Bibliographic record
Abstract
The grizzled skipper butterfly is an Appalachian Mountain habitat specialist that requires shale barren habitats with abundant exposed crumbly rock or soil. Shale barrens are semi-open shale slopes with sparse herbaceous vegetation and tend to be surrounded by scrubby oak or oak-hickory woodlands, often with a component of Virginia pine (Pinus virginiana). These dry, shale slopes should favor plentiful growth of the larval host plant, Canada cinquefoil (Potentilla canadensis) and tufted grasses like broom-sedge (Andropogon virginicus). Occupied sites also support a variety of spring plants such as spring beauty (Claytonia spp.), phlox (Phlox subulata), and birdsfoot violet (Viola pedata) which provide nectar food for adults. The caterpillars feed on Canada cinquefoil, which is a very common species that can be found growing in lawns. However, the grizzled skipper is restricted to a narrow range of very hot rock outcrop habitats with the host plant. Grassy roads, right-of-ways, and other disturbed areas on south- or west-facing slopes over shale substrates can be suitable habitat if they maintain the appropriate plant community structure with Canada cinquefoil as a primary component. Occupied sites are always in close proximity (within 30 m) of densely wooded areas. Adults seldom occur more than about 30 m from forested areas even if host plants occur in open canopy areas adjacent to the forest edge. Another key site characteristic is the presence of a source of moisture, such as temporary or permanent streamlets, or even muddy puddles in deep wheel ruts. Perhaps for this reason, the grizzled skipper is not typically found on ridges, but more often occurs along the bases of slopes.
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.
