Los octocorales son cnidarios bentónicos que tienen una importancia estructural y funcional en los arrecifes coralinos, y por ser sésiles, no pueden emigrar de los arrecifes eutrofizados, por lo que reflejan las condiciones ambientales que han existido durante su desarrollo. Este trabajo sintetiza las respuestas de los octocorales en el nivel de co...

Eutrophication is one of the causes of the degradation of reefs worldwide. The aim of this research is to determine if sewage discharge reaches the fore reefs at northwest of Cuba using δ15N in tissues of the octocorals Eunicea flexuosa and Plexaura kuekenthali and the concentration of microbiological and physical-chemical variables. Thirteen reefs...

A fundamental understanding of the impact of petrochemicals and other stressors on marine biodiversity is critical for effective management, restoration, recovery, and mitigation initiatives. As species-specific information on levels of petrochemical exposure and toxicological response are lacking for the majority of marine species, a trait-based a...

[English below] Cuando se hace referencia al cambio climático, el imaginario colectivo nos hace pensar en el derretimiento de los glaciares o en osos polares famélicos que están a la deriva en un vasto océano sobre un pedazo de hielo minúsculo. Difícilmente nos imaginamos las consecuencias de los problemas ambientales y cómo éstos afectan ya y segu...

Coral reef habitats surrounding cuba include relatively healthy, well-developed shallow and mesophotic (30-150 m) scleractinian communities at the cross-currents of the Tropical Western Atlantic (TWA). However, Cuba's coral communities are not immune to the declines observed throughout the TWA, and there is limited information available regarding g...

Hurricanes can cause extensive long-term damage to small-scale fisheries. Yet, information is scarce on how communities are locally impacted by extreme events in the Caribbean and in other parts of the world. Focusing on an artisanal fishery in Yaguajay, Sancti Spiritus, Cuba, this article explores how artisanal fishers have perceived and responded...

This dataset accompanies "Spatio temporal variation in oc- tocoral assemblages along a water quality gradient in the northwestern region of Cuba" [1] . Sampling units were quadrats of 1 m 2 (each 1 x 1 m), positioned by a random- systematic design at 10 m depth on the rocky-coral substrate. The number of colonies of octocoral species in thirteen fo...

Rivers are the main sources of nutrients to coastal zones. Therefore, the effects of water quality degradation on octocoral assemblages and their relationship with microbiological and physical-chemical variables were determined in reefs close to river basins in the northwestern region of Cuba. The evaluations were carried out in 1 m 2 frames at a d...

The importance of coral reefs (CR) within marine ecosystems has become widely recognized. Although shallow CR are not as abundant in the Gulf of Mexico (GoM) as in other areas such as the Caribbean, their uniqueness, singularity, isolation, and conservation status make their conservation highly important. Corals and CR, both shallow and deep, are m...

Scleractinian corals are bathed in a sea of planktonic and particle-associated microorganisms. The metabolic products of corals influence the growth and composition of microorganisms, but interactions between corals and seawater microorganisms are underexplored. We conducted a field-based survey to compare the biomass, diversity, composition, and f...
