Abstract
Prey animals may mediate the intensity of their behavioural responses to predators to reflect their risk of predation. However, in the absence of an overt (observable) behavioural response to a particular predation-risk cue, we need to ask whether or not prey animals are still using the cue to assess predation risk. Behavioural responses that are not readily observable within the time frame of the experiment are considered covert. In this study we exposed juvenile rainbow trout, Oncorhynchus mykiss, to varying concentrations of conspecific chemical alarm cue to determine their observable response threshold. In a subsequent experiment we exposed the trout to alarm-cue concentrations above and below their behavioural-response threshold and allowed them to interact with an unknown predator (northern pike, Esox lucius). Trout exposed to concentrations below the observable response threshold were able to evade the predator equally as well as trout exposed to alarm-cue concentrations above the observable response threshold. This study illustrates the sophistication with which prey animals employ chemosensory risk assessment. We must use caution when relying on overt behavioural responses for assessing whether prey are utilizing specific cues to mediate their risk of predation.

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
