Biogenic Migration of Nitrogen and Phosphorus in Crimean Hypersaline Lakes: A Seasonal Aspect

— The paper presents data on seasonal fluctuations in hydrochemical characteristics and the supply dynamics of biogenic elements in four hypersaline lakes in Crimea: Sasyk-Sivash, Oiburg, Konrad, and Sakskoe (eastern basin) in 2017. The migration pathways of biogenic elements in the hypersaline lakes are determined depending of natural and anthropogenic factors. The role of the elements in ecosystem processes, the formation of peloids, and the functioning of communities of organisms are discussed. Probable transformation scenarios of the ecosystems of saline lakes are considered as a function of climatic changes, increasing anthropogenic load, and related increase in the inflow of biogenic elements.
