Abstract

fetched live from OpenAlex

A 'Turdus migratorius' (American Robin) nest was found in southern New Brunswick, Canada, containing 52 mature sporocarps ('truffles') of 'Elaphomyces granulatus' (false truffle), a species of hypogeous fungus common across North America. Teeth marks on the truffles indicated they had been cached in the nest by a 'Tamiasciurus hudsonicus' (red squirrel). The truffles appeared to have been air-dried before caching and were well preserved. Mean (± SD) weight of each truffle was 3.3 ± 1.4 g, with a total weight of cached material of 173 g. Although caching of epigeous fungus by squirrels is well documented in the literature, records of cached hypogeous fungi are relatively uncommon, and caches involving disused bird nests appear to be rarely encountered.

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.
