INTRODUCTION TO MARINE BIOLOGY distinguishes itself from other texts at this introductory level by taking an ecological approach to the study of marine biology, by providing succinct coverage of key topics, and through the use of the best illustrations and photos currently available. In this edition two co-authors have joined George Karleskint?James Small from Rollins College in Winter Park, Florida, and Richard Turner from the Florida Institute of Technology. Their experience in coastal environments nicely compliments Karleskint's clear, concise student-friendly writing style. Users will also discover that the level of the text has been broadened with additional coverage of plant, microbial, planktonic, and animal biology. In support of this emphasis, new "In Perspective" summary tables have been added to each of the marine organism chapters to provide a summary of important ecological and biological aspects of various marine organisms. Even with this broadened emphasis, this edition of INTRODUCTION TO MARINE BIOLOGY remains exceptionally readable. The textual material has been broken into small paragraph sections with more headings for ease of navigation, and "In Summary" statements have been added to the end of each main heading within the chapter, making it easy for students to check their understanding before reaching the end of the chapter. Furthermore, the authors have added more words to the glossary, many new illustrations, and over one hundred new photos. This second edition also boasts an increased "ecological focus" through the addition of discussions on "ecological roles and relationships."George Karleskint is the author of 'Introduction to Marine Biology (with InfoTrac)', published 2005 under ISBN 9780534420727 and ISBN 0534420729.
