Devon Merlino Symbiodinium and its Symbiotic Relationship with Coral Reefs Abstract Coral reefs have been a phenomenon for many years, often puzzling marine biologists between random acts of coral bleaching or the death of a coral reef in its entirety. Global warming and rising sea temperatures has had a major effect on coral communities, often causing mass coral bleaching events that wipe out coral communities. The migration of invasive algae, Symbiodinium, has allowed for the protection of coral reefs against rising sea temperatures. Although protecting the coral reefs from bleaching events, the presence of Symbiodinium trenchii causes a decreased rate of calcification, the process by which new coral reefs are built. A study conducted in the Persian/Arabian Gulf sampled coral located in the hottest sea locations. These samples underwent genetic testing and Hume et al. (2015) concluded that a new species of Symbiodinium was present in the gulf. Another study performed by Keshavmurthy et al. (2014) in Taiwan took samples from eight water regions. The samples underwent Restriction Fragment Length Polymorphism, along with other genetic tests. It was determined that thermally tolerant clade C was present in the tested water regions. Much of the abnormal existence of Symbiodinium among various coral reefs demonstrates the impact of invasive species among ecological environments. The impact of the algae on the environment has both helped and hindered coral communities. As
