TABLE 2.

Phenotypic selection with relative fitness calculated over all bees (N = 153) using either the regression model with log transformed relative fitness or bootstrapping to determine the statistical significance of the selection coefficients.

Statistical Method		Log transformed		Bootstrap
Trait	Selection coefficient	Estimate	P	Estimate	Lower 95%	Upper 95%

The methodology followed to obtain the different selection coefficients is summarized in Table 1. The letter P stands for probability and NS for not statistically significant. Flr stands for open flowers per raceme and Chr for flower chroma.
