Is there a role for vision in the behaviour of sea lampreys (<i>Petromyzon marinus</i>) during their upstream spawning migration?
Bibliographic record
Abstract
This study found no evidence to support a role for vision in the behaviour of sea lampreys (Petromyzon marinus) during their spawning migration. Blindness had no affect on the migratory propensity of lampreys, and control and blinded animals moved upstream at the same rate. The diel activity pattern of control and blinded lampreys was identical in both the laboratory and field. Activity was mostly nocturnal, but lampreys in the field did show some daytime activity. Diel activity broke down when lampreys were unable to locate suitable daytime refuge, but blindness did not affect the willingness or ability of lampreys to do so in either the laboratory or field. Laboratory studies indicate that light avoidance is mediated by dermal photoreceptors located in the tail, but the data suggests that refuge sites are sought out before sunrise using tactile and possibly hydraulic cues. Thus, light-induced searching only occurs when the sites chosen at night do not provide adequate concealment after sunrise.

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.
