Abstract
Erethizon dorsata (Linnaeus 1758) Hystrix dorsata Linnaeus 1758, Syst. Nat., 10th ed., Vol. 1: 57. Type Locality: E Canada (= Quebec Prov.). Vernacular Names: North American Porcupine. Subspecies:: Subspecies Erethizon dorsata subsp. dorsata Linnaeus 1758 Subspecies Erethizon dorsata subsp. bruneri Swenk 1916 Subspecies Erethizon dorsata subsp. couesi Mearns 1897 Subspecies Erethizon dorsata subsp. epixanthus Brandt 1835 Subspecies Erethizon dorsata subsp. myops Merriam 1900 Subspecies Erethizon dorsata subsp. nigrescens Allen 1903 Subspecies Erethizon dorsata subsp. picinum Bangs 1900 Distribution: C Alaska (USA) to S Hudson Bay and Labrador (Canada), south to E Tennessee, C Iowa, and C Texas (USA), N Coahuila, Chihuahua, and Sonora (Mexico), and S California (USA). Conservation: IUCN – Lower Risk (lc). Common. Discussion: Reviewed by Miller and Kellogg (1955:631), who restricted the type locality; also see Anderson and Rand (1943). Includes couesi (see review by Woods, 1973). Karyotype has 2n=42 and FN=78 (George and Weir, 1974).
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.
