Coral species richness, evenness and diversity generated by PRIMER, using data from belt transects on 19 reefs, are presented in Table 3. The greatest value of richness and the highest diversity of species was seen at PB-06, while PB05 had the highest value of evenness. In contrast, PB-14 had the lowest value of evenness and diversity and PB-17 had the lowest value of richness. Overall, the most numerous corals were Agaricia, Siderastrea, Porites and the M. annularis complex, respectively. M. annularis exhibited the highest abundance at five sites (PB-01, 07, 18, 20), while large populations of M. faveolata were recorded at six sites (PB-08, 10, 14, 17, 19, 20) and this taxon was dominant at one site (PB-14) (Fig. 14). Agaricia agaricites made up more than 20% of all corals, 4 cm or larger, at 10 of the 19 sites (PB-01, 03, 06, 07, 09, 15, 17, 18, 19, 20) and was the most abundant coral at 9 sites (Fig. 15). Porites astreoides was the most abundant coral at four sites (PB-10, 12, 15, 16) (Fig. 15) while S. siderea was the most abundant coral at 6 sites (PB-02, 08, 11, 12, 14, 16) (Fig. 16). Five reefs contained large monospecific stands of P. porites (PB-04, 09, 10, 13, 18), but it was not numerically dominant at any site.

Fig. 14. Relative abundance (percent of the total population of all species of corals) of each of the four species of Montastraea recorded along belt transects at 19 locations off Pedro Bank, Jamaica. Abundance data are for corals within belt transects that are 4 cm or larger diameter. MANN = M. annularis; MFAV = M. faveolata; MFRA = M. franksi; MCAV = M. cavernosa.
