Abstract excerpt

The formation of ecotypes is driven by evolutionary mechanisms that reduce gene flow through complex interactions among ecological, historical and genomic factors. In the European anchovy (Engraulis encrasicolus), marine and coastal ecotypes have been identified in the northeast Atlantic and the Mediterranean Sea, yet the genomic basis of their divergence remains unclear. Here, we present the first genome-scale...
