Corals are bleaching at unprecedented rates due to global warming. The Caribbean has lost 70% of hard coral cover since the 1970s. However, some corals are more resilient to bleaching than others because they are associated with heat-tolerant symbiont algae. We want to examine coral-symbiont associations in the Caribbean to determine which corals in the community are most likely to survive future bleaching events and if these corals are in need of restoration.
