Reef-building corals often possess high levels of intraindividual and intraspecific ribosomal DNA (rDNA) variation that is largely polyphyletic between closely related species. Polyphyletic rDNA phylogenies coupled with high intraindividual rDNA variation have been taken as evidence of introgressive hybridization in corals. Interpreting the data is problematic because the rDNA cluster evolves i...

Cyclone Yasi, one of the most severe tropical storms on record, crossed the central Great Barrier Reef (GBR) in February 2011, bringing wind speeds of up to 285 km hr⁻¹ and wave heights of at least 10 m, and causing massive destruction to exposed reefs in the Palm Island Group. Following the cyclone, mean (± S.E.) hard coral cover ranged from just 2.1 (0.2) % to 5.3 (0.4) % on exposed reefs and...

Biogeological dynamics consist of a combination of community-ecological responses based on individual-species physiological tolerance limits to a dominant environmental stressor and their consequences on carbonate sedimentological properties. This interplay was investigated in coral carpet systems (biostromal coral frameworks) in the southern Arabian Gulf in Abu Dhabi and Dubai (UAE). Five cora...

Coral reefs ae onne of the ecosystems who have both ecological and economical function. I Gunung Malang community, coral reef been used as main mateerial in lime powder production. The aim this research to identified species, distribution capacity production than how marketing system product. This conducted from January September 2018. data was collected by measurement identificatio ad then int...

Among various potential consequences of rarity is genetic erosion. Neutral genetic theory predicts that rare species will have lower genetic diversity than common species. To examine the association between genetic diversity and rarity, variation at eight DNA microsatellite markers was documented for 14 Acropora species that display different patterns of distribution and abundance in the Indo-P...

The distribution of corals in Japan covers a wide range of latitudes, encompassing tropical to temperate zones. However, coral communities in temperate zones contain only a small subset of species. Among the parameters that determine the distribution of corals, temperature plays an important role. We tested the resilience to cold stress of three coral species belonging to the genus Acropora in ...

The complex symbiotic relationship between corals and their dinoflagellate partner Symbiodinium is believed to be sustained through close associations with mutualistic bacterial communities, though little is known about coral associations with bacterial groups able to fix nitrogen (diazotrophs). In this study, we investigated the diversity of diazotrophic bacterial communities associated with t...

Abstract Molecular phylogenetics has fundamentally altered our understanding of the taxonomy, systematics and biogeography corals. Recently developed phylogenomic techniques have started to resolve species-level relationships in diverse ecologically important genus Acropora, providing a path taxonomy this notoriously problematic group. We used targeted capture dataset (2032 loci) investigate sy...

The species composition of coral communities has shifted in many areas worldwide through the relative loss of important ecosystem engineers such as highly branched corals, which are integral in maintaining reef biodiversity. We assessed the degree to which the performance of recently recruited branching corals was influenced by corallivory, competition, sedimentation, and the interactions betwe...

BACKGROUND Climate-induced coral bleaching poses a major threat to coral reef ecosystems, mostly because of the sensitivities of key habitat-forming corals to increasing temperature. However, susceptibility to bleaching varies greatly among coral genera and there are likely to be major changes in the relative abundance of different corals, even if the wholesale loss of corals does not occur for...
