Book Description
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.

Book Description
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 Description
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.

Book Description
This book provides the focal point of the European Water Framework Directive. offering insight into principles and methodologies of river assessment, covering the whole range from the definition of river typologies to specific problems such as the most appropriate taxonomic resolution and software applications. The text focuses on benthic macroinvertebrates, the taxonomic group most frequently used in bioassessment.

Book Description
Gebara's succinct yet moving statement of her principles of ecofeminism shows how intertwined are the tarnished environment around her and the poverty that afflicts her neighbors. From her experiences with the Brazilian poor women's movement she develops a gritty urban ecofeminism and indeed articulates a whole worldview. She shows how the connections between Western thought, partriachal Christianity, and environmental destruction necessitate personal conversion to "an new relationship with the earth and with the entire cosmos."

Book Description
Like Letters in Running Water explores ways in which fiction (prose, drama, poetry, myth, fairytale) yields transformative insights for educational theory and practice. Through a series of intensely original, powerful essays drawing on curriculum theory, literary analysis, psychology, and feminist theory and practice, Doll seeks to confront a commonly held bias that reading literary fictions is "mere" entertainment (not a learning experience). She suggests that fiction has immense teaching power because it connects readers with their alliances within themselves and this connection attends to social, outer issues addressed by traditional pedagogies with greater, deeper awareness. Her elaboration in this book of the concept of currere--the lived experience of curriculum--through literature, drama, and myth is a major contribution to the field of curriculum theory.

Book Description
Finalist for the National Book Award An intimate reckoning with aquifer depletion in America's heartland The Ogallala aquifer has nourished life on the American Great Plains for millennia. But less than a century of unsustainable irrigation farming has taxed much of the aquifer beyond repair. The imminent depletion of the Ogallala and other aquifers around the world is a defining planetary crisis of our times. Running Out offers a uniquely personal account of aquifer depletion and the deeper layers through which it gains meaning and force. Anthropologist Lucas Bessire journeyed back to western Kansas, where five generations of his family lived as irrigation farmers and ranchers, to try to make sense of this vital resource and its loss. His search for water across the drying High Plains brings the reader face to face with the stark realities of industrial agriculture, eroding democratic norms, and surreal interpretations of a looming disaster. Yet the destination is far from predictable, as the book seeks to move beyond the words and genres through which destruction is often known. Instead, this journey into the morass of eradication offers a series of unexpected discoveries about what it means to inherit the troubled legacies of the past and how we can take responsibility for a more inclusive, sustainable future. An urgent and unsettling meditation on environmental change, Running Out is a revelatory account of family, complicity, loss, and what it means to find your way back home.
