Crab spiders show mixed effects on flower-visiting bees and no effect on plant fitness components

Abstract
:Predation on flower-visiting insects can potentially reduce pollination levels and hence plant fitness. We tested this prediction in a field experiment with 10 matched pairs of milkweed patches in which one patch in each pair contained crab spiders and the other patch was predator free. Significantly fewer honeybees were observed in the spider than no spider patches, but there was no spider effect on the two species of bumblebees. A possible explanation for this difference is that the honeybees suffered three times higher predation rates than the bumblebees. There were no spider effects on either the rate of pollinia removal from milkweed flowers or the number and mass of seeds produced. The results suggest that crab spiders may have only small effects on bees and plant fitness, at least where bees are abundant.

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 it
