Geographical distribution of haplotypes (COI)/alleles (ITS1) and haplotype/allele networks for the six widely distributed <i>Nassarius</i> species.

<p>The pie charts on maps indicate the frequency of site-specific and shared halotypes/alleles among sampling sites. For networks, sampled haplotypes/alleles are indicated by circles and missing or unsampled are indicated by dashes. Haplotypes/alleles are color-coded according to sampling locations as shown in maps. Circle size in networks is proportional to the observed haplotype/allele frequency. All maps are made by ArcGIS version 10.0 (ESRI Company, USA).
