摘要: To test the hypothesis that algal symbionts make coral larvae more susceptible to high photosynthetically active radiation (PAR) and ultraviolet (UVR), symbiotic non-symbiotic planulae of Acropora tenuis were exposed natural sunlight (high PAR UVR) at an ambient temperature approximately 27°C for 4 d. DNA damage to host cells was detected using a comet assay (single-cell gel electrophoresis). Coral from had longer tails than those planulae, indicating in larvae had damage larvae. This result suggests algae are source oxidative stress under conditions ocean surface.
