Environmental and microstructural controls of short-term shell degradation in temperate, macrotidal environments
Bibliographic record
Abstract
L’état de préservation des coquilles d’organismes marins dépend directement des conditions environnementales dans lesquelles elles se dégradent. Cette étude a pour but de déterminer les conditions de dégradation progressive de coquillages (Mytilus edulis) et de cristaux abiotiques d’aragonite déployés à l’interface eau-sédiment ainsi qu’enfouis (à 10-20 cm) durant treize mois, dans les zones haute et moyenne d’un marais salant, une plage et une crique de la Baie de Fundy (NB, Canada). Les changements macroscopiques, microscopiques et de masse sont discutés relativement aux conditions environnementales. Nos résultats montrent que: 1) la dégradation et les processus agissent très tôt après la déposition, et produisent des changement d’état significatifs en deçà de 13 mois post-mortem. 2) Dans les environments ci-dessus, la mue des tablettes de nacre de la surface de la coquille est le processus le plus efficace, suivi par la bioérosion, et la macération. 3) La dissolution joue un rôle secondaire durant la dégradation précoce des coquillages.

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.
