Název v původním jazyce

Longitudinal changes in protistan bacterivory and bacterial production in two canyon-shaped reservoirs of different trophic status.

Popis výsledku v původním jazyce

We studied bacterial production and mortality due to heterotrophic nanoflagellate and ciliate grazing on longitudinal transects conducted on two reservoirs, Římov and Orlík. Special attention was paid to the changes in these processes related to depth, spatial distribution of sampling points, different periods of planktonic succession and to the taxon-specific bacterivory of ciliates. In Římov, when seasonally averaged, total protistan grazing accounted for 35% of BP and was consistantly lower in the layer R (layer with the same temperature and conductivity as the river inflow). On contrary, the seasonal average for Orlík showed roughly two times higher proportion of BP (70% of the total) removed by protists. Oligotrichous ciliates were recognized as the major ciliate bacterivores (accounting for 67% and 48% of total ciliate bacterivory in Římov and Orlík, respectively) followed by peritrichous ciliates that contributed to total ciliate bacterivory from 23% (Římov) to 28% (Orlík).
