Fig 6. Proportion of hybrids in each species by sampling location.
The proportion of hybrids depending on distance from the coast is measured by the number of sills. (0 = coast; 1 = North Puget Sound; 2 = Central Puget Sound; 3 = Whidbey Basin, Hood Canal and South Puget Sound). Spearman’s rank correlations are provided for each species.
