5. Biplots showing results of RDA analyses on the best model for
neutral (left, N= 3,820) and outlier (right, N= 24) SNP datasets of the
intertidal marine gastropod Nucella lapillus . Coloured points on
the biplots correspond to sampling sites indicated on the inset map.
Arrows represent predictor variables that significantly explain
population genetic structure for each dataset. Online version in colour.
