| In order to estimate the losses of CaCO3 from bioerosion (grazing and boring), experimental coral substrates were laid in the lagoons of high islands and atolls in French Polynesia. After six months of exposure, the sites could be divided into those exhibiting net bioerosion and those exhibiting net accretion. Of the five sites exhibiting net bioerosion (grazing and macroboring greater than accretion), three were located off high islands and two in atoll lagoons. The average net rate of bioerosion was greatest at Faaa in Papeete Bay, Tahiti (10.45 kg.m(-2).yr(-1)). Of, the two sites exhibiting net accretion, the greatest rate of gain (0.81 kg.m(-2).yr(-1)) was recorded at the eastern site in Takapoto lagoon. Recorded differences in the composition and... |
