Effect of Mesodinium rubrum (= Myrionecta rubra) on the action and absorption spectra of phytoplankton in a coastal marine inlet
Bibliographic record
Abstract
This study, carried out at a single station in the Bedford Basin (Nova Scotia, Canada), examined time-dependent changes in the physical and chemical conditions of the waters with associated changes in species composition and some photosynthesis properties of phytoplankton. The sampling period covered late summer months (August and September) and fall months (October to December). Changes in the water conditions were found to influence species composition, which in turn had an effect on the shapes and amplitudes of the action and absorption spectra of phytoplankton, and on the maximum quantum yield of photosynthesis. The most remarkable change was observed in October during a bloom of Mesodinium rubrum, a ciliate harbouring photosynthetic endosymbionts rich in phycobilins. The presence of M. rubrum yielded atypical shapes of the measured photosynthetic action spectra; furthermore, other photosynthesis properties changed significantly. These results demonstrate that the presence of certain pigments in the water column may be associated with a marked shift from what may be considered typical (representative) photosynthesis properties of phytoplankton.

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.
