diatom valves was observed. Their very low frequency and the poor state of preser-
vation indicate the intensification of chemical dissolution processes and mechanical
fragmentation. The diatom community in the sample at 11-16 cm in core 345580
was also poorly preserved, but quite abundant and represented by diverse taxons
Two ecological groups among the predominant benthic freshwater diatoms can
be distinguished:
