La liebre europea, Lepus europaeus (Mammalia, Leporidae), especie invasora en el sur del Perú
Bibliographic record
Abstract
La liebre europea fue introducida entre finales del siglo XIX y comienzos del siglo XX a Argentina y Chile, y desde entonces ha avanzado a través de América del Sur. En 1983 la liebre había alcanzado el sur de Brasil, el departamento de Tarija en el sur de Bolivia y el río Copiapó en Chile, encontrándose ausente en el Perú. En los años 2002 y 2004 se observó varios ejemplares de liebre en estado silvestre en los departamentos peruanos de Tacna y Arequipa, hasta una altitud de 4300 m. Según entrevistas hechas a pobladores de esas zonas, la liebre habría llegado al Perú entre los años 1995 y 1998, lo que significa una velocidad de dispersión mínima de 44,34 km/año partiendo de Tarija. Los entrevistados dijeron no dar uso a la liebre y que ésta les trae problemas al consumir la vegetación. La presente nota es una alerta sobre la llegada de la liebre europea al Perú y los posibles efectos de su presencia.

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.
