Influence of cryoconcentration on the composition of bacterial communities in semi-enclosed shallow water lakes

Bacteria serve as vital indicators of the lake ecosystem health. Although substantial progress has been made in investigating the structural features of lake bacterial communities, limited attention has been paid to the dynamic assembly processes and driving factors affecting bacterial communities in ice and water environments during the freeze-up period. In this study, we investigated the aggregation and compositional changes in bacterial communities in the internal ice-covered state of Lake Hulun.
