More about this episode

For USGS wildlife biologist Karyn Rode, tracking and tranquilizing polar bears from a helicopter are just the first thrilling steps in her research. After acquiring various samples from sleeping bears, Rode’s unique understanding of what they eat and how quickly they metabolize nutrients allows her to determine the condition of each bear. Working with a team of scientists from the U.S. Fish and Wildlife Service for nearly a decade, Rode’s monitoring of polar bear health has helped reveal how well populations are adapting to the rapidly warming Arctic.
