Available in PDF, EPUB and Kindle. Book excerpt: "By examining a suite of over 90 indicators for nine major U.S. fishery ecosystem jurisdictions, Link and Marshak systematically track the progress the U.S. has made toward advancing ecosystem-based fisheries management (EBFM) and making it an operational reality. Covering a range of socioeconomic, governance, environmental forcing, major pressures, systems ecology, and fisheries criteria, they evaluate progress toward EBFM in the U.S., covering a wide range of longitude, latitude, and parts of major ocean basins, representing over 10% of the world’s ocean surface area. They view progress toward the implementation of EBFM as synonymous with improved management of living marine resources in general, and highlight lessons learned from a national perspective. Although US-centric, the lessons learned are applicable for all parts of the global ocean. Though much work remains, significant progress has been made to better address many of the challenges facing the sustainable management of our living marine resources"--Publisher's description.

Features: Written by twenty-four teams of leading scientists and managers. Promotes transparent justification for fishing and hunting regulations. Provides examples for integrating decision making into management. Emphasizes creativity in management by integrating art and science. This book appeals to population biologists, evolutionary biologists and social scientists. It is a key resource for on-the-ground managers and research scientists developing harvesting applications. As the book’s contributors explain: “Making decisions that are robust to uncertainty...is a paradigm shift with a lot of potential to improve outcomes for fish and wildlife populations.” –Andrew Tyre and Brigitte Tenhumberg “Temporal shifts in system states...must somehow be anticipated and dealt with to derive harvest policies that remain optimal in the long term.” –Michael Conroy “Proactive, effective management of sportspersons...will be essential in the new paradigm of harvest management.” –Matthew Gruntorad and Christopher Chizinski
Download or read book Blood Types in Pacific Salmon written by George J. Ridgway and published by . This book was released on 1960 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intraspecific differences in erythrocyte antigens (blood types) were shown to occur in four species of Pacific salmon, the sockeye or red salmon (Oncorhynchus nerka), the chinook or king salmon (O. tshawytscha), the chum salmon (O. keta), and the pink salmon (O. gorbuscha). Antisalmon-erythrocyte sera prepared in rabbits and chickens were used after absorption of species-specific antibodies. Some of these blood types were shown to differ in their frequency of occurrence between different geographic races. In addition, isoimmunizations were prepared and at least eight different patterns of antigenic composition were displayed by the cells tested. These results indicate that considerable antigenic diversity exists in salmon. Reagents to detect valuable markers for the investigation of geographic races of salmon should be obtained through further research.

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.

Download or read book Wildlife Ecology and Management in Mexico written by Raul Valdez and published by Texas A&M University Press. This book was released on 2019-01-23 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mexico is the fourteenth largest country in the world and ranks fifth in biodiversity. Located in the transition zone between the temperate and tropical regions of North and South America, Mexico is an important migratory corridor for wildlife and also provides wintering habitat for several species of bats, monarch butterflies, and temperate North American nesting birds. Mexico faces several challenges to wildlife management and conservation efforts. While there is increased public education and acknowledgment of the valuable benefits wildlife provides, there is still much work to do to incentivize conservation efforts. Fortunately, there is growing recognition that Mexico’s wildlife resources can be a critical component in the rural economic development of the country. Bringing together an international team of wildlife experts across North America, Wildlife Ecology and Management in Mexico provides information on the status, distribution, ecological relationships, and habitat requirements and management of the most important game birds and mammals in Mexico. It also reviews current threats and challenges facing wildlife conservation as well as strategies for resolving these issues. This reference is a valuable tool for wildlife biologists, wildlife management professionals, and anyone interested in conserving Mexico’s wealth of natural resources. By laying out the challenges to conservation research, editors Raul Valdez and J. Alfonso Ortega-S. hope to encourage interdisciplinary communication and collaboration across borders.
