Comparison of two subspecies of Barbus capito in southern parts of Caspian Sea basin
Bibliographic record
Abstract
As for Barbus capito, two subspecies have been reported by L. S. Berg (1949) and other authors. To distinguish these two forms, 35 specimens were examined according to the main reported differences. All of these specimens have been collected in southern parts of Caspian Sea and are part of CMN (Canadian Museum of Nature) fish collection mainly collected by B. W. Coad. To analyze patterns of morphological variation in these specimens, PCA and DFA were used. The main differences were in head length, dorsal body length, caudal length and barbells length. There were no distinguishable characters for separating these two forms into two species. Considering other differences, the head length was not stable and could not be regarded as a distinctive character. However, in south of Caspian Sea, in addition to typical B. capito there were variations within this species with bigger head, longer caudal fork and longer pectoral.

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.
