Seasonal changes in the lipids of <i>Mysis mixta</i> (Mysidacea) from the hyperbenthos of a cold-ocean environment (Conception Bay, Newfoundland)
Bibliographic record
Abstract
Total lipid (TL) and lipid class composition of Mysis mixta Lilljeborg from 240-m depth in a cold-water marine bay were studied throughout 1999 and 2000. The objective was to relate the seasonal lipid dynamics in an abundant and lipid-rich hyperbenthic species to its life cycle and to the annual phytoplankton bloom. Mysis mixta accumulated high levels of lipid reserves similar to those reached by other cold-water zooplankton. Greatest accumulation occurred in maturing females and males upon initiation of the spring bloom and continued for 6 months. The lowest TL level was ~5% dry mass (DM) in small juveniles, post-spawned males, and spent females, and the highest level was 32% DM in females approaching full maturity (overall content range 0.316 mg·mysid1). Most females accumulated lipid for 2 years before spawning, although a few females spawned 7 months early with a very low TL content. Seasonal variation in TL resulted primarily from net changes in triacylglycerol, the predominant neutral lipid. Seasonal and interannual variation in TL quantities in individuals and in areal concentrations of lipid in the hyperbenthic population indicates a strong trophic link between M. mixta and the pelagic production cycle.

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.
