Fig. 5. Values of Fh/F are plotted against
extension for Araneus and Nephila MA silk. Nephila
MA 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. Measurements on
Araneus MA silk are represented by black circles; open circles are
Fh/F values taken from Gosline et al.
(Gosline et al., 1984). The
Araneus MA Fh/F data are fitted to the
linear regression, y=0.02x–0.53; N=10;
R2=0.68; P<0.01.
