Species community database
Coral species presence and absence data were compiled from 2396 reef sites from 26 countries for the reef crest zone and 5091 reef sites from 30 countries for the midslope zone (Figure 1). Full community data (containing a 0 or 1 value for all 14 common coral species groups) were available for all time periods and were compiled from 1569 reef sites from 24 countries for the reef crest and 3207 sites from 27 countries for the midslope zone (Tables S3,S4).
