Abstract

fetched live from OpenAlex

The first documented evidence of the porbeagle shark, Lamna nasus (Chondrichthyes, Lamnidae) in the area of the North Scotia Ridge (Southwest Atlantic) is presented. Data on morphometric analysis and plastic features of the identified L. nasus are provided. The porbeagle shark (1 ind.) was caught during the target fishing of the Patagonian toothfish Dissostichus eleginoides in April 2009. The detected coloration peculiarities make it obvious that the so called «black-faced» specimens of Lamna nasus occur in the southern areas of all the oceans and evidence their circumglobal distribution in the Southern Hemisphere.

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.
