Postglacial Vegetation at the Northern Limit of Lichen Woodland in Northwestern Québec
Bibliographic record
Abstract
Trois diagrammes polliniques provenant de la limite septentrionale de la pessiere à lichens du nord-ouest du Québec montrent des séquences en grande partie similaires durant l'Holocène. Après la déglaciation, survenue vers 6000 BP, la végétation de la région a été dominée par les plantes herbacées et arbustives de la toundra. Larix laricina, Populus et Juniperus ont aussi constitué des éléments importants du paysage. Un maximum d'AInus crispa et de Betula a été suivi par une période dominée par Picea. Dans le site le plus nordique, les forêts se sont ouvertes durant les 1000 dernières années en réponse au refroidissement néoglaciaire. Actuellement, seule l'épinette noire (Picea mariana) croît au nord-ouest du Québec, et les résultats laissent croire que l'épinette blanche (P. glauca) ne s'est jamais établie dans la région.

How this classification was reachedexpand
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.
