Assessing population structure and migratory patterns of White-throated Sparrow (Zonotrichia albicollis) breeding populations in western Canada.
Bibliographic record
Abstract
The objective of the present study was to investigate the genetic and migratory differences among White-throated Sparrow populations in western Canada in order to locate the presence of a migratory divide. Deuterium isotopes and molecular markers were used to assess the migratory differences between sparrows west (Central Interior BC) and east (Peace Region BC) of the Continental Divide. Head feather isotopes showed that both populations are overwinter wintering in either the Pacific Coast, New Mexico/Arizona or Colorado/Kansas areas. Microsatellites and mitochondrial markers did not show genetic structure among populations, however tail feather isotopes were significantly different. Analysis of migratory samples is congruent with Peace region birds migrating east of the divide. The Central Interior birds were not detected in any migratory monitoring locations. Data of the present study is congruent with a migratory divide and an east/west migration pattern between Central Interior and the Peace Region populations. --P. ii.

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.
