Abstract

fetched live from OpenAlex

Abstract A posthatching developmental staging table for the larval phase of an ambystomatid salamander is provided for the first time. Stage boundaries are based upon limb development prior to the metamorphic transition and upon gill resorption during metamorphosis. Comparison to other published staging tables for salamanders of other families and anecdotal accounts of other ambystomatids is made, and similarities and differences are noted. These comparative data suggest that limb development may differ between species of Ambystoma in terms of the relative timing of hindlimb and forelimb morphogenesis.

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.
