Available in PDF, EPUB and Kindle. Book excerpt: The importance of salmon to the Pacific Northwestâ€"economic, recreational, symbolicâ€"is enormous. Generations ago, salmon were abundant from central California through Idaho, Oregon, and Washington to British Columbia and Alaska. Now they have disappeared from about 40 percent of their historical range. The decline in salmon numbers has been lamented for at least 100 years, but the issue has become more widespread and acute recently. The Endangered Species Act has been invoked, federal laws have been passed, and lawsuits have been filed. More than $1 billion has been spent to improve salmon runsâ€"and still the populations decline. In this new volume a committee with diverse expertise explores the complications and conflicts surrounding the salmon problemâ€"starting with available data on the status of salmon populations and an illustrative case study from Washington state's Willapa Bay. The book offers specific recommendations for salmon rehabilitation that take into account the key role played by genetic variability in salmon survival and the urgent need for habitat protection and management of fishing. The committee presents a comprehensive discussion of the salmon problem, with a wealth of informative graphs and charts and the right amount of historical perspective to clarify today's issues, including: Salmon biology and geographyâ€"their life's journey from fresh waters to the sea and back again to spawn, and their interaction with ecosystems along the way. The impacts of human activitiesâ€"grazing, damming, timber, agriculture, and population and economic growth. Included is a case study of Washington state's Elwha River dam removal project. Values, attitudes, and the conflicting desires for short-term economic gain and long-term environmental health. The committee traces the roots of the salmon problem to the extractive philosophy characterizing management of land and water in the West. The impact of hatcheries, which were introduced to build fish stocks but which have actually harmed the genetic variability that wild stocks need to survive. This book offers something for everyone with an interest in the salmon issueâ€"policymakers and regulators in the United States and Canada; environmental scientists; environmental advocates; natural resource managers; commercial, tribal, and recreational fishers; and concerned residents of the Pacific Northwest.

This book was released on 2014-04-05 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: With a long history and deep connection to the Earth’s resources, indigenous peoples have an intimate understanding and ability to observe the impacts linked to climate change. Traditional ecological knowledge and tribal experience play a key role in developing future scientific solutions for adaptation to the impacts. The book explores climate-related issues for indigenous communities in the United States, including loss of traditional knowledge, forests and ecosystems, food security and traditional foods, as well as water, Arctic sea ice loss, permafrost thaw and relocation. The book also highlights how tribal communities and programs are responding to the changing environments. Fifty authors from tribal communities, academia, government agencies and NGOs contributed to the book. Previously published in Climatic Change, Volume 120, Issue 3, 2013.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Quantitative modeling methods have become a central tool in the management of harvested fish populations. This book examines how these modeling methods work, why they sometimes fail, and how they might be improved by incorporating larger ecological interactions. Fisheries Ecology and Management provides a broad introduction to the concepts and quantitative models needed to successfully manage fisheries. Walters and Martell develop models that account for key ecological dynamics such as trophic interactions, food webs, multi-species dynamics, risk-avoidance behavior, habitat selection and density-dependence. They treat fisheries policy development as a two-stage process, first identifying strategies for varying harvest in relation to changes in abundance, then finding ways to implement such strategies in terms of monitoring and regulatory procedures. This book provides a general framework for developing assessment models in terms of state-observation dynamics hypotheses, and points out that most fisheries assessment failures have been due to inappropriate observation model hypotheses rather than faulty models for ecological dynamics. Intended as a text in upper division and graduate classes on fisheries assessment and management, this useful guide will also be widely read by ecologists and fisheries scientists.

Download or read book Trout written by Sergio Polakof and published by Nova Science Pub Incorporated. This book was released on 2013 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trout are generally considered to be cool, freshwater fish species that belong phylogenetically to the rather young group of fin-rayed or Teleost fishes in the Family Salmonidae. Trout have significant economic, social and scientific importance. This book examines two 'trout', the rainbow trout Oncorhynchus mykiss and the brown trout Salmo trutta. This book came from the editor's interest to bring together some of the major areas that have made 'trout' such an important and enduring model species. The chapters have been carefully crafted by their authors to ensure that they cover as much of the topic as possible including references that support the information.
