Fig. 3.

Comparison of putative SNPs significantly associated with each environmental and phenotypic variable. Each row corresponds to a putative SNP that was significantly associated with at least one variable by at least two approaches (Fig. 2). Numbers in brackets under the variable identifiers indicate the total number of SNPs associated to each variable. Color bars indicate the number of approaches supporting each SNP – variable association. AC = antioxidant capacity, TPC = total phenolic content, SWp = surface water pH, SWS = surface water sensitivity to acid rain, MAP = mean annual precipitation, MAR = mean annual runoff, MAT = mean annual temperature, MST = mean summer temperature
