Hormones and reproduction in scleractinian corals
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2006Most 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, 2015We 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, 2008AbstractWhen 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
2016The 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, 1982Accurate 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, 2012AbstractThe 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.

Widespread but variable toxicity in scleractinian corals
Toxicon, 1990Aqueous and/or aqueous ethanol extracts were made of 58 scleractinian species from 11 families, collected from Heron Island, Great Barrier Reef. At least one extract from each of 53 species (91%) exhibited activity against at least one bioassay system.

Transportation techniques for massive scleractinian corals
Zoo Biology, 2004AbstractTransportation techniques for scleractinian corals have been described mainly for fragments and small colonies. As part of a recent study on captive sexual reproduction of the Caribbean species Montastrea annularis and Diploria strigosa, we transported relatively large (max. diameter of 21 cm), heavy (max.

Ocean Acidification and Scleractinian Corals
Science, 2007In their Brevia “Scleractinian coral species survive and recover from decalcification” (30 March, p. [1811][1]), M. Fine and D. Tchernov present an exciting experimental approach documenting how coral skeletons dissolve as a physiological response to increased atmospheric CO2, a ...

Viruses of reef-building scleractinian corals
Journal of Experimental Marine Biology and Ecology, 2011Viruses are ubiquitous and abundant pathogens that likely infect and disrupt all cellular organisms. Although a high diversity of viral types has been characterized from corals over the last decade, we are only beginning to understand the distribution, dynamics, and roles of viral consortia in reef ecosystems.
