Available in PDF, EPUB and Kindle. Book excerpt: As pressures on Australia's inland waters intensify from population growth, expanding resource development and climate change, there is an urgent need to manage and protect these special areas. Understanding their ecology underpins their wise management and conservation. Australian Freshwater Ecology vividly describes the physical, chemical and biological features of wetlands, lakes, streams, rivers and groundwaters in Australia. It presents the principles of aquatic ecology linked to practical management and conservation, and explains the causes, mechanisms, effects and management of serious environmental problems such as altered water regimes, eutrophication, salinization, acidification and sedimentation of inland waters. Key features: contributions from a diverse, highly qualified team of aquatic ecologists whose expertise spans the ecology and management of standing and running waters in Australia sections covering groundwaters, biodiversity, temporary and tropical waters, climate change, invasive species and freshwater conservation numerous Australian case-studies and guest 'text-boxes' showing management in practice concise descriptions of ecological processes and conceptual models illustrated with original, high- quality diagrams and photographs Readable and logically structured, this text supports undergraduate and postgraduate courses in aquatic ecology and management. It is a valuable reference for consultants, restoration ecologists, water resource managers, science teachers, and other professionals with an interest in the ecology of surface and groundwaters.

Download or read book Regional Cooperation for Water Quality Improvement in Southwestern Pennsylvania written by National Research Council and published by National Academies Press. This book was released on 2005-04-04 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: The city of Pittsburgh and surrounding area of southwestern Pennsylvania face complex water quality problems, due in large part to aging wastewater infrastructures that cannot handle sewer overflows and stormwater runoff, especially during wet weather. Other problems such as acid mine drainage are a legacy of the region's past coal mining, heavy industry, and manufacturing economy. Currently, water planning and management in southwestern Pennsylvania is highly fragmented; federal and state governments, 11 counties, hundreds of municipalities, and other entities all play roles, but with little coordination or cooperation. The report finds that a comprehensive, watershed-based approach is needed to effectively meet water quality standards throughout the region in the most cost-effective manner. The report outlines both technical and institutional alternatives to consider in the development and implementation of such an approach.

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.
