The effect of acute changes in temperature and light on the aerobic metabolism of embryos and yolk-sac larvae of turbot (<i>Scophthalmus maximus</i>)
Bibliographic record
Abstract
The effect of acute changes of temperature and light on the rates of oxygen consumption and ammonia excretion of developing embryos and yolk-sac larvae of turbot (Scophthalmus maximus) reared at 15 °C were studied. Short-term temperature adjustments of ±2 °C gave a mean Q10of 2.6 for the rate of oxygen consumption. Neither the presence nor the absence of light significantly influenced this response to acute temperature changes, despite light causing a significantly higher rate of oxygen consumption in the yolk-sac larvae between 9 and 12 days after fertilisation. This elevated metabolic rate in the presence of light occurred after pigmentation of the eyes and was probably due to activity associated with food-searching behaviour of this visual feeder. Similarly, for most development, the presence or absence of light and acute temperature adjustments did not cause any significant shift in the relative fraction of amino acids catabolised at 15 °C. However, on day 10 after fertilisation when peak rates of oxygen consumption occurred in the yolk-sac larvae exposed to light, the significantly elevated apparent nitrogen quotients indicated that greater amounts of amino acids were utilised for catabolic substrate oxidation.

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.
