Download or read book Global Climate Change and Freshwater Ecosystems written by Penelope Firth and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global climate change is a certainty. The Earth's climate has never remained static for long and the prospect for human-accelerated climate change in the near future appears likely. Freshwater systems are intimately connected to climate in several ways: they may influence global atmospheric processes affecting climate; they may be sensitive early indicators of climate change because they integrate the atmospheric and terrestrial events occurring in their catchments; and, of course, they will be affected by climate change. An improved predictive understanding of environmental effects on pattern and process in freshwater ecosystems will be invaluable as a baseline upon which to build sound protection and management policies for fresh waters. This book represents an early step towards this improved understanding. The contributors accepted the challenge to assume global warming of 2-5oC in the next century. They then explored the implications of this scenario on various freshwater ecosystems and processes. To provide a broader perspective, Firth and Fisher included several chapters which do not deal expressly with freshwater ecosystems, but rather discuss climate change in terms of causes and mechanisms, implications for water resources, and the use of remote sensing as a tool for expanding studies from local to global scale.
Download or read book Biological Monitoring of Aquatic Systems written by Stanford, L. Loeb and published by CRC Press. This book was released on 1994-01-24 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: With regional, national, and global processes affecting both the structure and function of lakes and rivers, assessment methodology must encompass many attributes to evaluate the impact of these processes on water quality. Many of the changes in biological communities correlate to resource exploitation, nonpoint pollutant interactions, and habitat alteration - factors that can be missed by routine chemical sampling. This creates the need for ecologically-based approaches to this problem. Biological monitoring is a fundamental part of an ecologically-based approach. Biological Monitoring of Aquatic Systems brings together contributions by authors recognized as leaders in the development and utilization of biological monitoring techniques for freshwater ecosystems. It provides a conceptual framework for the use of biological monitoring to assess the environmental health of freshwater resources. Biological monitoring is an important part of any water quality assessment program. Biological Monitoring of Aquatic Systems provides you with an understanding of water resources. It includes discussions concerning historical development, ecological basis, experimental design characteristics, case studies, and future concerns. As efforts to maintain and restore the world's water resources intensify, the need to develop accurate methods to assess the health of these resources becomes critical.

Download or read book Acidic Deposition and Aquatic Ecosystems written by Donald F. Charles and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 742 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acidic deposition and its effect on aquatic ecosystems have become major scientific and public policy issues in the United States since the early 1970s, and many diverse studies have been completed. This book is the first comprehensive, integrated synthesis of available information on current and potential effects of acidic precipitation on lakes and streams in geographic regions with a high number of low-alkalinity surface water from the Adirondacks and the Southern Blue Ridge to the Upper Midwest to the Rocky Mountains, the Sierra Nevada, and the Cascades. Written by leading authors, the book examines the current status of water chemistry and characterizes the processes controlling water chemistry on a regional basis by using and comparing high-quality data sets. Methods for the assessment of long-term changes in water chemistry and their effects in fish and other biota are also presented. The book amply illustrates the substantial diversity among geographical regions with respect to the nature of surface waters and the complexity of their response to acidic deposition. This volume will be of great interest to researchers in limnology, aquatic ecology, environmental chemistry, hydrology, and atmospheric sciences. It will also serve as an important reference for environmental managers and policy makers.

Book excerpt: Today environmental problems of unprecedented magnitude confront planet earth. The sobering fact is that a whole range of human activities is affecting our global environment as profoundly as the billions of years of evolution that preceded our tenure on Earth. The pressure on vital natural resources in the developing world and elsewhere is intense, and the destruction of tropical forests, wildlife habitat, and other irreplaceable resources, is alarming. Climate change, ozone depletion, loss of genetic diversity, and marine pollution are critical global environmental concerns. Their cumulative impact threatens to destroy the planet's natural resources. The need to address this situation is urgent. More than at any previous moment in history, nature and ecological systems are in human hands, dependent on human efforts. The earth is an interconnected and interdependent global ecosystem, and change in one part of the system often causes unexpected change in other parts. Atmospheric, oceanic, wetland, terrestrial and other ecological systems have a finite capacity to absorb the environmental degradation caused by human behavior. The need for an environmentally sound, sustainable economy to ease this degradation is evident and urgent. Policies designed to stimulate economic development by foregoing pollution controls both destroy the long-term economy and ravage the environment. Over the years, we have sometimes drawn artificial distinctions between the health of individuals and the health of ecosystems. But in the real world, those distinctions do not exist.

Book excerpt: The first Wild Trout Symposium (1974) was sponsored by Trout Unlimited and the United States Department of the Interior. The second Symposium (1979) added the Federation of Fly Fisherman as a sponsor. Five years later (1984) the U.S. Department of Agriculture - Forest Service joined. In 1989 , the U.S. Environmental Protection Agency and the American Fisheries Society joined. These symposia began with a concentration on management, then recognized that more than 'management' was required in ongoing efforts to enhance wild salmonid fisheries. Subsequent symposia began to examine a broader range of environmental and social factors influencing wild salmonids. The originators hoped that each symposium would be a building block upon which the succeeding symposium could provide insights and research which future sessions could revisit. Along with the broadening of sponsorship, we have grown , we have gained recognition, and we look forward to expanding our contribution to the cause of wild salmonids. We hope these Proceedings will stimulate readers thinking and efforts on behalf of our wild salmonid resources , and plan to participate with us in Wild Trout V.
