Abstract

fetched live from OpenAlex

Ce rapport decrit la methodologie d’echantillonnage et les resultats de 15 milieux humides du Saint-Laurent (entre Cornwall et le lac Saint-Pierre) qui ont fait l’objet d’etudes en 1999, 2000 et 2001. Les bas niveaux extremes observes en 1999 et 2001 ont donne lieu a de fortes variations des communautes de plantes, dont on a tire profit dans l’analyse. Les resultats identifient six communautes de plantes situees entre les milieux plus « terrestres » (prairie humide) et les plus « aquatiques » (herbier submerge), constituant la frange de vegetation la plus sensible aux variations de niveau. Les communautes de plantes ont ensuite ete liees quantitativement aux differentes variables hydrologiques determinant leur presence. Ces informations permettront eventuellement de predire et de modeliser l’abondance et la distribution des principales communautes vegetales composant les milieux humides, constituant des habitats importants des especes animales. Enfin, ces connaissances permettront d’evaluer les effets environnementaux de differents scenarios de regularisation des debits sortants du lac Ontario vers le Saint-Laurent.

Not 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.
