King penguin population on Macquarie Island recovers ancient DNA diversity after heavy exploitation in historic times
Historically, king penguin populations on Macquarie Island have suffered greatly from human exploitation. Two large colonies on the island were drastically reduced to a single small colony as a result of harvesting for the blubber oil industry. However, recent conservation efforts have resulted in t...
