Abstract

fetched live from OpenAlex

Vine maple (Acer circinatum PURSH) is a common understory species in the temperate rainforests of southwest British Columbia. The influence of surficial geology, light availability, ground water levels, aspects of the microtopography and of vine maple persistence, priority effects and layering on the distribution pattern of vine maple within oldgrowth stands was investigated in this study. The distribution pattern was primarily influenced by surficial geology. High vine maple cover was significantly connected to rockfall sediment. This was probably a relic of vine maple dominance during primary succession. On a smaller scale light availability and potentially former light availability influenced vine maple cover and occurrence. Ground water levels, soil properties and slope inclination had no influence on vine maple distribution. Vine maple was able to delay but not completely repress gap closure in gaps it occupied.

Full frame distilled prediction

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.
