Abstract
Etudes de l'alternance de morphotypes chez Monoraphidium sp. (Selenastraceae, Chlorophyta). Les reponses morphologiques a differents facteurs environnementaux ont ete etudies chez l'algue verte Monoraphidiumsp., isolee d'un etang a Changhua city a Taiwan. L'algue presente des cellules fusiformes et spheriques quand elle est cultivee en laboratoire. Des temperatures differentes (20 °C, 25 °C et 30 °C), des modifications du pH initial du milieu (de 6.22 a 9), et des remplacements du milieu au 25 e jour, derniere phase stationnaire, ont ete testees pour determiner les facteurs qui affectent l'alternance de morphotype chez cette algue verte. Durant ces experiences physiologiques, les cellules fusiformes ont prolifere dans le milieu frais et se sont transformees en cellules spheriques dans le vieux milieu. Des lignees spheriques sont observees dans toutes les experiences physiologiques. Lors des tests de temperature, d'une part, les cellules spheriques sont significativement plus larges a 30 °C qu'a 20° ou 25 °C (P 0.05). Le remplacement du milieu lors de la derniere phase stationnaire, entraine une alternance drastique entre les morphotypes fusiformes et spheriques. Ces resultats suggerent que le contenu du milieu est le principal facteur influencant l'alternance de morphotype. En se basant sur ces experiences et sur ces observations detaillees, il est propose un modele schematique de l'alternance de morphotype chez Monoraphidium sp.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
