Abstract
Bark beetle-vectored phytopathogenic fungi can play critical roles in how beetle outbreaks affect the health of forest trees. However, trees can defend themselves against fungal infection. How Grosmannia abietina , a symbiotic fungus of spruce beetle ( Dendroctonus rufipennis ), affects the health of mature hybrid white spruce ( Picea engelmannii x glauca ) and is in turn affected by the tree's defenses are unknown. We conducted field inoculations of this spruce to study the degree of pathogenicity of G. abietina , characterized the trees' resulting defensive monoterpene responses, and assessed monoterpene effects on fungal growth and reproduction in laboratory bioassays. Our results indicated that G. abietina is phytopathogenic to hybrid white spruce, which induced monoterpenes in response to infection. Dominant induced monoterpenes generally inhibited fungal growth but stimulated spore production. These findings provide insights into the bidirectional effects between spruce beetle-vectored fungi and host trees, highlighting the complex role of monoterpenes in modulating fungal activities.

Full frame distilled prediction
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
