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.

Widespread but variable toxicity in scleractinian corals

Toxicon, 1990
Aqueous 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, 2004
AbstractTransportation 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, 2007
In 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, 2011
Viruses 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.

Hard Tissue Tumors of Scleractinian Corals

1975
The susceptibility of vertebrates to neoplasia is believed linked to the presence of an immunologic apparatus and a well-developed lymphoid system1. Recent observations on invertebrates have revealed the presence of primitive immunologic mechanisms, beginning with the coelenterates2.

Reassessing evolutionary relationships of scleractinian corals

Coral Reefs, 1996
The widely accepted family tree of Scleractinia published by Wells, based on a combination of morphological coral taxonomy and the fossil record, has recently been revised by Veron. It is now possible to test the validity of some of the conclusions reached by these and other authors by the use of molecular techniques.

Sexual Reproduction of Scleractinian Corals

2010
Sexual reproduction by scleractinian reef corals is important for maintaining coral populations and evolutionary processes. The ongoing global renaissance in coral reproduction research is providing a wealth of new information on this topic, and has almost doubled the global database on coral reproductive patterns during the past two decades ...
