Figure 3. Pair-wise comparisons of fish assemblages among locations at each depth.

Graphical representation of PERMANOVA pair-wise tests comparing fish assemblages among locations separately for each depth stratum on the basis of the Jaccard resemblance measure. Triangle side lengths are proportional to the Jaccard dissimilarities between location centroids. Circle radii are proportional to a pseudo multivariate standard error around the group centroid for each location within each depth. Due to the large number of comparisons, a conservative significance level of α = 0.01 was used. Significant differences (p<0.01) are marked by an asterisk (*). Partitioning was done using Type I (sequential) sums of squares and P-values were obtained for each term using 9999 permutations under the reduced model. Similar results were obtained using the taxonomic resemblance measure Г⁺.
