Abstract

Water bodies located in the north-east of Yakutia during the period of ice cover were studied. High-throughput sequencing of 16S rRNA gene libraries revealed a high taxonomic diversity of microbial communities in the studied ecotopes. The majority of the under-ice communities was represented by Proteobacteria, Actinobacteriota, Cyanobacteria, Verrucomicrobiota, Bacteroidota, and Planctomycetota. The difference in community diversity between deep-water lakes Labynkyr, Vodorazdelnoye, and Ulu, the source of the Labynkyr River, and shallow-water lakes Myamichi and Mertvoye, the mouth of the Labynkyr River, is shown.
