In the present study, the effect of grazing refuges was clearly visible on some specimens of the fruticose Mesophyllum printzianum, where pockets of diatoms proliferated in the narrow gaps between protruberances or the sunken pore plates of conceptacles (Fig.

Settlement of abalone (Haliotis iris) larvae in response to five species of coralline algae

The number of conceptacles per crust, either intact or eroded, was not significantly different among treatments (ANOVA, intact: [F.sub.2] = 0.29, P = 0.74; eroded: [F.sub.2] = 0.15, P = 0.86, Fig 6A, Table 4).

We did not count the number of spores within the conceptacles; however, the presence of healthy, reproductive structures suggests that the alga is able to produce spores with potential to settle and recruit onto the experimental panels, as suggested for a number of macroalgal species (Santelices, 1990).
