The subject of marine ecology has moved into an exciting phase where the emphasis in research is on processes and concepts often basic to ecology as a whole. The authors, both experienced teachers of marine ecology, have written a well-illustrated text, now in a revised and up-dated second edition, which reflects the development of the subject and provides a comprehensive yet succinct introduction to a very wide field. The book is principally aimed at undergraduate and first year postgraduates in the biological sciences. 2nd edition, pp. x, 351 illusts, Prev ownership on prelims #0318
