Symbiotic dinoflagellates associated with corals in Qatar: characterization and physiological response to environmental change by Eldos, Haneen Ibrahim

“…Coral bleaching events witnessed during the last decades in the Arabian Gulf are believed to be the result of the effect of heat events occurring more frequently in the region as a result of the global ocean warming. When corals are under thermal stress, their symbiotic zooxanthellae are affected, and their photosynthetic activity decreases until the stress disappears or until the zooxanthellae are expelled from the coral. …”
