Incidence of slime flux in deciduous trees of Southern Ontario
Bibliographic record
Abstract
Wetwood is caused by the bacterial infection of the heartwood of deciduous trees which creates a build-up of pressure within the tree and causes fluid to be exuded. The phenomenon of wetwood exudates forming streaks down the bark is known as slime flux. While wetwood is a well-studied subject because of its potential negative impacts on lumber quality, there is a paucity of research on the biology, ecology and distribution of slime flux. The research conducted here in Ontario, Canada used a visual survey to estimate the occurrence of slime flux in deciduous tree species. Local forests and parks in Southern Ontario were surveyed systematically in transects, targeting 100 trees per transect. If slime flux was observed, then source of the flux was also recorded. Among over 1700 trees inspected, 44 had visible signs of slime flux. Analyses showed that slime flux incidence was positively correlated with tree age, and that incidence differed among tree species, with greater incidence in parks than in forests. Slime flux occurred mainly from bark cracks at the bottom four meters of the tree base.

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.
