Book excerpt: Return to the River will describe a new ecosystem-based approach to the restoration of salmon and steelhead populations in the Columbia River, once one of the most productive river basins for anadromous salmonids on the west coast of North America. The approach of this work has broad applicability to all recovery efforts throughout the northern hemisphere and general applicability to fisheries and aquatic restoration efforts throughout the world. The Pacific Northwest is now embroiled in a major public policy debate over the management and restoration of Pacific salmon. The outcome of the debate has the potential to affect major segments of the region's economy - river transportation, hydroelectric production, irrigated agriculture, urban growth, commercial and sport fisheries, etc. This debate, centered as it is on the salmon in all the rivers, has created a huge demand for information. The book will be a powerful addition to that debate. - A 15 year collaboration by a diverse group of scientists working on the management and recovery of salmon, steelhead trout, and wildlife populations in the Pacific Northwest - Includes over 200 figures, with four-color throughout the book - Discusses complex issues such as habitat degradation, juvenile survival through the hydrosystem, the role of artificial production, and harvest reform

Download or read book Systems Analysis and Simulation in Ecology written by Bernard C. Patten and published by Elsevier. This book was released on 2013-09-17 with total page 609 pages. Available in PDF, EPUB and Kindle. Book excerpt: Systems Analysis and Simulation in Ecology, Volume II, concludes the original concept for Systems Analysis and Simulation in Ecology, and at the same time initiates a continuing series under the same title. The original idea, in 1968, was to draw together a collection of systems ecology articles as a convenient benchmark to the state of this emerging new field and as a stimulus to broader interest. These purposes will continue to motivate the series in highlighting, from time to time, accomplishments, trends, and prospects. The present volume is organized into four parts. Part I outlines for ecologists the concepts upon which systems science as a discipline is built. Part II presents example applications of systems analysis methods to ecosystems. Part III is devoted to new theory, including an investigation into the feasibility of several nonlinear formulations for use in compartment modeling of ecosystems; and the important topic of connectivity in systems. Part IV presents a sampling of systems ecology applications. It provides a reasonably balanced and accurate picture of the practical capability of ecological systems analysis and simulation. Performance does not come up to publicity, but prospects for rapid improvement are good given a willingness to let pragmatism guide sound scientific development without demanding unrealistic short-term successes.
Download or read book Methods in Ecosystem Science written by Osvaldo E. Sala and published by Springer Science & Business Media. This book was released on 2013-12-01 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecology at the ecosystem level has both necessitated and benefited from new methods and technologies as well as those adapted from other disciplines. With the ascendancy of ecosystem science and management, the need has arisen for a comprehensive treatment of techniques used in this rapidly-growing field. Methods in Ecosystem Science answers that need by synthesizing the advantages, disadvantages and tradeoffs associated with the most commonly used techniques in both aquatic and terrestrial research. The book is divided into sections addressing carbon and energy dynamics, nutrient and water dynamics, manipulative ecosystem experiements and tools to synthesize our understanding of ecosystems. Detailed information about various methods will help researchers choose the most appropriate methods for their particular studies. Prominent scientists discuss how tools from a variety of disciplines can be used in ecosystem science at different scales.

Download or read book Eugene Odum written by Betty Jean Craige and published by University of Georgia Press. This book was released on 2002 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Students of nature around the world revere Eugene Odum as a founder and pioneer of ecosystem ecology. In this biography of Odum, Betty Jean Craige depicts the intellectual growth, creativity, and vision of the scientist who made the ecosystem concept central to his discipline and translated the principles of ecosystem ecology into lessons in preserving the natural environment. Placing Odum's achievements in historical context, Craige traces his life from his childhood through his education, his collaboration with his brother Howard T. Odum in developing methods to study ecosystems, his contributions to the field of radiation ecology, his emergence as an internationally distinguished educator of ecosystem ecology, and his environmental activism. Craige also describes Odum's role in the creation of the Savannah River Ecology Laboratory, the Marine Institute on Sapelo Island, and the Institute of Ecology at the University of Georgia, where he became identified with the statement "The ecosystem is greater than the sum of its parts." Odum's textbook Fundamentals of Ecology is a classic, published in numerous editions and translations worldwide. Odum achieved membership in the National Academy of Sciences, shared with his brother the prestigious Crafoord Prize for Ecology, accepted six honorary doctorates, and received numerous awards for environmental activities.
Download or read book Estuarine and Wetland Processes written by Keith B. Ater and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estuaries and Wetlands are important coastal resources which are subject to a great deal of environmental stress. Dredging, construction, creation of intertidal wetlands, regulation of fresh water flow, and pollution are just a few of the activities which affect these coastal systems. The need to predict the effects of these perturbations upon ecosystem dynamics, particularly estuarine fisheries, as well as on physical effects, such as sedimentation and salt intrusion, is of paramount importance. Prediction requires the use of models, but no model is likely to be satisfactory unless fundamental physical, chemical, sedimentological, and biological processes are quantitatively understood, and the appropriate time and space scales known. With these considerations in mind, the Environmental Laboratory, U. S. Army Engineer Haterways Experiment Station,* Vicksburg, Mississippi, sponsored a workshop on "Estuarine and Wetland Processes and Water Quality Modeling" held in New Orleans, June 1979. The contents of this volume have been selected from the workshop papers. The resulting book, perhaps more than any other symposium proceed ings on estuaries and wetlands, attempts to review important pro cesses and place them in a modeling context. There is also a distinct applied tinge to a number of the contributions since some of the research studies were motivated by environmental assessments. The difference in title between this volume and the workshop re flects more accurately the contents of the published papers.
