Optimized parameter values, RS (relative support) value as compared to IBD, partial Mantel r and significance of support are shown. Optimized values include equation parameters for x (contrast) and R max (magnitude of the relationship). (A) GD~LV|IBD—partial Mantel test between genetic distance and landscape variable, partialling out the effect of IBD; (B) GD~IBD|LV—partial Mantel test between genetic distance and IBD distance, removing the effect of the landscape variable. The first column of each test indicates the Mantel r‐value and the second column the related p‐value. Supported models are indicated in bold. DEM: digital elevation model; TC: topographical complexity.
