Pine needle rust effect on <i>Pinus banskiana</i> in response to interspecific plant competition and telial host density
Bibliographic record
Abstract
Three compartments differing in soil texture were established in 1994 to examine interspecific competition using Pinus banskiana Lamb. and 11 competitive species including Aster macrophyllus L. Each competitive species was established in six planting densities in combination with P. banksiana. Since P. banksiana and A. macrophyllus are hosts of the pine needle rust (PNR) fungus, Coleosporium asterum (Diet.) Syd., conditions were inadvertently created for examining the effect of PNR on tree growth under interspecific competition. Tree size was measured in 1995 and 1996. PNR was assessed in 1996 (incidence) and 1997 (severity). Pinus banksiana root collar diameter, stem length, and crown diameter were significantly lower in the loam soil texture compartment compared with the clay or sand compartments. Using the same metrics, P. banksiana size was reduced as competitor density increased in 1995 and 1996, particularly for A. macrophyllus. Further, P. banksiana size was significantly reduced by PNR infection in 1996. Excluding the plots with A. macrophyllus, P. banksiana infected in 1996 were significantly larger than disease-free trees in the clay and sand compartments, suggesting that larger trees may represent larger targets for spore deposition. In 1996, PNR incidence was significantly correlated with proximity to A. macrophyllus plots.

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.
