Contour plot of genetic diversity (π) of Galemys pyrenaicus.Only samples of the same lineage were considered for calculating π at each locality. Colors of the contour plot indicate interpolated genetic diversity. The contour plot is only drawn for the species distribution area. Sample points have been randomly repositioned within a circle of 5 km radius to reveal samples of the same location. A different color is used for each haplotype and therefore a greater variety of colors in an area also indicates higher genetic diversity.
