Abstract
Although it has been proposed that tail shapes could be used as the basis for ecologically useful functional groups of nematodes, the proposition has not been tested.We used data from three sites in the deep North Atlantic for such a test.In a prétest, we found that nematode functional groups based on buccal morphology differed significantly in their proportional représentation among the sites, indicating that for nematodes the sites differed ecologically.Results of similar tests involving tail-shape groups were significant, indicating that there is ecological information in the tail-shape groups, and a further test revealed that the information in the shape of the tail was not a simple reflection of information in the buccalmorphology groups.Distribution of functional groups formed by combining tail shape and buccal morphology also differed significantly among sites.We conclude that both the tail-shape and buccal-morphology-by-tail-shape approaches hold promise for the ecological analysis of deep-sea nematode assemblages.RÉSUMÉ -Bien que la forme de la queue des Nématodes ait été proposée pour constituer des groupes fonctionnels sur le plan écologique, cette hypothèse n'a pas été testée.Nous avons utilisé des données provenant de trois sites de prélèvements de l'Atlantique nord profond pour de tels tests.Dans un test préliminaire, nous avons trouvé que les groupes fonctionnels de Nématodes basés sur la morphologie buccale présentaient des différences significatives dans leurs proportions relatives entre les sites, ce qui montre que les sites sont différents sur le plan écologique pour les Nématodes.Les résultats d'analyses similaires impliquant les groupes constitués à partir de la queue sont significatifs, indiquant qu'il existe une information d'ordre écologique à partir de ces groupes et une analyse ultérieure montre que l'information provenant de la forme caudale ne correspond pas à une simple redondance de l'information obtenue à partir des groupes basés sur la morphologie buccale.La distribution des groupes fonctionnels obtenus en combinant la forme caudale et la morphologie buccale diffère également de façon significative entre sites.En conclusion, les deux approches, forme caudale et morphologie buccale -forme caudale seront intéressantes à exploiter lors des analyses écologiques des communautés de Nématodes profonds.

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; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
