Download or read book Wetlands written by Committee on Characterization of Wetlands and published by National Academies Press. This book was released on 1995-09-20 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Wetlands" has become a hot word in the current environmental debate. But what does it signify? In 1991, proposed changes in the legal definities of wetlands stirred controversy and focused attention on the scientific and economic aspects of their management. This volume explores how to define wetlands. The committee--whose members were drawn from academia, government, business, and the environmental community--builds a rational, scientific basis for delineating wetlands in the landscape and offers recommendations for further action. Wetlands also discusses the diverse hydrological and ecological functions of wetlands, and makes recommendations concerning so-called controversial areas such as permafrost wetlands, riparian ecosystems, irregularly flooded sites, and agricultural wetlands. It presents criteria for identifying wetlands and explores the problems of applying those criteria when there are seasonal changes in water levels. This comprehensive and practical volume will be of interest to environmental scientists and advocates, hydrologists, policymakers, regulators, faculty, researchers, and students of environmental studies.

Download or read book Methods in Stream Ecology written by F. Richard Hauer and published by Academic Press. This book was released on 2011-04-27 with total page 894 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods in Stream Ecology, Second Edition, provides a complete series of field and laboratory protocols in stream ecology that are ideal for teaching or conducting research. This updated edition reflects recent advances in the technology associated with ecological assessment of streams, including remote sensing. In addition, the relationship between stream flow and alluviation has been added, and a new chapter on riparian zones is also included. The book features exercises in each chapter; detailed instructions, illustrations, formulae, and data sheets for in-field research for students; and taxanomic keys to common stream invertebrates and algae. With a student-friendly price, this book is key for all students and researchers in stream and freshwater ecology, freshwater biology, marine ecology, and river ecology. This text is also supportive as a supplementary text for courses in watershed ecology/science, hydrology, fluvial geomorphology, and landscape ecology. - Exercises in each chapter - Detailed instructions, illustrations, formulae, and data sheets for in-field research for students - Taxanomic keys to common stream invertebrates and algae - Link from Chapter 22: FISH COMMUNITY COMPOSITION to an interactive program for assessing and modeling fish numbers

Download or read book Creating the National Park Service written by Horace M. Albright and published by University of Oklahoma Press. This book was released on 1999 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two men played a crucial role in the creation and early history of the National Park Service: Stephen T. Mather, a public relations genius of sweeping vision, and Horace M. Albright, an able lawyer and administrator who helped transform that vision into reality. In Creating the National Park Service, Albright and his daughter, Marian Albright Schenck, reveal the previously untold story of the critical "missing years" in the history of the service. During this period, 1917 and 1918, Mather's problems with manic depression were kept hidden from public view, and Albright, his able and devoted assistant, served as acting director and assumed Mather's responsibilities. Albright played a decisive part in the passage of the National Park Service Organic Act of 1916; the formulation of principles and policies for management of the parks; the defense of the parks against exploitation by ranchers, lumber companies, and mining interests during World War I; and other issues crucial to the future of the fledgling park system. This authoritative behind-the-scenes history sheds light on the early days of the most popular of all federal agencies while painting a vivid picture of American life in the early twentieth century.

Download or read book Spills of Diluted Bitumen from Pipelines written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-03-22 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diluted bitumen has been transported by pipeline in the United States for more than 40 years, with the amount increasing recently as a result of improved extraction technologies and resulting increases in production and exportation of Canadian diluted bitumen. The increased importation of Canadian diluted bitumen to the United States has strained the existing pipeline capacity and contributed to the expansion of pipeline mileage over the past 5 years. Although rising North American crude oil production has resulted in greater transport of crude oil by rail or tanker, oil pipelines continue to deliver the vast majority of crude oil supplies to U.S. refineries. Spills of Diluted Bitumen from Pipelines examines the current state of knowledge and identifies the relevant properties and characteristics of the transport, fate, and effects of diluted bitumen and commonly transported crude oils when spilled in the environment. This report assesses whether the differences between properties of diluted bitumen and those of other commonly transported crude oils warrant modifications to the regulations governing spill response plans and cleanup. Given the nature of pipeline operations, response planning, and the oil industry, the recommendations outlined in this study are broadly applicable to other modes of transportation as well.

Book excerpt: Freshwater Ecology, Second Edition, is a broad, up-to-date treatment of everything from the basic chemical and physical properties of water to advanced unifying concepts of the community ecology and ecosystem relationships as found in continental waters.With 40% new and expanded coverage, this text covers applied and basic aspects of limnology, now with more emphasis on wetlands and reservoirs than in the previous edition. It features 80 new and updated figures, including a section of color plates, and 500 new and updated references. The authors take a synthetic approach to ecological problems, teaching students how to handle the challenges faced by contemporary aquatic scientists.This text is designed for undergraduate students taking courses in Freshwater Ecology and Limnology; and introductory graduate students taking courses in Freshwater Ecology and Limnology. - Expanded revision of Dodds' successful text. - New boxed sections provide more advanced material within the introductory, modular format of the first edition. - Basic scientific concepts and environmental applications featured throughout. - Added coverage of climate change, ecosystem function, hypertrophic habitats and secondary production. - Expanded coverage of physical limnology, groundwater and wetland habitats. - Expanded coverage of the toxic effects of pharmaceuticals and endocrine disrupters as freshwater pollutants - More on aquatic invertebrates, with more images and pictures of a broader range of organisms - Expanded coverage of the functional roles of filterer feeding, scraping, and shredding organisms, and a new section on omnivores. - Expanded appendix on standard statistical techniques. - Supporting website with figures and tables - http://www.elsevierdirect.com/companion.jsp?ISBN=9780123747242
