Diatoms from a peat bog on the Pešter plateau (southwestern Serbia): New records for diatom flora of Serbia

Abstract

The distribution of diatoms was studied in three types of diatom communities (epiphytes, benthos and plankton) of a peat bog on the Pešter plateau. The observed diatom flora inhabited all investigated communities, comprising in total 250 taxa in 53 genera. Among them, 45 taxa were new records for the Serbian diatom flora. Identified taxa belonged to different groups of algae, however alkaliphile diatoms were dominant. New ecological data for Encyonopsis minuta, Pinnularia isostauron and P. marchica are presented here. All the diatoms were documented by light micrographs, and brief notes on their morphology, distribution and ecology are provided.
