L’envahissement des milieux humides du Saint-Laurent par le roseau commun : une menace pour la biodiversité?
Bibliographic record
Abstract
La progression spectaculaire du roseau aux iles de Boucherville, dont la superficie des populations est passee de 1 a 33 ha entre 1980 et 2002 (Hudon et coll., 2005), suscite beaucoup d’interet. Preoccupes par la presence de plus en plus importante du roseau commun au Quebec, huit professeurs-chercheurs, rattaches a trois universites quebecoises (Laval, McGill et Montreal), ont cree le groupe Phragmites grâce a l’appui de plusieurs organismes gouvernementaux et non gouvernementaux. Ce groupe a joint ses efforts a ceux du parc national des Iles-de-Boucherville en vue d’etudier les modes de dissemination de la plante et repondre a plusieurs questions relatives a l'impact de cet envahisseur sur ses ecosystemes. Cette collaboration a ainsi donne lieu a l’elaboration de nombreux projets de recherche, dont la majeure partie a ete realisee par des etudiants-chercheurs. Puisque la principale roseliere du Quebec se trouve au parc national des Iles-de-Boucherville, ce parc a constitue un site tout indique pour la realisation de ces travaux, en voici donc un apercu

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.
