Deciphering Planktonic Bacterial Community Assembly in the Storage Reservoir of the Long-Distance Water Diversion Project

Microorganisms, Год журнала: 2025, Номер 13(2), С. 465 - 465

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.

This study presented a comprehensive analysis of the microbial ecology in water diversion rivers (WDRs) source area East Route South-to-North Water Diversion Project (ER-SNWDP) China across various periods. Proteobacteria, Chloroflexi, Acidobacteriota, and Bacteroidota were identified as dominant phyla river sediment. During wet period, communities exhibited highest richness, biodiversity, most intense antagonistic relationships compared to those dry normal Generally, network predominantly existed symbiotic models characterized by mutual benefit symbiosis throughout all co-occurrence was found be complex, with OTUs showing closest interconnections. The mechanisms governing community diversity, succession, biogeography spatial turnover species stochastic processes. A more pronounced impact processes on assemblages observed during or periods than period. Functional prediction metabolic pathways indicated that main ecological functions encompassed carbohydrate metabolism, amino acid energy etc. could provide essential scientific data for regulation, protection, resources management WDRs.

Geographical and Environmental Factors Differentially Shape Planktonic Microbial Community Assembly and Resistomes Composition in Urban Rivers

Global Change Biology, Год журнала: 2025, Номер 31(4)

Опубликована: Апрель 1, 2025

ABSTRACT Global urbanization accelerates pollution challenges in urban rivers, including increased transmission of bacterial antibiotic resistance genes (ARGs), severely threatening the health aquatic ecosystems and human health. Yet, systematic knowledge differences distribution community assembly patterns across rivers at a continental scale is still insufficient. In this study, we conducted extensive sampling nine representative China. We used amplicon shotgun metagenomic sequencing, state‐of‐the‐art bioinformatics, multivariate statistics to investigate mechanisms planktonic microbiomes (i.e., bacterioplankton microeukaryotes), their resistomes, i.e., ARGs metal (MRGs). Geographical environmental factors played pivotal role shaping vs. resistomes studied rivers. Phylogenetic‐bin‐based null model analysis (iCAMP) indicated that microbiomes, dominated by dispersal limitation drift, tend toward spatial heterogeneity. contrast, driven deterministic processes, display more similar patterns. Cross‐validated Mantel tests revealed geographical geographic distance) were primary regulators microbial assembly, while temperature) control processes resistomes. Our findings provide crucial insights into driving biogeographical entities scale, offering valuable implications for mitigating managing spread from environment humans.
