Why do we track polar bears?
This important work helps us to understand the impact that climate change, toxic pollution and other threats are having on different polar bear populations. An important part of polar bear research is understanding the movements of the bears, particularly in relation to sea ice.
To understand how they travel
Over time this information reveals changes and adaptations. For example, in years when there is less sea ice, it will tell us where bears go and how they adapt.
To monitor health
- measuring Its length and weight
- taking samples of blood, fat, hair, and other tissues to identify any toxic contamination
- estimating its age. Like the rings of a tree, the polar bear's teeth have thin layers of bone that show its age. Scientists pull a small tooth, located just behind the large canine teeth and of no use to the bear.
