Regeneration of artificially induced lesions was monitored in nubbins of the branching coral Acropora muricata at two reef-flat sites representing contrasting environments at Réunion Island (21°07'S, 55°32'E). Growth of these injured nubbins was examined in parallel, and compared to controls. Biochemical compositions of the holobiont and the zooxanthellae density were determined at the onset of...

Climate-induced disturbances are contributing to rapid, global-scale changes in coral reef ecology. As a consequence, reef carbonate budgets are declining, threatening reef growth potential and thus capacity to track rising sea-levels. Whether disturbed reefs can recover their growth potential and how rapidly, are thus critical research questions. Here we address these questions by measuring th...

Although knowledge on the diseases affecting corals has been accumulating exponentially since 2000s, even more effort is required to summarize and guide further investigation. Here, we used Web of Science database review 226 studies published, between 2000 2020, identify major geographic taxonomic gaps in literature, propose future directions for study coral diseases. We classified according oc...

Modern scleractinian coral skeletons are commonly composed of aragonite, the orthorhombic form of CaCO3. Under certain conditions, modern corals produce calcite as a secondary precipitate to fill pore space. However, coral construction of primary skeletons from calcite has yet to be demonstrated. We report a calcitic primary skeleton produced by the modern scleractinian coral Acropora tenuis. W...

Mining for microsatellites (also called simple sequence repeats [SSRs]) in public sequence databases of a common Indo-Pacific coral Acropora millepora identified 191 SSRs from 10 258 expressed sequence tag (EST) and 618 SSRs from 14 625 whole-genome shotgun (WGS) sequences. In contrast to other animals, trinucleotide repeats, rather than dinucleotide repeats, are dominant in the WGS-SSRs, and A...

Population outbreaks of crown-of-thorns sea star (Acanthaster planci L.) remain one of the most significant biological disturbances on tropical coral reefs although the increasing attention given to other threats has greatly limited recent progress in understanding the cause and consequences of this phenomenon. In September 2005 dramatic increases in the abundance of A. planci were observed on ...
