Bromeliad‐associated Reductions in Host Herbivory: Do Epiphytic Bromeliads Act as Commensalists or Mutualists?
Bibliographic record
Abstract
Abstract Many members of the family B romeliacae are able to adopt epiphytic lifestyles and colonize trees throughout the N eotropics. B romeliacae do not extract nutrients from their hosts and confer relatively minor costs on their host plants. We suggest that bromeliads, however, may benefit their hosts by providing habitat for predators of host plant herbivores. We report a correlation between bromeliad presence and a reduction in herbivore damage in orange trees, an effect that is increased when bromeliads are colonized by ants. Our results may have important implications for agricultural systems in the N eotropics, where bromeliads are often removed in the belief they are parasitic. We instead demonstrate that bromeliads may impart a benefit to their hosts, and speculate that under particular circumstances they may be part of a three‐species mutualism.

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.
