Using the principles of evolutionary biology and experimental ecology, this course examines the processes that control the diversity, abundance and distribution of marine organisms. Major marine communities, including estuaries, the rocky shore, sandy beaches, salt marshes, coral reefs, and the deep sea are discussed in detail. Format: lectures and laboratories, including coastal and near-shore field trips, 11 days offshore, and a laboratory or field research project. Requirements: an hour test, a research project, a presentation, and a final exam. Prerequisites: Biology 101 and 102 or equivalent or permission of instructor.
