Abstract

fetched live from OpenAlex

Les ecosystemes forestiers du Maroc sont fortement menaces par la pression anthropique. Les populations naturelles disjointes de pin maritime, Pinus pinaster Ait., sont particulierement concernees. Une reanalyse des donnees sur des allozymes de Wahid et al. (2004) par une methode Bayesienne de groupement (BAPS5) a permis d'identifier neuf reservoirs genetiques differencies parmi les onze populations restantes etudiees. Des populations a morphologies extremes sont presentes dans le Rif, ou la deforestation est la plus aigue. Une visite de plusieurs de ces populations en decembre 2006 a revele des menaces specifiques par des incendies frequents, une regeneration naturelle deficiente et une taille de populations tres faible (a Talaghine dans le Moyen Atlas, a Sidi Meskour dans le Haut Atlas). Une nouvelle strategie de conservation est urgente, pour la conservation in situ des peuplements de plus grande taille et les plus divergents: Punta Ceres, Madisouka et Tadiwine dans le Rif, Tamjout et Tamrabta dans le Moyen Atlas et Sidi Meskour dans le Haut Atlas. Il s'agit de favoriser la regeneration naturelle, le maintien de tailles de populations elevees et l'exclusion de materiel genetique allochtone. En fonction des moyens, une conservation des autres populations est recommandee et necessiterait des mesures complementaires ex situ pour les petites populations.

How this classification was reachedexpand

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
