Book Synopsis Riparian Areas by : National Research Council
Download or read book Riparian Areas written by National Research Council and published by National Academies Press. This book was released on 2002-10-10 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.

Book Synopsis Stock Identification Methods by : Steven X. Cadrin
Download or read book Stock Identification Methods written by Steven X. Cadrin and published by Academic Press. This book was released on 2013-10-04 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stock Identification Methods, 2e, continues to provide a comprehensive review of the various disciplines used to study the population structure of fishery resources. It represents the worldwide experience and perspectives of experts on each method, assembled through a working group of the International Council for the Exploration of the Sea. The book is organized to foster interdisciplinary analyses and conclusions about stock structure, a crucial topic for fishery science and management. Technological advances have promoted the development of stock identification methods in many directions, resulting in a confusing variety of approaches. Based on central tenets of population biology and management needs, this valuable resource offers a unified framework for understanding stock structure by promoting an understanding of the relative merits and sensitivities of each approach. - Describes 18 distinct approaches to stock identification grouped into sections on life history traits, environmental signals, genetic analyses, and applied marks - Features experts' reviews of benchmark case studies, general protocols, and the strengths and weaknesses of each identification method - Reviews statistical techniques for exploring stock patterns, testing for differences among putative stocks, stock discrimination, and stock composition analysis - Focuses on the challenges of interpreting data and managing mixed-stock fisheries

Book Synopsis Expanding Mariculture Farther Offshore by : Alessandro Lovatelli
Download or read book Expanding Mariculture Farther Offshore written by Alessandro Lovatelli and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2013 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is also recommended that efforts be increased to farm lower trophic levels species and optimize feeds and feeding in order to minimize ecosystems impacts and ensure long-term sustainability. Similarly, risk assessments and/or environmental impact assessment and monitoring must always be in place before establishing offshore farms, and permanent environmental monitoring must be ensured. All coastal nations should be prepared to engage actively in developing the technological, legal and financial frameworks needed to support the future development of offshore mariculture to meet global food needs. The workshop report highlights the major opportunities and challenges for a sustainable mariculture industry to grow and further expand off the coast.

Book Synopsis Adaptive Environmental Assessment and Management by : C. S. Holling
Download or read book Adaptive Environmental Assessment and Management written by C. S. Holling and published by . This book was released on 1978 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book develops an adaptive approach to environmental impact assessment and management and is based on a study initiated by a workshop convened in early 1974 by SCOPE (Scientific Committee on Problems of the Environment). CS Holling discusses the nature and behavior of ecological systems and its issues, limitations, and potential of environmental assessment. Further, he discusses how we can incorporate impact assessment studies with actual environmental planning and decision making.Crawford Holling received his B.A. and M.Sc. at the University of Toronto (1952) and his Ph.D. at the University of British Columbia (1957). He worked in the laboratories of the Department of the Environment, Government of Canada. Since then, he has been, at various times, Professor and Director of the Institute of Resource Ecology, University of British Columbia, Vancouver, Canada, and Director of the International Institute for Applied Systems Analysis (IIASA), Vienna, Austria. He now occupies the Arthur R. Marshall Jr. Chair in Ecological Sciences at the University of Florida and has launched a comparative study of the structure and dynamics of ecosystems.
Book Synopsis North Pacific Temperate Rainforests by : Gordon H. Orians
Download or read book North Pacific Temperate Rainforests written by Gordon H. Orians and published by University of Washington Press. This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The North Pacific temperate rainforest, stretching from southern Alaska to northern California, is the largest temperate rainforest on earth. This book provides a multidisciplinary overview of key issues important for the management and conservation of the northern portion of this rainforest, located in northern British Columbia and southeastern Alaska. This region encompasses thousands of islands and millions of acres of relatively pristine rainforest, providing an opportunity to compare the ecological functioning of a largely intact forest ecosystem with the highly modified ecosystems that typify most of the world's temperate zone. The book examines the basic processes that drive the dynamic behavior of such ecosystems and considers how managers can use that knowledge to sustainably manage the rainforest and balance ecosystem integrity with human use. Together, the contributors offer a broad understanding of the challenges and opportunities faced by scientists, managers, and conservationists in the northern portion of the North Pacific rainforest that will be of interest to conservation practitioners seeking to balance economic sustainability and biodiversity conservation across the globe. Gordon Orians is professor emeritus of biology at the University of Washington. John Schoen is a senior science advisor at Audubon Alaska. Other contributors include Paul Alaback, Bill Beese, Frances Biles, Todd Brinkman, Joe Cook, Lisa Crone, Dave D'Amore, Rick Edwards, Jerry Franklin, Ken Lertzman, Stephen MacDonald, Andy MacKinnon, Bruce Marcot, Joe Mehrkens, Eric Norberg, Gregory Nowacki, Dave Person, and Sari Saunders.

Book Synopsis Analytical Approaches to Assessing Recovery Options for Snake River Chinook Salmon by : Phaedra Budy
Download or read book Analytical Approaches to Assessing Recovery Options for Snake River Chinook Salmon written by Phaedra Budy and published by Createspace Independent Pub. This book was released on 2012-08-23 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The depressed status of Snake River stocks of chinook and steelhead and the recent listings of many salmon stocks in the Columbia Basin have led to several analytical evaluations and management advice aimed at recovery of these stocks. These different analytical reviews address the effectiveness of different hydrosystem options as well as the potential for recovery through improvements that increase survival at other life stages (e.g., habitat, harvest). Hydrosystem options evaluated included status quo, maximizing transportation, and the option of breaching the lower four dams on the Snake River (also called drawdown and natural river options), the main topic of the Lower Snake River Juvenile Salmon Migration Feasibility Report / Environmental Impact Statement (USACE). The first review was completed by PATH (Plan for Testing and Analyzing Hypotheses), an open forum composed of modelers, fishery biologists and statisticians from all three states (Oregon, Washington, and Idaho), the federal government (Army Corps of Engineers (USACE), US Fish and Wildlife Service (USFWS), National Marine Fishery Service (NMFS), Bonneville Power Administration (BPA), the treaty tribes of the Columbia Basin (represented by the Columbia River Inter-tribal Fish Commission -CRITFC), and the Northwest Power Planning Council (NPPC). The PATH approach was based on a decision analysis that showed which management actions are the most robust to remaining uncertainties (i.e. the least risky) and allows a decision to be made with full consideration of uncertainty and risk. PATH analyses were followed by the NMFS effort called CRI- the Cumulative Risk Initiative. CRI analyses explore the demographic effects of hypothetical reductions in mortality at different life stages based on current conditions. PATH and CRI analyses were followed by an analytical comparison of their approaches and results completed by a sub group of PATH composed of scientists from the states of Oregon, Idaho, Washington, CRITFC, and the USFWS. In addition, specific analyses have considered the potential for improvement at certain life stages (e.g., freshwater spawning and rearing; Petrosky et al., in press) and key uncertainties that affect the likely effectiveness of dam breach (e.g., delayed hydrosystem mortality; Budy et al., in review). This annex synthesizes analyses and results PATH, NMFS CRI, and comparative and follow-up analyses which have been completed since and are summarized here and described in greater detail elsewhere. Although the results vary somewhat among approaches, all available science appears to suggest that dam breach has the greatest biological potential for recovering Snake River salmon and steelhead.
