Latitudinal Variation into the Macrofaunal Assemblages Associated to Zostera noltei Seagrass along the Atlantic Coast of Morocco

Table 4

Results of two-way ANOVA testing for macrobenthic assemblages’ differences in the total number of individuals (N), total number of taxa (S), biomass (B), Shannon’s diversity index (H′), and Pielou’s evenness index (J′) at the scales of site and position (downstream-upstream) with post hoc pairwise multiple comparisons (Tukey test) among the studied sites.

Tukey’s HSD for site × position
In terms of “Position” effect
	D			MZ ≠ SM ≠ OU = KH = DA				MZ ≠ SM = OU = KH = DA		MZ ≠ SM = OU = KH = DA
	U			MZ = SM = OU = KH ≠ DA				MZ = SM = OU = KH = DA		MZ = SM = OU = KH = DA

Bold values mean that significative differences based on p < 0.05 were detected for the tested effect.
