Fig. 7: Isolation by distance and genetic structure in M. guttatus across spatial scales.

(a) Isolation by distance plot showing the association between geographic distance and genetic distance across the Sierra Nevada, (b) Isolation by distance plot for range-wide populations, (c) Semivariogram showing genetic divergence as a function of distance for Sierra Nevada populations, with symbols showing semivariance for a given lag-distance and the line the best fitting model, (d) Semivariogram of genetic divergence relative to distance for range-wide populations.
