Abstract
No previous study of plankton in lakes has estimated the relative contribution of ciliated protozoa to the biomass of the total plankton community, including phytoplankton. In a series of south-central Ontario lakes, ciliates comprise on the order of 5 to 10% of the total planktonic biomass of these relatively oligotrophic lakes and exist there in densities of 20–40 ml−1. Therefore, ciliates constitute an important component of lake ecosystems that should not be ignored in limnological studies of zooplankton abundance and distribution.
