Avian Mixed Function Oxidase Induction as a Monitoring Device: The Influence of Normal Physiological Functions
Bibliographic record
Abstract
This chapter examines four specific examples of studies in wild birds, the role of the sexual cycle in the modification of MFO activity and consequently the importance of considering this aspect in planning biomonitoring. The four examples are the seasonal variations in the activity of hepatic aldrin epoxidase in a population of wood pigeon (Columba palumbus) in a relatively unpolluted area of central Italy, the seasonal variation of the same enzyme in the yellow-legged herring gull (Larus argentatus cachinnans) from northern Italy, changes in the activity of several MFO enzymes during the breeding cycle of the herring gull (Larus argentatus smithsonianus) and a comparison with activity found during the winter in Eastern Canada, and the different levels of aldrin epoxidase activities and PCB concentrations in the liver of the yellow-legged herring gull collected during the reproductive and post-reproductive periods in several polluted areas of Italy.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
