| Research Abstract |
Recent and Quaternary fossil coral reefs were studied in Ishigaki-jima, Irabu-jima and Kikai-jima in the Ryukyu Island, Japan from July to August 2001. The recent coral communities were recorded by a quantitative method with quadrat (1 m^2 in area) along the coast of Shiraho coral reef in the Ishigaki-jima. Pleistocene communities were also investigated on vertical outcrops in the Kikai-jima and Irabu-jima with quadrat methods.
Coverage of the recent hermatipic coral communities was estimated with sketches and photographs which were taken through the field studies. Relative abundance of each species was calculated by using software for image analysis (NIH Image). Community successions of the hermatypic corals through the Holocene sea-level changes were reconstructed on the outcrop at Kamikatetsu coast of the Kikai-jima. Pleistocene coral successions were analyzed on the outcrops at Shidooke, Kikai-jima.
