This multidisciplinary volume comprehensively reviews our current knowledge of the effects of urban, industrial and agricultural pollution on the biology of shallow coastal marine lagoons. All the authors are internationally recognized authorities and have had many years of experience in their respective fields. The major strength of this volume is that it integrates several fields of research including biogeochemistry, marine microbiology, marine algology and marine zoology. By adopting such a strategy the reader is provided with a clear insight of the key processes involved in lagoon eutrophication and dystrophy and their impact on the different biological communities which live in such environments. This book will therefore provide an essential reference work for environmental biologists, ecologists, microbiologists and those involved in the management and commercial exploitation of these economically important ecosystems.
