Temporal stability and assignment power of adaptively divergent genomic regions between herring ( Clupea harengus) seasonal spawning aggregations
Abstract Atlantic herring ( Clupea harengus ), a vital ecosystem component and target of the largest Northwest Atlantic pelagic fishery, undergo seasonal spawning migrations that result in elusive sympatric population structure. Herring spawn mostly in fall or spring, and genomic differentiation was...
