Dear all,

I think it is worth to highlight the corals of the Persian/Arabian Gulf in this context: The species there are considered to represent mainly a subset of the Indian Ocean community including several cosmopolitan species. Despite being located close to the northern margin of reef distribution, these communities endure regular summer temperatures of 35 deg. C for several weeks (and cold temperatures in winter). So, the origin of the corals plays certainly a defining role in shaping the temperature optimum. Also, evidence is accumulating that the temperature tolerance is shaped by the nutrient environment.
