Bioerosion of experimental substrates on high islands and atoll lagoons (French Polynesia) during 5 years of exposure

Relationship of internal macrobioeroder densities in living massive Porites to turbidity and chlorophyll on the Australian Great Barrier Reef

“…relationships (Pari et al 2002;Hutchings et al 2005;Tribollet and Golubic 2005). Most studies that did not find such relationships were conducted on experimental blocks of dead coral substrata with less than 3 years of exposure, rather than in old rubble or live coral (Table 1).…”

“…After *6 months, sipunculans colonise microfractures left by polychaetes. Sponges and bivalves are typically not yet present on blocks after 2 years of exposure but start to appear after 3 years, in sufficient numbers to accelerate the internal macrobioerosion process (Davies and Hutchings 1983;Peyrot-Clausade et al 1992;Chazottes et al 1995;Pari et al 2002).…”

Spondylus crassisquama Lamarck, 1819 as a microecosystem and the effects of associated macrofauna on its shell integrity: isles of biodiversity or sleeping with the enemy?

“…The relationship between bivalves and drilling endobionts are relatively unknown, apart from a few studies on bivalve species of commercial importance (see "Polychaetes", below). To obtain a more detailed picture of the co-existence between S. crassisquama and associated endobionts, we will thus especially discuss the taxa we found that are known for drilling or boring activities and their effects on the Spondylus shell: Sponges Sponges account for a considerable amount of boring in corals (MacGeachy and Stearn 1976; Sammarco and Risk 1990;Pari et al 2002). We were not able to identify the sponge species in our samples, but when breaking and analyzing the shells, we found the typical honeycomb boring style reported for the genus Cliona (Cobb 1969;Rützler and Rieger 1973;MacGeachy and Stearn 1976), and assume Mar Biodiv that at least one member of that genus was present.…”

Some Implications of High Biodiversity for Management of Tropical Marine Ecosystems—An Australian Perspective

“…While we have good data on increasing frequency of coral bleaching stress associated with increased water temperatures [47,48], there is little appreciation of the associated fauna of live coral that will become locally extinct when a coral colony dies [49][50][51]. Earlier, Holbrook [52] showed that coral dwelling fishes are very sensitive to loss of live coral and sedimentation and eutrophication arising from coastal development as they typically have small population sizes which makes them extremely vulnerable to extinction from human induced disturbances on reefs.…”
