It covers the trophic, environmental and competitive interactions of marine organisms and the effects of these on the productivity, dynamics and structure of marine systems.

Examples are drawn from all over the world. In this edition, the scientific content of the text has been fully revised and updated. An emphasis has been placed on human impacts and completely new chapters have been added on fisheries, marine ecosystems, and human interference and conservation.
