Effects of a Diamond Mine on Tundra-Breeding Birds
Bibliographic record
Abstract
Breeding birds (songbirds, shorebirds, and ptarmigan) were surveyed at the Ekati Diamond Mine in Canada’s Northwest Territories from 1996 through 2003. Surveys were conducted on permanent, 25 ha mine and control plots. Five metrics (relative density of individual species, relative density of all birds, species richness using rarefaction curves, and species diversity using two indices) were used to assess potential impacts up to a distance of 1 km from the mine. Six species were more common on mine plots, and three were more common on control plots. Species diversity was slightly higher on mine plots when measured with Fisher’s alpha index. No other metrics suggested strong impacts. This study suggests that the mine has had a relatively limited impact on the upland breeding bird community within 1 km of the footprint but has provided habitat for at least one synanthropic bird species. Further monitoring of breeding birds on the tundra should include pre-development control data and demographic variables such as reproductive success and survival.

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.
