 3.3.2 Beals Island 



3.3.2.1 Assemblage Structure 



ANOVA of Beals Island infaunal taxa richness data indicated that sites differed 

 significantly (p<0.05) among years (Table 3-14). Linear contrasts of site by year means 

 showed that constructed flat values differed from reference values (p<0.01) only in 1992 

 (Table 3-14) when taxa/core were highest at the constructed flat (Figure 3-20). Total 

 numerical abundance also differed among sites over time, however, abundances were far 

 greater at the reference area than the constructed flat (Figure 3-21) in all years except 1991 

 (Table 3-15). Total biomass was higher at the reference area than the constructed flat in all 

 years except 1994 (Table 3-16; Figure 3-22).
