Figure 3

Structural equation models linking tall tree aboveground biomass (TTB) and tall tree species richness (TTR) with the influences of climate, soil, and stand age factors. Solid lines indicate significant paths (P < 0.05), and dashed lines indicate non-significant paths (P ≥ 0.05). TTB, tall tree biomass; STR, short tree richness; SNR, soil nutrient regime; GDD, growing degree days; CMI, climate moisture index; SA, stand age; SRMR, standardized root mean square residual; GFI, goodness-of-fit index.
