Transplantation of<i>Larix principis-rupprechtii</i>Mayr. and<i>Picea meyeri</i>Rehd. seedlings to low altitude and two contrasting light environments reveals climate warming effects on early seedling performance
Bibliographic record
Abstract
By using altitude as a surrogate of warming treatment, we transplanted seedlings of Larix principis-rupprechtii Mayr. and Picea meyeri Rehd. Et Wils. from their original altitude (2000 m a.s.l.) to a lower altitude (1500 m a.s.l.) and grown in two light environments (full and low) at both altitudes for two years in north-central China, to determine the effects of warming and light on seedling survival and growth performance. The results showed that altitude and light did not affect survival rates of both species, but had significant interactions on their growth performance. Although both species had greater heights, root collar diameters and biomass accumulations in full than in low light at high altitude, such growth advantage disappeared or even reversed at low altitude, especially for L. principis-rupprechtii. Moreover, L. principis-rupprechtii seedlings increased specific leaf area, leaf area ratio and shoot:root ratio at low altitude. Despite this study is relatively short termed, such results demonstrated the importance of shade tolerance in species responses to warming and may imply an altered regeneration pattern of L. principis-rupprechtii if the current warming trend remains in the future.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
