Temperature-Driven Local Acclimatization of Symbiodnium Hosted by the Coral Galaxea fascicularis at Hainan Island, China
The success of coral reef ecosystems largely depends on mutualistic symbiosis between scleractinian corals and the dinoflagellate photosymbiont Symbiodiniurn spp. However, further investigation is needed to elucidate the flexibility of coral-algae associations in response to environmental changes.
