Abstract
catalaPresentem sinteticament una part dels resultats fitogeografics descrits en la tesi doctoral de l’autor. En aquest cas, caracteritzem i validem diversos sintaxons de prats de dall higrofils (ord. Deschampsietalia cespitosae) i mesohigrofils (ord. Trifolio-Hordeetalia) del nord-est de Catalunya (incl. NE d’Espanya i SE de Franca) i de l’Europa occidental. En total, s’han estudiat 22 sintaxons a partir de taules sintetiques i analisis factorials de correspondencies: 1 classe (Molino-Arrhenatheretea), 2 ordres (Deschampsietalia cespitosae; Trifolio-Hordeetalia), 4 aliances (Oenanthion fistulosae; Ranunculo-Oenanthion; Oenantho-Gaudinion all. nova; Alopecuro-Trifolion all. nova), 4 associacions i 11 subassociacions (Baldellio-Oenanthetum subass. alopecuretosum subass. nova; Gaudinio-Arrhenatheretum subass. narcissetosum, subass. festucetosum comb. nova, subass. lotetosum subass. nova, subass. lolietosum subass. nova; Ophioglosso-Oenanthethum subass. typicum, subass. oenanthetosum comb. nova; Geranio-Festucetum stat. novus subass. typicum, subass. arrhenatheretosum comb. nova, subass. gratioletosum subass. nova, subass. caricetosum subass. nova). Entre les noves aportacions fitosociologiques, cal destacar la descripcio de dues noves aliances, i la separacio dels prats de dall mesohigrofils de la Mediterrania catalanoccitana adscrits tradicionalment al Gaudinio-Arrhenatheretum (all. Arrhenatherion o Brachypodio-Centaureion segons l’autor, ord. Arrhenatheretalia) en dues associacions (Gaudinio-Arrhenatheretum i Geranio-Festucetum), aixi com la seva assignacio a l’alianca Oenantho-Gaudinion i a l’ordre TrifolioHordeetalia (class. Molinio-Arrhenatheretea) EnglishA summary of part of the phytogeographic results described in the author’s PhD thesis is presented here. Several syntaxa from hygrophilous (ord. Deschampsietalia cespitosae) and mesohygrophilous (ord. Trifolio-Hordeetalia) hay meadows of north-eastern Catalonia (incl. NE of Spain and SE of France) and western Europe, are characterized and validated. In total 22 syntaxa have been studied, based on synthetic tables and correspondence factor analyses: 1 class (Molino-Arrhenatheretea), 2 orders (Deschampsietalia cespitosae, TrifolioHordeetalia), 4 alliances (Oenanthion fistulosae; Ranunculo-Oenanthion; Oenantho Gaudinion all. nova; Alopecuro-Trifolion all. nova), 4 associations and 11 subassociations (Baldellio-Oenanthetum subass. alopecuretosum subass. nova; Gaudinio-Arrhenatheretum subass. narcissetosum, subass. festucetosum comb. nova, subass. lotetosum subass. nova, subass. lolietosum subass. nova; Ophioglosso-Oenanthethum subass. typicum, subass. oenanthetosum comb. nova; Geranio-Festucetum stat. novus subass. typicum, subass. arrhenatheretosum comb. nova, subass. gratioletosum subass. nova, subass. caricetosum subass. nova). Among the new phytosociological contributions, it is worth noting the description of two new alliances and the division of the mesohygrophilous hay meadows of the Catalan-Occitan Mediterranean traditionally assigned to the Gaudinio-Arrhenatheretum (all. Arrhenatherion or Brachypodio-Centaureion according to the author, ord. Arrhenatheretalia) in two associations (Gaudinio-Arrhenatheretum and Geranio-Festucetum), as well as their assignment to the Oenantho-Gaudinion alliance and to the Trifolio-Hordeetalia order (class. Molinio-Arrhenatheretea)

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.
