Impact of climate on juvenile mortality and <i>Armillaria</i> root disease in lodgepole pine
Bibliographic record
Abstract
Variable and sometimes high levels of mortality in lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) planted in western Alberta have raised awareness of the need to forecast and ameliorate risks to reforestation success. Mortality and health of regeneration during the 12 years following harvest were monitored and evaluated in relation to climate, site and silvicultural treatments. Results suggest that physiological stress related to evapotranspiration is the most prevalent cause of overall juvenile mortality and susceptibility to Armillaria root disease in planted pine. Mortality and disease not only increase at higher rates of drying during the growing season, but an opposite effect is also demonstrated whereby they decrease with increasing spring temperatures. Mechanical site preparation aimed at countering mortality and disease of planted stock with improved soil conditions appears to have good potential for ameliorating adverse climatic effects in juvenile stands.

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.
