The PELAG 1996 Symposium Proceedings provides the reader with the latest advances in the study of planktonic cycling of matter and energy, placing a strong emphasis on the effects of eutrophication on these processes. This book covers a wide range of topics in the field, including:

• Nutrient limitation of phytoplankton growth
• Nutrient cycles in the planktonic food web
• DOM sources, composition, and uptake
• Resource limitation vs. shaping of the food web by grazing
• Spatio-temporal variability: coupling of physical and biological processes
• Processes controlling sinking losses from the pelagic system
• Planktonic food web modelling

.
The book should be of interest to everybody involved in planktonic ecosystem research, from the advanced student to the distinguished scientist. This volume brings to the reader the expertise of internationally renowned authors on the main issues of today's ecological plankton research.

• Eutrophication
• Sediment
• ecosystem
• ecosystems
• environment
• mesocosm
• mesocosms
• phytoplankton
• plankton
• zooplankton

`In summary, this book should be of interest to many researchers. Even though most contributions have a fundamental science background, it could be of use to water managers, and others working in the applied end of the scientific spectrum as well.'
Archiv für Hydrobiologie, 145:2 (1999)
`... the present book offers a valuable contribution to our understanding of planktonic ecology, and can be recommended for both the student and the `expert'. The four introductory chapters offer the general insight, and among the remaining case-studies and experiments there is something of interest for any scientist and manager in the field.'
