Abstract：Abstract: To investigate and compare the distribution, diversity and dynamics of bacterioplankton communities in Lake Taihu and Lake Yangcheng in Jiangsu Province, China, the bacterial community composition was analyzed from 85 samples using 454-pyrosequencing of 16S rRNA genes. The samples were taken weekly within an intensive time period from June to October 2012. A total of 142 354 clean reads were ge-nerated that were assigned to 4 589 operational taxonomic units (OTUs), with Proteobacteria (mainly γ-Proteobacteria) and Bacteroidetes being the dominant taxa in both lakes. In addition, 19.55% of OTUs, accoun-ting for 95.01% of the total reads, were shared by bacterial communities in the two lakes, which indicated a high degree of overlap between them. The communities in Lake Yangcheng had a higher α-diversity than those in Lake Taihu, which may be mainly attributed to the rare taxa found in both lakes. Interestingly, the results showed that the bacterioplankton composition profile dramatically fluctuated over time. This may be explained by the low capability of the communities to resist external disturbances in extremely shallow lakes. Our study provides information for better understanding of the spatiotemporal dynamics in bacterial communities and differences in their compositions between two related lakes.
