Microbial inoculants are constantly introduced into the soil as the deployment of sustainable agricultural practices increases. These introductions might induce soil native communities' dynamics, influencing their assembly process. We followed the impact and successional trajectories of native soil communities of different diversity levels to the invasion by M2E15 (BM) and ECOB02 (BP). Whereas the impact was more substantial when the invader survived (BM), the transient presence of BP also exerted tangible effects on soil bacterial diversity. Community assembly analyses revealed that deterministic processes primarily drove community turnover. This selection acted stronger in highly diverse communities invaded by BM than in those invaded by BP. We showed that resident bacterial communities exhibit patterns of secondary succession following invasions, even if the latter are unsuccessful. Furthermore, the intensification of biotic interactions in more diverse communities might strengthen the deterministic selection upon invasion in communities with higher diversity.
随着可持续农业实践的推广，微生物接种剂不断被引入土壤。这些引入可能会引发土壤原生群落的动态变化，影响其组装过程。我们追踪了不同多样性水平的原生土壤群落对M2E15（BM）和ECOB02（BP）入侵的响应及演替轨迹。当入侵者存活时（BM），影响更为显著，而BP的短暂存在也对土壤细菌多样性产生了切实影响。群落组装分析表明，确定性过程主要驱动群落更替。这种选择在被BM入侵的高度多样化群落中比在被BP入侵的群落中表现得更强。我们表明，即使入侵不成功，常驻细菌群落入侵后也会呈现二次演替模式。此外，在更多样化群落中生物相互作用的强化可能会增强对更高多样性群落入侵时的确定性选择。
