Outer fringing sites (e.g. Paradise and Fundo Outer) have higher protection from bleaching by cooling due to their proximity to deeper cooler water and the potential for upwelling. Resilience potential at sites with higher coral cover (e.g. Misali, Manta and Mandela) is driven by healthier ecological interactions (e.g. coral associates), more favourable benthic quality and higher shading potential due to higher topographical complexity. Connectivity and Anthropogenic threats have the shortest vectors and thus have the least influence on the trends displayed. The Multi-Dimensional Scaling plots below show the relative quality of each resilience factor at each site. Short descriptions of main findings are provided to the right of the plots. 33
