The reservoirs showed specific longitudinal changes in plankton communities and BCC shifts. In Orlík reservoir, primary production, bacterial abundance, bacterial production and protozoan bacterivory showed consistant trend of a gradual decrease from the river inflow downstream to the reservoir dam. Shifts in BCC were statistically insignificant. In contrast, the Římov reservoir has a long retention time and its lacustrine area had a limited input of allochthonous organic matter. In Římov the autochthonous processes of primary and bacterial productions were tightly linked and they showed peaks in the middle part of the reservoir. This together with a trend of downstream decreasing nutrient concentrations and increasing protistan grazing pressure seem to support the development of specific BCC in the lacustrine part.
