The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.
Addresses the issue of modern corporate power, exposing the harmful effects gobalization is having not only on economics, but also on politics, society and the environment
The 1985 Research Conference on Fire Ants and Leaf-Cutting Ants covered the most recent developments in research and control of these insect pests of the New World tropical and subtropical zones, the southern United States, South and Central America, and the Caribbean Islands. This volume contains chapters that discuss the history and economics, biology and ecology, behavior, pheromones and other semiochemicals, physiology, and biochemistry of fire ants and leaf-cutting ants, as well as current and future control strategies. The information provided illustrates past and present agricultural and medical problems associated with these pest ants; however, it also brings out the point that they ...

Winner of the 2010 Bancroft Prize and finalist for the 2009 Los Angeles Times Book Prize in Biography: The definitive biography of a heroic chronicler of America's Depression and one of the twentieth century's greatest photographers. We all know Dorothea Lange's iconic photos—the Migrant Mother holding her child, the shoeless children of the Dust Bowl—but now renowned American historian Linda Gordon brings them to three-dimensional life in this groundbreaking exploration of Lange's transformation into a documentarist. Using Lange's life to anchor a moving social history of twentieth-century America, Gordon masterfully re-creates bohemian San Francisco, the Depression, and the Japanese-American internment camps. Accompanied by more than one hundred images—many of them previously unseen and some formerly suppressed—Gordon has written a sparkling, fast-moving story that testifies to her status as one of the most gifted historians of our time. Finalist for the Los Angeles Times Book Prize; a New York Times Notable Book; New Yorker's A Year's Reading; and San Francisco Chronicle Best Book.
The chapters of Studies on Periodontal Disease comprise four parts. Part 1 provides basic sciences from the general to the particular. The findings of cell culture and animal models supply the mechanism between periodontal disease and oxidative stress. In part 2, human clinical studies are mainly addressed. The effects of periodontal therapy on circulating oxidative stress are also discussed. The relationships between periodontal disease and systemic diseases are examined in part 3. The involvement of oxidative stress and inflammation are discussed through in vivo and in vitro study results. Part 4 discusses future strategies, including the effects of antioxidants and nutrition on periodontal disease. This thorough examination of the relationship between oxidative stress and periodontal disease is essential reading for researchers in oxidative stress and periodontal clinicians, alike.
This book explores the opportunities and challenges of the sharing economy and innovative transportation technologies with regard to urban mobility. Written by government experts, social scientists, technologists and city planners from North America, Europe and Australia, the papers in this book address the impacts of demographic, societal and economic trends and the fundamental changes arising from the increasing automation and connectivity of vehicles, smart communication technologies, multimodal transit services, and urban design. The book is based on the Disrupting Mobility Summit held in Cambridge, MA (USA) in November 2015, organized by the City Science Initiative at MIT Media Lab, the Transportation Sustainability Research Center at the University of California at Berkeley, the LSE Cities at the London School of Economics and Politics and the Innovation Center for Mobility and Societal Change in Berlin.
