Influence of hydrometeorological factors on the ecological state of the hypersaline lake Saki (Crimea) in 2017–2018

In order to identify the influence of hydrometeorological conditions on the seasonal changes in the ecological state of the salt Lake Saki (Crimea), the dynamics of hydrochemical parameters of wa-ter (salinity, oxygen content, temperature, pH, Eh) and changes in the population of the brine shrimp Ar...
