Fig. 50. nMDS plot showing relationship between surveyed fish abundance and vertical relief of the reef. Each point is an individual site.

Fish abundance also was not related to coral cover (Fig. 49a) or vertical relief (Fig. 50), but it was related to macroalgal cover (Fig. 49b), although the R value was low (Table 7). The PRIMER grouping factor for average benthic relief associated with each site was as follows: 1(0-40cm), 2(40-50cm), 3(50-60cm) and 4(60+cm).

Table 7. 1-way ANOSIMS performed on the various habitat variables in relation to the surveyed fish abundance. R and p values are reported and significant results are in bold.
