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 The Condor s Shadow written by David S. Wilcove and published by Anchor. This book was released on 2000-05-09 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: With gripping narrative power, The Condor's Shadow traces the ways in which human greed and ignorance have wreaked havoc on our ecological landscape. The heir apparent to Peter Matthiessen's 1959 classic Wildlife in America, The Condor's Shadow is a brilliant and compulsively readable study of the state of North American wildlife and what is being done to reverse the damage humans have caused. With equal respect for the smallest feather-mite and the fiercest grizzly, the frailest flower and the stateliest redwood, David S. Wilcove illustrates--in jargon-free, often witty prose--nature's delicate system of checks and balances, examining the factors that determine a species' vulnerability and the consequences of losing even the tiniest part of any ecosystem. An examination of both the heart-wrenching failures and stunning successes of our conservation efforts, The Condor's Shadow chronicles the destruction and resilience of our American wilderness and offers an insightful, eloquent overview that will appeal to avid conservationists and recreational nature-lovers alike.

Download or read book Endangered and Threatened Fishes in the Klamath River Basin written by National Research Council and published by National Academies Press. This book was released on 2004-04-30 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1988 the U.S. Fish and Wildlife Service listed two endemic fishes of the upper Klamath River basin of Oregon and California, the sucker and the Lost River sucker, as endangered under the federal Endangered Species Act (ESA). In 1997, the National Marine Fisheries Service added the Southern Oregon Northern coastal California (SONCC) coho salmon as a threatened species to the list. The leading factors attributed to the decline of these species were overfishing, blockage of migration, entrainment by water management structures, habitat degradation, nonnative species, and poor water quality. Endangered and Threatened Fishes of the Klamath River Basin addresses the scientific aspects related to the continued survival of coho salmon and shortnose and Lost River suckers in the Klamath River. The book further examines and identifies gaps in the knowledge and scientific information needed for recovery of the listed species and proves an assessment of scientific considerations relevant to strategies for promoting the recovery of those species.

Aiken, South Carolina Domy C. Adriano Coordinating Editor Preface to Acidic Precipitation, Volume 4 (Advances in Environmental Science) Acidic precipitation and its effects have been the focus ofintense research for over two decades. Initially, research centered on the acidity status and acidification of surface waters and consequent impact on the status of sports fisheries; evidence suggested impacts on fisheries in Sweden and Norway, and in North America, in eastern Ontario, Quebec, and in the Adirondack Mountains of New York.

Download or read book Three Dimensional Eutrophication Model of Lake Washington Washington State written by and published by . This book was released on 2004 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lake Washington is one of a system of three lakes located in northwestern Washington State (Figure 1 - 1). The lake provides a textbook example of eutrophication remediation through reduction of nutrient loads. The decline and recovery of the lake are the subject of a series of classic works by W. T. Edmondson, his students, and co-workers (Edmondson 1972; Edmondson and Lehman 1981; Edmondson 1991; Edmondson 1994). The description of the lake in this chapter is derived from these sources as well as from a Web site maintained by the King County Department of Natural Resources and Parks (http ://dnr/metrokc. gov/wlr/waterres/lakes/Monitor. htm). Lake Washington was formed at the end of an ice age roughly 12,000 years ago. Within historic times, the lake had one major inflow at its northern end, the Sammamish River, which drains Lake Sammamish. The outlet was the Black River at the southern end. The Black River flowed into the Cedar River, which led to Puget Sound. In 1916, a locked ship canal was constructed that connected Lake Washington with Puget Sound through Lake Union to the west. The level of Lake Washington was lowered by 3.3 m, and the Cedar River was converted from an outflow to an inflow. The major outflow was now through the Chittenden locks at the western end of Lake Union.
Download or read book Lake Chilwa written by M. Kalk and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Leonard C. Beadle In contrast to the more sta bie oceans, inland waters are, on the geological time scale, short-lived and are subject to great fluctuations in chemical composition and physical features. Very few lakes and rivers have existed continuously for more than a million years, and the life of the majority is to be measured in thousands or less. Earth movements, erosion and long-term climatic changes in the past have caused many of them to appear and disappear. No wonder then that most freshwater organism are especially adapted to great changes and many even to temporary extinction of their environment. Recent studies of residual sediments from existing and extinct lakes in tropical Africa have told us much about their age and the past history of their faunas and floras, from which we may deduce something about the climate and the conditions in the water in the past. The forces that have formed and moulded the African Great Lakes have been catastrophic in their violence and effects. They are not yet finished, but the present rate of change is, in human terms, too slow for direct observation of the ecological effects. The large man-made lakes are providing very good opportunities for studying the chemi cal and biological consequences of the initial filling but, once filled, they are artificially protected against major fluctuations.
