New Zealand stoats provide an ark for genetic diversity

British stoats suffered a dramatic loss in genetic diversity in the 20th century but extinct British genes were preserved in the stoat population of New Zealand, a new study has found.The research reveals that stoats, which were introduced to New Zealand, have greater genetic diversity there, than in their native Britain. The results are unusual because introducing a species to a new area is usually associated with a loss in its genetic diversity. —> Read More
