The papers of the "Second Workshop on the Measurement of Microbial Activity in the Carbon Cycle in Aquatic Ecosystems" reflect the diversity of approaches ranging from molecularbiological and biochemical to the ecosystem level. They were grouped into 7 sections: Uptake of organic and inorganic substances; RNA-and DNA-turnover, Activity regulation; Primary production; Aerobic and anaerobic degradation; Comparison of different methods; Effect of pollution and bioturbation on heterotrophic microbial activity.
