Table 2. Belowground feedbacks affecting Ectomycorrhizal (ECM) colonization drive aboveground feedbacks in total biomass, dependent on the phylogenetic relatedness of conditioned soil. Hedges’ g represents the effect size of differences between the biomass and ECM colonization of plants conditioned by their own soil (conspecific) versus plants conditioned by phylogenetically similar species’ soil (same lineage), or plants conditioned by phylogenetically dissimilar species’ soil (opposite lineage).
