Microorganisms are instrumental in river ecosystems and participate biogeochemical cycles. It is thought that dynamic hydrological processes rivers influence microbial community assembly, but the seasonal succession assembly of sediments on Loess Plateau remain unclear. This study used high-throughput sequencing technology (16S ITS) neutral model to analyze associated with communities Dali River, a tributary Yellow River Plateau. The results showed sediment bacterial fungal diversity indexes non-flood season were 1.03–3.15 times greater than those flood season. There obvious variations between seasons microorganisms. similarities among all, abundant, rare decreased as geographical distance increased. Proteobacteria (52.5–99.6%) Ascomycota (22.0–34.2%) primary phyla communities. Sediment ammonia nitrogen, water temperature, organic carbon significantly affected (p < 0.05) structure microorganism ecological networks for had complex topological parameters. was driven by deterministic processes, while dominated stochastic processes. These expanded understanding about characteristics provided insights into factors driving networks.

Riparian wetlands can be used as "sentinels" of environmental changes and play pivotal roles in ecological biogeochemical processes. The bacterial community is an essential rapidly responding component riparian areas. However, the co-occurrence patterns phylogenetic group-based processes during wet-dry periods are still open questions. Here, we compared assembly mechanisms soil communities typical across wet dry seasons, which subjected to intensive agricultural activities. results showed that potential functions, composition, network structure, were distinct between seasons. stability complexity season significantly higher than those network. Moreover, null model analysis homogeneous selection (HoS), dispersal limitation (DL), drift (DR) most important for assemblages, with a proportion DL (36.7%) (25.5%) but lower contributions HoS (36.1% versus 41.3%) DR (20.8% 25.4%). dominated by Flavobacteriales, Burkholderiales, Sphingomonadales controlled more limitation, whereas they negatively correlated precipitation, dissolved organic carbon, total carbon season, respectively. These findings expand our understanding vulnerability fragile anthropologically affected wetland ecosystems. IMPORTANCE comprise microbial easily surrounding conditions, especially landscapes wide range ecosystem services. After comparing microbiota, found exhibited stronger limitations season; however, bacteria bacteria. mainly shaped divergence temperature precipitation Revealing variations co-occurrence, seasons critical maintenance diversity regard sceneries.

However, the spatiotemporal variations, assembly processes, co-occurrence patterns, environmental interactions of PA FL bacteria drinking reservoirs remain as yet unexplored. To bridge this gap, we collected samples from 10 sites across four seasons Lake Tianmu, a large reservoir China.

Capacity for nitrogen respiration, fixation, nitrate denitrification was enriched lifestyle, while photosynthesis, methylotrophy, methanol oxidation were lifestyle.
