Two new marine-derived caryophyllene-type sesquiterpenoids, rumphellols A and B (1 and 2), were obtained from the gorgonian coral, Rumphella antipathies, collected off the waters of Taiwan. Although caryophyllene-type sesquiterpenes are rarely found in marine organisms, compounds of this type could be principal components of R. antipathies. The structures of new Compounds 1 and 2 were determined by analysis of their spectroscopic data, including 1D and 2D NMR experiments. Caryophyllene 1 and 2 were evaluated in terms of their anti-inflammatory activity by examining their inhibitory effects on the generation of superoxide anions and the release of elastase by human neutrophils.

Interplay of elasticity and flow velocity on gorgonian feeding and implications for bioinspired design.

Evidence shows that gorgonians are more resistant to ocean acidification and rising temperatures than hard corals and are vital to reef health and the reestablishment of disrupted coral reef communities. Gorgonian coral's resilience and its diversity of morphology and environment make it well-suited as a model organism for bioinspired design applied to particle capture. We focus on flow near the polyps, using an updated form of the immersed boundary method to model the fluid-structure interaction of the flexible polyps and the surrounding ocean water.

Article Synopsis
- Extreme climatic events (ECEs) like marine heatwaves pose serious threats to biodiversity, highlighting the need for understanding ecological responses to these recurring events.
- Researchers used a "multiple events" approach to study the effects of recurrent ECEs on the temperate coral Paramuricea clavata, assessing factors like environmental, genetic, and phenotypic influences over three years.
- Findings indicated that environmental impacts were the primary drivers of coral responses, with limited evidence of genetic adaptability, suggesting that P. clavata populations face significant challenges due to ongoing heat stress and may struggle to recover.

Global warming and heavy metals have become the major threat to the growth and reproduction of corals. However, unlike scleractinian corals, in the context of widespread coral degradation worldwide, there are few reports on the response of octocorallia corals to high-temperature stress and heavy metals. In the present study, we conducted indoor simulation experiments using Junceella squamata.

Microplastics, a new type of pollutants found in coral reefs, have attracted increasing attention. However, most of the current research focuses on the scleractinian corals and few reports on Octocorallia. To reveal the impact of microplastic exposure on Octocorallia, we analyzed the transcriptional response of the coral hosts Junceella squamata along with changes to the diversity and community structure of its symbiotic bacteria following exposure to polystyrene microplastics.

Mediterranean gorgonians are being threatened by the impact of recurrent extreme climatic events, such as marine heatwaves (MHWs). The white gorgonian Eunicella singularis was suggested to be the most resistant gorgonian species in the NW Mediterranean, mainly due to the presence of symbiotic algae. However, a substantial shift in the conservation condition of the species has been observed in the recent years.
