Bioactivity of a polyhydroxy gorgostane steroid from Xenia umbellata

open access: yesOpen Chemistry, 2022
A C-30 steroid, 3β-,5α-,6β-,11α-,20β-pentahydroxygorgosterol was isolated from the soft coral Xenia umbellata Lamarck (Xeniidae). The chemical structure was elucidated by examining the NMR spectral data and comparison with the previously published data ...

Spatial and Short-Term Temporal Patterns of Octocoral Assemblages in the West Philippine Sea

open access: yesFrontiers in Marine Science, 2022
Octocorals are relatively understudied than other coral reef organisms despite their ecological and economic values. The Philippines is known to have high marine biodiversity, but information on octocorals is lacking.

Cytotoxic ketosteroids from the Red Sea soft coral Dendronephthya sp.

open access: yesOpen Chemistry, 2023
A marine specimen of the Red Sea soft coral Dendronephthya sp. was extracted with a mixture of n-hexane, diethyl ether, and methanol. One new cytotoxic steroid dendronestadione (1), five known steroids: dendronesterones A-C (2–4), dendrotriol (5), and ...

Species Delimitation of Hexacorallia and Octocorallia Around Iceland Using Nuclear and Mitochondrial DNA and Proteome Fingerprinting

open access: yesFrontiers in Marine Science, 2022
Cold-water corals build up reef structures or coral gardens and play an important role for many organisms in the deep sea. Climate change, deep-sea mining, and bottom trawling are severely compromising these ecosystems, making it all the more important ...

Supplementary data for: McFadden et al., Revisionary systematics of Octocorallia (Cnidaria: Anthozoa) guided by phylogenomics [PDF]

open access: yes, 2022
The anthozoan sub-class Octocorallia includes over 3500 nominal species of soft corals and gorgonian sea fans, many of which serve as critical foundation species in benthic marine ecosystems in shallow waters to the deep sea. Despite their familarity and

Genomic Resources for Imperiled Caribbean Reef-Forming Corals (Hexacorallia: Scleractinia): Complete Mitochondrial Genomes of <i>Dichocoenia stokesii</i>, <i>Diploria labyrinthiformis</i>, <i>Oculina patagonica</i>, and <i>Stephanocoenia intersepta</i>. [PDF]

open access: yesEcol Evol
Mitochondrial genomes of imperiled Caribbean corals are sequenced. These genomic resources will support conservation initiatives. ABSTRACT Coral reefs provide a wide variety of services essential to both marine ecosystems and human societies yet reef‐forming corals are currently facing a multitude of global and local environmental stressors.

Biogeographic patterns in sea pens (Octocorallia: Pennatulacea)

open access: yesMarine Biodiversity, 2023
AbstractPennatulaceans (Octocorallia: Pennatulacea) are among the most dominant octocoral species living in soft bottom communities. Some of them are cosmopolitan and have been recorded in all seas and oceans of the world, from shallow waters up to about 6260 m deep.
