Hierarchical genetic structure in a direct-developing whelk ( Buccinum undatum ) throughout the western North Atlantic
Direct-developing marine species lack a pelagic larval phase and are therefore predicted to have limited dispersal capacity and exhibit strong genetic structure over small spatial scales. Nevertheless, empirical work suggests that developmental mode, alone, cannot always explain realized connectivit...

Direct-developing marine species lack a pelagic larval phase and are therefore predicted to have limited dispersal capacity and exhibit strong genetic structure over small spatial scales. Nevertheless, empirical work suggests that developmental mode, alone, cannot always explain realized connectivity patterns. We characterized spatial genetic structure within the western North Atlantic lineage of the waved whelk ( Buccinum undatum) , a direct-developing gastropod that is the target of an emerging fishery. We genotyped individuals throughout Atlantic Canada using 1052 single nucleotide polymorphisms, documenting strong hierarchical genetic structuring throughout this region.
