Despite nearly three decades of efforts intended to protect the nation's waters, and some success against certain forms of chemical and organic contamination, many of our nation's waterways continue to be seriously degraded. The call of the 1972 Clean Water Act -- "to restore and maintain the chemical, physical, and biological integrity of the Nation's waters" -- remains unanswered. Restoring Life in Running Waters discusses freshwater ecosystems in the United States and the need for using biology to understand their present condition. The book makes a case for using indexes that integrate measurements of many biological attributes to assess and communicate environmental health. In a unique and innovative format, the authors present 37 premises and 7 myths that explore the theory and practice of biological monitoring and the use of multimetric indexes. The book explains: why biological monitoring and assessment are needed the historical evolution of biological monitoring how and why living systems give the best signals for diagnosing environmental degradation what multimetric indexes do and why they are effective how multimetric indexes can be used and common pitfalls to avoid in using them why many criticisms of biological indexes are not valid how the principles of biological monitoring and multimetric indexes can be expanded beyond aquatic systems to other environments how information from indexes can be integrated into the regulatory and policy framework Restoring Life in Running Waters provides practical and effective tools for managers and scientists seeking to understand the impact of human activities on natural systems and to determine proper action to remedy problems. It is an essential handbook for conservation biologists; agency personnel at all levels, including technical staff, policymakers, and program managers; and for anyone working to protect and restore the health of the nation's waters.

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.

Download and read online ebook Assessing the Ecological Integrity of Running Waters write by M. Jungwirth. This book was released on 2012-12-06. Assessing the Ecological Integrity of Running Waters available in PDF, EPUB and Kindle. The assessment of the ecological integrity of running waters is a prerequisite to an understanding of the effects of human alterations. The evaluation of degradation processes provides key information on how to avoid further negative impacts. The success of future conservation, mitigation and restoration activities will rely on sound assessment methodologies and their ecological relevance and applicability. Assessment methodologies are therefore an integral part of sustainable river management. This book synthesizes and discusses state-of-the-art experiences in assessment methodologies. Including the latest knowledge on structures, processes and functions of running waters as a fundamental basis for developing adequate assessment methods, the book focuses on method development, application, and in particular on integrated assessment methods. This book is directed at scientists and managers with the aim of more effective preservation, restoration and maintenance of the ecological integrity of running water ecosystems.
