Abstract

fetched live from OpenAlex

We collected Nyctiphanes simplex in Barkley Sound, Canada (48°54′N, 125°6′W) between May and September 1998. This was during the most intensive ENSO (El Niño Southern Oscillation) event recorded and when southward current velocities were anomalously low. This is a range extension of about 330 km NNW of where N. simplex was collected previously by plankton sampling gear and about 65 km NNW of where it was found in fish stomachs. Animals ranged between 10 and 20 mm total length and were at various states of maturity. We present length-frequency and maturity stage distributions as well as length-mass relationships. Results from an ongoing herring diet monitoring programme showed that they did not feed on N. simplex.

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.
