Levinton’s Marine Biology is highly acclaimed and regarded by many as the best, most authoritative text for the sophomore/junior/senior marine biology course. The text is characterized by its exceptionally clear and conversational writing style, comprehensive coverage, and sophisticated presentation featuring organismal and ecosystem ecology topics from an evolutionary perspective. Over the course of five editions, Jeff Levinton has balanced his organismal and ecological focus by including the latest developments from the world of molecular biology, global climate change, and oceanic processes.
