Abstract
Coarse woody debris (CWD) in boreal ecosystems has been hypothesized to play an important nutritional role following stand-replacing disturbances such as fire or harvest. Sites with shallow soil over bedrock or those with coarse textured soils can be especially susceptible to overstory removal as low carbon and nutrient pools may limit stand productivity in subsequent rotations. \nThis dissertation includes results from a series of in-situ and ex-situ experiments examining the nutritional role of CWD. The ex-situ experiment was designed to evaluate whether species (aspen, spruce), origin (fire, harvest), and/or decay class (1-5) influence the timing, and rate of nutrient release from CWD. Source/sink relationships of CWD leachate were largely a function of CWD decay stage for C (source, peaking at decay class 4 and then a slight decline in decay class 5), N (initial sink to eventual source) and P (initially a large source followed by low rate of release). Leachate values from harvested logs were similar to those of fire origin, with the exception of N and Mn, suggesting considerable volatilization of these two nutrients during wildfire events.

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 it
