Belowground starch consumption after recurrent severe disturbance in three resprouter species of the genus<i>Erica</i>
Bibliographic record
Abstract
It is generally assumed that belowground starch reserves are consumed partially and gradually after successive resprouting events in resprouter woody plants. We have explored the aboveground (biomass) and belowground (root starch) response of three species of Erica, Erica australis L., Erica scoparia L., and Erica arborea L., after different histories of disturbance intensity to test the existence of a gradual decrease in (i) the final biomass of the aboveground regrowth and (ii) the relative amount of root starch across increasing levels of disturbance frequency. Increasing clipping frequency produced a progressive reduction in the final regrowth in the three species. By contrast, root starch levels dropped markedly in plants of all clipping treatments when compared with root starch of unclipped plants, but significant differences were not detected among clipping frequencies. This pattern was consistent across the three species of Erica. This study highlights a crucial role of belowground (root) starch reserves for postdisturbance regrowth in resprouter species of Erica. It also shows a consistent pattern of rapid, not conservative, consumption of starch reserves after the complete removal of the aboveground part, nearly irrespective of the previous history of disturbance frequency.

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.
