Differences in herbivore damage to <i>Arctium minus</i> in open and forest habitats in its non-native range
Bibliographic record
Abstract
Exotic plants do not always escape enemies in new areas; instead, they may be damaged by co-invading non-native enemies or by enemies recruited from native species. However, even when such enemies exist in an invader’s new range, escape may still be possible if particular habitats offer low-damage refuges. In this study, herbivory on the non-native common burdock (Arctium minus (Hill) Bernh.) were compared between open and understory habitats, with high and low sunlight exposure respectively, on five sites in Ontario, Canada. Open-habitat populations showed relatively reduced herbivore damage; this may be due to herbivores occurring less abundantly in open habitats or burdock expressing greater defences in open sites. These results emphasize that enemy release is not an absolute effect, but can depend on an individual’s habitat. As well, they suggest herbivory potentially may help to confine burdock primarily to open habitats.

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.
