ESMTable 3 Results of Canonical Correspondence Analysis (CCA) of diatom-environment relationships for the Ebro Delta samples. a) Marginal effects indicate the variance explained by each variable considered alone. b) Unique effects indicate percentage of variance explained by each environmental variable, with the remaining variables treated as covariables. λ1: eigenvalue of the constrained axis 1; λ1/λ2 : ratio of the constrained axis 1 to the unconstrained axis 1. In bold are those variables initially selected by the CCAs. In bold and highlighted in gray colour are the final variables selected by the partial CCAs. T: temperature (ºC); pH; DO: dissolved oxygen saturation (%);Sand = sand proportion; OM = organic matter content; PO43–-P: orthophosphate-phosphorus (µg/L); NH4+-N: ammonium-nitrogen (µg/L); NO2–-N: nitrite-nitrogen (µg/L); NO3–-N: nitrate-nitrogen (µg/L); SiO44–-Si: orthosilicate-silicon (µg/L); Chl-a: seston chlorophylla (µg/L); Pheo-a: pheophytina (µg/L)

ESM Table 4Model performances for the diatom-based conductivity transfer functions (WA-INV, WA-CLA, WATOL-INV, WATOL-CLA). All models were cross-validated using the leave-one-out method (LOO, also called jack-knifing) and leave-one-site-out (LOSO), and were built on square root transformed species data and log10 transformed conductivity. Abbreviations: WA = Weighted-Averaging; INV = Inverse deshrinking; CLA = Classical deshrinking; WATOL = Weighted-Averaging with tolerance downweighted. The model preferred is highlighted in bold and gray colour
