Project Title: TUBITAK- ÇAYDAG- 114Y415 Investigating the response of lake metabolisms and phytoplankton biomass to extreme events through automated high-frequency measurements
Project Information: Freshwater resources are threatened by climate change and human impact. Developed on-site sampling is no longer sufficient for the protection of these resources. By developing high frequency automated systems with technology, collecting data from water sources as often as desired helps us to evaluate the responses of ecosystems to changing environmental conditions, and strengthens future projections. With this project, we aimed to set up a high-frequency automatic monitoring station (HFAMS) in Eymir Lake. For this purpose, the lake ecosystem was closely examined for three years and its interactions with the environment were evaluated. In addition to the scientific part of the project, the citizen science part has been added and the Eymir Lake Ambassadors Training Program (ELATP) has been developed. Scientific information obtained in the project was shared with 5th and 7th grade students and it was aimed to create environmental awareness among students. This project is the expansion of automated monitoring system in Turkey, prominence of scientific thought in terms of education and inoculation of citizens to environmental awareness plays a very important role.

Project Title: TUBITAK 1002: 112Y387 Development of real-time lake monitoring and early warning system prototypes for Eymir Lake
Project Information: In this project, a prototype of a system, which samples and analyzes some physical and chemical variables of water in real-time and which also develops an early warning system for extreme events based on the gathered information, was built. With this prototype continuous water samples will be taken from the lake and measurements of temperature, dissolved oxygen, conductivity, and pH will be held in real-time. Moreover, the results will be transferred to the main web server and stored there. Furthermore, using the functional prototype of this integrated system, real-time data sets will be provided through the web and if needed, former data sets and real-time data will be accessible for further analysis and will be observed graphically on the web page www.eymirlakewatch.com.

Project Title: TUBITAK 109Y181 The Role of Microbial Cycle in Determining the Ecological Structure of Shallow Lakes
Project Information: 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 the Mediterranean climate zone, with 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 the 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 the effect of different zooplankton taxa on the microbial loop community within 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, the effect of water level fluctuations on the microbial loop was determined by the 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. The relationship between a classical food web and the microbial loop was also discussed.

Project Title: TUBITAK – ÇAYDAG- 104Y308. Model and Index Design Predicting Ecosystem Status by Determining the Effects of Salinity and Insecticide Amounts on Daphnia, a Biomarker in Lakes
Project Information: In this study, both how the survival rate and life cycles of Daphnia species change and the key species of freshwater ecosystems, in predator pressure of fish (natural stress factor), increased salinity, and pesticide densities were investigated in-depth laboratory experiments and models. The changes triggered in Daphnia individuals at the molecular level were determined by using FTIR spectroscopy for the first time.

Project Information: The data of twelve lakes in Turkey was investigated to understand the relationship between the hydro-meteorological parameters and release systems (NAO, EAW, M) by using EOF (Empirical Orthogonal Function) and CCA (Canonical Correlation Analysis), and significant results were obtained. The dominant components of the large-scale atmosphere system in the region are identified using EOF analysis. Analyzes were made to understand the climatic effects on the biological structure of Mogan Lake.
