Abstract
Geographic variation in body size of Sylvilagus floridanus was investigated from 3 climatically different and disjunct regions of the range of this species (region 1, northeastern United States and southern Canada; region 2, southeastern United States; region 3, southwestern United States and northern Mexico). On a rangewide scale, body size decreased from east to west and less strongly north to south, consistent with Bergmann's rule, and was associated most strongly with variability in winter precipitation. On a regional scale, body size decreased from northwest to southeast in region 1 and southwest to northeast in region 3. We detected no trend in region 2. Large body size in region 1 was found in cold and dry environments. Body size in region 3 increased with cooler and wetter summer environments, high elevations, and low variability in winter precipitation. Bergmann's rule was supported within region 1 but not in region 2 or 3. Directions and magnitudes of trends in body size appear to depend on severity of climate; the 2 most climatically stressful regions (1 and 3) had stronger climatic correlations than region 2.

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
