Download or read book Reef Fish Spawning Aggregations Biology Research and Management written by Yvonne Sadovy de Mitcheson and published by Springer Science & Business Media. This book was released on 2011-12-10 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reef fish spawning aggregations, ranging from small groups to many tens of thousands of individuals, are spectacular but poorly known natural phenomena whereby fish assemble at specific times and locations to spawn. For some species these large groups may be the only form of reproduction, the high fish numbers briefly giving a false impression of stability and abundance—an ‘illusion of plenty’. They are often a focus for intensive seasonal fishing because of their predictability and because many important commercial fishes form them. Highly vulnerable to overexploitation, many aggregations and their associated fisheries, have disappeared or are in decline. Few are effectively managed or incorporated into protected areas. Aggregations are not well understood by fishery scientists, managers and conservationists and their significance little appreciated by fishers or the wider public. To ensure their persistence to replenish important fisheries in coral ecosystems, maintain their ecosystem function and continue to delight divers, a significant change in perspective is needed to foster protection and management. This book provides comprehensive and practical coverage of the biology, study and management of reef fish aggregations, exploring their how, when, where, and why. It explores ways to better protect, study, manage and conserve them, while identifying key data gaps and questions. The text is extensively illustrated with many unique, never before published, photographs and graphics. Case studies on over 20 interesting and important fishes are included, outlining their biology and fisheries and highlighting major concerns and challenges.

Download or read book The Bering Sea Ecosystem written by National Research Council and published by National Academies Press. This book was released on 1996-05-08 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Bering Sea, which lies between the United States and Russia, is one of the most productive ecosystems in the world and has prolific fishing grounds. Yet there have been significant unexplained population fluctuations in marine mammals and birds in the region. The book examines the Bering Sea ecosystem's dynamics and the relationship between man and the ecosystem, in order to identify potential reasons for the population fluctuations as well as identify ways the Sea's living resources can be better managed by government.

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.

Book excerpt: The oil spill disaster that occurred when the Exxon Valdez ran aground has become part of the iconography of ecological disaster. This book synthesizes confidential data, recently released by the US government, concerning the effects of this spill on marine mammals (ie. sea otters, harbour seals, killer whales and humpback whales). Many of the contributors were on site within 24 hours of the spill and their results establish a baseline worst case scenario. These data should assist marine biologists, pathologists, toxicologists, environmentatlists, engineers, and coastal planners in assessing the nature of this disaster.

Download or read book Walking Dena ina written by Douglas Deur and published by . This book was released on 2021-02-04 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume describes Telaquana Trail, an ancient pathway ascending from the shores of Qizhjeh Vena, Lake Clark, through tundra and timbered valleys, into a high-elevation expanse of rolling tundra and smaller interior lakes nearly 50 miles north of Lake Clark. The pathway is an ancestral corridor used by Native peoples since the beginning of remembered time. The name "Telaquana Trail" first appears in the written record by no later than 1921, when Colonel A.J. Macnab, one of the first outsiders to visit the area for recreational big game hunting, mentioned taking a canoe to "go down the lake to look for the Telaquana Trail." Stephen Capps of the U.S. Geological Survey traveled and mapped the area in 1929. Producing the first detailed public map of the trail, Capps marks it as the "Native Route." As Dena'ina interviewees will attest, non-Native travel along the trail by this date was ample, but the corridor was still largely conceived of as Native space. Today, as the traces of significantly Anglo-American mining and trapping communities fade from the landscape, Dena'ina people still look to the trail corridor as a touchstone for their shared history and a cosmological axis of their own unique cultural geography. In the homes of Dena'ina people today, the landmarks of the Telaquana Trail are still remembered and the names of these places still spoken.

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.
