Effects of light intensity on adaxial surface area A and FA B in A. Alliariae leaves. Each point represents the most basal leaf of a plant growing in a shaded (filled circles) or open (open circles) site. The solid line indicates a significant relationship (p < 0.0001) and the dashed line indicates a marginally significant relationship (p = 0.0732). Lines of best fit are back-transformed from models fitted to Box-Cox transformed data.
