rangelands in the 21st century. This book will compliment applied range management textbooks by describing the conceptual foundation on which the rangeland profession is based. It has been written to be accessible to a broad audience, including ecosystem managers, educators, students and policy makers. The content is founded on the collective experience, knowledge and commitment of 80 authors who have worked in rangelands throughout the world. Their collective contributions indicate that a more comprehensive framework is necessary to address the complex challenges confronting global rangelands. Rangelands represent adaptive social-ecological systems, in which societal values, organizations and capacities are of equal importance to, and interact with, those of ecological processes. A more comprehensive framework for rangeland systems may enable management agencies, and educational, research and policy making organizations to more effectively assess complex problems and develop appropriate solutions.

Book excerpt: This volume represents a first attempt at holistically classifying and mapping ecological regions across all three countries of the North American continent. A common analytical methodology is used to examine North American ecology at multiple scales, from large continental ecosystems to subdivisions of these that correlate more detailed physical and biological settings with human activities on two levels of successively smaller units. The volume begins with an overview of North America from an ecological perspective, concepts of ecological regionalization. This is followed by descriptions of the 15 broad ecological regions, including information on physical and biological setting and human activities. The final section presents case studies in applications of the ecological characterization methodology to environmental issues. The appendix includes a list of common and scientific names of selected species characteristic of the ecological regions.

Book excerpt: Ecosystems and Human Well-Being is the first product of the Millennium Ecosystem Assessment, a four-year international work program designed to meet the needs of decisionmakers for scientific information on the links between ecosystem change and human well-being. The book offers an overview of the project, describing the conceptual framework that is being used, defining its scope, and providing a baseline of understanding that all participants need to move forward. The Millennium Assessment focuses on how humans have altered ecosystems, and how changes in ecosystem services have affected human well-being, how ecosystem changes may affect people in future decades, and what types of responses can be adopted at local, national, or global scales to improve ecosystem management and thereby contribute to human well-being and poverty alleviation. The program was launched by United National Secretary-General Kofi Annan in June 2001, and the primary assessment reports will be released by Island Press in 2005. Leading scientists from more than 100 nations are conducting the assessment, which can aid countries, regions, or companies by: providing a clear, scientific picture of the current sta

Book excerpt: By 2050 the world's population is projected to grow by one-third, reaching between 9 and 10 billion. With globalization and expected growth in global affluence, a substantial increase in per capita meat, dairy, and fish consumption is also anticipated. The demand for calories from animal products will nearly double, highlighting the critical importance of the world's animal agriculture system. Meeting the nutritional needs of this population and its demand for animal products will require a significant investment of resources as well as policy changes that are supportive of agricultural production. Ensuring sustainable agricultural growth will be essential to addressing this global challenge to food security. Critical Role of Animal Science Research in Food Security and Sustainability identifies areas of research and development, technology, and resource needs for research in the field of animal agriculture, both nationally and internationally. This report assesses the global demand for products of animal origin in 2050 within the framework of ensuring global food security; evaluates how climate change and natural resource constraints may impact the ability to meet future global demand for animal products in sustainable production systems; and identifies factors that may impact the ability of the United States to meet demand for animal products, including the need for trained human capital, product safety and quality, and effective communication and adoption of new knowledge, information, and technologies. The agricultural sector worldwide faces numerous daunting challenges that will require innovations, new technologies, and new ways of approaching agriculture if the food, feed, and fiber needs of the global population are to be met. The recommendations of Critical Role of Animal Science Research in Food Security and Sustainability will inform a new roadmap for animal science research to meet the challenges of sustainable animal production in the 21st century.

This book was released on 2023-04-27 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: Black-tailed and mule deer represent one of the largest distributions of mammals in North America and are symbols of the wide-open American West. Each chapter in this book was authored by the world’s leading experts on that topic. Both editors, James R. Heffelfinger and Paul R. Krausman, are widely published in the popular and scientific press and recipients of the O. C. Wallmo Award, given every two years to a leading black-tailed and mule deer expert who has made significant contributions to the conservation of this species. In addition, Heffelfinger has chaired the Mule Deer Working Group sponsored by the Western Association of Fish and Wildlife Agencies for more than 15 years. This working group consists of the leading black-tailed and mule deer experts from each of 24 states, provinces, and territories in western North America, putting them at the forefront of all conservation and much of the research on this species. The book represents all current knowledge available on these deer, including how changing conditions such as fires, habitat alteration and loss, disease, climate change, socio-economic forces, energy development, and other aspects are influencing their distribution and abundance now and into the future. It takes a completely fresh look at all chapter topics. The revisions of distribution, taxonomy, evolution, behavior, and new and exciting work being done in deer nutrition, migration and movements, diseases, predation, and human dimensions are all assembled in this volume. This book will instantly become the foundation for the latest information and management strategies to be implemented on the ground by practitioners and to inform the public. Although this book is about deer, the topics discussed influence most terrestrial wildlife worldwide, and the basic concepts in many of the chapters are applicable to other species.

Book excerpt: Although traditionally defined as areas where natural vegetation is exploited for grazing by domestic and native herbivores, rangelands are used by many different people, for a host of purposes. As well as livestock products, rangelands provide fuels, minerals and water and are used for ecotourism, recreation, nature conservation and as carbon sinks. More than half of the earth's land surface is rangeland and millions of people, both within and outside the rangelands, depend on them. This book addresses the important issues confronting the rangelands and presents new concepts and approaches for the management of rangeland resources. It is relevant to the people who live in or depend on the rangelands, and to the institutions and organisations that support them.
