Concentrations of chlorophyll as a function of flow speed in 1992. Other interpretations as in Figure 2. There was no significant best-fit regression. nonsignificant, monotonic decline in growth rate as speed increased (for all b: minimum P = , maximum r = ). Growth rates of Pseudochitinopoma individuals de- clined monotonically and significantly with flow speed (Fig. 6;b= , P = , r = ). 1992 experiment The concentration of chlorophyll in pipes did not de- pend on flow speed (Fig. 7). The monotonic regression was not significant (for all b: minimum P = , maxi- mum r = ), nor was the polynomial regression. Therefore, the horizontal flux of chlorophyll varied by a factor of only about 5 over the 5 X range of flow speeds. Growth rates of Semibalanus cariosus did not depend on flow speed (Fig. 8). The monotonic regression was not significant (for all b: minimum P = , maximum r = ), nor was the polynomial regression. Growth rates of Pollicipes polymerus also did not de- pend on flow speed (Fig. 9). The monotonic regression was not significant (for all b: minimum P = , maxi- mum r = ), nor was the polynomial regression. Growth rates of Balanus crenatus appeared to be min- imal at the two lowest flow speeds, to increase sharply to a maximum growth rate at U = 8 cm s~', and to decline Pseudochitinopoma occidentalis Semibalanus cariosus
