Random forest (RF) analyses identifying the significant (P < 0.05) gene predictors of soil total Hg (a). Panel b includes relationships between total Hg contents and selected functional genes. These functional genes were annotated according to Kyoto Encyclopedia of Genes and Genomes (KEGG) using metagenomic data derived from a subset of our soil samples. Additional information on the KEGG genes is available in Additional file 1: Table S5
