Abstract Mesophotic coral ecosystems (MCEs), occurring between 30 and 150 m depth, are increasingly recognized for their ecological importance, yet they remain underexplored, particularly in the southwestern Indian Ocean. During benthic surveys conducted at depths ranging from 15 to 75 m off northwestern Reunion Island, we documented a dense and ...

Responses to High Seawater Temperatures in Zooxanthellate Octocorals
Increases in Sea Surface Temperatures (SSTs) as a result of global warming have caused reef-building scleractinian corals to bleach worldwide, a result of the loss of obligate endosymbiotic zooxanthellae. Since the 1980's, bleaching severity and frequency has increased, in some cases causing mass mortality of corals.

Prey selectivity of the octocoral Carijoa riisei at Pernambuco, Brazil [PDF]
This study was designed to evaluate prey selection (type and size) by the octocoral Carijoa riisei at Porto de Galinhas beach, Northeast Brazil, relating prey availability in plankton with the content inside polyps. Diatoms and cyanophytes were the predominant items found in both polyp gastric cavity and plankton.

Shallow water coral reefs are the most diverse marine ecosystems, but there is an immense gap in knowledge when it comes to understanding the diversity of the vast majority of marine biota in these ecosystems.

Cladielloides A and B: New Eunicellin-Type Diterpenoids from an Indonesian Octocoral Cladiella sp.
Two new eunicellin-type diterpenoids, cladielloides A (1) and B (2), which were found to possess a 2-hydroxybutyroxy group in their structures, were isolated from an Indonesian octocoral identified as Cladiella sp.

Islands in the mud: The South Texas banks provide crucial mesophotic habitat for coral communities
On the continental shelf off the coast of South Texas lie a series of natural hard-bottom structures (rocky outcrops and relic coral-algal reefs) known as the South Texas Banks (STB), which provide critical habitat for benthic organisms and pelagic fish.

The microbiome of the boring giant clam, Tridacna crocea, varies among tissues, with Endozoicomonas dominating most tissues and putative carotenoid‐producing bacteria (Rubritalea, Muricauda) enriched in the outer mantle. Using dark‐induced bleaching, we examined the impact of symbiont loss on bacterial communities and found that the overall bacterial ...

Cytotoxic Amides from the Octocoral Telesto riisei [PDF]
Two new acyl derivatives of beta-phenylethylamine, N-(2-phenylethyl)-9- oxohexadecacarboxamide (1) and N-(2-phenylethyl)-9-hydroxyhexadecacarboxamide (2), and two new tetrahydroxysterols, cholestane-3 beta, 5 alpha,6 beta-26-tetrol 27-acetate (3) and cholestane-3 beta, 5 alpha, 6 beta-26-tetrol (4), have been isolated from the coelenterate Telesto ...

This study uses modeling techniques to predict the characteristics of deep‐water coral communities under climate scenarios. It reveals that climate change will drive shifts of many deep‐water corals to deeper waters, leading to major changes in biodiversity and ecosystem functions of deep‐water coral communities.

Fixing and Embedding Protocol for Octocorals and Their Sclerites [PDF]
Abstract Many organisms are mostly soft tissue, with hard bits embedded within them. This includes many invertebrates, and vertebrates with calcified areas in their tissues. This procedure works well for soft-bodied corals which have hard pieces of calcium carbonate (sclerites) embedded in their tissues.
