Assessing Climate and Human Activity Effects on Hypersaline Lake Ecosystem: Case Study of Saki Lake, Crimea

In the Crimean Peninsula, there are several hypersaline lakes that have hydromineral and biological resources. However, they under a significant anthropogenic load, which together with climate change leads to negative consequences for ecosystems. The aim of work was study seasonal changes physicochemical parameters water (temperature, pH, oxygen content, salinity, redox potential Eh, optical density transparency) Artemia population in Saki Lake 2022. For daily fluctuations temperature, O2, CH4 CO2, vertical temperature profile measuring system installed at boundaries air, bottom depth 4 m spatial discreteness 0.2 m. drive sensors content gases assay air were installed. increase salinity Eh summer accompanied by an temperature. Simultaneously, decreases pH brine been observed. cysts found throughout year, nauplii mostly available during spring autumn, adults shown summer. obtained results demonstrated ecosystem within ongoing change, can be used development optimal management mineral resources such bodies.
