Figure legends
Figure 1 . Composite plots of sea surface temperature regimes at Baltra, Guy Fawkes and Cuatro Hermanos (the reference site for Rocas Beagle) during the period of coral bleaching. Line color corresponds with temperatures recorded at 6 m (red) and 15 m (blue). Dashed lines correspond to the threshold cold temperatures (18oC and 16oC) that induce bleaching in Pocilloporacorals.
Figure 2. (A) Status of coral heads (by % surveyed with certain tissue characteristics) and (B) mean and standard error of overhead surface area of live (black) and dead (gray) coral heads across the time series (July 2008 to February 2010). Dead corals (but not live corals) were also surveyed in July 2011. (C) The same tagged coral head, surveyed in (C) July 2008 and (D) February 2010.
Figure 3 . Mean and standard deviation of species accumulation curves (SACs) of randomized observed associated species richness with live (black) and dead (gray) Pocillopora corals. Associated species include (A) all surveyed species, (B) fishes and (C) mobile macroinvertebrate species. Blue and red underlining indicates La Niña and El Niño periods, respectively.
Figure 4. Means and 95% confidence intervals of Chao 1 estimated species richness of (A) all surveyed (total) species, (B) fishes and (C) mobile macroinvertebrates on live (black) versus dead (gray) corals at each survey date between July 2008 and February 2010. Note different scales on y-axis. Means with 95% confidence intervals that do not overlap the mean of the other group under comparison are significantly different (Ramsey & Schafer 2012).
Figure 5 . Species composition of coral-associated fishes and mobile macroinvertebrates surveyed on live versus dead coral heads at each survey date between July 2008 and February 2010. (A) Biplot of loadings for principal component 1 (PC1) by principal component 2 (PC2) from a principal components analysis (PCA) using abundances of coral-associated macrofauna as the response variables and treating each individual coral head in each survey as an individual sample. PC1 accounted for 24% of total variation in composition, while PC2 accounted for 15% of total variation in composition. Points refer to the community assemblage associated with individual corals, including live (square symbols) and dead (circle symbols) corals, sampled at each of four time points (represented by different colors). The ellipses show the 95% confidence regions for the mean centroids of each survey group (live or dead corals) surveyed at a specific date. Raw abundance of (B) fishes, (C) crustaceans and echinoderms, and (D) gastropods counted on live and dead corals across all survey dates. Asterisks (**) indicate species that are endemic to the Galápagos; “other sp. Unknown 1 ” and “other sp. Unknown 2 in part (C) refer to unidentified crustaceans.
Figure 6 . Species-Area relationships, regressing estimated total richness against coral overhead surface area for individual dead or live coral heads at each survey date between July 2008 and February 2010. Regression line equations, r-squared values and p-values for significant relationships are shown. Note that dead corals did not exhibit significant S-A relationships in July 2008 and January 2009.
