Detailed Results 4.2 Coral community structure Number of genera 45 40 35 30 25 20 15 Site diversity The total number of coral genera found was 47, with a maximum of 42 found in healthy Misali and a minimum of 23 in degraded Paradise. Fundo Lagoon, The Hole and Msuka Bay also have low diversity, probably due to their geographical position and lack of local connectivity to larval sources. 10 5 0 Misali Mandela Kokota Fundo Inner Njao Gap Manta Swiss Fundo Outer Simba The Hole Msuka Bay Fundo Lagoon Paradise Paradise Fundo Outer Fundo Lagoon Simba The Hole Swiss Njao Gap Manta Fundo Inner Kokota Mandela Resemblance: S17 Bray Curtis similarity 2D Stress: 0.11 Msuka Bay Similarity 70 In a Multi-Dimensional Scaling plot, the main outliers are the degraded Paradise and Fundo Outer sites, as well as the low diversity habitats Fundo Lagoon, The Hole and Msuka Bay that probably receive less coral larvae than the fringing and tidal channel reefs. Other sites show a homogenous composition of coral genera. Misali 21

The number of sites shows genera present at all sites (p=1) to those present in only one site (p>0), with a red line and squares. The blue line with diamonds combines information on relative abundance of each genus at each site. 47 genera were recorded, with Porites being dominant, followed by Galaxea and Acropora. The relatively smooth initial descent of the Relative abundance line shows that coral communities are relatively homogenous, with the steeper descent toward the end of the line indicating rare genera. 10 genera were present at every site, and 35 genera (75% of genera recorded) were found at > 70% of sites. One genus was found at only one site (Msuka Bay) – Heliopora. 22
