Wrangel Island Polar Bear Study

This collaborative study is now on pause due to the war in Ukraine.

Why it Matters

Wrangel Island, Russia, is a critical resting and denning location for the data-deficient Chukchi Sea polar bears.

The Impact

Using ground-based observations and non-invasive genetic samples (hair traps), researchers were:

  • examining gene flow, diversity, and population dynamics to improve our understanding of how these bears fit into global polar bear diversity

  • working to improve our understanding of how Wrangel Island’s bears were handling the effects of longer ice-free seasons due to climate warming
