Genomic differentiation in Pacific cod using Pool-Seq.

ABSTRACT: Patterns of genetic differentiation across the genome can provide insight into selective forces driving adaptation. We used pooled whole genome sequencing, gene annotation, and environmental covariates to evaluate patterns of genomic differentiation and to investigate mechanisms responsible for divergence among proximate Pacific cod (Gadus macrocephalus) populations from the Bering Sea and Aleutian Islands and more distant Washington Coast cod. Samples were taken from eight spawning locations, three of which were replicated to estimate consistency in allele frequency estimation. A kernel smoothing moving weighted average of relative divergence (F _ST) identified 11 genomic islands of differentiation between the Aleutian Islands and Bering Sea samples. In some island
