The large-scale population genetic structure of northern shrimp, Pandalus borealis, was investigated over the species’ range in the North Atlantic, identifying multiple genetically distinct groups. Genetic divergence among sample localities varied among 10 microsatellite loci (range: FST = −0.0002 to 0.0475) with a highly significant average (FST = 0.0149; P < 0.0001). In contrast, little or no genetic differences were observed among temporal replicates from the same localities (FST = 0.0004; P = 0.33). Spatial genetic patterns were compared to geographic distances, patterns of larval drift obtained through oceanographic modelling, and temperature differences, within a multiple linear regression framework. The best-fit model included all three factors and explained approximately 29% of all spatial genetic divergence. However, geographic distance and larval drift alone had only minor effects (2.5–4.7%) on large-scale genetic differentiation patterns, whereas bottom temperature differences explained most ... : Pandalus borealis microsatellite dataMicrosatellite data (10 loci) for northern shrimp, Pandalus borealis: 2053 individuals, representing 21 samples and 16 geographic localities throughout the species' range in the North Atlantic.popborealis.zip ...
