Appendix C. Model documentation of carbon sequestration in fine roots without climate and flooding parameters.
Formula: Carbon sequestration in fine roots ~ Magnitude of fluctuation in the groundwater table (DIFDIST) + Distance to upstream boundary of the study area (DISTUP) + (1 | Site/Year)
AIC = 735.1; BIC = 747.8; logLik = -362.5; deviance = 725.1; df.resid = 89
Scaled residuals: Min = -1.19551; 1Q = -0.26042; Median = -0.01012; 3Q = 0.13792; Max = 0.27327
