Kurzbeschreibung
Due to its sensitivity to ecological change, the benthic environment--a term commonly used to describe the plants and animals living at the bottom of the sea--is becoming a crucial topic in these days of rapid climate change. Originally put together by the International Biological Programme (IBP) in 1971, this popular book on marine benthos is now in its 4th edition. Responding to the ever-increasing demand for data on bottom-living communities, this book provides essential information for those involved in environmental impact statements, pollution assessments, as well as ecosystem management of fisheries.
The continuing global decline of the health of the sea, and the increasing depletion of marine resources and biodiversity, caused by human activity and climate change, have led to ever-increasing international concern. These changes in the marine environment highlight the importance of effective monitoring of the ecology of the benthos which has been shown to be a sensitive index of such alterations.
Completely revised and updated to include many new methods and technologies, this Fourth Edition of Methods for the Study of Marine Benthos provides comprehensive coverage on the tools and techniques available to those working in the area. Commencing with an overview of the design and analysis of benthic surveys, the book continues with chapters covering the sedimentary environment, imaging and diving techniques, macro- and meiofauna techniques, deep sea sampling, energy flow and production. An additional new chapter provided in this edition covers phytobenthos techniques.
Written by many of the world's leading authorities in marine sampling techniques and use, and edited by Professor Anastasios Eleftheriou, this comprehensive Fourth Edition is an essential tool for all marine and environmental scientists, ecologists, fisheries workers and oceanographers. Libraries in all research establishments and universities where these subjects are studied and taught will find this book to be a hugely valuable addition to their collections.
