Abstract

fetched live from OpenAlex

Parasphaeria boleiriana is a new example of a xylophagous and subsocial cockroach with intestinal flagellates, which was observed in remnants of the Brazilian semideciduous Atlantic forest. Parasphaeria boleiriana formed galleries by burrowing into the rotten trunks of softwood trees in the forest understory. Females stayed in chambers in the wood with their neonate nymphs for 12.4 ± 6.2 days (mean ± SD), but trophallaxis was not yet observed. According to multiseasonal sampling, nymphal development took longer than 1 year, but adults appeared to be short-lived. Nymphs did not disperse within the trunk during their development but remained relatively aggregated. Parasphaeria boleiriana fed on wood, and their digestive tract harboured five species of flagellates belonging to the order Trichomonadida. All these characteristics contrast with those of other known wood-feeding cockroaches, especially the low adult longevity and short period of brood care, associated with a high prevalence of intestinal flagellates.

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. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
