Whole-tree water relations of western gall rust infected lodgepole pine trees
Bibliographic record
Abstract
Lodgepole pine (Pinus contorta Dougl. ex Loud.) trees having galls resulting from infection by western gall rust (WGR; Endocronartium harknessii (J.P. Moore) Y. Hiratsuka) have a lower ability to conduct water than nongalled stems. Experiments were conducted to compare the leaf-specific hydraulic capacity (Q L; g H2O·cm−1 ·MPa−1) of galled and control trees. Specific objectives were to test the hypothesis that Q L was reduced in galled trees, to determine which components of Q L, if any, varied between galled and control trees, and to test the hypothesis that water stress would more negatively affect galled trees than control trees. Under well-watered conditions, galled trees had lower Q L than control trees. This difference was associated with an increased water potential difference between the soil and leaves (ΔΨ MPa) rather than a change in transpiration per unit leaf area (E L; g H2O·cm−2 A L). Although water stress reduced Q L, the effect was similar for galled and control trees, indicating that the former were no more vulnerable to xylem cavitation than the latter. The similarities in the short-term responses of galled and control trees under well-watered conditions are consistent with the observation that stem galls do not result in rapid tree mortality.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
