Storage reservoirs are crucial components of long-distance water diversion projects, where may lead to changes in microbial diversity and community structure. Seasonal variations also drive alterations communities. However, the way that microbes assemble under combined effects seasonal storage reservoir has not been extensively studied. Jihongtan Reservoir is terminal Yellow River Qingdao Water Diversion Project (YQWD), which had an average annual period exceeding 290 days recent years. In this study, 16S rDNA amplicon sequencing was used investigate dynamics assembly planktonic bacterial communities during Reservoir. The results indicate bacteria were able maintain stable across all four seasons, while structure underwent significant succession. temperature (WT) found be primary driving environmental factor influencing dynamic Co-occurrence network patterns varied different particularly spring winter. displayed most complexity, showcasing highest connectivity greater stability. contrast, winter simpler, exhibiting lower local but higher global analysis neutral model null revealed relative importance deterministic stochastic processes governing varies seasonally. Stochastic (dispersal limitation) more prominent spring, summer, autumn, (heterogeneous selection) play a role This study essential for gaining comprehensive understanding projects offers valuable references assessment other similar projects.

Seasonal Dynamics of Eukaryotic Microbial Communities in the Water-Receiving Reservoir of the Long-Distance Water Diversion Project, China

Microorganisms, Journal Year: 2024, Volume and Issue: 12(9), P. 1873 - 1873

Published: Sept. 11, 2024

Inter-basin water transfer projects, such as the Yellow River to Qingdao Water Diversion Project (YQWD), are essential for addressing scarcity, but impact local aquatic ecosystems. This study investigates seasonal characteristics of eukaryotic microbial communities in Jihongtan Reservoir, main water-receiving body YQWD, over a one-year period using 18S rDNA amplicon sequencing. The results showed that diversity did not exhibit significant variation (
