Abstract

fetched live from OpenAlex

Las montañas ocupan el 27% de la superficie terrestre y están presentes en casi todos sus biomas. Son sistemas que albergan una elevada proporción de especies endémicas y de climas fríos y aportan diversos servicios ecosistémicos. Sin embargo, a pesar de su topografía abrupta, las montañas no están exentas de los impactos del cambio global que, entre otras cosas, han afectado a la dinámica de las poblaciones de fauna, suponiendo en algunos casos retracciones que han incrementado su riesgo de extinción regional. Además, el rango de respuestas observado es amplio debido a los efectos de diversos factores extrínsecos (ambientales) e intrínsecos sobre las poblaciones. Este trabajo revisa las evidencias existentes de los impactos del cambio climático y las alteraciones en los usos del suelo sobre las poblaciones animales de montaña. Para ello, (1) se presenta una síntesis de las tendencias temporales de la climatología y de los usos del suelo, atendiendo a su variación a lo largo del gradiente altitudinal; (2) se describen los tipos de datos disponibles; (3) se sintetizan los patrones encontrados según el tipo de información analizada, así como los posibles mecanismos que explican su variabilidad; y (4) se proponen algunas posibles mejoras para la toma y la interpretación de los datos utilizados en el estudio del impacto del cambio global en poblaciones de montaña.

Not 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.
