Homalotheciella subcapillata (Hedw.) Broth., a new moss species to Canada from old broadleaved forests of Nova Scotia
Bibliographic record
Abstract
We report Homalotheciella subcapillata (Hedw.) Broth. for the first time in Nova Scotia, found in the western-most part of the province. Upon examination of a previously reported collection of this species from Saskatchewan, we determined that the previous collection was misidentified and conclude that our collections represent the first records of this species for Canada. The moss was found to grow only on old beech (Fagus grandifolia Ehrh.) trees in mature to old growth mixed broadleaved forests. The species has likely been present in Nova Scotia for many decades but was not previously detected due to low search effort. Given the apparent rarity and substrate specificity, the decline of its host tree, and the fact that it is threatened or vulnerable in the USA, we recommend that steps be taken to conserve this species and its habitats in Nova Scotia. Keywords: arboreal, Brachytheciaceae, bryophyte, epiphyte, moss
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.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
