Wolverines, the largest terrestrial member of the weasel family, are difficult to find because they live in areas far from humans and human development. Therefore, not much is known about these mammals. Neither the current nor historical range of wolverines in the lower 48 States was well known before the work of these scientists. The scientists in this study wanted to accurately map the wolverines’ range over time and evaluate how climate change might be affecting their range.
