Abstract

EXECUTIVE SUMMARY
 Population structuring of whelk populations investigated by mitochondrial DNA sequencing.
 Significant genetic differentiation among sites supports population structuring on small geographical scales.
 Genetic patterns also implicate environmental heterogeneity as a driver of reported phenotypic variation.
 Genetic variation among Welsh whelk seems to be considerably lower than other regions which may be attributed to small population sizes and/or overharvesting.
 Genetic stock structure must be included in management plans aimed at sustainable harvesting.
 Such plans must also endeavour to prevent further loss of genetic variation as this represents the ‘raw material’ for populations to respond to future climate change.
