Evaluation of stony coral indicators for coral reef management

Marine Pollution Bulletin, 2008
Colonies of reef-building stony corals at 57 stations around St. Croix, US Virgin Islands were characterized by species, size and percentage of living tissue. Taxonomic, biological and physical indicators of coral condition were derived from these measurements and assessed for their response to gradients of human disturbance-a requirement for ...

Bioactive Polyacetylenes from Stony Corals

Chemistry Letters, 1990
Abstract Four new polyacetylenes have been isolated from three species of hermatypic corals, Montipora sp, M. mollis, and Pectinia lactuca. These compounds, representing the first such metabolites of coelenterates, exhibited ichthyotoxicity and inhibited the growth of some bacteria and fungi.

Reciprocal-transplantation between shallow and mesophotic stony corals

Marine Environmental Research, 2020
Most studies to date on the various life-history aspects of scleractinian corals (e.g. reproduction, connectivity, and physiology) have focused on their innate habitats. However, comprehensive data on the ability of both shallow and mesophotic corals to contend in the coming decades with the different environmental conditions they may encounter due to ...

Cytotoxic Diacetylenes from the Stony Coral Montipora Species

Journal of Natural Products, 2001
Ten new (1, 4-6, 9-14) and four known (2, 3, 7, 8) diacetylenes have been isolated from a brine shrimp active fraction of the methanolic extract of the stony coral Montipora sp. The structures were determined by combined spectroscopic methods. The compounds exhibited significant cytotoxicity against a small panel of human solid tumor cell lines ...

The digestive system of the stony coral Stylophora pistillata

Cell and Tissue Research, 2017
Because hermatypic species use symbiotic algal photosynthesis, most of the literature in this field focuses on this autotrophic mode and very little research has studied the morphology of the coral's digestive system or the digestion process of particulate food.

Stony Corals from Rocas Alijos

1996
Rocas Alijos lies approximately 343 km west of Baja California Sur, Mexico, at approximately 25°N latitude. During the 1990 Cordell Expedition to this site, two species of corals in two genera were collected by divers and forwarded to the author for examination.

Aplysinopsin Dimers from a Stony Coral. Tubastraea aurea

HETEROCYCLES, 2008
- Five novel bis(indole) alkaloids, which were composed of two molecules of aplysinopsin have been isolated from a stony coral, Tubastraea aurea. Their structures were elucidated on the basis of spectroscopic methods.

Stony coral diseases observed in southwestern Caribbean reefs

Hydrobiologia, 2001
Thirteen reef areas of Colombian territories in the Southwestern Caribbean were surveyed during the last 10 years. Coral diseases have been recorded in all these areas since 1990 and some of them have increased progressively. Six types were differentiated in the region, of which black band disease (BBD), dark spots disease (DSD), white band disease ...
