a. Results of the two-way ANOVA applied on the relative abundance of ecological guilds to test differences among sampling approach (T vs T + MH) and HS classes. b. Results of the two-way ANOSIM applied on the number of species belonging to different ecological guilds to test differences among sampling approach (T vs T + MH) and HS classes; c. Results of the SIMPER analysis reporting the contribution of each ecological guilds. Groups are ordered based on their contribution to dissimilarity. Av. Dissim = average dissimilarity; Contrib. % = contribution of each group to dissimilarity; Cumulative % = cumulative contribution of each group to dissimilarity; Mean T = mean abundance of each group in T; Mean MH + T = mean abundance of each group in MH + T. T = traditional approach; MH = sampling in microhabitats; T + MH = experimental approach.
