Results of two-way ANOVA testing differences in sediment variables (A.) and bivalve variables (B.) between areas with and without hard structure) and among sites in Mission Bay.

Structure presence/absence was treated as a fixed variable, while site (block) was designated as a random variable. N = 60 samples (6 each per 10 sites) V.p. = Manila clam (Venerupis philippinarum). Average (±standard error) of raw (untransformed) variables in the presence and absence of hard structure are shown; bold indicates significant difference between the presence and absence of structure. Significance was determined using Bonferroni adjusted alpha value (initial α = 0.05).
