TABLE 5.

Phenotypic selection for leafcutting bee with relative fitness calculated using either the proportion of flowers visited or the proportion of flowers tripped by leafcutting bees.

The statistical significance of the selection coefficients was only determined using bootstrapping due to the high number of plants with no leafcutting bee visits. The methodology used to obtain the different selection coefficients is summarized in Table 1. The abbreviation NS stands for not statistically significant. Rcps stands for racemes per stem and hue for flower hue.
