Biochemical and histopathological changes induced by sodium monofluoroacetate (1080) in mallard ducks
Bibliographic record
Abstract
Public concern over inadvertent kills of native birds following largescale aerial poisoning operations for possum has highlighted deficiencies in information concerning the effects of 1080 on nontarget species In this study biochemical and histopathological changes were measured in adult male mallard ducks (Anas platyrynchos) dosed orally with 1080 The toxin was quickly absorbed into the blood and distributed to the cardiac tissue The time taken to reach maximum 1080 concentrations in these tissues corresponded closely with the onset of clinical signs of toxicosis Tissue and serum citrate accumulation is a direct result of 1080induced inhibition of the Krebs Cycle enzyme aconitate hydratase Histopathological lesions indicated that skeletal muscle was a target organ for 1080induced damage in birds Dosedependent increases in serum creatinine kinase (CK) and aspartate aminotransferase (AST) were consistent with extensive muscle necrosis Skeletal muscle may be a unique avianspecific target organ for 1080

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.
