Anotace	We investigated the linkages between the composition and the activities of bacterioplankton assemblages in three stations (Dam, Middle, River) in the meso-eutrophic Římov reservoir (Czech Republic). At all stations, Betaproteobacteria (BET) or Actinobacteria (ACT) dominated the bacterial community composition, while Cytophaga-Flavobacteria (CF) accounted for smaller proportions. ACT showed high proportions of cells incorporating both leucine and glucose in all samples, whereas only small fractions of CF were scored positive for the incorporation of these substrates. BET incorporated leucine preferentially to glucose in all samples. Interestingly, CF and BET significantly contributed to the pool of high nucleic acid cells (HNA) at Stn River, whereas the opposite was found for ACT, forming the pool of low nucleic acid cells (LNA) at all stations. Since ACT efficiently incorporated organic substrates, the LNA fraction represented a highly active component of bacterial assemblages.
