• Hair Collection

Polar Bear Hair Trap and DNA Sampling

The video details the use of a polar bear hair trap, described as a plywood box equipped with two metal brushes. A trail camera is also attached to this trap. The primary purpose of this setup is to collect hair samples from polar bears. These hair samples are crucial for DNA analysis, which allows researchers to identify individual bears and understand the population dynamics on the coast and island chains. The goal is to initiate this data collection and monitor the polar bear population.

Hair Trap Efficacy and Hair Collection

Upon inspection, the hair trap is found to be destroyed. However, the metal brushes are functioning as intended. Despite the damage to the trap itself, sufficient hair has been collected. This collected hair is then processed for DNA sampling.

Importance of Video Samples

The video also highlights the value of video samples obtained from the trail camera. These video recordings are useful for assessing the size of the polar bears, providing additional data for population assessment.

Conclusion

The polar bear hair trap, despite being destroyed, successfully collected hair samples for DNA analysis. This method, combined with trail camera footage for size estimation, is a vital tool for monitoring polar bear populations and understanding their genetic makeup on the coast and island chains.
