In the North Atlantic and the Arctic Ocean, four species of the copepod genus Calanus dominate the zooplankton biomass. Because of their morphological resemblance, knowledge of their respective distribution range has long been biased by misidentification, until the recent use of molecular tools uncovered numerous areas of sympatry. As hybridization between Calanus finmarchicus and C. glacialis has been claimed in the East-Canadian Arctic based on microsatellites, we investigated further the potential for interbreeding in newly uncovered areas of sympatry. Calanusspecies and stage composition were analyzed during winter in two Norwegian subarctic fjords, using molecular markers developed specifically for species identification and hybrid detection between C. finmarchicus and C. glacialis. Overall, Calanus glacialis were the most abundant throughout the winter, followed by C. finmarchicus and C. hyperboreus with only a few records of C. helgolandicus. The presence of C. glacialis, C. hyperboreus and C. ... : In the study described above, DNA was extracted from each specimen's antennules and used in a PCR reaction of 6 InDels. The dataset presented here contains the resulting genotypes, with the corresponding species ID attributed to each genotype. ...
