The composition of the dominating populations within a bacterioplankton community was investigated in a mesotrophic, boreal forest lake. Composite samples were collected monthly throughout the lake for two years. The community composition was determined by denaturing gradient gel electrophoresis (DGGE) of a polymerase chain reaction (PCR)‐amplified part of 16S rDNA, extracted from organisms smaller than 1 μm. Temporal patterns of occurrence in the lake differed among populations. There was no clear seasonal pattern of variation, but there was a gradual change. The results suggest that variation in the amount of water flowing into the lake could explain some of the changes in the bacterioplankton community.
