Ecology of Marine Deposit Feeders [Paperback]

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.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.
