A test of the hypothesis that the spatial scale of effect of the landscape context on an ecological response increases with increasing time scale over which the response is regulated
Bibliographic record
Abstract
To detect an effect of landscape context on an ecological response one must measure the landscape variable at the appropriate spatial extent around the response, i.e. at its 'scale of effect'. However, it is not clear what determines this scale or if we can predict it a priori. One hypothesis is that the scale of effect increases with the temporal scale regulating the response. We tested this, comparing scales of effect of road density and forest amount on wood frog fecundity, abundance, and occurrence estimated from egg mass surveys of 34 ponds. We predicted the following order for scales of effect: fecundity < abundance < occurrence. Scales of effect were different for the three responses, but did not vary in the predicted order. This suggests that scales of effect cannot be predicted from the temporal scale regulating different responses and should thus be estimated empirically, rather than 'guestimated' a priori.

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.
