Available in PDF, EPUB and Kindle. Book excerpt: Tracks recent environ. changes throughout the Arctic. In 2010, it is clear that the Arctic is experiencing the impacts of a prolonged and amplified warming trend, highlighted with many record-setting events. The impact of this warming is most evident in the dramatic losses that have been observed in the ice covers that define the region. Since the loss of these ice covers serves to further feed the warming trend, the expectation is that warming will continue. This makes it increasingly unlikely that the Arctic will return to conditions that were considered normal in the later part of the 20th cent. Instead, it is very likely that Arctic climate warming will continue and records will continue to be set in years to come. Charts and tables. This is a print on demand report.
Download or read book Long term Ecological Change in the Northern Gulf of Alaska written by R.B. Spies and published by Elsevier. This book was released on 2006-12-12 with total page 609 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive text is a major synthesis on ecological change in the Gulf of Alaska. It encompasses the structural and annual changes, forces of change, long-ecological changes in the atmosphere and ocean, plankton, fish, birds and mammals, and the effects of the 1989 Exxon Valdez Oil Spill. With 5 major sections, Long-term Ecological Change in the Northern Gulf of Alaska first describes the physical features, the atmosphere and physical oceanography, the annual production cycle, the forage base for higher animals and trophic transfer, and the adaptations for survival in this changing environment for 9 portal species. Then, the major forces of change are introduced: climate, geophysics, fisheries and harvesting, species interactions, disease and contaminants. Next, the long-term records of change in physical factors and biological populations are presented, as well as the potential reasons for the biological changes. Following is the history of the Exxon Valdez oil spill and its long-term effects. And, finally, the emergent properties of the ecosystem are discussed and an attempt is made to weigh the importance of the major forcing factors in terms of their temporal and spatial scales of influence.* Examines important data on long-term change in the ecosystem and the forcing factors that are responsible for it * Provides an account of the 1989 Exxon Valdez oil spill with emphasis on the long-term effects * Describes the effects of climate change, geophysical change, species interactions, harvesting, disease, the 1989 oil spill, and marine contaminants on key populations of marine organisms

Download or read book Return to Wild America written by Scott Weidensaul and published by Macmillan + ORM. This book was released on 2006-10-31 with total page 557 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1953, birding guru Roger Tory Peterson and noted British naturalist James Fisher set out on what became a legendary journey-a one hundred day trek over 30,000 miles around North America. They traveled from Newfoundland to Florida, deep into the heart of Mexico, through the Southwest, the Pacific Northwest, and into Alaska's Pribilof Islands. Two years later, Wild America, their classic account of the trip, was published. On the eve of that book's fiftieth anniversary, naturalist Scott Weidensaul retraces Peterson and Fisher's steps to tell the story of wild America today. How has the continent's natural landscape changed over the past fifty years? How have the wildlife, the rivers, and the rugged, untouched terrain fared? The journey takes Weidensaul to the coastal communities of Newfoundland, where he examines the devastating impact of the Atlantic cod fishery's collapse on the ecosystem; to Florida, where he charts the virtual extinction of the great wading bird colonies that Peterson and Fisher once documented; to the Mexican tropics of Xilitla, which have become a growing center of ecotourism since Fisher and Peterson's exposition. And perhaps most surprising of all, Weidensaul finds that much of what Peterson and Fisher discovered remains untouched by the industrial developments of the last fifty years. Poised to become a classic in its own right, Return to Wild America is a sweeping survey of the natural soul of North America today.
Download or read book Decline of the Steller Sea Lion in Alaskan Waters written by National Research Council and published by National Academies Press. This book was released on 2003-04-04 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: For an unknown reason, the Steller sea lion population in Alaska has declined by 80% over the past three decades. In 2001, the National Research Council began a study to assess the many hypotheses proposed to explain the sea lion decline including insufficient food due to fishing or the late 1970s climate/regime shift, a disease epidemic, pollution, illegal shooting, subsistence harvest, and predation by killer whales or sharks. The report's analysis indicates that the population decline cannot be explained only by a decreased availability of food; hence other factors, such as predation and illegal shooting, deserve further study. The report recommends a management strategy that could help determine the impact of fisheries on sea lion survival-establishing open and closed fishing areas around sea lion rookeries. This strategy would allow researchers to study sea lions in relatively controlled, contrasting environments. Experimental area closures will help fill some short-term data gaps, but long-term monitoring will be required to understand why sea lions are at a fraction of their former abundance.
