A fundamental goal of reservoir ecosystem management is to understand bacterial biogeographic patterns and the mechanisms shaping them at a regional scale. However, little known about how eutrophication, major water quality challenge in reservoirs, influences sediment subtropical regions. In this study, communities were sampled from 21 reservoirs Hanjiang river basin, southern China, spanning trophic states oligotrophic eutrophic. Our findings demonstrated that eutrophication-driven changes total carbon (TC) significantly shaped communities, weakening "distance-decay" relationships typically link community similarity geographical distance. TC content exceeding threshold 13.2 g·kg-1 resulted substantial shifts structure. Specifically, high levels promoted dominance copiotrophic bacteria such as Syntrophales (Deltaproteobacteria), Clostridiaceae (Firmicutes), VadinHA17 (Bacteroidetes), while taxa like Anaerolineaceae (Chloroflexi) Nitrospirota prevalent low sediments. Additionally, higher was associated with increased heterogeneity composition. Reservoirs elevated exhibited more complex interaction networks, characterized by stronger niche segregation competition compared networks. Overall, these underscore pivotal role biogeography They provide valuable insights for predicting responses eutrophication offer guidance mitigating impacts anthropogenic activities on freshwater ecosystems.

This study systematically investigated the effects of temperature changes on degradation antibiotics in soil, as well alterations microbial community structure and aggregation, through a field warming experiment greenhouse. Compared to non-warming treatment significantly accelerated rate tetracyclines during soil freezing mitigated impact environmental fluctuations communities. The greenhouse environment promoted growth reproduction wide range taxa, but abundance Myxococcota was positively correlated with antibiotic concentrations both treatments, suggesting potential specific association processes. Long-term led shift assembly process communities, decrease dispersal limitation an increase drift process. Furthermore, co-occurrence network analysis revealed more loosely structured along emergence new characteristic taxa. Notably, than 60% key taxa that connected networks groups belonged rare indicating play crucial role maintaining function.
