Abstract
The photosynthetic and respiratory responses of two scleractinian coral species from Florida, Dichocoenia stokesii and Meandrina meandrites were examined in vitro under conditions of elevated turbidity for up to 3 weeks. Turbidity ranges of 7-9, 14-16 and 28-30 NTU were tested and compared to controls at 0-2 NTU. The highest range corresponds with the maximum allowed during construction in Florida coastal waters. No differences were found between control and the 7-9 NTU groups. However, both species exhibited significant changes in P:R ratio after 2-3 days in both the 14-16 and the 28-30 NTU ranges compared to controls. Mucus production was clearly evident in the higher turbidity ranges. Exposure to 28-30 NTU depressed the P:R ratio to below 1.0, a level that was maintained for the 21-day duration of the experiments. Light was never less than the saturation value of either species, and no change in light quality was observed as a function of turbidity. Since no significant differences were observed in gross photosynthetic oxygen production among any of the treatment or control groups, the turbidity-related change observed in the P: R ratio appears due to increased respiration, rather than decreased photosynthesis. These results suggest that adherence to turbidity-related water quality standards as presently defined in Florida, may result in short term stress and long term decline in at least some coral species.

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; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
