Abstract

fetched live from OpenAlex

Four commonly held beliefs about litter decomposition rates were tested in a suite of field experiments in British Columbia forests: (1) decomposition is slower in cold (northern and high-elevation) forests, (2) decomposition is faster in clearcuts than in forests, (3) broadleaf litter decomposes faster than needle litter, and (4) decomposition is faster in N-fertilized forests. Litter decomposition was slowest in dry biogeoclimatic zones and fastest in wet zones. Overall, it appears that moisture is more limiting than temperature for litter decomposition across British Columbia. The effect of clearcutting on litter decomposition rates varied among forest types. Province-wide, mass loss of pine needle litter was significantly slower in clearcuts than in adjacent forests, but this difference disappeared after 3 years. Aspen leaves and forest floor material decomposed at similar rates in forests and clearcuts. Decomposition of broadleaf litter was slightly faster than needle litter during the first 2 years, but slowed in subsequent years. After 3 years there was no significant difference between the mass remaining for broadleaf and conifer litter. In N-fertilized plots, higher N concentrations did not affect the rate of decay in litter or in forest floors. Many of our beliefs about litter decomposition and influences of forestry practices thereon should be revised in light of new empirical evidence.

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.
