  abstract = {{B}iogenic dissolution of carbonates by microborers is one of the main destructive forces in coral reefs and is predicted to be enhanced by eutrophication and ocean acidification by 2100. {T}he chlorophyte {O}streobium sp., the main agent of this process, has been reported to be one of the most responsive of all microboring species to those environmental factors. {H}owever, very little is known about its recruitment, how it develops over successions of microboring communities, and how that influences rates of biogenic dissolution. {T}hus, an experiment with dead coral blocks exposed to colonization by microborers was carried out on a reef in {N}ew {C}aledonia over a year period. {E}ach month, a few blocks were collected to study microboring communities and the associated rates of biogenic dissolution. {O}ur results showed a drastic shift in community species composition between the 4th and 5th months of exposure, i.e., pioneer communities dominated by large chlorophytes such as {P}haeophila sp. were replaced by mature communities dominated by {O}streobium sp. {P}rior the 4th month of exposure, large chlorophytes were responsible for low rates of biogenic dissolution while during the community shift, rates increased exponentially (x10). {A}fter 6 months of exposure, rates slowed down and reached a "plateau" with a mean of 0.93 kg of {C}a{CO}3 dissolved per m(2) of reef after 12 months of exposure. {H}ere, we show that (a) {O}streobium sp. settled down in new dead substrates as soon as the 3rd month of exposure but dominated communities only after 5 months of exposure and (b) microbioerosion dynamics comprise three distinct steps which fully depend on community development stage and grazing pressure.},
