Appendix G. Model documentation of carbon sequestration in fine roots including the Danube River water level >10-yearly river water level during the previous growing season (X.HWSGS.1).

Formula: Carbon sequestration in fine roots ~ DIFDIST + DISTUP + X.HWSGS.1 + (1 | Site/Year)

AIC = 712.0; BIC = 727.3; logLik = -350.0; deviance = 700.0; df.resid = 88

Scaled residuals: Min = -1.49882; 1Q = -0.20378; Median = 0.01902; 3Q = 0.12988; Max = 0.42660
