Abstract Multiple evolutionary processes influence genome‐wide allele frequencies and quantifying effects of genetic drift, multiple forms selection remain challenging in natural populations. Here, we investigate variation at major effect loci contrast to patterns neutral drift across a wide collection steelhead ( Oncorhynchus mykiss ) populations that have declined abundance due anthropogenic impacts. Whole‐genome resequencing 74 revealed (~8 million SNPs) consistent with expected population structure. However, allelic associated adult migration timing (chromosome 28: GREB1L / ROCK1 age maturity 25: SIX6 reflected how has acted on phenotypic Variation was influenced by differing signals between the strongly divergent Coastal Inland lineages, while within among lineage been driven local as well recent influences. Recent appeared frequency alleles including artificial for specific traits hatchery stocks subsequent gene flow into Selection from environmental factors various scales also likely alleles. These results reveal mechanisms are critical conservation life history this protected species.

ABSTRACT Migration is an important component of the life cycles many organisms and differences in migration timing can greatly influence fitness. Variation (hereafter referred to as run timing) found salmon species contributes portfolio history diversity that vital for maintaining healthy populations. Pink ( Oncorhynchus gorbuscha ) are composed temporally isolated lineages spawn even odd years. Here, we focus on early late runs pink Auke Creek, Alaska, which a few weeks apart same ≈50m stretch stream. We conducted low coverage, whole genome sequencing from both investigate genetic basis this system. Within lineage detected major effect locus displaying high divergence between individuals chromosome 10 genome. This showed lower - but still elevated amount lineage.
