Compensatory growth of <i>Euphorbia peplus</i> regenerating from a bud bank
Bibliographic record
Abstract
Tolerance to very severe disturbance by the annual herb Euphorbia peplus L. was examined. We explored the role of disturbance timing, competition, and site productivity on the performance of disturbed plants. Ninety-three percent of disturbed plants survived following disturbance 14 d after plant emergence, whereas only 48% of disturbed plants survived disturbance 42 d after emergence. Early disturbed plants compensated for biomass loss and had higher fecundity than undisturbed plants, but this was not the case for plants that were disturbed at later times following emergence. Field assessment revealed that disturbed plants were, in general, of the same height as undisturbed plants, even under competition. Undisturbed plants had very conservative architecture across various conditions (competition and nutrients), whereas disturbed plants had more branched architecture under moderate competition and nutrient availability. Accordingly, we suggest that E. peplus utilizes a bet-hedging strategy where adventitious meristems are reserved for regrowth after a severe disturbance event that removes all dormant axillary meristems. Moreover, we propose that the tolerance to disturbance in short-lived species could play an important role in the ecology of disturbed communities. Finally, the tolerance to disturbance could be one of the prerequisites of invasibility of E. peplus in non-native ranges. We also speculate about the potential costs and benefits related with the tolerance to disturbance in short-lived species and about a mechanical control of E. peplus in invaded ranges.

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.
