Abstract
Abstract Sympatric anuran species tend to differ in their temporal niche breadth and may also have considerable seasonal variation in diel activity patterns. We studied the temporal niche breadths of six anuran species during 24 consecutive months in an area of secondary forest at the Brazilian Atlantic Rainforest. Along hourly intervals, at each of three observation points along a stream, the number of calling males of Adenomera marmorata, Eleutherodactylus parvus, Physalaemus signifer, Aplastodiscus eugenioi, Scinax hayii and S. trapicheiroi was recorded. The influence of rainfall, air humidity and temperature on the variation in the niche breadth of each species was analysed. Mean niche breadth differed for all species. Scinax trapicheiroi had the broadest niche and S. hayii had the smallest. Temporal niche breadth varied seasonally for all species. Two species (E. parvus and S. hayii) showed strong variation in the temporal niche when compared to the other species. Eleutherodactylus parvus, A. eugenioi and S. hayii were significantly affected by rainfall, air humidity and temperature. Niche overlap among species pairs also varied annually with mean temporal niche overlap being greater during the rainy season than during the dry season.

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
