In my previous work, I focused on investigating effects of harmful cyanobacteria on protozoan grazers, specifically on human pathogenic freshwater free-living amoebae. My current research interests mainly deal with interactive effects of multiple environmental drivers on freshwater food webs in a future climatic scenario –how cyanobacterial populations and their associated toxic production will be affected and what consequences can this have for ecosystem services? To answer these questions, I use mesocosm experiments in combination with routine monitoring and historical data of different lakes. Specifically, I work in a eutrophic lake that is being subjected to biomanipulation attempts aiming at controlling the incidence of toxic cyanobacterial blooms. Finally, I also investigate mechanisms behind alternative stable states in lakes that shift from clear waters, generally dominated by macrophytes, to turbid states caused by massive algal proliferations.
