Caption

Geographic distribution of population samples included in the genetic study. Green dots mark samples of autumn-spawning herring while all remaining colours represent different clusters of spring-spawning herring. The size of dots reflects the sample size as indicated. STH36A, KAL05 and KAL06 are three outlier populations that genetically cluster with the Southern populations despite their geographic location.
