Extended Data Fig. 6: The path diagrams and path effects of the underlying mechanisms for the relationship between the soil moisture loss (SM loss) and the anomaly of the start of the growing season (SOS) for different arid types.

a-d, The results for arid (a), semi-arid (b), dry sub-humid (c) and humid (d) regions. The numbers represent the mean of standardized path coefficients, with asterisks denote the significance (**P < 0.01; *P < 0.05). The colors and widths of the arrows represent the signs (blue for negative, red for positive) and magnitudes of the path coefficients, respectively. The significance was based on a two-tailed Student’s t-test. En1, En2, Ex1, Ex2, Ex3, Ex32 indicate the effect of six major paths; EnT is the total endogenous effect, and ExT is the total exogenous effect.
