Susceptibility of pine plantations to attack by the pine shoot beetle (Tomicus Piniperda L.) in southern Ontario
Bibliographic record
Abstract
Tomicus piniperda (L.) (Coleoptera: Scolytidae), was discovered in Ohio in 1992 and spread throughout southern Ontario, Quebec, and the United States. The objectives of this study were to (i) determine the relationships between tree and site characteristics and the number of stem and shoot attacks by T. piniperda in southern Ontario; and (ii) determine if T. piniperda is an aggressive beetle in southern Ontario. Forty-three sites of varying pine species compositions were surveyed across southern Ontario. An abundance of dead and low-vigour pine trees increased susceptibility of sites to attacks by T. piniperda . Significant negative relationships were detected between the number of attacks and the mean height, age, dbh, basal area, canopy cover, duff depth, and radial growth increments of the sites. Pure red pine sites had significantly fewer attacks than sites of pure scots pine and mixed jack pine, which was attributed to differences in tree vigour, and management.

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.
