Abstract

fetched live from OpenAlex

We karyotyped four lizards, Acanthosaura armata, Bronchocela cristatella, Calotes emma, and C. versicolor, all belonging to the tropical Asian clade of the family Agamidae. The karyotype of A. armata consisted of 12 metacentric macrochromosomes and 20 microchromosomes, whereas B. cristatella had 14 metacentric macrochromosomes and 20 microchromosomes. Except for the presence of 22 microchromosomes, the karyotypes of the two Calotes species were similar to that of A. armata. The 20 microchromosome state in the A. armata karyotype may have emerged in the ancestral lineage common to Gonocephalus robinsonii, whose karyotype also exhibits a 12M+20m format. Comparison of the present results with previously published information suggests the presence of cryptic taxonomic diversity in B. cristatella and C. versicolor.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
