Molecular Phylogeny of the Genus Acanthosaura (Agamidae)
Bibliographic record
Abstract
A 900bp fragment of mitochondrial cytochrome b was sequenced from 63 specimens of the arboreal agamid lizard genus Acanthosaura from Vietnam, Laos, Myanmar (Burma), Thailand and Malaysia, representing all four currently recognized species. A hypothesis of maternal relationships was generated based on a maximum parsimony analysis of 44 different haplotypes. Pseudocalotes and Calotes were used as outgroup taxa. The genealogical analyses of the cytochrome b sequences recovered four lineages represented by A. armata, A. capra, A. crucigera, and A. lepidogaster. A fifth lineage consisted of one specimen from Ngoc Linh, Vietnam that was considered to be A. lepidogaster; however, recognizing it as such would render A. lepidogaster paraphyletic. Acanthosaura crucigera consisted of two clades. One of these clades contains cysteine in a portion of its cytochrome b, and is the sister group of all other species of Acanthosaura. In turn, the second clade of A. crucigera formed the sister group of A. armata, A. capra, and A. lepidogaster. A clade containing A. armata, A. capra and the sample from Ngoc Linh, Vietnam was the sister group to A. lepidogaster.

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.
