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.
