Unique quantitative Symbiodiniaceae signature of coral colonies revealed through spatio-temporal survey in Moorea.

ABSTRACT: One of the mechanisms of rapid adaptation or acclimatization to environmental changes in corals is through the dynamics of the composition of their associated endosymbiotic Symbiodiniaceae community. The various species of these dinoflagellates are characterized by different biological properties, some of which can confer stress tolerance to the coral host. Compelling evidence indicates that the corals' Symbiodiniaceae community can change via shuffling and/or switching but the ecological relevance and the governance of these processes remain elusive. Using a qPCR approach to follow the dynamics of Symbiodiniaceae genera in tagged colonies of three coral species over a 10-18 month period, we detected putative genus-level switching of algal symbionts, with coral species-specific rates of oc
