Effect of season, sex and reproduction on zinc concentration in the soft tissues of Meretrix casta (Chemnitz) (Mollusca: Bivalvia) collected from Vellar Estuary, Porto Novo, India
Bibliographic record
Abstract
The investigation was undertaken to determine the impact of ecological and biological factors on the bio-accumulation of zinc in Meretrix casta collected from Vellar Estuary. The concentration of zinc in water, sediment, whole animal tissues and different soft body parts, such as adductor muscle, foot, mantle, gill, gonad and digestive diverticula of both male and female, were analysed separately. A high concentration of zinc was discernible during the monsoon, whereas it was low during summer. The metal concentration in the sediment was higher than in the water and body tissues. Among the body tissues, gill tissues showed high values followed by the mantle, digestive diverticula, gonad, foot and adductor muscle. A statistical analysis revealed a significant positive correlation between zinc concentration in body tissues and ambient medium. A significant negative relationship was encountered between salinity and zinc concentration in animal body tissues.

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.
