Taxonomic investigation of epilithic diatoms of Lake Hazar (Elazig

In this study, the epilithic diatoms of Lake Hazar, one of the most important surface water resources in the Eastern Anatolian region of Turkey, were investigated. As a result of the examination of the epilithic diatom flora, it was found that the diatom diversity is quite high and the epilithic diatoms are represented by 61 species belonging to 36 genera. Navicula (7 spp.), Epithemia (6 spp.) and Cymbella (3 spp.) were the most abundant genera. In Hazar Lake, centric diatoms were represented by Stephanocyclus meneghinianus and Cyclostephanos dubius. It was determined that a significant proportion of these species were cosmopolitan. It was found that some of the species found in Hazar Lake are ecologically oligotrophic species that prefer alkaline waters.
