Download or read book Standing between Life and Extinction written by David L. Propst and published by University of Chicago Press. This book was released on 2021-02-15 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: North American deserts—lands of little water—have long been home to a surprising diversity of aquatic life, from fish to insects and mollusks. With European settlement, however, water extraction, resource exploitation, and invasive species set many of these native aquatic species on downward spirals. In this book, conservationists dedicated to these creatures document the history of their work, the techniques and philosophies that inform it, and the challenges and opportunities of the future. A precursor to this book, Battle Against Extinction, laid out the scope of the problem and related conservation activities through the late 1980s. Since then, many nascent conservation programs have matured, and researchers have developed new technologies, improved and refined methods, and greatly expanded our knowledge of the myriad influences on the ecology and dynamics of these species. Standing between Life and Extinction brings the story up to date. While the future for some species is more secure than thirty years ago, others are less fortunate. Calling attention not only to iconic species like the razorback sucker, Gila trout, and Devils Hole pupfish, but also to other fishes and obscure and fascinating invertebrates inhabiting intermittent aquatic habitats, this book explores the scientific, social, and political challenges of preserving these aquatic species and their habitats amid an increasingly charged political discourse and in desert regions characterized by a growing human population and rapidly changing climate.
Download or read book Water Resources in Mexico written by Úrsula Oswald Spring and published by Springer Science & Business Media. This book was released on 2011-08-26 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water resources in Mexico are threatened by scarcity, pollution and climate change. In two decades water consumption doubled, producing water stress in dry seasons and semi-arid and arid regions. Water stress rises due to physical and economic stress. In seven parts a multidisciplinary team analyzes hydrological processes in basins and their interaction with climate, soil and biota. Competing water use in agriculture, industry and domestic needs require savings, decontamination processes and desalination to satisfy the growing demand. Water quality affects health and ecosystems. This creates conflicts and cooperation that may be enhanced by public policy, institution building and social organization.
Download or read book Mass Production of Beneficial Organisms written by Juan A. Morales-Ramos and published by Academic Press. This book was released on 2013-10-08 with total page 765 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mass Production of Beneficial Organisms: Invertebrates and Entomopathogens is an essential reference and teaching tool for researchers in developed and developing countries working to produce "natural enemies" in biological control and integrated pest management programs. As we become aware of the negative impact of pesticides in human health and on the environment, interest is rapidly increasing in developing biological pest control alternatives. Tremendous advances have been made in beneficial organism technology, such as insect predators and parasitoids, mite predators, entomopathogenic nematodes, fungi, bacteria, and viruses. However, developing techniques to mass produce these biological control agents is not enough if the cost of commercialization is prohibitive. Advancing mass production to the level of economic feasibility is critical, so these new technologies can compete in the open market. This book educates academic and industry researchers, and enables further development of mass production so new technologies can compete in the open market. It is also an excellent resource for those researching beneficial arthropod mass production and technologies for other uses, including for study and application in biotechnology and biomedical research. - Focuses on techniques for mass production of beneficial organisms and methods of evaluation and quality assessment - Organizes and presents the most advanced and current knowledge on methods to mass produce beneficial organisms in response to the increased global demand for alternatives to chemical pesticides for biological control producers - Includes a team of highly respected editors and authors with broad expertise in these areas

Download or read book Hindu Kush Himalaya Watersheds Downhill Landscape Ecology and Conservation Perspectives written by Ganga Ram Regmi and published by Springer Nature. This book was released on 2020-05-04 with total page 890 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the myriad components of the Hindu Kush-Himalaya (HKH) region. The contributors elaborate on challenges, failures, and successes in efforts to conserve the HKH, its indigenous plants and animals, and the watershed that runs from the very roof of the planet via world-rivers to marine estuaries, supporting a human population of some two billion people. Readers will learn how the landforms, animal species and humans of this globally fascinating region are connected, and understand why runoff from snow and ice in the world’s tallest mountains is vital to inhabitants far downstream. The book comprises forty-five chapters organized in five parts. The first section, Landscapes, introduces the mountainous watersheds of the HKH, its weather systems, forests, and the 18 major rivers whose headwaters are here. The second part explores concepts, cultures, and religions, including ethnobiology and indigenous regimes, two thousand years of religious tradition, and the history of scientific and research expeditions. Part Three discusses policy, wildlife conservation management, habitat and biodiversity data, as well as the interaction of animals and humans. The fourth part examines the consequences of development and globalization, from hydrodams, to roads and railroads, to poaching and illegal wildlife trade. This section includes studies of animal species including river dolphins, woodpeckers and hornbills, langurs, snow leopards and more. The concluding section offers perspectives and templates for conservation, sustainability and stability in the HKH, including citizen-science projects and a future challenged by climate change, growing human population, and global conservation decay. A large assemblage of field and landscape photos, combined with eye-witness accounts, presents a 50-year local and wider perspective on the HKH. Also included are advanced digital topics: data sharing, open access, metadata, web portal databases, geographic information systems (GIS) software and machine learning, and data mining concepts all relevant to a modern scientific understanding and sustainable management of the Hindu Kush-Himalaya region. This work is written for scholars, landscape ecologists, naturalists and researchers alike, and it can be especially well-suited for those readers who want to learn in a more holistic fashion about the latest conservation issues.
Download or read book Key Topics in Conservation Biology 2 written by David W. Macdonald and published by John Wiley & Sons. This book was released on 2013-04-22 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following the much acclaimed success of the first volume of Key Topics in Conservation Biology, this entirely new second volume addresses an innovative array of key topics in contemporary conservation biology. Written by an internationally renowned team of authors, Key Topics in Conservation Biology 2 adds to the still topical foundations laid in the first volume (published in 2007) by exploring a further 25 cutting-edge issues in modern biodiversity conservation, including controversial subjects such as setting conservation priorities, balancing the focus on species and ecosystems, and financial mechanisms to value biodiversity and pay for its conservation. Other chapters, setting the framework for conservation, address the sociology and philosophy of peoples’ relation with Nature and its impact on health, and such challenging practical issues as wildlife trade and conflict between people and carnivores. As a new development, this second volume of Key Topics includes chapters on major ecosystems, such as forests, islands and both fresh and marine waters, along with case studies of the conservation of major taxa: plants, butterflies, birds and mammals. A further selection of topics consider how to safeguard the future through monitoring, reserve planning, corridors and connectivity, together with approaches to reintroduction and re-wilding, along with managing wildlife disease. A final chapter, by the editors, synthesises thinking on the relationship between biodiversity conservation and human development. Each topic is explored by a team of top international experts, assembled to bring their own cross-cutting knowledge to a penetrating synthesis of the issues from both theoretical and practical perspectives. The interdisciplinary nature of biodiversity conservation is reflected throughout the book. Each essay examines the fundamental principles of the topic, the methodologies involved and, crucially, the human dimension. In this way, Key Topics in Conservation Biology 2, like its sister volume, Key Topics in Conservation Biology, embraces issues from cutting-edge ecological science to policy, environmental economics, governance, ethics, and the practical issues of implementation. Key Topics in Conservation Biology 2 will, like its sister volume, be a valuable resource in universities and colleges, government departments, and conservation agencies. It is aimed particularly at senior undergraduate and graduate students in conservation biology and wildlife management and wider ecological and environmental subjects, and those taking Masters degrees in any field relevant to conservation and the environment. Conservation practitioners, policy-makers, and the wider general public eager to understand more about important environmental issues will also find this book invaluable.

Download or read book Trout and Char of the World written by Jeffrey L. Kershner and published by . This book was released on 2019 with total page 831 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first comprehensive look at the taxonomy, life history, and conservation status of the world's trout and char. These are fascinating and beautiful fish that rate high for the angler as well as for tourist and recreational economies. Trout and char also play key roles in the ecology of many lake and river systems around the world. Trout and char are abundant in many regions, but most native species are on the decline. Some are classified as vulnerable, threatened, or endangered. Because of their widespread stocking in regions where they are not native, some trout and char also are the cause for threats to other native species. Loss of habitat, an expanding human population, and rapid climate change are challenging their future as streams warm and waters become more variable in their flows. This book examines trout and char from all these perspectives. Early chapters explore the unique diversity and life history aspects of trout and char and provide information on the taxonomy and systematics while also detailing some of unique life histories. New information is presented about species diversity and distributions by country. Summary chapters explore significant conservation and management challenges of broad interest to scientists, resource managers, anglers, and interested public. Trout and Char of the World end s with a series of essays exploring the future of trout and char over the next 50 years. Trout and Char of the World will be a primary resource for trout and char biologists, conservationists, and anglers in the many countries where trout and char are native or have been introduced, and a resource for anyone interested in learning more about the diversity and distribution of trout and char worldwide.--
