Download or read book Restoration of Aquatic Ecosystems written by National Research Council and published by National Academies Press. This book was released on 1992-01-01 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

Download or read book America s National Game written by Albert G. Spalding and published by Jazzybee Verlag. This book was released on 2020-09-14 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is in great demand by baseball enthusiasts. Having been connected with every department of the game from player to magnate, Mr. Spalding has contributed a very important work to the game's history. As the invincible pitcher of the Boston Club, previous to the formation of the National League, his book of so many pages is an interesting record of events dating from the beginning of the great American pastime. It is not exactly a history of the game, but deals largely with incidents during the author's career, who was a player in the late 1860s and early 1870s, and helped organize the National League in 1876. One chapter, devoted to sundry topics, gives an account of the sale of the immortal "King Kelly," the original "$10,000 beauty," by Chicago to the Boston Club in the late 1880s. Other Chapters are devoted to the literature of the game, quoting several instances of the baseball paragrapher's art and also specimens of the distinct poetry of the pastime, of which "Casey at the Bat" is probably the most widely known. The Cincinnati Red Stockings Mr. Spalding gives credit as being the pioneer professional organization. It was not, however, until 1871 that professional baseball playing, as recognized today, was instituted. Mr. Spalding shows how cricket could not do for Americans. He says it is suitable for the British temperament, but not for the Yankee hustling spirit. He also tells how he worked into the game through a one-handed catch when a small boy. To lovers of baseball, whose name is legion, and whose number increases yearly, this book comprises in itself a whole library of useful information.

This book was released on 2012-12-06 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: In its statutory authority (National Science Foundation Act of 1950, as amended), the NSF is directed to both initiate and support basic scientific research. In its Ecology Program, one mode of initiating research is to en courage the development of new ideas through advisory workshops. The NSF is specifically directed to strengthen our nation's research potential. In addition, stimulating new approaches to research will continue to be prominent in the coming years as federal attention is given to increasing the innovativeness and competitiveness of the U. S. in science and engineering. A decision to initiate a workshop does not arise de novo in the Ecology Program. Rather, it emerges from panel discussions, conversations with in vestigators at meetings or on the phone, and from discussions between pro gram officers in the Division of Biotic Systems and Resources. This workshop was developed to provide advice to the NSF and the lim nological community. Some NSF perceptions on future funding for ecolog ical research on lake communities are presented here. Researchers often mentioned a paucity of innovative lake ecology at the community level. This perception was accompanied by a certain frustration since lakes probably have the best empirical data base of any natural environment and should continue to lead in the development of ecological concepts. Members of NSF advisory panels sometimes expressed similar concerns during consid eration of proposals for lake research.
Download or read book Ecotoxicology Problems and Approaches written by Simon A. Levin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecotoxicology is the science that seeks to predict the impacts of chemi cals upon ecosystems. This involves describing and predicting ecological changes ensuing from a variety of human activities that involve release of xenobiotic and other chemicals to the environment. A fundamental principle of ecotoxicology is embodied in the notion of change. Ecosystems themselves are constantly changing due to natural processes, and it is a challenge to distinguish the effects of anthropogenic activities against this background of fluctuations in the natural world. With the frustratingly large, diverse, and ever-emerging sphere of envi ronmental problems that ecotoxicology must address, the approaches to individual problems also must vary. In part, as a consequence, there is no established protocol for application of the science to environmental prob lem-solving. The conceptual and methodological bases for ecotoxicology are, how ever, in their infancy, and thus still growing with new experiences. In deed, the only robust generalization for research on different ecosystems and different chemical stresses seems to be a recognition of the necessity of an ecosystem perspective as focus for assessment. This ecosystem basis for ecotoxicology was the major theme of a previous pUblication by the Ecosystems Research Center at Cornell University, a special issue of Environmental Management (Levin et al. 1984). With that effort, we also recognized an additional necessity: there should be a continued develop ment of methods and expanded recognition of issues for ecotoxicology and for the associated endeavor of environmental management.

Download or read book Constructed Wetlands for Wastewater Treatment written by Donald A. Hammer and published by CRC Press. This book was released on 1989-10-31 with total page 860 pages. Available in PDF, EPUB and Kindle. Book excerpt: Both practical and theoretical, this book provides the basic principles of soil chemistry, hydrology, wetland ecology, microbiology, vegetation and wildlife as a sound introduction to this innovative technology to treat toxic wastewaters and sludges. The use of wetlands for acid mine drainage, and metals removal in municipal, urban runoff, and industrial systems is discussed. Case histories are also presented, demonstrating specific types of constructed wetlands and applications to municipal wastewater, home sites, coal and non-coal mining, coal-fired electric power plants, chemical and pulp industry, agriculture, landfill leachate, and urban stormwater. Construction and management guidelines are clearly explained, providing information on applicable policies and regulations, siting and construction, and operations and monitoring of constructed wetlands treatment systems. Recent theoretical and empirical results from operating systems and research facilities, including such new applications as nutrient removal from eutrophic lakes and urban stormwater treatment within highway rights-of-way, are included. This book is an ideal resource for wastewater treatment plants, consulting engineers, federal and state regulators, industrial environmental managers, municipalities, environmental health professionals, and ecologists.
