Summary: | Understanding patterns of dispersal and connectivity among marine populations can directly inform fisheries conservation and management. Advances in high-throughput sequencing offer new opportunities for estimating marine connectivity. We used Restriction-site Associated DNA sequencing to examine dispersal and realized connectivity in the sea scallop Placopecten magellanicus, an economically important marine bivalve. Based on 245 individuals sampled range-wide at 12 locations from Newfoundland to the Mid-Atlantic Bight we identified and genotyped 7163 Single Nucleotide Polymorphisms; 112 (1.6%) were identified as outliers potentially under directional selection. Bayesian clustering revealed a discontinuity between northern and southern samples and latitudinal clines in allele frequencies were observed in 42.9% of the outlier loci and in 24.6% of neutral loci. Dispersal estimates derived using these clines and estimates of linkage disequilibrium imply limited dispersal; 373.1 ± 407.0 km (mean ± SD) for ... : VanWyngaardenM_etal_GeogDistMatrixThis file contains matrices of pairwise geographic distances (km; shortest distance and estimated ocean current-based distance) between 12 populations of the sea scallop, Placopecten magellanicus, used along with 7163 RAD-seq derived SNPs to estimate isolation-by-distance and dispersal distances among populations. Population names and geographic coordinates can be found in Table 1 of the associated publication.VanWyngaardenM_etal_PopStructure_GeogDist.xlsxVanWyngaardenM_etal_RADseq_SNPsThis VCF file contains 7216 RAD-seq derived SNPs detected among 12 Northwest Atlantic Ocean populations of the sea scallop, Placopecten magellanicus. The program stacks v0.9999 was used to call variants; parameters can be found in Table S1 of the associated publication.VanWyngaardenM_etal_PopStructure_SNPMap4b.vcf ... |
