Summary Microbial metacommunities normally comprise generalists and specialists. Uncovering the mechanisms underlying diversity patterns of these two sub‐communities is crucial for aquatic biodiversity maintenance. However, little known about ecological assembly processes co‐occurrence habitat specialists across large spatial scales in plateau lake sediments, particularly regarding their environmental adaptations. Here, we investigated sediment Tibetan lakes role stability metacommunity network. Our results showed that exhibited broader thresholds closer phylogenetic clustering than specialist counterparts. In contrast, stronger signals preferences compared with generalists. Stochastic dominated generalist (63.2%) (81.3%) community assembly. Sediment pH was major factor mediating balance between stochastic deterministic addition, as revealed by network analysis, played a greater maintaining The insights gained from this study can be helpful to understand maintenance microbial lakes.

Lakes are active components of the global carbon cycle and host a range processes that degrade modify dissolved organic matter (DOM). Through degradation DOM molecules synthesis new compounds, microbes in aquatic environments strongly continuously influence chemodiversity, which can feedback to microbial diversity. Developing better understanding biodiversity patterns emerge along spatial environmental gradients is one key objectives community ecology. A changing climate may affect ecological feedback, including those communities. To maintain function lake ecosystem predict cycling environment, it increasingly important understand coupling between unravel biotic abiotic mechanisms control structure communities lakes, we combined high-throughput sequencing ultra-high resolution mass spectrometry together with null modeling approach. The advantage models their ability evaluate relative influences stochastic deterministic assembly both assemblages. present study includes spatiotemporal signatures six temperate lakes contrasting continental Mediterranean climates during productive season. Different conditions nutrient sources characterized studied lakes. Our results have shown high covariance molecular-level diversity individual especially microeukaryotes free-living bacteria indicating dynamic feedback. We found differences climatic regions were mainly reflected at molecular formula-level microeukaryota community. Furthermore, using was governed by variable selection operating consistently within among In contrast, highly across different trophic status regions. Difference governing composition does not indicate weak these components, rather suggests distinct factors be influencing assemblages separately.
