Diversity of saproxylic Cecidomyiidae (Diptera) in a Quebec hardwood forest
Bibliographic record
Abstract
The diversity of saproxylic Cecidomyiidae (Diptera) associated with decaying logs was studied in an old-growth forest on Mont Saint-Hilaire, Quebec from June until September 2004. More than 24 000 specimens representing 323 species and morphospecies were collected in emergence traps set over American beech or sugar maple logs in two different stages of decay. The paedogenic species Miastor metraloas Meinert was by far the most numerous species with 17 002 individuals and was excluded from further analyses. Most of the remaining species were fungivores, detritivores or predators. Significantly more specimens were collected in logs in the more advanced decay stage, and indicator species analysis showed that the most abundant species were associated with this decay stage. Overall species richness was not significantly different between decay stages or tree species; however, non-metric multidimensional scaling indicated that the species assemblages associated with decay stage and tree species were significantly different despite the similar species richness.

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.
