Summary
Summary
The sustainable exploitation of the marine environment depends upon our capacity to develop systems of management with predictable outcomes. Unfortunately, marine ecosystems are highly dynamic and this property could conflict with the objective of sustainable exploitation. This book investigates the theory that the population and behavioural dynamics of predators at the upper end of marine food chains can be used to assist with management. Since these species integrate the dynamics of marine ecosystems across a wide range of spatial and temporal scales, they offer new sources of information that can be formally used in setting management objectives. This book examines the current advances in the understanding of the ecology of marine predators and will investigate how information from these species could be used in management.

Choice Review
This work is a product of an international symposium drawing on research focused on marine systems in high latitudes. Contributed papers attempt to link changes in physical oceanography to ecosystem responses; assess the efficacy of using monitoring studies of predator populations to follow ecosystem changes; and discuss competing rationales for managing ecosystems to maintain top predators. The editors have done a commendable job in maintaining a consistent look and level of quality among the papers. Unfortunately, the title overreaches. The studies focus almost solely on the ecology of marine birds and mammals occurring in cold water systems. The absence of comparable information on top fish and invertebrate predators in all marine systems, especially in warm water systems, means that this volume's results cannot be generalized to all marine environments. However, the conclusions reached in many of the papers will serve as hypotheses to be tested in temperate and tropical marine waters. The style of the papers is standard scientific-journal format that will be useful almost exclusively to graduate students and researchers. ^BSumming Up: Recommended.
