Phylogeography of Blue Corals (Genus Heliopora) Across the Indo-West Pacific

open access: yesFrontiers in Marine Science, 2021
Species delimitation of corals is one of the most challenging issues in coral reef ecology and conservation. Morphology can obscure evolutionary relationships, and molecular datasets are consistently revealing greater within-species diversity than ...

A case of modular phenotypic plasticity in the depth gradient for the gorgonian coral Antillogorgia bipinnata (Cnidaria: Octocorallia) [PDF]

open access: yes, 2017
Background: Phenotypic plasticity, as a phenotypic response induced by the environment, has been proposed as a key factor in the evolutionary history of corals. A significant number of octocoral species show high phenotypic variation, exhibiting a strong

Fuzzy species limits in Mediterranean gorgonians (Cnidaria, Octocorallia): inferences on speciation processes [PDF]

open access: yes, 2017
The study of the interplay between speciation and hybridization is of primary importance in evolutionary biology. Octocorals are ecologically important species whose shallow phylogenetic relationships often remain to be studied. In the Mediterranean Sea,

Briarane Diterpenoids Isolated from Octocorals between 2014 and 2016

open access: yesMarine Drugs, 2017
The structures, names, bioactivities, and references of 124 briarane-type natural products, including 66 new metabolites, isolated between 2014 and 2016 are summarized in this review article. All of the briarane diterpenoids mentioned in this review were

Climate Change Leads to a Reduction in Symbiotic Derived Cnidarian Biodiversity on Coral Reefs

open access: yesFrontiers in Ecology and Evolution, 2021
Symbiotic relationships enable partners to thrive and survive in habitats where they would either not be as successful, or potentially not exist, without the symbiosis.

Excavatoids E and F: Discovery of Two New Briaranes from the Cultured Octocoral Briareum excavatum

open access: yesMarine Drugs, 2009
Two new briarane-related diterpenoids, designated as excavatoids E (1) andF (2), were isolated from the cultured octocoral Briareum excavatum. The structures ofcompounds 1 and 2 were established on the basis of extensive spectral data analysis. Briaranes

Habitat connectivity in reef fish communities and marine reserve design in Old Providence-Santa Catalina, Colombia [PDF]

open access: yes, 2003
On the insular platform of Old Providence/Santa Catalina, Colombia, we compared nearshore lagoonal patch reefs to those on the northern bank distant from the islands to determine the importance of habitat connectivity to fish community structure ...

Briareolate Esters from the Gorgonian <em>Briareum asbestinum</em>

open access: yesMarine Drugs, 2012
Two new briarane diterpenoids briareolate esters J (<strong>1</strong>) and K (<strong>2</strong>) were isolated from the methanolic extract of the octocoral <em>Briareum</em><em> asbestinum </em>collected ...

Early Life-History Dynamics of Caribbean Octocorals: The Critical Role of Larval Supply and Partial Mortality

open access: yesFrontiers in Marine Science, 2021
Recruitment is a key demographic process for maintenance of local populations and recovery following disturbance. For marine invertebrates, distribution and abundances of recruits are impacted by spatiotemporal variation in larval supply, settlement ...

Polyoxygenated Steroids from the Octocoral Leptogorgia punicea and in Vitro Evaluation of Their Cytotoxic Activity

open access: yesMarine Drugs, 2014
Five new polyoxygenated marine steroids—punicinols A–E (1–5)—were isolated from the gorgonian Leptogorgia punicea and characterized by spectroscopic methods (IR, MS, 1H, 13C and 2-D NMR). The five compounds induced in vitro cytotoxic effects against lung
