Analysis of Mitochondrial Dna of Pacific Black Brant (branta Bernicla Nigricans)
Bibliographic record
Abstract
Brant (Branta bernicla) have become the object of increased concern to managers of waterfowl populations.The numbers of wintering Brant have decreased markedly from a peak of 55,000 wintering birds in the United States in 1958 to approximately 5,000 in 1972 (Management Plan for Pacific Coast Brant 1981).Corresponding reductions in the numbers of breeding Brant in Alaska have also occurred (Lensink 1987).The numbers of wintering birds in traditional Brant areas in British Columbia, Washington, Oregon, and California have declined during periods when the numbers of wintering birds in Mexico have increased.Together, these observations imply that a variety of factors may influence Brant numbers in any locale throughout the year.Reductions in the number of Brant that traditionally winter in Canada and the western United States may simply be associated with habitat deterioration or disturbance, which forced the birds to winter farther south in Mexico.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
