River food chains
\"This book explores the food chains and webs that exist in river habitats. It equips readers with crucial vocabulary, using examples from that habitat to explain the roles of producers, consumers and decomposers, and illustrates how living things depend upon each other. Readers learn how fragile food chains can be, how they can be broken, and what we can do to prevent this.\"-- Provided by publisher.

River conservation and management
This book is intended for those with an academic, scientific and practical interest in river conservation and management. It provides an overview of how changes in legislation, policies, institutional responsibilities, science, technology, practical techniques and public perception have influenced how rivers have been managed over the past 20 years and the challenges that lie ahead during the next 20 years. The book is based on the international conference River Conservation and Management:20 Years On held at York. Thirty-one chapters, with contributions from North and South America, Europe, Asia and Australasia provide a wide-ranging perspective on this complex but profoundly important subject. Following an introduction that chronicles the most important contextual changes, the book is organized into four broad topics: * Catchment management, ecosystem integrity and the threats to river ecosystems – this covers progress on understanding and addressing the pressures affecting rivers, many of which will be amplified by climate change and increasing human demands for water; * Methods and approaches – illustrating some recent techniques that have been developed to assess condition and conservation status across different types of river; * Recovery and rehabilitation – providing an insight into the principles, practice, public involvement and institutional networks that support and make improvements to modified river reaches; * Integrating nature conservation into wider river management –demonstrating the importance of integrated planning, involvement of local communities and the use of adaptive management in achieving multiple environmental and economic benefits along rivers used for different purposes. The final chapter discusses the challenges faced in dealing with an uncertain future. More than 1200 different references and numerous web-site citations provide the reader with an invaluable source of knowledge on the subject area.

Hydrology, ecology, and fishes of the Klamath River Basin
The Klamath River basin, which spans parts of southern Oregon and northern California, has been the focus of a prominent conflict over competing uses for water. Management actions to protect threatened and endangered fish species in the basin have left less water available for irrigation in dry years and heightened tensions among farmers and other stakeholders including commercial fishermen, Native Americans, conservationists, hunters, anglers, and hydropower producers. This National Research Council book assesses two recent studies that evaluate various aspects of flows in the Klamath basin: (1) the Instream Flow Phase II study (IFS), conducted by Utah State University, and (2) the Natural Flow of the Upper Klamath Basin study (NFS), conducted by the U.S. Bureau of Reclamation (USBR). The book concludes that both studies offer important new information but do not provide enough information for detailed management of flows in the Klamath River, and it offers many suggestions for improving the studies. The report recommends that a comprehensive analysis of the many individual studies of the Klamath river basin be conducted so that a big picture perspective of the entire basin and research and management needs can emerge.

The boatman : Henry David Thoreau's river years
The Boatman gives readers a Thoreau for the Anthropocene epoch. As a backyard naturalist and river enthusiast, Thoreau was keenly aware of the way humans had altered the waterways and meadows of his beloved Concord River Valley. And he recognized that he himself--a land surveyor by trade--was as complicit in these transformations as the bankers, lawyers, builders, landowners, and elected officials who were his clients. Robert Thorson tells a compelling story of intellectual growth, as Thoreau moved from anger, to lament, to acceptance of the way humans had changed the river he cherished more than Walden Pond.
Book
River republic
Daniel McCool not only chronicles the history of water development agencies in America and the way in which special interests have abused rather than preserved the country's rivers, he also narrates the second, brighter act in this ongoing story: the surging, grassroots movement to bring these rivers back to life and ensure they remain pristine for future generations. The culmination of ten years of research and observation, McCool's book confirms the surprising news that America's rivers are indeed returning to a healthier, free-flowing condition. The politics of river restoration demonstrates how strong grassroots movements can challenge entrenched powers and win. Through passion and dedication, ordinary people are reclaiming the American landscape, forming a \"river republic\" of concerned citizens from all backgrounds and sectors of society. As McCool shows, the history, culture, and fate of America is tied to its rivers, and their restoration is a microcosm mirroring American beliefs, livelihoods, and an increasing awareness of what two hundred years of environmental degradation can do. McCool profiles the individuals he calls \"instigators,\" who initiated the fight for these waterways and, despite enormous odds, have succeeded in the near-impossible task of challenging and changing the status quo. Part I of the volume recounts the history of America's relationship to its rivers; part II describes how and why Americans \"parted\" them out, destroying their essence and diminishing their value; and part III shows how society can live in harmony with its waterways while restoring their well-being—and, by extension, the well-being of those who depend on them.

Transborder Governance of Forests, Rivers and Seas
Natural resources often stretch across borders that separate modern nation states. This can create conflict and limit opportunities for regulated consumption of their goods and services, but also provide opportunities for joint multinational efforts that exceed single country capabilities.
This book illustrates the diversity of transborder natural resources, the pressures that they experience or the opportunities that exist for multinational regulatory regimes, monitoring and enforcement. It presents ten case studies of transborder natural resources that are of interest to two or more neighboring countries, and that are subject to, or in need of bilateral or multinational coordinated management. The case studies include the exploitation of specific marine resources in international waters, rivers that travel through several countries and contiguous tropical forests across national borders, and where commodities, nature conservation or even territorial integrity are at stake. They are drawn from across the globe, including flood management in Western Europe, tropical forests in the Western Amazon, hydropower development in the Mekong region of South-east Asia, forest conservation in Central Africa and marine resource and fisheries exploitation in the waters of Japan, South-east Asia and Australia. Together the chapters provide a review of a wide range of transborder natural resource examples, and the diverse regulatory regimes that need to be devised to achieve successful management. An introductory chapter provides a conceptual and theoretical underpinning that can guide future research efforts on similar cases and a concluding chapter draws major conclusions and implications for related concepts and theories.

Book
Disconnected rivers
This important and accessible book surveys the history and present condition of river systems across the United States, showing how human activities have impoverished our rivers and impaired the connections between river worlds and other ecosystems.Ellen Wohl begins by introducing the basic physical, chemical, and biological processes operating in rivers. She then addresses changes in rivers resulting from settlement and expansion, describes the growth of federal involvement in managing rivers, and examines the recent efforts to rehabilitate and conserve river ecosystems. In each chapter she focuses on a specific regional case study and describes what happens to a particular river organism-a bird, North America's largest salamander, the paddlefish, and the American alligator-when people interfere with natural processes.
