Figure 4. Mean number of individuals per quadrat (¡SE; n56) and mean shell length (mm; ¡SE; n is variable) in the two areas (southern and northern) and in the different tidal levels (in relation to MLW) in Caraguatatuba Bay. The comparisons (one-way ANOVA) among tidal levels within each area are presented in Table I. The letters (southern) and the numbers (northern) represent the results of the a posteriori SNK test. The horizontal bar indicates non-significant differences in the SNK test.
