Fig. 9: Quantification of the effects of soil temperature and moisture on heterotrophic respiration.

From: Various responses of global heterotrophic respiration to variations in soil moisture and temperature enhance the positive feedback on atmospheric warming

Fig. 9

a Structural equation modeling evaluates the relationship between atmospheric CO2, ST, SM, and Rh, Chisq/df=0.433; CFI = 0.993; RMSEA = 0.006; SRMR = 0.015; *: p < 0.05; b Variance decomposition quantifies the contributions of ST, SM, and other factors to Rh variation.
