Available in PDF, EPUB and Kindle. Book excerpt: Running waters are enormously diverse, ranging from torrential mountain brooks, to large lowland rivers, to great river systems whose basins occupy subcontinents. While this diversity makes river ecosystems seem overwhelmingly complex, a central theme of this volume is that the processes acting in running waters are general, although the settings are often unique. The past two decades have seen major advances in our knowledge of the ecology of streams and rivers. New paradigms have emerged, such as the river continuum and nutrient spiraling. Community ecologists have made impressive advances in documenting the occurrence of species interactions. The importance of physical processes in rivers has attracted increased attention, particularly the areas of hydrology and geomorphology, and the inter-relationships between physical and biological factors have become better understood. And as is true for every area of ecology during the closing years of the twentieth century it has become apparent that the study of streams and rivers cannot be carried out by excluding the role of human activities, nor can we ignore the urgency of the need for conservation. These developments are brought together in Stream Ecology: Structure and function of running waters, designed to serve as a text for advanced undergraduate and graduate students, and as a reference book for specialists in stream ecology and related fields.

Book Synopsis Mammals and Birds as Bioindicators of Trace Element Contaminations in Terrestrial Environments by : Elżbieta Kalisińska
Download or read book Mammals and Birds as Bioindicators of Trace Element Contaminations in Terrestrial Environments written by Elżbieta Kalisińska and published by Springer. This book was released on 2019-03-01 with total page 707 pages. Available in PDF, EPUB and Kindle. Book excerpt: The population explosion that began in the 1960s has been accompanied by a decrease in the quality of the natural environment, e.g. pollution of the air, water and soil with essential and toxic trace elements. Numerous poisonings of people and animals with highly toxic anthropogenic Hg and Cd in the 20th century prompted the creation of the abiotic environment, mainly in developed countries. However, the system is insufficient for long-term exposure to low concentrations of various substances that are mainly ingested through food and water. This problem could be addressed by the monitoring of sentinels – organisms that accumulate trace elements and as such reflect the rate and degree of environmental pollution. Usually these are long-lived vertebrates – herbivorous, omnivorous and carnivorous birds and mammals, especially game species. This book describes the responses of the sentinels most commonly used in ecotoxicological studies to 17 trace elements.

Book Synopsis A guide to forest–water management by : Food and Agriculture Organization of the United Nations
Download or read book A guide to forest–water management written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2021-08-24 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many people worldwide lack adequate access to clean water to meet basic needs, and many important economic activities, such as energy production and agriculture, also require water. Climate change is likely to aggravate water stress. As temperatures rise, ecosystems and the human, plant, and animal communities that depend on them will need more water to maintain their health and to thrive. Forests and trees are integral to the global water cycle and therefore vital for water security – they regulate water quantity, quality, and timing and provide protective functions against (for example) soil and coastal erosion, flooding, and avalanches. Forested watersheds provide 75 percent of our freshwater, delivering water to over half the world’s population. The purpose of A Guide to Forest–Water Management is to improve the global information base on the protective functions of forests for soil and water. It reviews emerging techniques and methodologies, provides guidance and recommendations on how to manage forests for their water ecosystem services, and offers insights into the business and economic cases for managing forests for water ecosystem services. Intact native forests and well-managed planted forests can be a relatively cheap approach to water management while generating multiple co-benefits. Water security is a significant global challenge, but this paper argues that water-centered forests can provide nature-based solutions to ensuring global water resilience.

Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

Book Synopsis Fundamentals of Hydrology by : Tim Davie
Download or read book Fundamentals of Hydrology written by Tim Davie and published by Routledge. This book was released on 2008-04-09 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to manage the world's increasingly scarce water resources we must have a sound understanding of how water moves around the planet and what influences water quality. Fundamentals of Hydrology provides an engaging and comprehensive introduction to this subject and provides real-life examples of water resource management in a changing world. The second edition of this popular book brings the text up-to-date with additional case studies and diagrams and a greater synthesis of water quality with physical hydrology. The chapters on runoff and evaporation have been updated and the final chapter on hydrology in a changing world has more material on water resource management strategies. Additionally the chapter on streamflow analysis now includes a more in-depth section on modelling runoff. The book begins with a comprehensive coverage of precipitation, evaporation, water stored in the ground and as snow and ice, and runoff. These physical hydrological processes show with respect to the fundamental knowledge about the process, its measurement and estimation and how it ties in with water quality. Following this is a section on analyzing streamflow data, including using computer models and combining hydrology and ecology for in-stream flow assessment. A chapter on water quality shows how to measure and estimate it in a variable environment and finishes with a section on pollution treatment. The final chapter brings the text together to discuss water resource management andreal-life issues that are faced by hydrologists in a constantly changing world. Fundamentals of Hydrology is a lively and accessible introduction to the study of hydrology at university level. This new edition continues to provide an understanding of hydrological processes, knowledge of the techniques used to assess water resources and an up-to-date overview of water resource management in a changing world. Throughout the text, wide-ranging examples and case studies are used to clearly explain ideas and methods. Short chapter summaries, essay questions, guides to further reading and a glossary are also included.

Book Synopsis Skeena River Fish and Their Habitat by : Allen Gottesfeld
Download or read book Skeena River Fish and Their Habitat written by Allen Gottesfeld and published by Oregon State University Press. This book was released on 2008 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: British Columbia¿s Skeena River is one of the great salmon rivers of the North Pacific. The river and its fish have supported indigenous peoples for thousands of years. More recently, the Skeena has earned world renown for its recreational fishery and magnificent wilderness setting. Yet, over the last century, fish populations have declined from overfishing, habitat alteration and, to an unknown degree, climate change. Development of mining as well as oil and gas resources may also pose threats to fish populations.This book presents the first thorough review of the salmon stocks and freshwater species of the Skeena River. Initial chapters summarize the river¿s environment, fish, and fisheries. The book then examines the physical geography, development history, indigenous use, and major salmon stocks of each of the watershed¿s sub-basins. This volume makes available for the first time¿to researchers, field biologists, fishermen and natural history enthusiasts¿both the published, and largely unpublished, literature on this productive salmon ecosystem.

Book Synopsis North Pacific Temperate Rainforests by : Gordon H. Orians
Download or read book North Pacific Temperate Rainforests written by Gordon H. Orians and published by University of Washington Press. This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The North Pacific temperate rainforest, stretching from southern Alaska to northern California, is the largest temperate rainforest on earth. This book provides a multidisciplinary overview of key issues important for the management and conservation of the northern portion of this rainforest, located in northern British Columbia and southeastern Alaska. This region encompasses thousands of islands and millions of acres of relatively pristine rainforest, providing an opportunity to compare the ecological functioning of a largely intact forest ecosystem with the highly modified ecosystems that typify most of the world's temperate zone. The book examines the basic processes that drive the dynamic behavior of such ecosystems and considers how managers can use that knowledge to sustainably manage the rainforest and balance ecosystem integrity with human use. Together, the contributors offer a broad understanding of the challenges and opportunities faced by scientists, managers, and conservationists in the northern portion of the North Pacific rainforest that will be of interest to conservation practitioners seeking to balance economic sustainability and biodiversity conservation across the globe. Gordon Orians is professor emeritus of biology at the University of Washington. John Schoen is a senior science advisor at Audubon Alaska. Other contributors include Paul Alaback, Bill Beese, Frances Biles, Todd Brinkman, Joe Cook, Lisa Crone, Dave D'Amore, Rick Edwards, Jerry Franklin, Ken Lertzman, Stephen MacDonald, Andy MacKinnon, Bruce Marcot, Joe Mehrkens, Eric Norberg, Gregory Nowacki, Dave Person, and Sari Saunders.
