Fig. 1: Morpho-functional groups of Caribbean corals and their susceptibility to stony coral tissue loss disease (SCTLD).

a Hierarchical clustering dendrogram based on a Gower dissimilarity analysis and heat map representation of functional traits. Numerical values from 1 to 5 correspond to the categories listed in Table S6. The variation in color intensity within each group (light to deep) corresponds to the trait numerical value (given inside each square). b Prevalence of SCTLD for coral species across 101 reef sites in the Mexican Caribbean (n = number of colonies). We included coral colonies with total mortality whose deaths could be attributable to SCTLD. The shaded area corresponds to the prevalence of SCTLD for each morpho-functional group in (a). The asterisk (*) indicates species with >10% disease prevalence (these were considered highly susceptible species, see Methods for more details). c Pseudodiploria strigosa colony with the characteristic lesions produced by SCTLD in Puerto Morelos (July 2018). d Dendrogyra cylindrus colony afflicted with SCTLD showing extensive recent mortality in Sian Ka’an (September 2018). e A recently deceased colony of Meandrina sp. (covered by a homogenous, thin layer of filamentous algae) in Akumal (September 2018). Photo credits: Lorenzo Alvarez-Filip.
