Aclimatación morfológica a la luz en seis especies arbóreas de los bosques montanos de Costa Rica
Bibliographic record
Abstract
The acclimatization to two light regimes of the leaves of six species of trees from Costa Rican montane forest was investigated. Seedlings and saplings of the selected species were chosen from prior to the expansion of the foliar lamina to complete development. Groups of specimens previously growing on light were subjected to shade, whilst plants previously shaded were exposed to light. Other did not undergo a change of light regime and were used as "light controls" and "shade controls". The morphological characteristics evaluated were: foliar area, lamina thickness, stomatal density, specific density, specific leaf weight and specific leaf water contento The observed responses suggest that Quercus copeyensis and Drimys winteri have a greater responses potential for acclimatization to shade whilst Schefflera rodriguesiana acclimatizes hetter to brighter conditions. Vaccinium consanguineum, Weinmannia pinnata and Quercus costaricensis have the ability to acclimatize to both regimes.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
