Abstract
Abstract The relationship between risk-taking behaviour and anti-predator morphology was studied in benthic threespine stickleback fish (Gasterosteus aculeatus) from Paxton and Priest Lakes on Texada Island, British Columbia, Canada. In general, Priest Lake benthics possess complete pelvic girdles and numerous lateral plates. In contrast, Paxton Lake benthics exhibit an apparent polymorphism in anti-predator morphology; some individuals possess complete pelvic girdles while others lack them entirely. Although phenotypes tended to differ in their willingness to risk exposure to a trout predator while foraging, the predicted positive relationship between risk-taking behaviour and anti-predator morphology was not observed. While 'girdled' Paxton individuals were more willing to forage in the vicinity of the predator than 'girdleless' Paxton individuals, the more heavily armoured Priest fish were intermediate in their risk-taking behaviour. These results suggest that the relationship between risktaking behaviour and anti-predator morphology may be influenced by differences between phenotypes in predation regime and life history.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
