DRI Classical and Molecular Phycological Research Group

Profile of the group: 

The research group is conducting research on planktonic and benthic algae in the Danube River Basin, studying the effects of dynamic water regime, various hydrological events, local and global disturbances, and climate change on the structure and functioning of these communities. Diatoms are one of the most important algae groups of aquatic ecosystems. We study their autecology, morpho- and molecular taxonomy, trait-based and colonization dynamics in running and standing waters (especially the Danube, Fertő, Lake Velencei and Balaton). These results support the applied research as well helping the water and environmental policy-decisions.

The research group focuses on Szigetköz, one of the most important Hungarian branch systems of the Danube, where our group investigates the relationships between functional patterns and environmental variables through the study of functional traits as proxies for adaptation strategies. In order to better understand and interpret current changes, the Group also considers it important to learn about hydrological changes of the past, which can help local changes in the Carpathian Region due to the expected global warming processes in the 21st century. Based on high-resolution diatom studies in the Great Plain, Middle and High Mountain Lakes, we primarily reconstruct water levels, pH and phosphorus content, and intensity of changes on an annual, decade, century, and millennium scale, looking for when rapid transitions occurred.
