Fig. 8. Values of F_e/F are plotted against extension for Araneus and Nephila MA silk. No swelling correction was applied to Nephila MA silk and so the F_h/F values (Fig. 5) are equivalent to F_e/F. Nephila MA silk values are represented by black squares and are fitted to the linear regression, y=0.13x+0.51; N=7; R²=0.77; P<0.01. Araneus MA silk measurements are represented by black circles; open circles are F_e/F values taken from Gosline et al. (Gosline et al., 1984). The Araneus MA F_e/F data are fitted to the linear regression, y=0.02x–0.15; N=10; R²=0.68; P<0.01.
