Abstract

fetched live from OpenAlex

The objective of this study was to explore the effects of wind-caused sway on the growth and stem hydraulic properties of fire-origin juvenile lodgepole pine (Pinus contorta Dougl. ex Loud.) stands after thinning. Nine plots were thinned and trees were treated to suppress or exacerbate sway from the wind: thinned and supported with a pole (TP), thinned with an added sail (TS), thinned control (TC), and unthinned control (UC). Terminal leader growth, radial increment, and earlywood and latewood widths at breast height were measured for the last six growing seasons. The specific hydraulic conductivity of stems was measured. The results showed that thinning increased diameter growth and reduced height growth and slenderness coefficient (particularly for trees with added sails) compared with the unthinned control. Trees from thinned stands had reduced specific conductivity compared with the trees from unthinned controls, suggesting that tree bending caused functional damage to sapwood. Specific conductivity was 1.36 × 10 –5 , 1.06 × 10 –5 , 0.96 × 10 –5 , and 0.83 × 10 –5 m·s –1 in UC, TP, TC, and TS treatments, respectively. Trees from thinned stands, however, increased their total leaf area in the years following thinning.

Teacher imitation

Not 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.
