Dr. Beata Messyasz has been an associate professor in the Department of Hydrobiology, Faculty of Biology, Adam Mickiewicz University, in Poznań since 2016, where she obtained her doctorate with a dissertation entitled "Dependencies between phytoplankton and physical and chemical elements in six lakes of Struga Gołaniecka". Her scientific interests focus on the functioning of phytoplankton, phytobenthos and periphyton communities in extremely trophically different lakes, the ecology of algae in lakes and rivers in a vertical and spatial profile, the eutrophication of lakes and the mass appearances of algae. This scope has been extended and deepened to include research on freshwater macroscopic algae from the group of green algae in terms of taxonomic, habitat and thalli chemistry.
