Fig. 3

Structural equation model depicting the effects of forest structure (Veg 1, Veg 2), clay content and soil chemical attributes (Soil 2) on decomposition rates (k) and stabilization factor (S) as calculated by the Tea Bag Index. Arrow widths are proportional to the standardized coefficients, which are also indicated next to the line. * P < 0.05, ** P < 0.01, *** P < 0.001. Green arrows indicate positive effects, red arrows negative effects, and grey lines indicate non-significant effects (P > 0.10)
