Selection coefficients arising from the effects of nine separate mutations on competitive male mating success when males are raised in their ancestral (cornmeal-based) or a novel and more stressful (corn-flour-based) larval food environment (r=0.903, P<0.001). The error bars represent 95% confidence intervals from 1000 bootstrap replicates. A 1:1 line is shown for reference.
