Fig. 4. Ucrit,a and Ucrit,C versus the structural flexibility and modulus. (A) Ucrit,a versus structural flexibility. (B) Ucrit,a versus modulus. (C) Ucrit,C versus structural flexibility. (D) Ucrit,C versus modulus. No linear regressions were significant (P>0.05). Species labeled as: Grateloupia ({blacksquare}), Laminaria (•), Petalonia ({diamondsuit}), Agardhiella (Figure 4), Scytosiphon (Figure 4), Codium (Figure 4), Chondrus (Figure 4), F. distichus (Figure 4), F. vesiculosus (Figure 4) and Mastocarpus (Figure 4).
