Abstract

fetched live from OpenAlex

Melanorivulus vittatus é endêmica do Brasil e com dois registros conhecidos em partes baixas da drenagem do rio Claro, bacia do alto rio Paraná, no estado de Goiás.Há dúvidas sobre a exata localização de sua localidade-tipo, que situa-se em algum ponto da rodovia que liga os municípios de Jataí e São Simão, talvez em trecho já não mais apropriado à sobrevivência da espécie.A extensão de ocorrência (EOO) atual foi calculada em 1.218 km² e a área de ocupação (AOO), em 156 km².Sabe-se que houve o declínio tanto da extensão de ocorrência quanto da área de ocupação.A principal ameaça que impacta a espécie é a agropecuária, que resultou na eliminação de 90% da cobertura de vegetação nativa original e consequente impacto nos cursos d'água da região.Considerando que a espécie só tem registro em duas pequenas microbacias, foram delimitadas duas localizações.Além disso, constata-se declínio continuado da qualidade de hábitat.Dessa forma, Melanorivulus vittatus foi categorizada como Em Perigo (EN) pelos critérios B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v).

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.
