Abstract

The relationship between epipelic diatom communities and 16 environmental variables from two gypsum karstic lakes in central Anatolia was explored using canonical corresondence analysis. Temperature, ammonium (NH4+), sulphate (SO42-) and calcium (Ca2+) concentrations were the most important variables related to species distribution. The genera Mastogloia, Gomphonema, Navicula, Cymbella, and Nitzschia were the richest in taxa. Diatom species associated with temperature, NH4+, SO42- and Ca2+ gradients were Mastogloia braunii, Mastogloia smithii var, lacustris, Campylodiscus clypeus, Navicula salinarum and Amphora coffeaeformis.
