3.3. Changes in density of juvenile corals
The means of the densities of juvenile corals during the study periods at Ao Thong Tanote were 0.17–0.35 colony m−2 while those at Ao Thong Krut were 0.14–0.32 colony m−2 (Fig. 9). The densities of juvenile corals between the years 2004–2006, 2004–2008, 2006–2010, and 2008–2010 were significantly different (Table 3). The dominant juvenile corals at both study sites were P. lutea, Favia spp., Favites spp. and Pocillopora damicornis ( Fig. 10, Fig. 11 and Fig. 12). Juveniles of Acropora spp. were also abundant at Ao Thong Krut in the year 2008. The compositions of juvenile corals at both study sites were much changed during the study periods.
