“…Settlement tiles, deployed in 3-4 m depth along the reef edge, were revisited every 4 months in order to detect changes between wet, transition and dry seasons. Terracotta tiles (Harriott and Fisk, 1987;Maida et al, 1995;Dunstan and Johnson, 1998) (15 Â 15 cm) were connected pairwise by a stainless steel bolt, with the unglazed faces exposed and the glazed faces touching each other (n = 16 tile pairs for each site). The bolt holding the tiles was fixed at an angle of 45°on dead coral boulders.…”

a b s t r a c tCoral recruitment was assessed in highly diverse and economically important Spermonde Archipelago, a reef system subjected to land-based sources of siltation/pollution and destructive fishing, over a period of 2 years. Recruitment on settlement tiles reached up to 705 spat m À2 yr À1 and was strongest in the dry season (July-October), except off-shore, where larvae settled earlier. Pocilloporidae dominated nearshore, while a more diverse community of Acroporidae, Poritidae and others settled in the less polluted mid-shelf and off-shore reefs. Non-coral fouling community appeared to hardly influence initial coral settlement on the tiles, although, this does not necessarily infer low coral post-settlement mortality, which may be enhanced at the near-and off-shore reefs as indicated by increased abundances of potential space competitors on natural substrate. Blast fishing showed no local reduction in coral recruitment and live hard coral cover increased in oligotrophic reefs, indicating potential for coral recovery, if managed effectively.

“…on the brooded planulae of Acropora palifera and Stylophora pistillata and suggested allelopathy as the mechanism. Similarly, Maida et al (1995) showed allelopathic effects for 2 species of soft corals on scleractinian recruitment. However, an alternative to allelopathy is the hypothesis that pathogens associated with the algae are responsible for the observed negative effect (Nugues et al 2004b).…”

Coral recruitment is a key process in the maintenance and recovery of coral reef ecosystems. While intense competition between coral and algae is often assumed on reefs that have undergone phase shifts from coral to algal dominance, data examining the competitive interactions involved, particularly during the larval and immediate post-settlement stage, are scarce. Using a series of field and outdoor seawater table experiments, we tested the hypothesis that common species of macroalgae and cyanobacteria inhibit coral recruitment. We examined the effects of Lyngbya spp., Dictyota spp., Lobophora variegata (J. V. Lamouroux) Womersley, and Chondrophycus poiteaui (J. V. Lamouroux) Nam (formerly Laurencia poiteaui) on the recruitment success of Porites astreoides larvae. All species but C. poiteaui caused either recruitment inhibition or avoidance behavior in P. astreoides larvae, while L. confervoides and D. menstrualis significantly increased mortality rates of P. astreoides recruits. We also tested the effect of some of these macrophytes on larvae of the gorgonian octocoral Briareum asbestinum. Exposure to Lyngbya majuscula reduced survival and recruitment in the octocoral larvae. Our results provide evidence that algae and cyanobacteria use tactics beyond space occupation to inhibit coral recruitment. On reefs experiencing phase shifts or temporary algal blooms, the restocking of adult coral populations may be slowed due to recruitment inhibition, thereby perpetuating reduced coral cover and limiting coral community recovery.

“…Having the structural flexibility to tolerate this type of condition, soft corals are able to thrive on the exposed side of reefs (Hong and Sasekumar, 1981). The other factor that influences the growth of soft corals is the ability to inhibit the growth of their adjacent hard corals by releasing toxins (Maida et al, 1995;Fabricius, 1998). Hence, soft corals are able to grow and compete with hard corals to dominate certain areas of the reefs.…”

IntroductionCoral reefs are important ecosystems that provide goods and services to marine tropical and subtropical regions (Moberg and Folke, 1999). In Peninsular Malaysia, coral reefs are found in several localities off the west coast, south coast, and east coast of the peninsula (Affendi and Rosman, 2012). The east coast of Peninsular Malaysia has extensive development of coral reefs with a total of 323 scleractinian coral species identified (Harborne et al., 2000). The most recent report on the status of hard coral diversity increased this list to 431 species in this region (Affendi and Rosman, 2012). This figure represents approximately 75% of the total number of 571 coral species identified in the South China Sea (Huang et al., 2015).Although coral reefs provide various important ecosystem services to human populations, their health status has been declining due to human intervention together with detrimental impacts of climate change and ocean acidification (Wilkinson, 2008;Jordan et al., 2010;Unsworth et al., 2010). Reef Check Malaysia reported that the coral coverage in several reefs of the east coast region was exposed to high rates of sedimentation resulting from construction and land reclamation activities (Reef Check Malaysia, 2008). These pressures affect reef diversity and distribution by reducing light availability. In addition, tourism activities may also be a major impact causing a decrease in live coral coverage (Jonsson, 2003;Toda et al., 2007). Trampling action by inexperienced snorkelers and scuba divers may have a negative impact that can cause partial mortality of corals (Zakai and Chadwic-Furman 2002;Toda et al., 2007). Besides the natural and anthropogenic factors, the lack of a comprehensive database is impeding conservation efforts towards coral reef ecosystems. Therefore, management action based on comprehensive studies of marine biodiversity should be performed to ensure the conservation and sustainability of coral reef ecosystems.Several studies about coral species diversity were conducted at Tioman Island by Harborne et al. (2000) at seven reef sites, i.e. Batu Malang, Juara Bay, Gut, Tokong Bahara, Seri Buat, Tulai, and Renggis Islands; by Affendi et al. (2007) at several reef sites from Paya to Genting villages; and by Amri et al. (2008) at one reef site in Tekek Bay. The most recent study of generic coral diversity was done by Toda et al. (2007) at three reef sites, i.e. Manggo, Tulai and Renggis Reefs, at this island. It is an important task to keep up-to-date list of corals and perform a continuous evaluation of the status of coral diversity and reef conditions at Tioman Island.This present study describes the generic diversity and distribution of corals at 13 reef sites in the east coast, west coast, and isolated areas of Tioman Island. The classification of coral morphology class score and the coral condition for each reef site were also determined. Data
