Results of the permanova analysis showing differences between ‘shelf’ (i.e. reef locations: nearshore vs. offshore), ‘season’ (i.e. sampling date: summer vs. winter) and ‘exposure’ (i.e. fore‐/back‐reef environment: exposed vs. sheltered). Results of SIMPER analyses showing main factors contributing to a total of >90% of the observed differences between sampling dates and shelf locations, respectively.
