| Research Abstract |
I conducted field experiments testing(1) relationship among corals, algae, and herbivorous fish, and(2) effects of corallivorous fish on growth of small corals, using coral transplant technique. In experiment(1), small fragments of Acropora were placed inside and outside cages ; growth of the transplanted fragments inside the cage were negatively affected by turf algae. In experiment(2), small fragments of Acropora that were transplanted to low coral density and coverage were damage more frequently than those at high density and coverage.
