Última Bioerosion of the coralline alga Hydrolithon onkodes by microborers in the coral reefs of Moorea, French Polynesia ArchiMer Tribollet, A; Payri, C. Calcareous skeletons of the coralline alga Hydrolithon onkodes are colonised by a variety of microboring organisms including euendolithic algae. The species composition of microboring organisms as well as the boring patterns and the boring activity differ between live and dead coralline crusts. The microborers inhabiting the live crusts form an obvious, macroscopically visible green layer in the basal part of the crust, which is in contact with the substratum underneath. Some species, primarily Plectonema terebrans (83 %) and Ostreobium quekettii (7 %) grow from the inside towards the crust's surface and produce a dense network of branched filaments. Following the death of the coralline alga, the skeletons are colonised at the surface and bored inward by...

Bioerosion by grazing and boring organisms is one of the major destructive forces operating on reef. The aim of this study was to estimate the intensity of internal bioerosion by both microflora and fauna of Acropora, a branching scleractinian, on the reef flat at La Saline (Reunion, Indian Ocean). Internal bioerosion was estimated at two sites, varying in degrees of eutrophication. At each site, dead Acropora subjected to heavy grazing or covered by algal turf were examined. Acropora formosa is subjected to high bioerosion due to its high porosity and its branching form, which facilitates colonisation by boring organisms. Three endolithic microflora species, Plectonema terebrans, Mastigocoleus testarum and Ostreobium queckettii colonised the branches. The...

Ano: 2001 URL: http://archimer.ifremer.fr/doc/00322/43353/42860.pdf Caractéristiques du feutrage algal des récifs coralliens de Polynésie française soumis à différentes intensités de bioérosion ArchiMer Le Bris, S; Le Campion-alsumard, T; Romano, Jc. This study deals with the colonisation of experimental Porites blocks by epilithic and endolithic algal community in two atoll lagoons and two high-island lagoons in French Polynesia, exposed to different environmental conditions during a 5-year period. A qualitative analysis of the community (cyanobacteria and micro-algae) was carried out, and the relationship between the epilithic and endolithic strata observed. HPLC analysis of chlorophyll pigments was used to quantitatively determine the plant biomass, which was then compared to that of the algal turf of neighbouring reefs. The results show that these blocks are colonised according to two factors: the reef structure (atoll or high-island) and the degree of human disturbance. The epilithic and...
