Abstract
Snowmelt is considered to affect growth of the boreal forest.So, we tested the hypothesis that late snowmelts delay the onset of xylogenesis and reduce xylem production in trees.Timings of xylem formation were compared to the dates of complete snowmelt combining a 7-year monitoring of cambial activity with meteorological records in four plots of Picea mariana in Quebec, Canada.The spatial and temporal variability in snowfall was analyzed separately, so taking into account both the long-and short-term effects.Snowfall occurred from October to May, with a snow cover lasting 173-199 days.Overall, xylogenesis lasted 99-117 days, with onsets ranging from late May to mid-June.The highest cell productions were observed in the warmest site, where the longest periods of growth were observed.Although at long-term the effects of snowmelt were significant for both onset and duration of xylogenesis and cell production, at short-term only the relationship between the onset of xylogenesis and the date of complete snowmelt was significant.The initial hypothesis could be confirmed only partially.The different responses to the long-and short-term analyses demonstrate the multi-scale influence of snowfall on tree growth and the determinant role of nutrient cycling in the productivity of boreal ecosystems.

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 it
