From: Tree species diversity predicts aboveground carbon storage through functional diversity and functional dominance in the dry evergreen Afromontane forest of Hararghe highland, Southeast Ethiopia

Fig. 3

The best-fit structural equation models (SEMs) for linking species richness, functional diversity, functional dominance, and AGC storage. a Full mediation, b partial mediation. The figures on the lines are the standardized path coefficients. The figures in the box represent the coefficient of determination (R2). Red arrows denote negative effect paths. Black arrows denote positive effect paths. Double-pointed lines represent the residual correlations. We present the significance of each path and model fit statistics in Table 1. AGC, aboveground biomass carbon; FRic, functional richness; FEve, functional evenness; FDis, functional dispersion; FDiv, functional divergence; CWM, community weight mean; WD, wood density; SLA, specific leaf area; PHm, maximum plant height
