Abstract
Reduced torpor expression by hibernating mammals is often attributed to physiological constraints that limit their hibernation ability but may instead reflect adaptive, plastic responses to surplus energy availability. We evaluated this hypothesis by supplementing the food hoards of free-ranging eastern chipmunks (Tamias striatus) before hibernation and then documenting their use of torpor during the subsequent winter. In both years of study, chipmunks that received additional food were euthermic more than twice as frequently as nonsupplemented individuals. Furthermore, when food-supplemented individuals did express torpor, their minimum collar temperature was 5 degrees -10 degrees C warmer than nonsupplemented animals. These results indicate that reduced torpor expression by hibernators can result from an absence of energetic necessity rather than a lack of physiological capability and suggest that even endotherms sequestered in a hibernaculum may benefit from maintaining an elevated body temperature whenever possible.

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
