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 Trace Metals in the Environment and Living Organisms written by Philip S. Rainbow and published by Cambridge University Press. This book was released on 2018-08-23 with total page 767 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trace metals play key roles in life - all are toxic above a threshold bioavailability, yet many are essential to metabolism at lower doses. It is important to appreciate the natural history of an organism in order to understand the interaction between its biology and trace metals. The countryside and indeed the natural history of the British Isles are littered with the effects of metals, mostly via historical mining and subsequent industrial development. This fascinating story encompasses history, economics, geography, geology, chemistry, biochemistry, physiology, ecology, ecotoxicology and above all natural history. Examples abound of interactions between organisms and metals in the terrestrial, freshwater, estuarine, coastal and oceanic environments in and around the British Isles. Many of these interactions have nothing to do with metal pollution. All organisms are affected from bacteria, plants and invertebrates to charismatic species such as seals, dolphins, whales and seabirds. All have a tale to tell.

Download or read book Evaluating and Monitoring the Health of Large Scale Ecosystems written by David J. Rapport and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecosystem health offers a fresh perspective on the management of natural resources and the environment. While some of the root concepts can surely be traced back to Aldo Leopold and even earlier, it is only in the recent decade that a substantial body of work has emerged on this topic. There is no question that a novel approach which is by its nature cross disciplinary, bridging the health and biological sciences, will initially raise a number of questions particularly pertaining to the use of metaphors and the validity of the analogy. This volume however goes beyond merely the philosophical dimensions of the subject by covering a number of case studies which have given rise to the development of promising quantitative methods for diagnosis and rehabilitation of ecosystems under stress. The focus of most studies is on regional ecosystems i.e. ecosystems of large scale. As such, the methods and approaches should have wide appeal to government agencies charged with the responsibility of sustainable development of regional ecosystems and natural resources. Health is one of those difficult concepts that everyone thinks they can define, until they come to try. We all have personal knowledge about health and illness and this makes the ecosystem analogy so potentially powerful. Yet it is also clear that the uncritical application of the concept could lead to overly simplistic approaches to analysis and management of ecosystem health.

Download or read book Chemicals in the Aquatic Environment written by Lars Landner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hazard assessment of a compound (xenobiotic) discharged to the aquatic environment requires data on both exposure and effects to various components of the ecosystem. The multitude of ecological gradients in the Baltic Sea is used as a background example for discussing the complexity of the issue and the need for new approaches. Therefore, this book attempts to go beyond the simplistic, standardized short-term laboratory tests traditionally used as a basis for hazard assessment of chemicals, and gives strong emphasis to the interpretation of ecotoxicological data in their real, ecological context, pointing out the need to consider the natural mortality distribution of the population under study, the role of keystone species and of species with broad ecological niches versus those with narrow, specialized niches.
Download or read book Organic Chemicals in the Aquatic Environment written by Alasdair H. Neilson and published by CRC Press. This book was released on 2018-01-18 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic Chemicals in the Aquatic Environment draws from the author's experience with a variety of problems dealing with the fate, distribution, and toxicity of organic compounds in the aquatic environment. It discusses the basic issues of chemical analysis, distribution, persistence, and ecotoxicology, with an emphasis on microbial reactions. The necessary input and the difficulties of achieving a rigorous synthesis of the various elements are illustrated with specific examples. The book includes a wide range of structurally diverse compounds as illustration and presents a mechanistic approach to biodegradation and biotransformation. The final chapter addresses the issue of environmental hazard assessment and constructs a strategy for carrying it out.
Download or read book Manual of Bioassessment of Aquatic Sediment Quality written by Alena Mudroch and published by CRC Press. This book was released on 1998-09-17 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Past generations of industrial development and chemical production are still very much with us-through contaminants they've left in all phases of the ecosystem. Especially vulnerable to this damage: water. Professionals from various disciplines in environmental sciences are becoming increasingly involved in water quality issues. The Manual of Bioassessment of Aquatic Sediment Quality now provides the most current techniques and methods, in the laboratory and the field, to detect and evaluate aquatic contaminants. Designed to complement the analytical methods presented in the companion volume, Manual of Physico-Chemical Analysis of Aquatic Sediments, the Bioassessment edition offers a comprehensive review of chemical forms, encompassing different elements and compounds in sediments, along with evaluation of their availability to aquatic biota. A discussion about the use of reference materials in sediment analysis also accompanies a review of laboratory safety measures. While greater environmental conscientiousness has led to sustainable industrial development and the recycling of materials, there remains the "hidden need" to remediate contaminated water sources throughout the world-essential to the continued survival of all life. The Manual of Bioassessment of Aquatic Sediment Quality will help environmental professionals ensure the protection of life-supporting streams, lakes and oceans throughout the world.
