Correlation between the soil core ecological clusters and soil ecosystem multifunctionality. (A) Co-occurrence networks based on the Weighted Gene Co-Expression Network Analysis (WGCNA). The colors of the nodes represent different ecological clusters. (B) The regression relationships between soil ecological multifunctionality index and the relative abundance of core taxa within the main ecological clusters. Statistical analysis was performed using ordinary least squares linear regressions; p values were indicated by asterisks (**p < 0.01; ***p < 0.001)
