"Phytoplankton species competition related to individual extracellular phosphatase activities was studied in the eutrophic \u0158\u00EDmov reservoir during an in situ experiment. A natural phytoplankton assemblage was enclosed in permeable dialysis bags inside two containers of different phosphate concentrations. Total and cell-associated phosphatase activities were investigated using the ELF technique that allows for direct microscopic detection and, with image cytometry, enables its quantification. Phytoplankton species produced extracellular phosphatases less often in the phosphate-enriched environment and their specific growth rates were higher than growth rates in the phosphate-depleted environment within those populations that were phosphatase-positive." .
