Coral symbiont biodiversity and climate change adaptation

Using genetic analyses, researchers report that the prevalent coral symbiont to live in the high salinity and extreme temperatures of the Persian/Arabian Gulf, Symbiodinium thermophilum, may have originated from an ancient and genetically diverse group found outside the Persian/Arabian Gulf at barely detectable levels, findings that highlight the importance of maintaining biodiversity for future climate change adaptation. - See at
