Appendix B (Table B1). SNK tests conducted after ANOVAs comparing total invertebrate abundances, number of invertebrate families, and total infaunal and epifaunal abunundances from benthic cores collected at different depths and within both vegetated and unvegetated habitats. ANOVA results are reported in Table 6. Factors in ANOVAs were site (random, 2 levels), depth (fixed, 3 levels: deeper subtidal, D, shallow subidal, S, and intertidal, I), habitat (fixed, 2 levels: vegetated and unvegetated habitat), and time (fixed, 2 levels: October and May sampling). n = 8.
