Bacteria, nanoflagellates and ciliates constitute the microbial loop and it is a model of the pathways of carbon and nutrient cycling through microbial components of pelagic aquatic communities. Relations between bacteria and bacterivores are not fully understood, especially lakes in Mediterranean climate zone, in respect to their changes with the eutrophication and hydrological changes. Despite their abundance and likely importance in shallow lake ecosystems, little is known about the microbial communities, their interactions and their response to environmental changes. Most of studies were done in temperate and tropical climatic zones. We comprised a comparative study of the microbial food web community along north to south latitudinal gradient with contrasting nutrient and predation states. Little is known about the impact of trophic cascade on microbial loop and often the results are contradictory. We investigated effect of different zooplankton taxa on microbial loop community with in situ food web experiments in 14 lakes along north to south latitudinal gradient. The effect of seasonality was determined by monitoring in Lakes Eymir and Mogan. However, effect of water level fluctuations on microbial loop was determined by mesocosm experiment in Lake Eymir. We focused on explaining how the microbial loop changes with respect to trophic level of lakes, seasonality, hydrology and grazing effect of zooplankton. Relationship between classical food web and microbial loop was also discussed.
