Continental atlases and co-occurrence patterns of dominant soil archaea with shared habitat preferences in agricultural fields across eastern China. Spearman correlations identified two ecological clusters of dominant taxa with shared habitat preferences, (1) dryland and (2) paddy (a). The above two maps predicted the distributions of dominant archaeal taxa for each identified habitat preference across all sampling fields. Taxonomic compositions at genera level for the two ecological clusters of dominant archaeal taxa were displayed at the left-bottom of each graph. The following four maps show predicted distributions of dominant archaeal taxa for each identified habitat preference in maize and rice fields, respectively. The cross-validation (“CV”) of the maps based on Pearson correlation between the predicted and observed values in each sampling site. Network diagrams with nodes (dominant archaeal taxa) colored by ecological clusters and phylum (b). The size of each node is proportional to the relative abundance of the taxa; the thickness of each connection between two nodes (edge) is proportional to the value of Spearman correlation coefficient
