Parallel adaptive evolution of geographically distant herring populations on both sides of the North Atlantic Ocean
Identification of genetic changes that allow a species to adapt to different environmental conditions is an important topic in evolutionary biology. In this study we analyzed whole-genome resequencing data of Atlantic herring populations from both sides of the Atlantic Ocean and identified a number...

Summary: | Identification of genetic changes that allow a species to adapt to different environmental conditions is an important topic in evolutionary biology. In this study we analyzed whole-genome resequencing data of Atlantic herring populations from both sides of the Atlantic Ocean and identified a number of loci that show consistent associations with spawning time (spring or autumn). Several of these loci, such as thyroid-stimulating hormone receptor (TSHR), have a well-established role in reproductive biology, whereas others have never been implicated in controlling reproduction. Genetic variants associated with adaptation to spring or autumn spawning are shared to a large extent among populations across the Atlantic Ocean and the Baltic Sea, providing evidence for parallel adaptive evolution. |
