| 英文摘要 | While growing attention has been focused on the microbial responses to precipitation changes from the perspectives of prokaryotic and fungal groups, most studies have ignored higher trophic level microorganisms despite their importance in ecosystem functions. In this study, field manipulation experiments, including 40 %- 60 % increases in precipitation (IP) and 40 %-60 % decreases in precipitation (DP), were performed in a coastal wetland for three years to investigate the responses of soil bacteria, fungi, and protists (cercozoa) as well as crosstrophic co-occurrence patterns. Bacterial and protistan community structures were significantly changed in the IP regime and marginally changed in the DP regime, while the fungal community structure was only reshaped by the IP regime. Microbial communities were mostly reshaped by salinity, temperature, and TN. In the DP regime, protistan-bacterial and protistan-fungal co-occurrence became more clustered and involved fewer species, with the majority of node loss occurring among bacterial species, suggesting increased potential predation efficiency. In IP regime, cross-trophic networks expanded in size and became less clustered, suggesting more species involved in potential predation with lower efficiency. Temperature and salinity were the most important environmental factors affecting both microbial community structure and cross-trophic co-occurrence patterns. Structural equation models (SEM) revealed that shifts in protistan-bacterial co-occurrence patterns enhanced soil respiration (SR) in the DP regime but reduced it in the IP regime. Besides, the contribution of cross-trophic interactions to SR exceeded microbial diversity. These findings provided mechanistic understandings of the responses of multi-trophic interactions to precipitation changes and indicated their contribution to soil respiration is critical. |
