"Microautoradiography was used to study primary production of individual species or genera in two acidified lakes in the Bohemian Forest. Chrysophytes and dinoflagellates were present in both lakes during the studied season, green algae and filamentous cyanobacteria were observed especially in Ple\u0161n\u00E9 Lake. In \u010Certovo Lake, the primary production of Dinobryon pediforme was 38 % of total primary production (PT) at the surface layer and 25 % of PT at the metalimnetic depth. Peridinium umbonatum accounted for 27 % and 31 % of PT at each depth, respectively. In Ple\u0161n\u00E9 Lake, Monoraphidium dybowskii comprised an almost identical portion of PT at both layers (63 %). The photosynthetic activity coefficients (the cell-carbon specific rate of C assimilation) of the mixotrophic bacterivorous Dinobryon was equal or even higher than that of autotrophic species, indicating that it uses ingested bacteria as a source of phosphorus rather than of carbon." .
