Key output includes the p-value, the coefficients, R 2, and the residual plots. Two samples sharing the same species in the same abundances have the highest similarity (and lowest distance), and the similarity decreases (and distance increases) with the differences in their species composition. Pairwise ANOSIM comparisons indicated the most significant differences occurred between soil and the three lithic niches (P = 0. Bunch, Megan E. The statistical significance of observed R is assessed by permuting the grouping vector to obtain the empirical distribution of R under null-model. 05 level are marked by **, and values significant at the 0.

This is also reflected in the results of a nested ANOSIM to test for pairwise differences between groups. Caskey, Aubrey R. Despite statistical significance, both the R 2 value from adonis results and the R-statistic from anosim results suggest that the biological relevance of the differences between states was not high (see Figure 6—source data 1). Figure 7 shows that all within-MC pairwise comparisons and the dispersion of all pairwise comparisons are significantly smaller in NG-Tax meaning that distances within and between MC types are robust. Bradley1, Daniel O. A global one-way ANOSIM showed this variation was significant (global R = 0. A new statistical approach for assessing similarity of species composition with incidence and abundance data. 30 and a maximum of 0. 0 suggests maximum dissimilarity.
