Introduction: Biology of the Canadian Arctic: A Crucible for Change in the 21st Century
Bibliographic record
Abstract
Canada is a northern country. Whether defined in terms of geography, climate, culture, or political boundaries, the North is an integral part of Canadian national identity and a strategic component of the country's future (Coates, 1995). Often defined as the half of the landmass and water that lies above the line of discontinuous permafrost, extending from northern British Columbia to Labrador, this vast region is home to only 1% of the human population in Canada. However, many other species are endemic to the North and many more seasonal migrants depend on northern environments for a significant part of their life history. The Canadian North, and indeed the entire circumpolar region, is a sensitive environment, facing rapid and unprecedented social, biophysical, and environmental changes. Several long-term, persistent, and pervasive changes are affecting northern environments simultaneously. Global climate change, ozone depletion, long-distance transport of contaminants, and rapid economic development have placed undue stress on terrestrial, freshwater and marine ecosystems. These stressors may have a wide range of ecologically significant effects on populations that will cascade upwards to affect the integrity of entire communities. World demand for energy supplies has increased interest in Canada's northern oil and gas fields with the resultant prospect of a pipeline snaking down the Mackenzie River becoming ever closer to reality. The Canadian North is also the world's third largest producer of diamonds, and mining for these precious stones now accounts for 20% of the Northwest Territories economic activity (McDonald, 2004). At the same time, new governance realities are being shaped by the settlement of aboriginal land claims and devolution of federal government responsibilities to the territories.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
