A Bray-Curtis resemblance matrix was generated from a matrix of presence/absence data from 12 combined roving surveys and rotenone collections in order to produce a non-metric multidimensional scaling (MDS) ordination and group averaged hierarchical clustering dendrogram in PRIMER v. 6.1 software 11. The ANOSIM statistic was employed to test for a priori differences between habitat types and depth classes. A dendrogram based on group averaged hierarchical cluster techniques was used to illustrate the differences among depth classes (Figure 202). Color codes are derived from the similarity profile (SIMPROF) statistic in Primer 6.1. SIMPROF is less powerful than ANOSIM, intended for a posteriori tests of structure in the data. The test was employed here for representational purposes. A second data matrix of species presence and absence was introduced for an a posteriori test of genuine data structure among Caribbean localities, using the Bray-Curtis resemblance measure to determine the level
