The importance (i.e., percentage increase of mean squared error - %IncMSE) of different factors on the ARG composition (A) and richness (B), analyzed by random forest modelling. Asterisks indicate the significant importance of factors: *p < 0.05; **p < 0.01. C Co-occurrence network showing the association of affected ARGs with bacterial and protist genera. Each node represents a taxon at the genus level. The node of protists is displayed at the order level. Size of node is proportional to the number of connections. Thickness of edges is proportional to Spearman correlation coefficients, divided into positive (ρ ≥ 0.3, p < 0.001; grey) or negative (ρ ≤ −0.3, p < 0.001; red) edges. A summary of node–edge statistics is provided at the bottom left of the network. Colored numbers represent the number of nodes belonging to the corresponding category. Numbers in backets denote the number of inner connections. The grey and red numbers adjacent to edge connections represent positive and negative cross-group interaction.
