Spatial heterogeneity of diatom silicification and growth in a eutrophic reservoir

Original language description

Diatoms represent one of the most important phytoplankton groups. As they grow, diatoms use silicon to produce a siliceous frustule, which protects the cell. In April? November 2011, at 1?3 weeks intervals, we estimated diatom silification rates at two distinct sites along the longitudinal profile of the canyon-shaped eutrophic Římov Reservoir (Czech Republic): (i) a nutrient-depleted lacustrine zone near the dam and (ii) a nutrient-rich transition zone upstream near the river inflow. Diatom silification was estimated using the 24?hour in situ incubation of natural phytoplankton assemblage with a fluorophore 2-(4-pyridyl)-5-{[4-(2-dimethylaminoethyl-aminocarbamoyl)methoxy]phenyl}oxazole (PDMPO) which fluorescently stains the newly synthesized diatom frustules. In the lacustrine zone, diatoms contributed on the average cca 40 % to the total phytoplankton biovolume but only cca 20 % in the transition zone where cyanobacterial bloom developed during summer.
