At days 49 and 194 the Lithothamnium and Waernia treatments were different from the rest (SNK test). All other combinations of treatments at each time were indistinguishable (statistical analysis from Sokal and Rohlf 1969). Abbreviations as follows: LITH = Lithothamnium. light, WAER = Waernia.

Data on numbers of live planulae were not taken regularly during 1981. During the 1982 experiments, live planulae were again counted every other day. In this set of experiments mean survivorship was between 11 and 39 percent for 30 days for larvae that never did metamorphose (Fig. 7). 28 percent of the light control group, and 61 percent of the 100. 10 20 DAYS 10 20 DAYS 30 FIGURE 7.
