Download or read book Riparian Areas written by National Research Council and published by National Academies Press. This book was released on 2002-10-10 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2009-05 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report by the Nat. Science and Tech. Council¿s U.S. Climate Change Science Program (CCSP) is part of a series of 21 reports aimed at providing current assessments of climate change science to inform public debate, policy, and operational decisions. These reports are also intended to help the CCSP develop future program research priorities. The CCSP¿s guiding vision is to provide the Nation and the global community with the science-based knowledge needed to manage the risks and capture the opportunities associated with climate and related environmental changes. This report assesses the effects of climate change on U.S. land resources, water resources, agriculture, and biodiversity. It was developed with broad scientific input. Illus.

Download or read book Urban Stormwater Management in the United States written by National Research Council and published by National Academies Press. This book was released on 2009-03-17 with total page 611 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.

Download or read book Freshwater Meiofauna written by Simon D. Rundle and published by . This book was released on 2002 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Meiofauna are a diverse and numerous component of the fauna in freshwater ecosystems, but have been mostly ignored by freshwater scientists. Freshwater Meiofauna aims to raise the awareness of this enigmatic, microscopic component of the freshwater biota, by providing the first-ever, comprehensive review of their biology and ecology. The first section of the book gives indepth accounts of the systematics, morphological characteristics, life histories and ecological requirements of the main freshwater meiofaunal taxa (i.e. microturbellarians, rotifers, gastrotriches, nematodes, water mites, microcrustaceans and tardigrades). The second section then takes an integrated approach to review the current state-of-play in meiofaunal ecological research in freshwaters, addressing important issues, such as the importance of meiofaunal taxa in the trophic dynamics of freshwater ecosystems and the process underpinning the distribution patterns observed in meiofaunal assemblages. This book should appeal to a wide range of freshwater scientists, including novices in the study of freshwater meiobenthology and established researchers in freshwater ecology, for whom the meiofauna represent an unopened "black box". Our ultimate goal is that this book will serve to promote the idea that the zoology of freshwater habitats concerns more than just fish, macroinvertebrates and microbes.
