These records are complemented by records from the skeletons of long-lived corals such as Porites. As temperatures rise, mass coralbleachingevents and infectious diseaseoutbreaks are becoming more frequent. The ubiquity of reef-building corals stems from their capacity to support symbiotic unicellular dinoflagellates, from the family Symbiodiniaceae, within their tissues1. When coral bleaching was occurred, there was a significant reduction in Symbiodinium density [ 17 ] and photosynthetic pigments within Symbiodinium cells [ 11 . This dysfunctionality leads to the paling of corals through loss of pigmentation or loss of symbionts more commonly referred to as coral bleaching (Fig. Tables with enumerated lists are used to ensure integrity in naming conventions such tables are denoted with LUT, where LUT stands for look-up-table.
