Response of fluorescence morphs of the mesophotic coral Euphyllia paradivisa to ultra-violet radiation.

摘要: Euphyllia paradivisa is a strictly mesophotic coral in the reefs of Eilat that displays striking color polymorphism, attributed to fluorescent proteins (FPs). FPs, which are used as visual markers biomedical research, have been suggested serve photoprotectors or facilitators photosynthesis corals due their ability transform light. Solar radiation penetrates sea includes, among others, both vital photosynthetic active (PAR) and ultra-violet (UVR). Both types, at high intensities, known negative effects on corals, ranging from cellular damage changes community structure. In present study, fluorescence morphs E. were investigate UVR response organism examine phenomenon polymorphism. paradivisa, although able survive high-light environments, displayed several physiological behavioral responses indicated severe light stress. We suggest PAR potential drivers behind absence this shallow reefs. Moreover, we found no significant differences between different morphs' evidence either photoprotection enhancement. therefore FPs might biological role than previously hypothesized for corals.
