A. Percent cover of Porella proboscidea at four depths. 

 Means (inner and outer) at 30 m differ significantly from 

 those at all other depths (ANOVA, p < 0.05, 7, 33 df, F= 

 4.8) . 



B. Percent cover of Celleporella hyalina at four depths. 

 Means (inner and outer) at 30 m differ significantly from 

 those at all other depths (ANOVA, p < 0.05, 7, 33 df, F = 

 77.5) . 



C. Percent cover of Lepralia americana at four depths. Mean 

 (inner) at 80 m differs from all other means. Mean (outer) 

 at 65 m differs significantly from all other means (ANOVA, 



p < 0.05, 7, 33 df, F = 21.4). 



D. Percent cover of Callopora craticula at four depths. 

 Means not significantly different for any group (ANOVA, 

 p > 0.05, 7, 33 df , F = 0.9) .
