Top Predators in Marine Ecosystems

Herausgeber: Boyd, I. L.; Wanless, S.

• Broschiertes Buch

Produktbeschreibung

Through studying the behaviour and populations of predators in the marine environment, changes in the marine ecosystem can be monitored. As these predators often exploit the same marine resources as fisheries, they can be affected by other human influences on the marine environment and therefore can act as indicators of the impact of man on marine environments. This book examines the current understanding of marine predator ecology and investigates how this information can be used in marine management scenarios.

Autorenporträt

C. J. Camphuysen's current research interests include foraging ecology, mortality and distribution patterns of seabirds in the Atlantic Ocean and in the North Sea, the impacts of fishing on marine birds and the spatial distribution and temporal trends in abundance of cetaceans in the North Sea.
