Genetic examination of historical North Atlantic right whale (Eubalaena glacialis) bone specimens from the eastern North Atlantic: Insights into species history, transoceanic population structure, and genetic diversity

Species monitoring and conservation is increasingly challenging under current climate change scenarios. For the North Atlantic right whale (Eubalaena glacialis) this challenge is heightened by the added effects of complicated and uncertain past species demography. Right whales once had a much wider...

Following mtDNA species identification, we obtained 15-locus nuclear microsatellite profiles from a subset of eight specimens and compared these to contemporary data from animals remaining in the western North Atlantic population.

Moderate mtDNA and nuclear differentiation between the two regions was identified (mtDNA: FST = 0.0423, ΦST = 0.041; nuclear DNA: FST = 0.024). Interpretation of the relationships between animals in the two regions is not simple, and this research highlights the difficulty in conducting such assessments in species with complex histories of unknown structure prior to extensive exploitation. publishedVersion Article in Journal/Newspaper Eubalaena glacialis Faroe Islands Iceland North Atlantic North Atlantic right whale University of Bergen: Bergen Open Research Archive (BORA-UiB) Faroe Islands Marine Mammal Science 38 3 1050 1069
