Abstract
Los tiburones tigre (Galeocerdo cuvier) son una de las tantas criaturas que habitan los mares tropicales. Como depredadores marinos, los tiburones tigre cazan sus presas de manera activa, incluyendo crustáceos, peces, serpientes, tortugas, aves y mamíferos, pero además, estos animales son carroñeros facultativos, lo que les permite complementar la dieta con restos de animales muertos, tales como restos de ballenas. ¿Pero quién imaginaría que los tiburones tigre también se alimentan de aves terrestres? Pues un estudio reciente publicado en la revista Ecology demostró que los tiburones tigre colectados en la costa de Mississippi-Alabama, Estados Unidos, en el Golfo de México, se han estado alimentando de aves terrestres tales como golondrinas (Hirundo rustica), tiránidos (Tyrannus tyrannus), sotorreyes (Troglodytes aedon), parúlidos (Geothlypis trichas), ictéridos (Sturnella magna), gorriones (Melospiza georgiana), palomas (Zenaida asiatica) y carpinteros (Sphyrapicus varius), entre otras —hasta once especies de aves terrestres en total—.--LEER MÁS--

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.
