Extreme suppression of aboveground activity by a food-storing hibernator, the eastern chipmunk (Tamias striatus)
Bibliographic record
Abstract
Eastern chipmunks ( Tamias striatus (L., 1758)) capitalize on pulsed production of storable seed from masting trees by accumulating large, long-term larder hoards in their burrow. Since this species does not accumulate fat, hoarded food is the sole source of energy used during hibernation and inactive periods. Because hoards can be very large, they offer chipmunks the possibility of forgoing aboveground foraging when seeds or nuts are not abundant on the forest floor. Here, we present evidence that at least 82 chipmunks in two different populations interrupted aboveground activity for 9–11 months when mast was not available. A large hoard of American beech ( Fagus grandifolia Ehrh.) nuts established during the preceding year appeared to allow these chipmunks to cease foraging for almost a full year when food availability was particularly low. This extended period of inactivity is among the longest reported for a hibernating mammal, and demonstrates complex interactions between past, current, and future resource availability in shaping the seasonal activity patterns of food-storing hibernators.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
