13 Spending Time in the Forest Responses of Cavity-Nesters to Temporal Changes in Forest Health in Interior British Columbia
Bibliographic record
Abstract
An ongoing major outbreak of mountain pine beetle (Dendroctonus ponderosae) and other bark beetles and forest insects in British Columbia has resulted in large-scale increases in the availability of dead and dying trees. Using point count data from a long-term study on cavity-nesting birds and mammals, we describe how individual populations of cavity-nesting species, and the cavity- nesting community as a whole, have responded to the outbreak. We fit a linear trend model to 100 species observed during point counts, 21 of which showed a significant decline in abundance over the study period, 21 showed an increase in abundance, and 58 showed no trend. These concurrent declines and increases in abundance mean that community-level measures (species richness and abundance within cavity-nesting guild) have not changed following the outbreak, indicating the community structure has remained stable during the large increase in resource availability. These results suggest that species' responses to the availability of resources may thus also depend on the current status of competitors, predators and facilitators.

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.
