When the presence of a vateritic otolith has morphological effect on its aragonitic partner: trans-lateral compensation induces bias in microecological patterns in one-side-only vateritic otolith
Bibliographic record
Abstract
In many teleost species, aragonite is the normal form of calcium carbonate in sagittal otoliths. In the case of one-side-only (OSO) vateritic otoliths (abnormal crystalline structure), morphological investigations are systematically conducted on the other side. The implicit assumption is that the morphological information on the aragonitic side remains unaffected by the presence of vaterite on the other side. However, the extent to which this assumption is met has never been explored. Applying geometric morphometrics on experimentally maintained brown trout (Salmo trutta) revealed incongruent variational patterns and mean shape differences between OSO and two-sided aragonitic otoliths, possibly due to trans-lateral compensation to preserve their auditory function. More specifically, fully aragonitic pairs of otoliths are more prone to exhibit microecological variations compared with OSO vateritic pairs. Simulation emphasizes the relative robustness of both micro- and macroecological effects until a high proportion of OSO vateritic otoliths is used. Given that otolith shape analysis provides a useful basis for stock separation, care should be taken when interpreting otolith shape in the presence of vateritic otoliths.

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.
