  1. The models included several predictors (fixed effects illustrated in Fig. 3) and accounted for spatial variations at the hydrographic river basin and site levels (random effects). Marginal R2 accounts for fixed effects and conditional R2 accounts for both fixed and random effects. Mean R2 (95% CI): CI computed using the highest posterior density method.
