Download or read book Physiological Ecology of Pacific Salmon written by Cornelis Groot and published by UBC Press. This book was released on 2010-10-01 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every year, countless juvenile Pacific salmon leave streams and rivers on their migration to feeding grounds in the North Pacific Ocean and the Bering Sea. After periods ranging from a few months to several years, adult salmon enter rivers along the coasts of Asia and North America to spawn and complete their life cycle. Within this general outline, various life history patterns, both among and within species, involve diverse ways of exploiting freshwater, estuarine, and marine habitats. There are seven species of Pacific salmon. Five (coho, chinook chum, pink, and sockeye) occur in both North America and Asia. Their complex life histories and spectacular migrations have long fascinated biologists and amateurs alike. Physiological Ecology of Pacific Salmon provides comprehensive reviews by leading researchers of the physiological adaptations that allow Pacific Salmon to sustain themselves in the diverse environments in which they live. It begins with an analysis of energy expenditure and continues with reviews of locomotion, growth, feeding, and nutrition. Subsequent chapters deal with osmotic adjustments enabling the passage between fresh and salt water, nitrogen excretion and regulation of acid-base balance, circulation and gas transfer, and finally, responses to stress. This thorough and authoritative volume will be a valuable reference for students and researchers of biology and fisheries science as they seek to understand the environmental requirements for the perpetuation of these unique and valuable species.

Download or read book Yup ik Eskimo Dictionary written by and published by Alaska Native Language Center. This book was released on 2012 with total page 722 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most comprehensive Yup'ik dictionary in existence, the second edition of this important work now adds extensive research on Central Alaskan Yup'ik, enhancing the forty years of research done by Steven A. Jacobson on the Yup'ik language and dialects. Over these decades, Jacobson has combed through records of explorers, linguists, missionaries, and anyone who has come in contact with the actively migratory Yup'ik people. Combined with information from native Yup'ik speakers, that research has led to a richly detailed dictionary that covers the entire language and all its dialects. The dictionary also offers sections on Yup'ik spelling, early vocabulary, demonstrative words, and important intersections of Yup'ik language and culture such as the kayak, dogsled, parka, and old-style dwellings.

Download or read book Salmon Without Rivers written by Jim Lichatowich and published by . This book was released on 1999-08 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Fundamentally, the salmon's decline has been the consequence of a vision based on flawed assumptions and unchallenged myths.... We assumed we could control the biological productivity of salmon and 'improve' upon natural processes that we didn't even try to understand. We assumed we could have salmon without rivers." --from the introduction From a mountain top where an eagle carries a salmon carcass to feed its young to the distant oceanic waters of the California current and the Alaskan Gyre, salmon have penetrated the Northwest to an extent unmatched by any other animal. Since the turn of the twentieth century, the natural productivity of salmon in Oregon, Washington, California, and Idaho has declined by eighty percent. The decline of Pacific salmon to the brink of extinction is a clear sign of serious problems in the region. In Salmon Without Rivers, fisheries biologist Jim Lichatowich offers an eye-opening look at the roots and evolution of the salmon crisis in the Pacific Northwest. He describes the multitude of factors over the past century and a half that have led to the salmon's decline, and examines in depth the abject failure of restoration efforts that have focused almost exclusively on hatcheries to return salmon stocks to healthy levels without addressing the underlying causes of the decline. The book: describes the evolutionary history of the salmon along with the geologic history of the Pacific Northwest over the past 40 million years considers the indigenous cultures of the region, and the emergence of salmon-based economies that survived for thousands of years examines the rapid transformation of the region following the arrival of Europeans presents the history of efforts to protect and restore the salmon offers a critical assessment of why restoration efforts have failed Throughout, Lichatowich argues that the dominant worldview of our society -- a worldview that denies connections between humans and the natural world -- has created the conflict and controversy that characterize the recent history of salmon; unless that worldview is challenged and changed, there is little hope for recovery. Salmon Without Rivers exposes the myths that have guided recent human-salmon interactions. It clearly explains the difficult choices facing the citizens of the region, and provides unique insight into one of the most tragic chapters in our nation's environmental history.

Available in PDF, EPUB and Kindle. Book excerpt: CLICK HERE to download the first chapter from A Long Treak Home * Compelling adventure with an environmental focus * An informative natural and cultural history of one of our last wild coastlines * Author is a pioneer in "packrafting," an emerging trend in backcountry travel In June 2007, Erin McKittrick and her husband, Hig, embarked on a 4,000-mile expedition from Seattle to the Aleutian Islands, traveling solely by human power. This is the story of their unprecedented trek along the northwestern edge of the Pacific Ocean-a year-long journey through some of the most rugged terrain in the world- and their encounters with rain, wind, blizzards, bears, and their own emotional and spiritual demons. Erin and Hig set out from Seattle with a desire to raise awareness of natural resource and conservation issues along their route: clear-cut logging of rainforests; declining wild salmon populations; extraction of mineral resources; and effects of global climate change. By taking each mile step by step, they were able to intimately explore the coastal regions of Washington, British Columbia, and Alaska, see the wilderness in its larger context, and provide a unique on-the-ground perspective. An entertaining and, at times, thrilling adventure, theirs is a journey of discovery and of insights about the tiny communities that dot this wild coast, as well as the individuals there whom they meet and inspire.

Download or read book Salmon People and Place written by Jim Lichatowich and published by . This book was released on 2013 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Each year wild Pacific salmon leave their oceanic feeding grounds and swim hundreds of miles back to their home rivers. The salmon's annual return is a place-defining event in the Pacific Northwest, with immense ecological, economic, and social significance. However, despite massive spending, efforts to significantly alter the endangered status of salmon have failed. In Salmon, People, and Place, acclaimed fisheries biologist Jim Lichatowich eloquently exposes the misconceptions underlying salmon management and recovery programs that have fueled the catastrophic decline in Northwest salmon populations for more than a century. These programs will continue to fail, he suggests, so long as they regard salmon as products and ignore their essential relationship with their habitat. But Lichatowich offers hope. In Salmon, People, and Place he presents a concrete plan for salmon recovery, one based on the myriad lessons learned from past mistakes. What is needed to successfully restore salmon, Lichatowich states, is an acute commitment to healing the relationships among salmon, people, and place. A significant contribution to the literature on Pacific salmon, Salmon, People, and Place: A Biologist's Search for Salmon Recovery is an essential read for anyone concerned about the fate of this Pacific Northwest icon.

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.
