Figure 6


Fig. 6. Drag coefficient versus structural properties. (A,B) Low velocity (0.5 m s–1). (C,D) High velocity (3.0 m s–1). Linear regressions of CD to log-transformed structural flexibility (slope=–0.093, R2=0.47, P=0.03) and CD to modulus (slope=0.026, R2=0.50, P=0.02) were significant at low velocity. Neither relationship was significant at high velocity (P>0.05). Species labeled as per Fig. 4.
