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 ...

Skeletal Low-Magnesium Calcite in Living Scleractinian Corals

Science, 1975
The skeletons of living specimens of the scleractinian coral Porites lobata have been found to contain up to 46 ± 5 percent low-magnesium calcite even though free of gross detrital inclusions and boring or encrusting organisms.

Immunological specificity and memory in a scleractinian coral

Nature, 1977
Tissue transplantation immunity with a specific memory component is demonstrated in populations of Montipora. This highly discriminating immunoreactivity derives from extensive allogeneic polymorphism of histocompatibility (H) markers. An H system of immunorecognition is postulated to have originated in multicellular invertebrates probably beginning ...

A Cretaceous Scleractinian Coral with a Calcitic Skeleton

Science, 2007
It has been generally thought that scleractinian corals form purely aragonitic skeletons. We show that a well-preserved fossil coral, Coelosmilia sp. from the Upper Cretaceous (about 70 million years ago), has preserved skeletal structural features identical to those observed in present-day scleractinians.
