Historical Mitogenomic Diversity and Population Structuring of Southern Hemisphere Fin Whales.
Peer reviewed: True Fin whales Balaenoptera physalus were hunted unsustainably across the globe in the 19th and 20th centuries, leading to vast reductions in population size. Whaling catch records indicate the importance of the Southern Ocean for this species; approximately 730,000 fin whales were h...
