Ecological Factors Mediate Immunity and Parasitic Co-Infection in Sea Fan Octocorals

Frontiers in Immunology, 2021
The interplay among environment, demography, and host-parasite interactions is a challenging frontier. In the ocean, fundamental changes are occurring due to anthropogenic pressures, including increased disease outbreaks on coral reefs.

Dataset of octocoral assemblages in fore reefs in the northwestern region of Cuba

Data in Brief, 2020
This dataset accompanies ''Spatio temporal variation in octocoral assemblages along a water quality gradient in the northwestern region of Cuba'' [1]. Sampling units were quadrats of 1 m2 (each 1 x 1 m), positioned by a random-systematic design at 10 m ...

Phylogeography of Blue Corals (Genus Heliopora) Across the Indo-West Pacific

Frontiers in Marine Science, 2021
Species delimitation of corals is one of the most challenging issues in coral reef ecology and conservation. Morphology can obscure evolutionary relationships, and molecular datasets are consistently revealing greater within-species diversity than ...

Dissolved Nitrogen Acquisition in the Symbioses of Soft and Hard Corals With Symbiodiniaceae: A Key to Understanding Their Different Nutritional Strategies?

Frontiers in Microbiology, 2021
Nitrogen is one of the limiting nutrients for coral growth and primary productivity. Therefore, the capacity of different associations between corals and their algal symbionts (Symbiodiniaceae) to efficiently exploit the available nitrogen sources will ...

Polyoxygenated Steroids from the Octocoral Leptogorgia punicea and in Vitro Evaluation of Their Cytotoxic Activity

Marine Drugs, 2014
Five new polyoxygenated marine steroids—punicinols A–E (1–5)—were isolated from the gorgonian Leptogorgia punicea and characterized by spectroscopic methods (IR, MS, 1H, 13C and 2-D NMR). The five compounds induced in vitro cytotoxic effects against lung

Unlocking the Potential of Octocoral-Derived Secondary Metabolites against Neutrophilic Inflammatory Response

Marine Drugs, 2023
Inflammation is a critical defense mechanism that is utilized by the body to protect itself against pathogens and other noxious invaders. However, if the inflammatory response becomes exaggerated or uncontrollable, its original protective role is not ...
