Forest Habitat Characteristics Associated with Simplocaria metallica (Sturm) and Other Pill Beetle Species (Coleoptera: Byrrhidae) in Northern Alberta, Canada
Bibliographic record
Abstract
Despite close and potentially interesting associations between pill beetles (Coleoptera: Byrrhidae) and bryophytes on which they are obligate feeders, little is known about byrrhid ecology in Canadian forests. To determine the extent to which boreal forest stands support populations of pill beetles, we established a systematic sampling grid of 200 sampling sites covering 82 km2 of boreal mixedwood forest in northwestern Alberta. We found that byrrhid species, especially Simplocaria metallica (Sturm), occur in association with stands of small black spruce (Picea mariana (Mill.) BSP; Pinaceae) subject to frequent disturbances. The habitat occupied by black spruce in this part of the boreal forest also includes potential bryophyte hosts of several pill beetle species. Our findings suggest that pill beetles can be used as indicators of disturbances such as fire, harvest, gravel pit construction, and road ditching. They seem to flourish in frequently disturbed forested habitats such as peat bogs and taiga forest that provide arid environmental conditions similar to arctic or alpine environments.

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.
