Investigating the photosynthesis of Symbiodinium in Caribbean gorgonian corals
… including scleractinian corals and octocorals. Studies examining the symbiosis between Caribbean octocorals and Symbiodinium are sparse, even though octocorals blanket the landscape of Caribbean coral reefs. Here, I compared the photosynthetic characteristics of Symbiodinium in four …

Marine Microbial Communities in Health and Disease: an Exploration of Marine Bacterial Associations Across Space, Time, and Potential Roles Against Pathogens in the Context of the Current Global Climate Change Scenario
… from being dominated by scleractinian corals to octocorals, sponges and/or macroalgae dominance. As Caribbean coral reefs have been indicated as a 'hot spot' for marine diseases, this dissertation primarily focused on providing insights into the putative roles of the microbial communities …

The Effect of Historic Shipwrecks on Sediment Microbiomes in the Northern Gulf of Mexico
… habitats including methane seeps, wood falls, octocoral, and deep-sea sediments. However, it was unknown if the presence of man-made structures on the seafloor, including historic shipwrecks, also resulted in a distinct core microbiome. To determine how historic shipwrecks impact sediment …

Octocorallia (Cnidaria: Anthozoa) da plataforma continental e ilhas oceânicas brasileiras: famílias Paramuriceidae e Plexauridae
Fourteen species of octocorals, from the Brazilian continental platform and oceanic islands, from depths between 20 and 400m, were studied regarding aspects of their taxonomy, bathymetry, and geographical distribution. These species included nine Paramuriceidae (Bebryce cinerea, Bebryce sp., …

The role of abiotic and biotic interactions in deep-sea benthic habitats of the northeastern Gulf of Cadiz
… found to decrease habitat suitability for large octocoral species while increasing the abundance of commercial species like the Norway lobster. The results suggested that bottom trawling causes significant reduction in the octocoral distribution, together with substrate homogenization, and …

South African marine compounds as anticancer agents
… aliwaliensis and the malonganenones from the octocoral Leptogorgia gi/christii. The identification of a number of novel, active compounds through our screening program highlights the potential of marine organisms from the southern African coast as a source of novel drug leads.

Synthetic studies towards total synthesis of bielschowskysin
… diterpene isolated from the Caribbean gorgonian octocoral Pseudopterogorgia kallos, possesses a fascinating tricyclic [5-4-9] ring architecture, unprecedented in the realms of natural products. This diterpene exhibits antiplasmodial activity against several drug-resistant strains of the …

Biochemical Composition of Caribbean Gorgonian Corals and Their Symbiosis Under Ambeint and Stressful Conditions
Gorgonian corals are the dominant benthic fauna on Caribbean reefs. Unlike scleractinian corals, gorgonian abundance on these reefs has remained stable or has increased. Therefore, to predict how climate change will affect the reef community, it is essential to understand gorgonian physiology under …
