Abstract
The Range Database contains data, at a low spatial resolution (50 x 50 km), on the Eurasian historical distribution of brown bear, areas of current presence and areas which were occupied in the past but where the species has been extirpated. We used 10 different sources of historical data for brown bear, below we report the area of study, the map/figure/data within the publication and the century: for Spain we used data obtained from “Anotaciones al “Libro de la Montería” del Rey Alfonso XI. “(Valverde 2009) (XIV Century), for North West of Spain (Galicia) the figure 1 from “A conservación do oso pardo en Galicia” (Naves & Fernández-Gil 2017) (XVIII Century), for North of Spain (Cantabrian Mountains) the figure 6.16 from “Bears. Status Survey and Conservation Action Plan” (Servheen et al. 1999) (XIX Century), for Portugal we used figure 1 from “Research trends and geographical distribution of mammalian carnivores in Portugal” (SW Europe) (Bencatel et al. 2018) (XVII Century), for Portugal we also used the figure 1 from “Historical presence of Brown bear in Portugal and evidence of its relation with human communities” (Álvares & Domingues 2010) (XVI-XVIII Centuries), for France we used the data from figure “Répartition de lÓurs brun en France” from the “Encyclopédie des carnivores de France”(Parde & Camarra 1992) (XV-XVI Centuries), figure 1 from “A habitat model for brown bear conservation and land use planning in the central Apennines” (Posillico et al. 2004) (XVI-XVIII Centuries), for the former Yugoslavian countries from figure 6.19 from “Bears. Status Survey and Conservation Action Plan” (Servheen et al. 1999) (XIX Century), for Greece from figure 6.8 from “Bears. Status Survey and Conservation Action Plan” (Servheen et al. 1999) (II Century), and the historical distribution for brown bear for Eurasia from the IUCN Red List (McLellan et al. 2017) (XVI-XX Centuries).

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.
