Abstract
American marten (Martes americana) are typically associated with mature coniferous forests. Some recent results, however, suggest that marten habitat selection may also operate at a finer scale. We therefore described site characteristics of 24 martens that were radio-tracked and snow-tracked between August 2002 and March 2004. From these data we developed 2 resource selection functions, one for summer and the other for winter, using logistic regressions. In summer, selected sites were mainly characterized by abundant biomass of spruces and short (≤30 cm) herbaceous plants and low biomass of tall (>30 cm) herbaceous plants. Other factors, such as increased coniferous canopy closure and amount of coarse woody debris (CWD) and reduced lateral cover (LC5) were included in the composite model. In winter, sites with closed coniferous canopy and LC5, high snow sinking depth, greater amounts of CWD, greater basal area, and greater tree density were more likely to be visited by marten. These variables may be related to 3 factors that play roles in marten ecology: prey abundance, protective cover, and thermoregulation. Our results also show that, unlike clear-cutting with protection of regeneration and soils (CPRS) and pre-commercial thinning (PCT), partial logging techniques (PL) could maintain, under certain conditions, the structural elements required by pine marten in a managed forest. These elements would favour prey abundance and detection, protective cover, and rest and thermoregulation sites.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
