Phylogenetically diverse introgression drives subtle population structure in Pacific rockfishes.

ABSTRACT: Genomic methods have shown that admixture and introgression is common across animal taxa. Pacific rockfishes, genus Sebastes, are group of commercially important species that primarily inhabit inshore, shelf, and slope habitats along the North American west coast. Among these, Copper and Quillback Rockfishes (abbreviated to Copper and Quillback) are closely related species known to hybridize, particularly within the Salish Sea in North America's Pacific Northwest. Here, we investigate genetic population structure and introgression patterns in Copper and Quillback from Alaska to California. Using whole-genome resequencing (WGS) across a broad geographic range, we seek to (1) compare population structure between these species, and (2) assess how introgression affects population struct
