Soil Biogeochemical Cycle Couplings Inferred from a Function-Taxon Network
Carbon biogeochemical cycle genes in forest soils. (a) Carbon biogeochemical cycle; arrow thickness indicates proportion of biomarker gene contigs for corresponding pathways. (b) Linear relationships between contigs and latitude. Asterisks indicate significant correlation with latitude (,). (c) Proportion of contigs assigned to known taxa. (d) Distribution of known taxa.
