Scatterplots of genetic (FST) vs. geographic distances between sockeye salmon populations from Iliamna Lake. Scatterplots used (a) 38 SNPs ('No Outliers'), (b) 39 SNPs including One_MHC2-190 ('Outlier 1'), or (c) 39 SNPs including One_MHC2-251 ('Outlier 2'). Legend for population comparisons--tributary-tributary: yellow squares; tributary-island beach: purple circles; tributary-mainland beach: red circles. Regression lines and coefficients of determination (R2) were only reported for tributary-island beach (purple) and tributary-tributary comparisons (black) as no significant isolation-by-distance patterns were found for tributary-mainland beach comparisons.
