. "An experiment designed to examine food preferences of heterotrophic nanoflagellates grazing on bacterioplankton was performed in the freshwater \u0158\u00EDmov reservoir. Water samples were size-fractionated to obtain <5um filtrate containing bacteria and HNF. To manipulate resource availability,<5um treatments were incubated in dialysis bags submerged in the barrels filled with the unfiltered reservoir water amended with either orthophosphate or glucose or combination of both. We employed r-RNA-targeted probes to assess HNF prey preferences by analyzing bacterial prey in HNF food vacuoles compared to available bacteria. Actinobacteria were avoided by HNF in all treatments. Cytophaga-Flavobacterium-Bacteroidetes bacteria were positively selected mainly in treatments in which bacteria were heavily grazed,the <5um treatments, but this trend was less pronounced towards the end of the study. The members of a small subcluster of Betaproteobacteria were mostly positively selected."@en . .
