Download or read book Bioenergetics Of Wild Herbivores written by Robert J. Hudson and published by CRC Press. This book was released on 2018-01-18 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioenergetics is an emerging discipline which offers a more profound understanding of the ecology, behaviour, and evolution of wild herbivores. Increasingly, bioenergetic principles have been applied in management since they provide insight into population dynamics and are relevant to manipulation of habitats and assessment of the impacts of resource development. Growing interest in the agricultural potential of wild herbivores has provided further impetus. In spite of this promise, there are few comprehensive syntheses of the concept and its application to wild herbivores. This volume attempts to fill this need. This book provides a great amount of detail but its expressive aim is to lead us to the whole animal, to a herd, to population as integral parts of an ecological entity which in turn is the result of evolutionary forces.The concept of this book promises the realization of an overdue change in the approach to bioenergetics, to nutrition and husbandry, and thus to the management of wild herbivores: the final emancipation from rules and views based primarily on domesticated herbivores or on experimental animals held under unnatural conditions, necessarily impending them behaviourally, physically, and psychically.

Available in PDF, EPUB and Kindle. Book excerpt: This volume investigates how large herbivores not only influence the structure and distribution of the vegetation, but also affect nutrient flows and the responses of associated fauna. The mechanisms and processes underlying the herbivores' behavior, distribution, movement and direct impact on the vegetation are discussed in detail. It is shown that an understanding of plant/animal interactions can inform the management of large herbivores to integrate production and conservation in terrestrial systems.

Download or read book The Ecosystem Concept in Natural Resource Management written by George Van Dyne and published by Elsevier. This book was released on 2012-12-02 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ecosystem Concept in Natural Resource Management focuses on the ecosystem concept and its application to natural resource management. It presents examples of research concepts on natural resource phenomena and discusses ecosystem implications for natural resource management. It also covers range, forest, watershed, fisheries, and wildlife resource science and management. Organized into four sections encompassing 10 chapters, this volume begins with an overview of the meaning, origin, and importance of ecosystem concepts before proceeding with a discussion of field research projects that address the ecosystem concept and the ways in which the concept has been or can be useful in both research and management in natural resource sciences. More specifically, it explores major developments in the field of ecology in relation to natural resource management, with examples from forest ecology. It also introduces the reader to procedures for studying grassland ecosystems, the watershed-ecosystem concept and studies of nutrient cycles, ecosystem concepts in forestry, ecosystem models in watershed management, and the implementation of the ecosystem concept in training in the natural resource sciences. This book is a valuable resource for scientists, educators, technicians, and training resource managers, as well as students in resource management courses.
Download or read book The Gnu s World written by Richard D. Estes and published by Univ of California Press. This book was released on 2014-04-12 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first scholarly book on the antelope that dominates the savanna ecosystems of eastern and southern Africa. It presents a synthesis of research conducted over a span of fifty years, mainly on the wildebeest in the Ngorongoro and Serengeti ecosystems, where eighty percent of the world’s wildebeest population lives. Wildebeest and other grazing mammals drive the ecology and evolution of the savanna ecosystem. Richard D. Estes describes this process and also details the wildebeest’s life history, focusing on its social organization and unique reproductive system, which are adapted to the animal’s epic annual migrations. He also examines conservation issues that affect wildebeest, including range-wide population declines.
Download or read book Changing the Global Environment written by Daniel B. Botkin and published by Elsevier. This book was released on 2013-10-22 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: Changing the Global Environment: Perspectives on Human Involvement focuses on the extent of global environmental changes and the extent to which technology can be employed to improve the global environment. This book is divided into three sections. Section I sets forth a broad perspective on specific conceptual issues of concern such as the sustainable use of the global ocean; deforestation and extinction of species; large-scale alteration of biological productivity due to transported pollutants; and soil degradation and conversion of tropical rainforests. The second section discusses technologies of remote sensing, computer-based data systems, and advanced chemical analytical techniques. The interactions among social, environmental, and economic goals and the role that technological advances might play in attaining these goals are deliberated in Section III. This publication is valuable to environmentalists and students interested in how technologies can change man's perception of the environment.
Download or read book Extinctions in Near Time written by Ross D.E. MacPhee and published by Springer Science & Business Media. This book was released on 2013-11-09 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Near time" -an interval that spans the last 100,000 years or so of earth history-qualifies as a remarkable period for many reasons. From an anthropocentric point of view, the out standing feature of near time is the fact that the evolution, cultural diversification, and glob al spread of Homo sapiens have all occurred within it. From a wider biological perspective, however, the hallmark of near time is better conceived of as being one of enduring, repeat ed loss. The point is important. Despite the sense of uniqueness implicit in phrases like "the biodiversity crisis," meant to convey the notion that the present bout of extinctions is by far the worst endured in recent times, substantial losses have occurred throughout near time. In the majority of cases, these losses occurred when, and only when, people began to ex pand across areas that had never before experienced their presence. Although the explana tion for these correlations in time and space may seem obvious, it is one thing to rhetori cally observe that there is a connection between humans and recent extinctions, and quite another to demonstrate it scientifically. How should this be done? Traditionally, the study of past extinctions has fallen largely to researchers steeped in such disciplines as paleontology, systematics, and paleoecology. The evaluation of future losses, by contrast, has lain almost exclusively within the domain of conservation biolo gists. Now, more than ever, there is opportunity for overlap and sharing of information.
Download or read book Asdell s Patterns of Mammalian Reproduction written by Virginia Douglass Hayssen and published by Cornell University Press. This book was released on 1993 with total page 1036 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the appearance of the second edition of Sydney A. Asdell's widely used Patterns of Mammalian Reproduction in 1964, the field of reproductive physiology has expanded dramatically. Accordingly, this revision adopts a different structure from previous editions, substituting empirical delineations for physiological interpretations. With the emphases now on a presentation of the published facts of mammalian reproduction, it provides a thorough compilation of what is known about the basic reproductive biology of each of the 4300 mammalian species.To gather information, the authors examined more than 20,000 publications, dating up to 1992. They used primary sources as much as possible, supplementing them with English translations of Russian, Finnish, Chinese, and Japanese journals. The data are presented in taxonomic order. Each familial account summarizes the pattern of reproduction for the family and provides lists of citations arranged by topic of the literature on the endocrinology, reproductive anatomy, and reproductive physiology of the family. Following each account is a tabular listing of species-specific data for neonatal mass and size, weaning mass and size, litter size, age at sexual maturity, estrous cycle length, gestation length, lactation length, number of litters per year, and seasonality of reproduction. For each of these reproductive variables, the range of data gleaned from the literature is given, together with the source of each value listed.Virginia Hayssen is Assistant Professor of Biology at Smith College. Ari Van Tienhoven is Professor of Animal Physiology, Emeritus, at Cornell University. Ans Van Tienhoven assisted in the compilation of data for the book.
Download or read book The Ecology of Large Mammals in Central Yellowstone written by Robert A. Garrott and published by Academic Press. This book was released on 2008-11-25 with total page 712 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an authoritative work on the ecology of some of America's most iconic large mammals in a natural environment - and of the interplay between climate, landscape, and animals in the interior of the world's first and most famous national park.Central Yellowstone includes the range of one of the largest migratory populations of bison in North America as well as a unique elk herd that remains in the park year round. These populations live in a varied landscape with seasonal and often extreme patterns of climate and food abundance. The reintroduction of wolves into the park a decade ago resulted in scientific and public controversy about the effect of large predators on their prey, a debate closely examined in the book. Introductory chapters describe the geography, geology and vegetation of the ecosystem. The elk and bison are then introduced and their population ecology described both pre- and post– wolf introduction, enabling valuable insights into the demographic and behavioral consequences for their ungulate prey. Subsequent chapters describe the wildlife-human interactions and show how scientific research can inform the debate and policy issues surrounding winter recreation in Yellowstone. The book closes with a discussion of how this ecological knowledge can be used to educate the public, both about Yellowstone itself and about science, ecology and the environment in general. Yellowstone National Park exemplifies some of the currently most hotly debated and high-profile ecological, wildlife management, and environmental policy issues and this book will have broad appeal not only to academic ecologists, but also to natural resource students, managers, biologists, policy makers, administrators and the general public. - Unrivalled descriptions of ecological processes in a world famous ecosystem, based on information from 16 years of painstaking field work and collaborations among 66 scientists and technical experts and 15 graduate studies - Detailed studies of two charismatic North American herbivore species – elk and bison - Description of the restoration of wolves into central Yellowstone and their ecological interactions with their elk and bison prey - Illustrated with numerous evocative colour photographs and stunning maps

Download or read book Foundations of Environmental Sustainability written by Larry Rockwood and published by Oxford University Press. This book was released on 2008-06-04 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews and analyzes the period (roughly from the 1950s to the present) when the "environment" became an issue as important as economic growth, or war and peace; to assess the current situation, and begin planning for the challenges that lie ahead. Most people are aware of both the environmental destruction taking place around the world and of the specter of climate change. The devastation of New Orleans by hurricane Katrina illustrates the potential for disaster when climate change is combined with the mismanaged environmental policy. How did we get to this point? What has been done and what can be done to avoid future environmental disasters? Thirty-two contributing chapter authors (among them, one of the principal drafters of the National Environmental Policy Act, Chief of the African Environment Division and the World Bank, Vice President of the Center for Conservation Innovation at the World Wildlife Fund, President of the Zoological Society of London, former President of the Ecological Society of America) use their unique, authoritative perspective to review the evolution of environmental science and policy in the past half century. Each author describes the evolution of environmental science and policy in the past half century and consider the challenges of the future. Although the authors of this book come from various fields, they have followed paths that have generally converged on the concept of sustainability. This book attempts to define what sustainability is, how we can achieve it, and what the prospects for sustainability in the future are.
Download or read book Bonebeds written by Raymond R. Rogers and published by University of Chicago Press. This book was released on 2010-02-15 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vertebrate fossil record extends back more than 500 million years, and bonebeds—localized concentrations of the skeletal remains of vertebrate animals—help unlock the secrets of this long history. Often spectacularly preserved, bonebeds—both modern and ancient—can reveal more about life histories, ecological associations, and preservation patterns than any single skeleton or bone. For this reason, bonebeds are frequently studied by paleobiologists, geologists, and archeologists seeking to piece together the vertebrate record. Thirteen respected researchers combine their experiences in Bonebeds, providing readers with workable definitions, theoretical frameworks, and a compendium of modern techniques in bonebed data collection and analysis. By addressing the historical, theoretical, and practical aspects of bonebed research, this edited volume—the first of its kind—provides the background and methods that students and professionals need to explore and understand these fantastic records of ancient life and death.
