Cambios en la dieta, a largo plazo, de la lechuza común (Tyto alba, SCOPOLI 1769) en tres localidades de las provincias de Badajoz, Madrid y Toledo (España).
Bibliographic record
Abstract
En este estudio se analizan los cambios en la dieta de la lechuza común (Tyto alba, SCOPOLI, 1769) durante los últimos 40 años. Para ello, se compararon los resultados procedentes del análisis de egagrópilas “antiguas” (1976-1977) y “modernas” (2019 - 2020) en tres localidades de España, situadas en las provincias de Badajoz, Madrid y Toledo. Los resultados de los análisis indican la disminución del consumo de insectos y de musarañas (pequeños mamíferos insectívoros, F. Soricidae) en las tres localidades. Las disminuciones de frecuencia en la dieta de insectos y musarañas parecen compensarse por un mayor consumo de aves y roedores (O.Rodentia). Se sugiere que la intensificación agrícola pudiera estar relacionada con la pérdida de insectos y musarañas en la alimentación de la lechuza.

How this classification was reachedexpand
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.
