Download or read book Managed Annihilation written by Dean Bavington and published by UBC Press. This book was released on 2011-01-01 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Newfoundland and Labrador cod fishery was once the most successful commercial fishery in the world. When it collapsed in 1992, many pointed to failures in management, such as uncontrolled harvesting, as likely culprits. Managed Annihilation makes the case that the idea of natural resource management itself was the problem. The collapse occurred when the fisheries were state-managed and still, two decades later, there is no recovery in sight. Although the collapse raised doubts among policy-makers about their ability to understand and control nature, their ultimate goal of control through management has not wavered and has been transferred from wild fish to fishermen and farmed cod.
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.

Download or read book Metabolism of Polycyclic Aromatic Hydrocarbons in the Aquatic Environment written by Usha Varanasi and published by CRC Press. This book was released on 1989-03-31 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book shows how the biological transport, bioaccumulation, disposition, and toxicity of polycyclic aromatic hydrocarbons (PAH) in the aquatic environment are influenced by the ability or inability of organisms to metabolize these environmental pollutants. Written by leading scientists in the fields of PAH metabolism and toxicity in both aquatic and mammalian systems, this book discusses recent advances in the areas of PAH biogeochemistry and bioaccumulation, microbial degradation, enzymes of activation, and detoxication, metabolism of PAH, and laboratory and field studies on carcinogenic/toxic effects. Additionally, important similarities and differences in metabolism of PAH by aquatic and terrestrial organisms are featured. The discussion of bioavailability, metabolism, and subsequent toxic effects should aid in the assessment of the ecological consequences of PAH in the aquatic environment.
Download or read book The Last Landscape written by William H. Whyte and published by University of Pennsylvania Press. This book was released on 2012-10-23 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: The remaining corner of an old farm, unclaimed by developers. The brook squeezed between housing plans. Abandoned railroad lines. The stand of woods along an expanded highway. These are the outposts of what was once a larger pattern of forests and farms, the "last landscape." According to William H. Whyte, the place to work out the problems of our metropolitan areas is within those areas, not outside them. The age of unchecked expansion without consequence is over, but where there is waste and neglect there is opportunity. Our cities and suburbs are not jammed; they just look that way. There are in fact plenty of ways to use this existing space to the benefit of the community, and The Last Landscape provides a practical and timeless framework for making informed decisions about its use. Called "the best study available on the problems of open space" by the New York Times when it first appeared in 1968, The Last Landscape introduced many cornerstone ideas for land conservation, urging all of us to make better use of the land that has survived amid suburban sprawl. Whyte's pioneering work on easements led to the passage of major open space statutes in many states, and his argument for using and linking green spaces, however small the areas may be, is a recommendation that has more currency today than ever before.
Download or read book Wetland Carbon and Environmental Management written by Ken W. Krauss and published by John Wiley & Sons. This book was released on 2021-11-23 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explores how the management of wetlands can influence carbon storage and fluxes. Wetlands are vital natural assets, including their ability to take-up atmospheric carbon and restrict subsequent carbon loss to facilitate long-term storage. They can be deliberately managed to provide a natural solution to mitigate climate change, as well as to help offset direct losses of wetlands from various land-use changes and natural drivers. Wetland Carbon and Environmental Management presents a collection of wetland research studies from around the world to demonstrate how environmental management can improve carbon sequestration while enhancing wetland health and function. Volume highlights include: Overview of carbon storage in the landscape Introduction to wetland management practices Comparisons of natural, managed, and converted wetlands Impact of wetland management on carbon storage or loss Techniques for scientific assessment of wetland carbon processes Case studies covering tropical, coastal, inland, and northern wetlands Primer for carbon offset trading programs and how wetlands might contribute The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity.Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

Download or read book The Ad lie Penguin written by David Ainley and published by Columbia University Press. This book was released on 2002-10-01 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Adélie penguin is one of the best-studied birds in the world and is the subject of research programs from a dozen nations interested in monitoring changes in the environment and the food webs of the Southern Ocean. This species' population has been changing dramatically over the past few decades coincident with a general warming of the maritime portion of Antarctica. When the sea-ice is seen to decline so does the population of Adélie penguins. Further south, however, the population is increasing. This book summarizes our present ecological knowledge of this polar seabird. In so doing, David Ainley describes the ecological factors important to its life history and details the mechanisms by which it is responding to climate change. The author also chronicles the history of research on Adélie penguins, beginning with the heroic expeditions at the beginning of the twentieth century. Weaving together history, ecology, natural history, and written accounts from the earliest Antarctic naturalists into a fascinating account of this charismatic bird, The Adélie Penguin provides a foundation upon which future ornithological research and environmental monitoring can be based. It is a model for investigations into the effect of climate change on a particular species. The book also contains many fine illustrations from the accomplished illustrator Lucia deLeiris and photographs by the author.

Download or read book The Mortal Sea written by W. Jeffrey Bolster and published by Harvard University Press. This book was released on 2012-10-08 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the Viking ascendancy in the Middle Ages, the Atlantic has shaped the lives of people who depend upon it for survival. And just as surely, people have shaped the Atlantic. In his innovative account of this interdependency, W. Jeffrey Bolster, a historian and professional seafarer, takes us through a millennium-long environmental history of our impact on one of the largest ecosystems in the world. While overfishing is often thought of as a contemporary problem, Bolster reveals that humans were transforming the sea long before factory trawlers turned fishing from a handliner's art into an industrial enterprise. The western Atlantic's legendary fishing banks, stretching from Cape Cod to Newfoundland, have attracted fishermen for more than five hundred years. Bolster follows the effects of this siren's song from its medieval European origins to the advent of industrialized fishing in American waters at the beginning of the twentieth century. Blending marine biology, ecological insight, and a remarkable cast of characters, from notable explorers to scientists to an army of unknown fishermen, Bolster tells a story that is both ecological and human: the prelude to an environmental disaster. Over generations, harvesters created a quiet catastrophe as the sea could no longer renew itself. Bolster writes in the hope that the intimate relationship humans have long had with the ocean, and the species that live within it, can be restored for future generations.
