Scaled allelic richness _scA_R and scaled expected heterozygosity _scH_exp of sculpin (Cottus spp.; y-axis) and brown trout (Salmo trutta; x-axis) populations. The metric (_scA_R or _scH_exp) is indicated by symbols and colors show populations. The scaling is explained in the main text. The color gradient in the background of the graph and the arrows along the axes visualize possible management priorities from “improve” where genetic diversity is lowest, to “conserve”, where genetic diversity is highest.
