“…Perry (1998) demonstrated that bioerosion rates in dead coral substrata also increased from 5 to 30 m depth, and suggested that this increase might be due to a depth-dependent decline in calcification rates and skeletal densities (Bosscher 1993). However, other studies did not find any correlation between depth and internal macrobioerosion intensity Londoño-Cruz et al 2003).…”

“…Although strongly related to turbidity, chlorophyll a and depth, internal macrobioeroder densities in massive Porites are also affected by a number of other biotic and abiotic factors Perry 1998;Londoño-Cruz et al 2003). For instance, sedimentation may affect the abundance of some bioeroders by blanketing the habitat available for settlement , and strong water currents are also related to high abundances of some filter feeders such as lithophagids Londoño-Cruz et al 2003).…”

For macrobioeroders recruiting as pelagic larvae, local currents might influence their recruitment (Osorno et al 2005), and the presence of conspecifics might be a cue to settlement.…”

This study investigates the relationship between the density of internal macrobioeroders in living massive Porites and nutrient status. The study was conducted along turbidity and chlorophyll gradients towards river mouths on 12 reefs in four regions of the inshore Great Barrier Reef. Mean internal macrobioeroder densities doubled from 2 to 8 m depth, and at the 8 m sites, densities increased 4-to 7-fold towards the river mouths in all regions. Densities also increased 1.6-fold for each additional 1 NTU turbidity and 650-fold per 1 lg L -1 additional chlorophyll a. The study shows that the density of macrobioeroder boreholes in living massive Porites is a simple bioindicator measure for changing turbidity and chlorophyll concentrations on the Great Barrier Reef for sites from which direct water quality measurements are unavailable.

“…Biological erosion (bioerosion) as a general term refers to the destruction and removal of consolidated minerals of lithic substrate by the direct action of organisms (Neumann, 1966). The most common agents of bioerosion are fish (Risk and Sammarco, 1982), sea urchins (Mokady et al, 1996), algae (Kobluk and Risk, 1977), molluscs (Londono-Cruz et al, 2003;Hutchings et al, 2005), polychaetes and sipunculids (LondonoCruz et al, 2003) and sponges Hutchings et al, 2005). Physical erosion is caused by wave movement, storms, etc.…”

SUMMARY Bioerosion by boring sponges is an important mechanism shaping the structure of coral reefs all around the world. To determine the excavation rate by boring sponges, we developed a system in which chemical and mechanical boring rates [calcium carbonate (CaCO3) dissolution and chip production, respectively] were measured simultaneously in experimental tanks containing reefal rock inhabited by a boring sponge. Pione cf. vastifica (Hancock 1849) was chosen as a model species to study the erosion rate of boring sponges. It is an abundant species in the coral reefs of the Nature Reserve Reef, Elat, Gulf of Aqaba, northern Red Sea, reaching maximum abundance at 25-30 m. The rate of chemical bioerosion was determined from the increase in tank-seawater alkalinity over time, and the mechanical bioerosion rate was estimated from the total amount of CaCO3 chips produced over the same time interval. The measured bioerosion rate of P. cf. vastifica was 2.3 g m-2 sponge day-1, showing seasonal but not diurnal variations, suggesting that the zooxanthellae harboring the sponge have no effect on its boring rate. The experiments indicated clearly that per each mass of chips that P. cf. vastificaproduces during its boring activity, it dissolves three masses of reef CaCO3 framework. Assuming that some additional boring sponges can use a similar strategy of bioerosion, these findings suggest that chips, the most obvious erosion products of boring sponges, represent only a small fraction of boring sponge bioerosion capacity.

With the intention of knowing if coral associates can be used as indicators of coral reef status, we studied organisms associated with live scleractinian corals on different sites located around Hoga and Kaledupa islands in the Tukang Besi Archipelago of the south-eastern coast of Sulawesi in the Banda Sea, in Indonesia. Twenty meter long line intercept transects were used to estimate the number of coral colonies infested by coral associates. The number of coral associates found on each coral colony on the transect was recorded and corals were identified to the most precise level. Massive and encrusting coral colonies were also measured in order to estimate the densities of infestation per square meter of coral colonies. To link the assemblages of coral associates observed with the characteristics of the benthic habitats, the coral cover was estimated using a 0.5 m point intercept transect method.Three hundred seventy-six colonies (45%) were infested by a total of 2,815 coral associates. In total, coral associates amounted to 2,062 lithophagid bivalves (73% of total coral infestations), 306 dwelling hermit crabs of the genus Paguritta (10.9%) and 242 vermetid snail Dendropoma maxima (8.6 %). The most infested colonies belonged to the genera Montipora, Pavona and Porites. They represented 33%, 23% and 18% of the total number of colonies infested respectively. The highest densities of infestation were found for the boring Lithophaga spp. for which a density of 88 ind/m2 was noticed in encrusting corals of the genus Pavona.The density of lithophagid bivalves and the number of infested colonies were high in the most impacted site (Sampela) and one of the intermediately impacted site (Pak Kasim's) whereas they were low in the most pristine site (Kaledupa). The other intermediately impacted site (Buoy 3) had an intermediate number of infestations. Despite the lack of any significant difference in biotic cover between the most pristine site and the intermediately impacted sites, a common gradient tends to emerge based on coral associates. Although having a high biotic cover, Pak Kasim's suffers from a similar level of infestation as Sampela suggesting process of reef degradation previously experienced by the most impacted site. Our results suggest that coral associates can be used as indicators of coral reef status.
