The composition of epipelic algal assemblages changed over time in both higher taxonomic groupings and species representations. September month was characterised by a dominance of Navicula hungarica var. capitata. The occurrence of diatom species also correlated with water temperature. However, although the growth of some species was restricted to a particular month, other species or species complexes had more extended growth periods. Navicula cryptocephala and Amphora ovalis species have been selected to demonstrate variation in temporal distribution within species complexes. 收起
