Figures & Tables

Data for the sampling site in the coastal waters in Sopot as an example of calculations performed for each water body. (A) Mean annual ciliate biomass – weighted mean calculated from seasonal changes in ciliate biomass. (B) Cumulative annual ciliate production – an integral calculated from seasonal changes in ciliate production rates.

Values of mean annual ciliate biomass in surface and near-bottom waters of four lakes and at two stations located in the coastal zone of the southern Baltic Sea. All sampling sites were located in the temperate zone.

Annual production to biomass (P/B) ratios calculated for ciliate communities in surface and near-bottom waters of four lakes and at two stations located in the coastal zone of the southern Baltic Sea. Mean values and standard deviations are noted at the top of the graph.

Distribution of annual ciliate production among the seasons of the year. Calculations were performed separately for surface and near-bottom waters of four lakes and at two stations located in the coastal zone of the southern Baltic Sea. All sampling sites were located in the temperate zone.
