Choosing the Safest Route: Frog Orientation in an Agricultural Landscape
Bibliographic record
Abstract
Orientation is a key component to successful movements between habitats. We hypothesized that barren agricultural landscapes hinder the ability of frogs to orient and move between habitats. Specifically, we predicted that when presented with a choice between a short route through a hostile environment and a longer but safer route, individuals would select the one that entails the least risk. During a field experiment, we translocated 104 Edible Frogs (Rana klepton esculenta) into a recently harrowed field according to two treatments: the distance to their pond of origin (5–70 m) and the distance to a wooded hedgerow (10–60 m). The frogs' ability to orient toward the pond decreased with pond distance and increased with distance to the hedgerow, but we did not detect interactive effects. In addition, frogs were more successful in orienting toward the pond under high wind conditions. We have shown that both the configuration of the landscape and weather variables influence the movement behavior of amphibians in agricultural settings, and these may have important implications for population persistence.

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.
