Under the leadership of Prof. Meryem Beklioğlu, Limnology Laboratory explores the ecological structure and functions of lake ecosystems and how they are affected by global changes through international (EU-Framework and Horizon 2020) and national projects. The impact of hydrological changes, global warming and land use are investigated in shallow lakes using experimental and other ecological research approaches. Laboratory and on-site in-situ mesocosm experiments mechanically investigate ecosystem processes (See METU-Mesocosms Sytem). Using the long-term ecological monitoring and paleoecological methods which increase temporal resolution, by combining "space for time" method, which increases spatial resolution. All long-term research data are among the research areas of the Limnology Laboratory in 'process-based modeling'. In all these different research approaches, all trophic groups including microbial loop (bacteria, hetotrophic phylagelate, ciliate), phytoplankton, zooplankton, aquatic plants and fish biomass and diversity (species diversity, character diversity, functional diversity, etc.) in the research scope.
