Cover Story: Thermal stress drives the bleaching of reef corals and alters their mutualistic relationship with Symbiodiniaceae endosymbionts. In 2016, a major global-scale bleaching event hit countless tropical reefs. Our study analysed the relative abundances of Cladocopium and Durusdinium in bleached and healthy colonies of the common coral Pachyseris speciosa in Singapore during and after the bleaching event. Given the importance of specific endosymbiont taxa for thermal tolerance, it is surprising that bleached tissue showed limited change compared to healthy tissue during the bleaching event. However, Symbiodiniaceae communities appear to be more homogeneous during the mass bleaching than before and after the event, suggesting a complex community-level response to bleaching.
