Gene-environment associations. (a) Spatial visualization of predicted genetic composition by the gradient forest algorithm for all 49 putatively selective loci. The projected rgb colors represent allelic-turnover across the map, including unsampled regions. Sampling locations are indicated with white circles. (b) Cumulative importance of allelic turnover functions of the 49 putatively selective loci with information on the value for each bioclimatic variable value at every sampling location below. Steeper slopes of the response curves indicate a more dramatic change in allelic composition along the bioclimatic gradient.
