Bioactivity of Scleractinian corals

Toxicon, 2015
Three hundred and four scleractinian colonies representing 58 species and 11 families were collected from six intertidal sites at Heron Island Reef, Great Barrier Reef. Tissue obtained from each colony was extracted with water, aqueous ethanol or a methanol-dichloromethane mixture.

Hierarchically structured scleractinian coral biocrystals

Journal of Structural Biology, 2008
Microscopic (AFM and FESEM) observations show that scleractinian coral biomineral fibers in extant Desmophyllum and Favia, and fossil Jurassic Isastrea are composed of nanocrystalline grains of about 30-100 nm in size. In contrast to these findings, SR diffraction data on the same coral materials exhibit narrow Bragg peaks suggesting much larger ...

Heterotrophy in Tropical Scleractinian Corals

Biological Reviews, 2009
AbstractThe dual character of corals, that they are both auto‐ and heterotrophs, was recognized early in the twentieth Century. It is generally accepted that the symbiotic association between corals and their endosymbiotic algae (called zooxanthellae) is fundamental to the development of coral reefs in oligotrophic tropical oceans because zooxanthellae

Hormones and reproduction in scleractinian corals

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2006
Most broadcast spawning scleractinian corals synchronously release gametes during a brief annual spawning period. In southern Taiwan, the mass spawning of scleractinians occurs in lunar mid-March. The exact cues triggering this annual phenomenon remain unclear.

Microplastic ingestion by scleractinian corals

Marine Biology, 2015
We report for the first time the ingestion of microplastics by scleractinian corals, and the presence of microplastics in coral reef waters adjacent to inshore reefs on Australia’s Great Barrier Reef (GRE, 18°31′S 146°23′E). Analysis of samples from sub-surface plankton tows conducted in close proximity to inshore reefs on the central GBR revealed ...

Morphological plasticity in scleractinian corals

Biological Reviews, 2008
AbstractWhen describing coral shape and form the term phenotypic plasticity, i.e. environment‐induced changes in morphology, is often used synonymously with intraspecific variation. Variation, however, may simply be due to genetic differentiation (polymorphism).

Sexual Reproduction of Mediterranean Scleractinian Corals

2016
The reproduction of scleractinian corals is a fundamental process for maintaining their populations and is essential for understanding the corals’ ecology. However, it has been described in less than 30 % of known species. The majority of these studies were carried out in the tropics.

Uranium in scleractinian coral skeletons

Coral Reefs, 1982
Accurate determinations have been made of the distribution of uranium in fresh and diagenetically altered coral skeletons occurring both naturally and grown under a variety of experimental conditions. Whereas live coral skeletons are homogeneous in uranium distribution, dead skeletons show heterogeneities relating to lithothamnioid algal encrustations ...

Skeletal ontogeny in basal scleractinian micrabaciid corals

Journal of Morphology, 2012
AbstractThe skeletal ontogeny of the Micrabaciidae, one of two modern basal scleractinian lineages, is herein reconstructed based on serial micro‐computed tomography sections and scanning electron micrographs. Similar to other scleractinians, skeletal growth of micrabaciids starts from the simultaneous formation of six primary septa.
