Abstract

Alakol Lake is a unique protected natural water body with a gradient of salinity in which algal diversity has never been studied before our research. We revealed 208 algal species from five taxonomic Divisions during 2016-2017 studies. Diatom species were strongly prevailing in the 29 studied communities of the lake. Statistical methods revealed a high correlation between the intensity of algae development and the number of species in the community, as well as the high individuality of the algae communities at the three studied sites on the CCA. The applied analysis of the distribution of taxonomic divisions and indicator categories using statistical maps showed that euglenoid species, which mostly correlated with organic matter input, are distributed in the lake from the Rybachje settlement. A mapping of bioindication groups revealed an influence of hidden and inflowing rivers Urzhar and Zhamanty as sources of organic pollution. This conclusion can be made on statistical mapping only in addition to bioindication results because environment variables usually are limited. This assessment of protected lake can serve as a reference for future investigation of the Alakol Lake as well as can help to plan a set of stations for monitoring.
