Coral-associated microbial symbionts, particularly dinoflagellates from the family Symbiodiniaceae, play a significant role in corals’ ability to survive and recover from marine heatwaves and mass bleaching events. Yet, there remain limited data on the extent to which microalgal endosymbiont associations shift in situ during and after prolonged heat stress and over small spatial scales, potentially limiting the alteration of symbiont communities as a restoration tool. In 2019, Mo’orea, French Polynesia experienced a massive thermal anomaly accompanied by widespread coral bleaching and mortality. Using ITS2 amplicon sequencing, we assessed the possibility of microalgal assemblages explaining the observed variability inAcropora hyacinthusthermal tolerance and recovery dynamics between reef habitats. Our data reveal flexibility inA. hyacinthussymbiont associations, but show that these associations were strongly linked to both heat stress response and the reef habitat in which the colony resided, indicating a prominent role of local environments in shaping in hospite symbiont communities and, consequently, holobiont thermal tolerance. Notably, bleaching resistant colonies were invariably dominated bySymbiodiniumduring and after the bleaching event.Although we did not detect temporal changes in symbiont communities during recovery from thermal stress, this novel observation ofA. hyacinthusin association withSymbiodiniumsuggests that heat stress may have facilitated a shift. Further, we identify symbiont type profiles that are potentially diagnostic of bleaching susceptibility. Our findings illuminate the extent of symbiont flexibility for this species and location, with important implications for coral reef recovery and management in a rapidly changing ocean.
