Absence of population structure of turbot ( Psetta maxima) in the Baltic Sea
Abstract We found low, albeit significant, genetic differentiation among turbot ( Psetta maxima ) in the Baltic Sea but in contrast to earlier findings we found no evidence of isolation by distance. In fact temporal variation among years in one locality exceeded spatial variation among localities. T...
