Wildlife EcologySYSTEMATICS OF NORTHEASTERN MEADOW VOLE (MICROTUS PENNSYLVANICUS) SUBSPECIES, WITH EMPHASIS ON THE
Bibliographic record
Abstract
The Penobscot meadow vole (Microtus pennsylvanicus shattucki) (PMV) is an insular subspecies of meadow vole (M. pennsylvanicus) inhabiting the islands of North Haven, Islesboro, and Tumbledown Dick in Penobscot Bay, Maine. It is one in a suite of island meadow vole subspecies which has been described from southern New England through eastern Canada. The subspecific recognition of M. p. shattucki, along with the others in this group, was solely based on a univariate analysis of a few morphological characters, which has fostered debate about the validity of the subspecies. Despite this uncertainty, the taxonomy is widely applied and conservation issues have been raised: M. p. shattucki was listed as a Species of Special Concern in the state of Maine when that listing was in use. The U.S. Fish and Wildlife Service did not propose M. p. shattucki for listing at the federal level because of lack of information on the subspecies. Concern about losing unique island taxa such as the PMV is warranted because another subspecies in this group, M. p. nesophilus, which was found on Gull Island, NY has already gone extinct. To clarifjl the taxonomic status of A4. p. shatrucki for conservation purposes, I used multivariate discriminant function analysis @FA) to examine historical and recent

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.
