Bahaman patch reefs: Numerous and neglected

The Depositional Record, EarlyView.
Abstract Phanerozoic patch reefs are extensively studied because they are abundant and are potential reservoirs for valuable fluids. In contrast, geologic studies of modern reefs have largely focused on platform margins, leaving patch reefs comparatively neglected. What conditions favour patch‐reef development?

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

Marine 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 ...

Visual information in the dark: Bioluminescence and perceptual design through evolution

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Bioluminescence offers a powerful framework for understanding how organisms evolve to shape visual information in diverse ways. Complementing studies of colour, transparency and pattern in illuminated environments, bioluminescent systems instead rely on generated light,

Chemical and biological aspects of octocorals from the Brazilian coast [PDF]

Revista Brasileira de Farmacognosia, 2014
AbstractThis review explores the chemical and biological aspects/results reported in the literature of the octocoral species collected at the Brazilian Coast. This article summarizes the biological activities (including pharmacological, antifouling and others related to chemical ecology) for the compounds and/or extracts described elsewhere.

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

Marine 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

Assessing the ecological and aesthetic effectiveness of restoration interventions on coralligenous reefs

Restoration Ecology, EarlyView.
Although tools for actively restoring marine habitats have advanced considerably, the capacity and timeframes for ecosystem recovery remain uncertain. Time and funding constraints, and lacking metrics to quantify the recovery process, represent the primary obstacles to evaluating restoration success.

Determinate Growth and Modularity in a Gorgonian Octocoral

The Biological Bulletin, 2003
Growth rates of branches of colonies of the gorgonian Pseudopterogorgia elisabethae were monitored for 2 years on a reef at San Salvador Island, Bahamas. Images of 261 colonies were made at 6-month intervals and colony and branch growth analyzed. Branch growth rates differed between colonies and between the time intervals in which the measurements were

Different processes and constraints drive the assembly of deep‐sea hydrothermal vent and sunken wood communities

Ecosphere, Volume 16, Issue 8, August 2025.
Abstract Niche processes mainly dictate the successful establishment and coexistence of species along gradients of community drivers such as energy availability and environmental stress. Deep‐sea chemosynthetic habitats such as hydrothermal vents and wood falls show concomitant gradients of energy availability and stress because productivity is fueled ...

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.
