Changes in the Composition of the Harvest in Three Polar Bear Subpopulations in the Western Canadian Arctic after the US Listing of the Polar Bear as a Threatened Species
Bibliographic record
Abstract
The 2008 United States (US) listing of the polar bear as a threatened species prohibits the importation of polar bear trophies into the US, significantly decreasing the number of Americans paying for guided polar bear hunts in Canada. We examined the numbers and composition of the harvest in three polar bear subpopulations—Northern Beaufort Sea, Southern Beaufort Sea, and Viscount Melville Sound—located in the Inuvialuit Settlement Region in the western Canadian Arctic in order to identify what happens when support for guided hunting is withdrawn. We find that there was no significant change in the number of polar bears harvested or in the sex composition of the harvest in the three subpopulations after the US listing. Over the 12-year study period, harvests in each subpopulation were always within the quota. The number of guided hunts decreased after the US listing, and the number of subsistence hunts increased in each subpopulation during this time. The number of bears harvested as a percentage of tags (hunting licenses to harvest one polar bear, the sum of which equals the annual quota) used was significantly higher in the Northern Beaufort Sea after the listing. This is because a tag issued for a guided hunt is considered used even if the hunt is unsuccessful, which is often the case, as hunters seek large male bears, whereas a tag issued for subsistence is re-issued until a successful harvest. We conclude that while the US listing and rapid decline in guided hunts did not affect the number of polar bears harvested, it did disrupt the Inuit cultural economy.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
