生物多样性的日益丧失深刻地影响着群落结构和生态系统的功能。然而，在社区组装和潜在的驱动程序的共生网络结构的土壤真菌和细菌与树种丰富度梯度的差异记录甚少。在这里，我们研究了土壤真菌和细菌群落在中国亚热带树木物种丰富度实验（从1到16种）使用扩增子测序靶向rRNA基因的内转录间隔区2和V4高变区，分别。树种丰富度对真菌和细菌的多样性没有显著影响。除土壤和空间距离外，树种丰富度和组成对真菌群落组成有显著影响，但对细菌群落组成无显著影响。在真菌而不是细菌共生网络中，平均度，度集中度和聚类系数显着降低，但模块性显着增加树种丰富度。真菌共生网络结构受树种丰富度、群落组成和土壤碳氮比的影响，而细菌共生网络结构受土壤pH和空间距离的影响。本研究表明，亚热带森林土壤真菌和细菌的群落聚集和共生网络结构的潜在驱动力不同。生物多样性的日益丧失深刻地影响着群落结构和生态系统功能。因此，揭示微生物群落沿着植物物种多样性梯度的聚集和共生网络结构的相关机制，对于理解植物多样性丧失后的生物多样性维持和群落稳定性具有重要意义。在这里，我们比较了亚热带树木多样性实验中土壤真菌和细菌的共生网络结构的群落组装和潜在驱动因素的差异。除了土壤和空间距离外，植物对真菌的群落和共生网络结构的预测性比细菌更强。该研究强调，在亚热带树木多样性实验中，植物在塑造群落组装和真菌的相互作用方面发挥着比细菌更重要的作用。
Increasing biodiversity loss profoundly affects community structure and ecosystem functioning. However, the differences in community assembly and potential drivers of the co-occurrence network structure of soil fungi and bacteria in association with tree species richness gradients are poorly documented. Here, we examined soil fungal and bacterial communities in a Chinese subtropical tree species richness experiment (from 1 to 16 species) using amplicon sequencing targeting the internal transcribed spacer 2 and V4 hypervariable region of the rRNA genes, respectively. Tree species richness had no significant effect on the diversity of either fungi or bacteria. In addition to soil and spatial distance, tree species richness and composition had a significant effect on fungal community composition but not on bacterial community composition. In fungal rather than bacterial co-occurrence networks, the average degree, degree centralization, and clustering coefficient significantly decreased, but the modularity significantly increased with increasing tree species richness. Fungal co-occurrence network structure was influenced by tree species richness and community composition as well as the soil carbon: nitrogen ratio, but the bacterial co-occurrence network structure was affected by soil pH and spatial distance. This study demonstrates that the community assembly and potential drivers of the co-occurrence network structure of soil fungi and bacteria differ in the subtropical forest. IMPORTANCE Increasing biodiversity loss profoundly affects community structure and ecosystem functioning. Therefore, revealing the mechanisms associated with community assembly and co-occurrence network structure of microbes along plant species diversity gradients is very important for understanding biodiversity maintenance and community stability in response to plant diversity loss. Here, we compared the differences in community assembly and potential drivers of the co-occurrence network structure of soil fungi and bacteria in a subtropical tree diversity experiment. In addition to soil and spatial distance, plants are more strongly predictive of the community and co-occurrence network structure of fungi than those of bacteria. The study highlighted that plants play more important roles in shaping community assembly and interactions of fungi than of bacteria in the subtropical tree diversity experiment.
