Figure 6
Structural equation models (SEM) depicting the control of cattle (A) vs. sheep grazing (B) on litter decomposition by affecting soil properties (n = 8) and litter quality (n = 6). The numbers on the arrows are standardized path coefficients, continuous and dashed arrows indicate positive and negative effects, respectively. The path widths are scaled proportionally to the path coefficient. The R2 value represents the proportion of total variance explained for the dependent variable of interest. Overall, goodness of-fit tests are shown in the bottom of the figure. *P < 0.05, **P < 0.01 and ***P < 0.001.
