The catastrophic bleaching phenomenon is being noticed in several parts of the world since April 2010. Even though the Gulf water corals are accustomed to higher temperature and salinity fluctuations, they are also prone to extreme temperature anomaly (Riegl, 2003). This evidences the recent global mass bleaching and its influence on the Scleractinian corals of Abu Al Abyad Island of Abu Dhabi (United Arab Emirates). The coral reef strength of Abu Al Abyad has significantly reduced after 1998 and 2002 bleaching phenomena (Thabit, 2002). Coral propagation study has been already initiated to restore the coral reefs in the vicinity of this island. After the global alarming of this mass bleaching, the Scleractinian corals of this island are monitored for bleaching event since April, 2010. Eventually, the bleaching symptom was initially observed in the transplanted corals Acropora arabensis in the mid of July. The rightmost nubbin of the table was taken as a reference for the recovery study (Fig. 1). The temperature logger data revealed that, the water temperature has risen up to the maximum of 37°C in the month of July. However Zooxanthellae were expelled, the corals were noticed with active polyps in the study site. The selected nubbin was revisited at once in two months to observe the recovery pattern. The Zooxanthellae were initially reassembled at the base of the nubbin and gradually progressed towards the apex.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
