The effect of Eurosta solidaginis parasitism on pollinator preference in Solidago canadensis
Bibliographic record
Abstract
Solidago canadensis is a self-incompatible perennial species indigenous to North America that reproduces asexually via rhizomes and sexually via seeds. It is the favoured host of the gall fly, Eurosta solidaginis. Sexual reproduction leads to faster rates of adaptation in stressful environments and may be advantageous in the maintenance of host-parasite coevolution. The effect of infection by the gall fly on pollinator visitations at the patch and at the ramet level was assessed as a proxy for the ability to sexually reproduce. The study was conducted by analyzing pollinator preference at both the patch level and individual ramet level through successive observations of pollinator visitations. Though the variation in the number of pollinator visitations could be accounted for by time of day and median bloom stage, the percentage of infected ramets in a patch was not a significant explanatory variable. This suggests that gall formation does not affect pollinator preference and that the capacity to sexually reproduce is likely not reduced because of the host-parasite interaction. Broadly, this study served as an example of how pollinator preference may be utilized as a measure of fitness, and to further understand how selective pressures affect plant populations that reproduce both sexually and asexually.

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.
