The Brazilian octocoral Phyllogorgia dilatata as a source of cytotoxic compounds

Anais da Academia Brasileira de Ciências, 2021
The extensive marine biodiversity has proved to be a promising source of substances with biomedical potential. In this study, the cytotoxicity of the Brazilian octocoral Phyllogorgia dilatata (Gorgoniidae) was evaluated against two tumor cell lines and ...

Diversity, host specificity and biogeography in the Cladocorynidae (Hydrozoa, Capitata), with description of a new genus

Cladistics, Volume 38, Issue 1, Page 13-37, February 2022., 2022
Abstract The hydrozoan family Cladocorynidae inhabits tropical to temperate waters and comprises the two genera Pteroclava and Cladocoryne. Pteroclava lives in association with some octocorals and hydrozoans, whereas Cladocoryne is more generalist in terms of substrate choice.

Transcriptional response of the calcification and stress response toolkits in an octocoral under heat and pH stress

Molecular Ecology, Volume 31, Issue 3, Page 798-810, February 2022., 2022
Abstract Up to one‐third of all described marine species inhabit coral reefs, but the future of these hyperdiverse ecosystems is insecure due to local and global threats, such as overfishing, eutrophication, ocean warming and acidification. Although these impacts are expected to have a net detrimental effect on reefs, it has been shown that some ...

Cellular responses in sea fan corals: granular amoebocytes react to pathogen and climate stressors. [PDF]

PLoS ONE, 2008
BACKGROUND: Climate warming is causing environmental change making both marine and terrestrial organisms, and even humans, more susceptible to emerging diseases. Coral reefs are among the most impacted ecosystems by climate stress, and immunity of corals,

Variable Growth Across Species and Life Stages in Caribbean Reef Octocorals

Frontiers in Marine Science, 2020
Growth rates often measured as linear extension rates can serve as a proxy for organismal performance across environments, yet few estimates of these growth rates exist, and fewer are reported from multi-year monitoring. We studied the effect of species,

A review of gorgonian coral species (Cnidaria, Octocorallia, Alcyonacea) held in the Santa Barbara Museum of Natural History research collection: focus on species from Scleraxonia, Holaxonia, and Calcaxonia – Part I: Introduction, species of Scleraxonia and Holaxonia (Family Acanthogorgiidae) [PDF]

ZooKeys, 2019
Gorgonian specimens collected from the California Bight (northeastern Pacific Ocean) and adjacent areas held in the collection of the Santa Barbara Museum of Natural History (SBMNH) were reviewed and evaluated for species identification; much of this ...

Total Synthesis of the Marine Diterpenoids Caucanolide E and F by Alkyne gem‐Hydrogenation: Rigorous Reassignment of Two Almost Indistinguishable Diastereomers

Angewandte Chemie, Volume 137, Issue 18, April 25, 2025.
The application of gem‐hydrogenation, which exploits the electrophilic character of the ruthenium carbene intermediates transiently formed, to natural product total synthesis allowed the stereostructure of a pair of diastereomeric seco‐cembranoids that are almost indistinguishable by NMR to be rigorously assigned.

Marine Natural Products Against Tuberculosis

The Scientific World Journal, Volume 6, Issue 1, Page 847-861, 2006., 2006
Natural products represent an outstanding source of compounds that play an important role in the treatment of human diseases. Due to the importance of nature as a source of new drug candidates, the aim of this review is to highlight the marine natural products, which exhibit antituberculosis activity, discovered between 2000 and 2005.

Dynamic Interplay of ENSO Events and Local Hydrodynamic Parameters Drives Demography and Health Status of Gorgonian Sea Fan Populations on a Remote Tropical Eastern Pacific Island

Frontiers in Marine Science, 2019
Gorgonian corals occurring in shallow waters are vulnerable to changing environmental conditions and human-related pressures such as pollution, overfishing, and diseases.

Associations of Commercial Fisheries and Cold‐Water Corals and Sponges

Fish and Fisheries, Volume 27, Issue 2, Page 116-129, March 2026.
Three metrics for determining whether the marine life that are landed by commercial fisheries are associated with cold‐water corals and sponges: (a) Adjacent; (b) General Proximity; and (c) Habitat. The relationship between these structure forming invertebrates (SFI) and fisheries is robust across analytical approaches.
