Soil microbial communities and processes have repeatedly been shown to impact plant community assembly and population growth. Soil-driven effects may be particularly pronounced with the introduction of plants to non-native ranges, as introduced plants are not typically accompanied by transference of local soil communities. Here we describe how the mechanisms by which soil community processes influence plant growth overlap with several known and well-described mechanisms of plant invasion. Critically, a given soil community process may either facilitate or limit invasion, depending upon local conditions and the specific mechanisms of soil processes involved. Additionally, as soil communities typically consist of species with short generation times, the net consequences of plant-soil feedbacks for invasion trajectories are likely to change over time, as ecological and evolutionary adjustments occur. Here we provide an overview of the ecological linkages of plant-soil feedbacks and underlying mechanisms of invasion.
土壤微生物群落和过程反复被证明会影响植物群落组装和种群增长。随着植物被引入非原生范围，土壤驱动的影响可能尤为明显，因为引入的植物通常不会伴随着当地土壤群落的转移。在这里，我们描述了土壤群落过程影响植物生长的机制如何与几种已知的和描述良好的植物入侵机制重叠。关键是，给定的土壤群落过程可能促进或限制入侵，这取决于当地条件和涉及的土壤过程的具体机制。此外，由于土壤群落通常由具有短世代时间的物种组成，因此植物-土壤反馈对入侵轨迹的净后果可能随着时间的推移而发生变化，因为会发生生态和进化调整。在这里，我们提供了植物-土壤反馈的生态联系和入侵的潜在机制的概述。
