揭示微生物群落的结构机制是微生物生态学的核心目标，但对群落组装过程与生活栖息地的关系仍缺乏详细的了解。本文通过16S rRNA基因扩增测序，研究了渤海不同生境（水体与沉积物、自由生活（FL）与颗粒相关（PA））中微生物群落的组装过程及其对类群间关联模式的影响。结果表明，不同生境的微生物群落组成和多样性存在明显差异，其中水体和沉积物的差异性大于FL和PA群落的差异性。微生物群落的聚集主要受扩散限制、生态漂移和同质选择的影响，但不同生境微生物群落聚集的相对重要性不同。扩散限制和生态漂变是影响底栖动物群落结构的主要因素，而同质选择对底栖动物群落结构的形成起着更重要的作用。此外，组装机制之间的FL和PA社区，特别是在底层水的FL和PA组分的生态漂移和扩散限制的影响更大，分别。将组合过程与同现模式联系起来表明，在更紧密的同现关系下，确定性过程（主要是同质选择）的相对贡献增加。相比之下，随机过程产生了较高的效果时，有较少的类群间的连接。总的来说，我们的研究结果表明，对比的生态过程支持微生物群落分布在不同的栖息地，包括不同的生活方式，这表明复杂的微生物动力学模式在沿海系统与高人为扰动。
Unraveling the mechanisms structuring microbial community is a central goal in microbial ecology, but a detailed understanding of how community assembly processes relate to living habitats is still lacking. Here, via 16S rRNA gene amplicon sequencing, we investigated the assembly process of microbial communities in different habitats [water verse sediment, free-living (FL) verse particle-associated (PA)] and their impacts on the inter-taxa association patterns in the coastal Bohai Sea, China. The results showed clear differences in the composition and diversity of microbial communities among habitats, with greater dissimilarities between water column and sediment than between FL and PA communities. The microbial community assembly was dominated by dispersal limitation, ecological drift, and homogeneous selection, but their relative importance varied in different habitats. The planktonic communities were mainly shaped by dispersal limitation and ecological drift, whereas homogeneous selection played a more important role in structuring the benthic communities. Furthermore, the assembly mechanisms differed between FL and PA communities, especially in the bottom water with a greater effect of ecological drift and dispersal limitation on the FL and PA fractions, respectively. Linking assembly process to co-occurrence pattern showed that the relative contribution of deterministic processes (mainly homogeneous selection) increased under closer co-occurrence relationships. By contrast, stochastic processes exerted a higher effect when there were less inter-taxa connections. Overall, our findings demonstrate contrasting ecological processes underpinning microbial community distribution in different habitats including different lifestyles, which indicate complex microbial dynamic patterns in coastal systems with high anthropogenic perturbations.
