"This textbook is organized into three parts. The first explores processes that generate pattern in benthic communities. The middle examines the ecology of specific marine benthic community types, ranging from rocky shores and soft substrate habitats to kelp forests and coral reefs. The close examines conservation and management issues, emphasizing how profoundly marine communities are impacted by humans"--

"With its clear and conversational writing style, comprehensive coverage, and sophisticated presentation, "Marine Biology: Function, Biodiversity, Ecology", Sixth Edition, is regarded by many as the most authoritative marine biology text. Over the course of six editions, Jeffrey Levinton has balanced his organismal and ecological focus by including the latest developments on molecular biology, global climate change, and ocean processes"

Deposit feeders, animals that derive nutrition from organic matter in sedimentary deposits, are dominant among the inhabitants of muds and, therefore, of the benthos of much of the ocean. In this volume the critical research problems pertaining to deposit feeders are identified and promising approaches for dealing with those problems are proposed. Interdisciplinary approaches are of utmost importance in the study of deposit feeders and their sedimentary environment, merging fields as disparate as nutritional physiology and sediment geochemistry. Among the topics presented are advances in theories of foraging and digestion, and new experimental approaches to study the potential foods, feeding behavior and physiology of animals that ingest sediment
