The great auk was once abundant and distributed across the North Atlantic. It is now extinct, having been heavily exploited for its eggs, meat, and feathers. We investigated the impact of human hunting on its demise by integrating genetic data, GPS-based ocean current data, and analyses of population viability. We sequenced complete mitochondrial genomes of 41 individuals from across the species’ geographic range and reconstructed population structure and population dynamics throughout the Holocene. Taken together, our data do not provide any evidence that great auks were at risk of extinction prior to the onset of intensive human hunting in the early 16th century. In addition, our population viability analyses reveal that even if the great auk had not been under threat by environmental change, human hunting alone could have been sufficient to cause its extinction. Our results emphasise the vulnerability of even abundant and widespread species to intense and localised exploitation.

Kan grønlandsk socialpolitik være sexet? Mit oplæg i kronikken er ja. Det er sexet at arbejde for at gode minder bliver til positive fremtider. Det er sexet, at der er en gennemgående tanke fra politik til handling - således at det arbejde der udføres rundt om i kommunerne hænger sammen med langsigtede socialpolitiske visioner.
