Research Abstract |
To quantify Symbiodinium released from corals, traps were set to the branches of corals and the contents were subjected to quantitative PCR, which enable to detect each ribotypes. In the results, we found significant amount of Symbiodinium were released from the branches, but the released ribotypes were not congruent to those in the coral tissues, rather, heat-tolerable ribotypes were few among the released ones. In other results, we also found that released Symbiodinium biomass accumulated in the surrounding waters and may become“source”to next coral hosts.
