| Table 10. Results of one way analysis of variance (ANOVA) testing differences in species richness and total abundance among sediment types in Long Island Sound. All data are from Pellegrino and Hubbard (1983). Sediment categories are based on qualitative bulk sediment characteristics (Figure 4). Species richness and abundance are based on all species collected in a 0.04 m2 sample at each sampling site. | ||||||
