DOI: 10.1038/s41598-025-97890-8
Abstract: Korea’s northeastern coastal waters (NECWs) represent the southwestern range of chum salmon (Oncorhynchus keta), spanning temperate and boreal zones. However, understanding their migration to the NECWs in association with environmental changes remains challenging. Using tagging… read more here.

DOI: 10.1111/jfb.14990
Abstract: In chum salmon (Oncorhynchus keta) homed to the Sanriku region, Japan, most of fish is matured in bays and spawn near river mouths in coastal short rivers; therefore, their upriver migration is extremely short, but… read more here.

Congruent population structure across paralogous and nonparalogous loci in Salish Sea chum salmon (Oncorhynchus keta)
Sign Up to like & getrecommendations! Published in 2017 at "Molecular Ecology"
DOI: 10.1111/mec.14163
Abstract: Whole‐genome duplications are major evolutionary events with a lasting impact on genome structure. Duplication events complicate genetic analyses as paralogous sequences are difficult to distinguish; consequently, paralogs are often excluded from studies. The effects of… read more here.
