Conservation implications of elucidating the Korean wolf taxonomic ambiguity through whole-genome sequencing

The taxonomic status of the now likely extirpated Korean Peninsula wolf has been extensively debated, with some arguing it represents an independent wolf lineage, Canis coreanus. To investigate the Korean wolf genetic affiliations and their taxonomic implications, we sequenced and analysed the genomes of a historical Korean wolf dated to the beginning of the 20th century, and a captive wolf originally located at the Pyongyang Central Zoo. Our results indicated that the Korean wolf bears similar genetic ancestry to other regional East Asian populations, therefore suggesting it is not a distinct taxonomic lineage. We identified regional patterns of wolf population structure and admixture in East Asia with potential conservation consequences in the Korean Peninsula and on a regional scale. We find the Korean wolf has similar diversity and inbreeding to other East Asian wolves. Finally, we show that, in contrast to the historical sample, the captive wolf is more genetically similar to wolves from the Tibetan Plateau, hence, Korean wolf conservation programs might not benefit from the inclusion of this specimen. ### Competing Interest Statement The authors have declared no competing interest.
