Phytoplankton cell size structure can provide information on the successive levels of consumers and therefore on the energy that can flow towards the top consumers.

The inter-annual and seasonal dynamics of picophytoplankton (Pico, cell size <3 \u03bcm) and Uterm\u00f6hl Fraction of Phytoplankton (UFP, cell size >3 \u03bcm) were considered during almost three years in relation to the temporal dynamics of selected environmental variables and zooplankton.

Picocyanobacteria rich in phycocyanin were the dominant taxa of Pico along the entire investigation period and this size class contributed the most to total phytoplankton biomass (up to 30%) and density (up to 96%) at the end of the study. The observed shift towards different and even smaller UFP and Pico in the second part of the study was most probably due to complex interactions between top-down and bottom-up effects.
