Conclusion
In this study, we selected 5 typical ecosystems in a successional gradient and conducted a short-term climatic stress simulation experiment to determine the role interactions play in governing the RSRs of microbial community stability. The results indicated that the microbial community showed a rough trend of decreasing resistance and increasing resilience through the successional stages, and highlighting the importance of the role of positive and negative interaction balance in governing the microbial community, which could offer valuable and meaningful guidance for artificial community composition, ecosystem stability assessment, and biological conservation formulation.
Data availability: The original sequences were up loaded to NCBI (SRA). The bacterial community sequences about O, T1, U1, T2 and U2 were in BioProjects PRJNA721797, PRJNA721832, PRJNA721803, PRJNA721850 and PRJNA721838, respectively. And the fungal community were in BioProjects PRJNA721852, PRJNA721860, PRJNA721854, PRJNA721886 and PRJNA721876, respectively.
