Pluie was one of the first animals to wear a satellite tracking collar with global readout, meaning her movements could be tracked no matter how far she went - and did she every go far!  Dr. Mark Hebblewhite tells how the incredible movements of this one wolf inspired a new effort to protect large landscapes, from Yukon to Yellowstone (Y2Y), needed by large carnivores.  She also was featured on an episode of the West Wing.
