Název v původním jazyce

Summer changes in cyanobacterial bloom composition and microcystin concentration in eutrophic Czech reservoirs

Popis výsledku v původním jazyce

In mid July and August 2003 and 2004, 18 reservoirs in the Czech Republic were sampled for phytoplankton composition and concentration of intracellular microcystins (MCs). As a consequence of high nutrient loading, most of the reservoirs experienced cyanobacterial blooms of various intensities with the prevalence of cyanobacteria increasing markedly in August, along with a conspicuous shift in species composition towards the dominance of Microcystis Microcystins were detected in 90 % of the samples andtheir amount also increased considerably in August, reflecting the cyanobacterial biomass. In Microcystis dominated samples, significantly higher amount of MCs (p<0.001) occurred than in samples where other taxa prevailed. Microcystins were positively correlated with chlorophyll a and cyanobacterial biovolume (p<0.05) with the strongest correlation found for Microcystis spp. biovolume (p<0.001), this taxon was the most important producer of MCs in Czech reservoirs.
