Reduced predation on roadside nests could compensate for additional road mortality in road-adjacent painted turtle (Chrysemys picta) populations.
Bibliographic record
Abstract
Turtles are killed on roads, yet there is little evidence of negative road effects on abundances.We hypothesized that reduced predation of roadside nests could compensate for adult road-kill.To test this, we quantified the relative differences in predation of artificial painted turtle (Chrysemys picta) nests near and far from roads, in a field experiment controlling for potentially confounding differences between sites.We then estimated how much adult road-kill could be compensated for by an increase in roadside nest success using Population Viability Analysis (PVA).Linearly arranged roadside nests had a 26% higher survival rate than non-road nests in a "natural" (clumped) configuration.This lead to an estimate that 3-6% annual adult road kill can be compensated for by the lower nest predation.This suggests that compensation for adult road kill via predation release is a plausible explanation for the lack of road effects on turtle abundances.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
