Non-metric multidimensional scaling ordination (nMDS) representing the Symbiodinium genetic structure from the resemblance matrix of Pocillopora damicornis and Stylophora pistillata centroids belonging to samples collected from 2010 to 2012. The nMDS showed a temporal partitioning within hosts of the Symbiodinium types divided into two distinct groups: May 2010, September 2010 and March 2011 are clustered together while September 2012 is widely separated. This highlights a substantial change in the structure of Symbiodinium assemblage 18 months after the second bleaching event. The bar chart represents the average of Shannon diversity over time within the two Pocilloporidae coral species. Error bars represent 95% confidence interval (Cl).
