It has long been recognized that pH mediates community structure changes in glacier foreland soils. Here, we showed that pH changes resulted from plant colonization. Plant colonization reduced pH and increased soil organic carbon, which increased bacterial diversity, changed the community structure of both bacteria and fungi, enhanced environmental filtering, and improved microbial network disturbance resistance.
长期以来，人们已经认识到pH值介导了冰川前缘土壤群落结构的变化。在这里，我们表明pH值的变化是由植物定殖引起的。植物定殖降低了pH值并增加了土壤有机碳，这增加了细菌多样性，改变了细菌和真菌的群落结构，增强了环境过滤作用，并提高了微生物网络的抗干扰能力。
