Fig. 3: Relationships between ectomycorrhizal (EcM) tree dominance and carbon stocks with climate (CL), different successional stages (SUS), or different species richness (SR) were examined.

From: Forest carbon stocks increase with higher dominance of ectomycorrhizal trees in high latitude forests

Fig. 3

Panels (a), (d), and (g) illustrate tree, soil and forest carbon stocks with changes in climate; panels (b), (e), and (h) depict tree, soil and forest carbon stocks with changes in successions; while panels (c), (f), and (i) show tree, soil and forest carbon stocks with changes in tree species richness. To meet the normality assumption, all carbon stock components are ln-transformed. Each dot on the plots represents a single plot. Mixed-effects models were fitted to test whether relationships between EcM tree dominance and different carbon storage components changed along the species-richness gradient, across successional stages, or with climate changes (see Supplementary Table S1 for statistical results). EcM × SR, EcM × SUS, and EcM × CL represent the interactions.
