Abstract
151. Creeping Vole Microtus oregoni French: Campagnol de I'Oregon / German: Oregon-Wihimaus / Spanish: Topillo de Oregén Other common names: Oregon Meadow Mouse, Oregon Vole Taxonomy. Arvicola oregoni Bachman, 1839, Astoria, Clatsop County, Oregon, USA. Four subspecies are recognized. Subspecies and Distribution. M.o.oregon:Bachman,1839—WWashington,WOregon,andNWCalifornia,USA. M.o.adocetusMerriam,1908—extremeSCOregonandNCCalifornia,USA. M.o.bairdiMerriam,1897—SCOregonandextremeNCCalifornia,USA. M. o. serpens Merriam, 1897 — SW British Columbia, Canada. Descriptive notes. Head-body 97-112 mm, tail 32-42 mm, ear 9-10 mm, hindfoot 19-19 mm; weight averages 19 g. The Creeping Vole is one of the smallest species of Microtusin North America and has a very shorttail. Pelage is dense, soft, and sooty gray to yellowish brown on back; venter is dusky. Tail is indistinctly bicolored, and ears are small, blackish and lightly haired. Hindfeet have five plantar tubercles. Molars are small, M? has 2-3 closed triangles, M, has five closed triangles, and M, has three transverse loops. Habitat. Dry short-grass habitats in coniferous forests. Clearcut disturbed sites and areas where timber slash has been burned support higher densities of Creeping Voles because of the herbaceous-dominated vegetation. Food and Feeding. Diets of Creeping Voles primarily include herbaceous vegetation (forbs and grass) and fungi. Captive individuals have survived on bluegrass, clover, and apples. Breeding. Breeding of Creeping Volesis reportedly year-round but mostly in March— September. Gestation is ¢.23 days, and 4-5 litters with 3-4 young each are produced annually. Young are born in nests of dry grass placed in cavities under logs or in similarly protected sites. Activity patterns. Creeping Voles are terrestrial. Movements, Home range and Social organization. It is unknown if Creeping Voles undergo large multiannual population fluctuations, as often recorded for other species of Microtus. They are known to tunnel but not exclusively, and they often use aboveground runways. Home ranges are 0-05-0-38 ha for males and 0-04—0-23 ha for females; they decrease in size through summer. Densities have been reported as high as 138 ind/ha at the northern edge of the distribution in British Columbia, but much lower in the south. Status and Conservation. Classified as Least Concern on The IUCN Red List. Bibliography. Bradley, Ammerman et al.

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.
