Download or read book Manual for Aging Steelhead Trout Scales Based on Scale Sampling from Sitkoh Creek Big Ratz Creek and Other Southeast Alaska Streams 2003 2011 written by David Champlain Love and published by . This book was released on 2016 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manual documents methods useful for standardized sampling and aging of steelhead trout (Oncorhynchus mykiss) scales in Southeast Alaska. Steelhead trout scale aging can be a subjective process without standardized methods and criteria for aging and known-age samples for comparison; these methods improve precision and accuracy of estimated ages and overall consistency. Methods and criteria based on observed scale morphology were developed from samples of 2,557 scales collected from resident parr, emigrant smolt, and migratory rainbow trout, and also from 2,315 immigrant adult steelhead trout collected from several different locations in Southeast Alaska from 2003 to 2011. Typical scale characteristics used to age steelhead trout include identification of first annulus, interpretation of plus growth, representative circuli counts and fork length criteria for estimating smolt ages, and comparison to morphology from known-aged adult samples. Characteristics of regenerated scales, spawning checks, false checks, and plus-growth useful for interpretation of scale morphology are also discussed. Variable life history of steelhead trout as related to scale morphology is discussed. Steelhead trout juvenile and smolt scale aging methods for freshwater life history include triplicate reads, use of criteria to improve precision, and aging practice from validated smolt scales. Expected scale morphology for the marine portion of adult steelhead trout scales collected from known ocean-age fish is presented. Methods for evaluating scale aging consistency through testing within-reader precision (repeatability), and between-reader relative accuracy are suggested. Annotated images of representative scale samples from parr, smolt, and adult steelhead trout are provided for reference as is a list of known-age, or matching-age scale, images to be used for training. Standardizing protocols and criteria used to age Southeast Alaska steelhead trout scales along with methods to evaluate technician performance are suggested as a means to ensure consistency and continuity in aging methods for future scale aging of steelhead trout in Southeast Alaska.

Book excerpt: This is the first detailed analysis of a completely excavated northern Iroquoian community, a sixteenth-century ancestral Wendat village on the north shore of Lake Ontario. The site resulted from the coalescence of multiple small villages into one well-planned and well-integrated community. Jennifer Birch and Ronald F. Williamson frame the development of this community in the context of a historical sequence of site relocations. The social processes that led to its formation, the political and economic lives of its inhabitants, and their relationships to other populations in northeastern North America are explored using multiple scales of analysis. This book is key for those interested in the history and archaeology of eastern North America, the social, political, and economic organization of Iroquoian societies, the archaeology of communities, and processes of settlement aggregation.

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.
Download or read book Roadside Geology of Alaska written by Cathy Connor and published by Mountain Press. This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The biggest US state is full of superlatives. Denali, the highest peak in North America at 20,320 feet, is still rising, pushed upward as a tectonic plate collides from the south. The collision has also created huge mountains along Alaska�s Gulf Coast, where humid coastal air has produced the largest subpolar icefield in North America. The exceptional heights of Alaska�s mountains are mirrored below sea level by the 22,377-foot-deep trench of the active subduction zone along Alaska�s southern shore. Earthquakes associated with the subduction zone shake Alaskans frequently, and the magnitude 9.2 earthquake in 1964, with its epicenter in Prince William Sound, was one of the largest seismic events ever recorded. Such an active geologic setting calls for an updated edition of this popular roadside geology guide. Since the first edition was published in 1988, volcanoes have erupted, faults have ruptured, glaciers have retreated, permafrost has thawed, and geologic interpretations have changed. Author Cathy Connor discusses the latest findings as she guides readers along the roads of Alaska and adjacent parts of British Columbia and the Yukon. In addition to roads and national parks, the book covers the �boatside geology� of Alaska, including the fjords of southeast Alaska, islands in the Bering Sea, and the Tatshenshini River. Roadside Geology of Alaska is a must-have for any Alaska rock enthusiast.
