Abstract

fetched live from OpenAlex

Abstract Vibrissaphora boringiae produces doughnut-shaped egg masses (i.e., circular mass with central depression) that are attached to the underside of submerged rocks in running water. The oviposition behaviour of this species was observed for the first time, and explains how egg masses were shaped. The male used the right hindlimb to push the eggs up to the bottom surface of the rock, while the pair rotated horizontally and counter clockwise. Three limbs of the female provided the support and power for the rotation. The male was positioned on the dorsal-left side of the female, and formed a rare asymmetric inguinal amplexus. This type of oviposition behaviour may be common in megophryid frogs that produce doughnut-shaped and circular egg masses.

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.
