Diatoms of some saline lakes in the Kiskunság National Park National Park

Kitti Körmendi, Edina Lengyel, Krisztina Buczkó, Csilla Stenger-Kovács

Abstract: Spatial patterns of diatom communities in Hungarian saline lakes are relatively well known, but their changes over time have not been studied yet. The investigation of another large group of silica-scaled algae, the yellow-brown (Chrysophyta) algae and their cysts is far behind the investigation of diatoms. Both of these organisms are excellent indicators of environmental changes, therefore, they are good indicators of processes in water and climate change outside the growing season. Benthic diatoms were collected from mud and aquatic plants of Bába-szék and Bogárzó saline lakes at monthly between May 2013 and May 2014. In the Bába-szék Nitzschia supralitorea, Surirella hoeßeri, Craticula halophila and Halamphora veneta were the most common species, while in Bogárzó Nitzschia palea, H. veneta, N. supralitorea, Navicula wiesneri, Surirella brebissonii and Ctenophora pulchella were dominant, indicating the high trophic state and salinity of these lakes. In the Bába-szék Chrysophyta cysts were present in the end of winter and in the beginning of spring, while in Bogárzó they occurred in summer, autumn and winter. In the investigated lakes both of the algae groups showed strong seasonal pattern.

Keywords: saline lakes, diatoms, Chrysophyceae cysts, Kiskunság National Park, flora.
