Chinook salmon collections and migration phenotypes. (a) Map of 12 collection locations corresponding to sites listed in electronic supplementary material, table S1; square = premature adult migration, circle = mature adult migration. (b) Coastal lineage collections—adult fish passage during migration into freshwater; curve colours correspond to collection locations on the map, dashed line = premature, solid line = mature. (c) Interior stream-type lineage collections—adult fish passage during migration into freshwater; curve colours correspond to collection locations on the map, dashed line = premature. (d) Interior ocean-type lineage collections—adult fish passage during migration into freshwater; curve colours correspond to collection locations on the map, dashed line = premature, solid line = mature.
