Abstract Clarifying the response of soil microbial communities to vegetation restoration is essential comprehend biogeochemical processes and ensure long-term viability forest development. To assess variations in throughout growth Pinus armandii plantations karst region, we utilized “space instead time” approach selected four P. stands with ages ranging from 10 47 years, along a grassland control. The community structure was determined by conducting Illumina sequencing 16 S rRNA gene ITS gene, respectively. results demonstrated that afforestation significantly influenced communities, as indicated notable differences bacterial fungal composition diversity between However, microbe did not display significant variation across stand ages. Moreover, exhibited higher responsiveness age gradients compared community. Soil physicochemical factors play critical role elucidating during processes. TN, AN, TP, AP, SOC, AK, pH were most influencing for community, while TC, pH, TC Our findings indicate substantial changes successive stages Additionally, dominant bacteria fungi characteristics gradient primarily attributed prevailing conditions chemical factors.

Abstract Secondary forest succession after clear‐cutting is one of the foremost ecosystem restoration strategies, while soil microbes play essential roles in processes by modulating nutrient cycling. However, assembly and driving factors microbial communities across secondary remain unclear. Here, we studied examined shifts community‐associated functional dynamics succession. Our results showed that stochastic process was more important shaping bacterial community throughout successional [modified stochasticity ratio (MST) > 50%], fungal initially governed deterministic (MST < 50%), but there a progressive increase selection as proceeded. Soil organic carbon pH were principal for explanation changes structure (total explained 43% change), tree richness productivity 17% change). The relative abundance nitrogen transformation saprotroph groups increased gradually with succession, whereas ectomycorrhizal fungi significantly declined. suggested might accelerate turnover rates. Used together, mechanisms are different highlight those bacteria primarily controlled plant traits properties, respectively. Variations provide new insight into underlying microbe‐driven cycles during
