Changes in the reproductive behaviour of the endangered Newfoundland marten (<i>Martes americana atrata</i>): implications for captive breeding programs
Bibliographic record
Abstract
Behavioural changes associated with reproduction were studied in captive Newfoundland martens (Martes americana atrata), an endangered species. Patterns of scent-marking and behavioural interactions were recorded before and after a male was introduced to two females. After introduction of the male, marking by the receptive female increased, whereas the nonreceptive female marked less and became less active. Activity and marking bouts were significantly correlated throughout the day for the male and the receptive female, and they often marked in the same locations. The male marked more frequently when the receptive female was active and the female's marking was often associated with behavioural interactions. These findings suggest a major female influence on male marking and activity and suggest that marking may facilitate social interaction. In the spring following this study, the receptive female successfully whelped a litter, the first to be conceived and born in this captive breeding program. The results of this study may help establish successful protocols for captive breeding programs, and thus aid efforts to conserve this endangered species.

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.
