Book Description
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

Book Description
When the Exxon Valdez oil tanker ran aground on Bligh Reef in Alaska in 1989 and spilled 11 million gallons of oil, it changed Prince William Sound forever. The catastrophe disrupted the region’s biological system, killing countless animals and poisoning habitats that to this day no longer support some of the local species. The effects have also profoundly altered the way people use this region. Nearly three decades later, changes in recreation use run counter to what was initially expected. Instead of avoiding Prince William Sound, tourists and visitors flock there. Economic revitalization efforts have resulted in increased wilderness access as new commercial enterprises offer nature tourism in remote bays and fjords. This increased visitation has caused concerns that the wilderness may again be threatened—not by oil but rather by the very humans seeking those wilderness experiences. In Sustaining Wildlands, scientists and managers, along with local community residents, address what has come to be a central paradox in public lands management: the need to accommodate increasing human use while reducing the environmental impact of those activities. This volume draws on diverse efforts and perspectives to dissect this paradox, offering an alternative approach where human use is central to sustaining wildlands and recovering a damaged ecosystem like Prince William Sound.

Book Description
Completely revised and updated with 18 new chapters, this second edition includes contributions from over 75 international experts. Also, a Technical Review Board reviewed all manuscripts for accuracy and currency. Focusing on toxic substance and how they affect the ecosystems worldwide, the book presents methods for quantifying and measuring ecotoxicological effects in the field and in the lab, as well as methods for estimating, predicting, and modeling in ecotoxicology studies. This is the definitive reference for students, researchers, consultants, and other professionals in the environmental sciences, toxicology, chemistry, biology, and ecology - in academia, industry, and government.
