Název v původním jazyce

The effect of extreme rainfall on summer succession and vertical distribution of phytoplankton in a lacustrine part of a eutrophic reservoir

Popis výsledku v původním jazyce

During the summer of 2006, disturbances in the form of dramatic summer storms had a crucial effect on phytoplankton succession and its vertical distribution in the eutrophic Římov Reservoir. Two extreme rainfalls substantially increased flushing rate, yielding a fairly short retention time within the reservoir that disrupted established thermal stratification. The first storm initiated the development of summer phytoplankton, while the second storm reversed the phytoplankton succession to an earlier stage. Biogenic Si deposition studied by PDMPO was measured to compare diatom growth rates over the season. Maximum rates of silica deposition were measured in samples just after both summer storms events. When diatoms dominated the phytoplankton, the amounts of available Si and P in water were significantly correlated (r2 = 0.81, p < 0.001, df = 42). Outliers from the linear relationship were found only during a period when picocyanobacteria developed in the reservoir.
