Dose and dose-rate dependency in the mortality response of Calanus finmarchicus embryos exposed to ultraviolet radiation
Bibliographic record
Abstract
In previous work, we reported that embryos of Calanus finmarchicus exposed to artificial ultraviolet-B (UV-B) radiation exhibited high wavelength-dependent mortality.The strongest effects occurred under exposures to wavelengths below 312 nm and, at the shorter wavelengths (< 305 nm), UV-B-induced mortality was strongly dependent on cumulative exposure (i.e.dose).In the experiments reported here, we tested (for C. finmarchicus) the principle of reciprocity -that is, was the effect of cumulative UV dose the same regardless of the dose rate at which it was delivered?Dose rate had no discernible effect on the proportion of live C. finmarchicus nauplii recovered from eggs exposed to 3 different UV doses: reciprocity held.The doses and dose rates administered were ecologically relevant.However, the issue of UV dose versus dose-rate effects on marine organisms requires further investigation -at a broad range of dose and dose rates and for different exposure durations, preferably under natural sunlight.

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.
