The Sea Urchin Diadema antillarum (Echinodermata, Equinoidea), algal cover and juvenile coral densities in La Parguera, Puerto Rico

Cuadernos de investigación UNED, 2013
Grazing by the black sea urchin Diadema antillarum reduces algal cover and enhances coral recruitment. The overall goal of this project was to examine if there is a relationship between densities of D.

Growth and foraging behavior of hatchery propagated long-spined sea urchins, Diadema antillarum: Implications for aquaculture and restocking

Aquaculture Reports, 2022
Stocking hatchery propagated long-spined sea urchins Diadema antillarum is a priority option for recovery of this keystone herbivore on Caribbean reefs. However, information on captive culture of D.

Abundance, distribution and size structure of Diadema antillarum (Echinodermata: Diadematidae) in South Eastern Cuban coral reefs

Revista de Biología Tropical, 2010
The 1983-1984 mass mortality event of Diadema antillarum affected more than 93% of the total Caribbean population. Although there are no records about the status of Diadema populations before and after die-off on Cuban reefs, anecdotal information ...

Assisted Natural Recovery: A Novel Approach to Enhance Diadema antillarum Recruitment

Frontiers in Marine Science, 2022
The massive die-off of the sea urchin Diadema antillarum in 1983–1984 is one the main reasons for low coral recruitment and little coral recovery in the Caribbean. As the natural recovery of D.

Biomarkers of recovery: Characterizing trophic flow following ecological restoration

Journal of Applied Ecology, Volume 63, Issue 4, April 2026.
Fatty acid biomarkers offer a scalable tool for detecting early trophic recovery, identifying high‐leverage depth strata for intervention, and evaluating whether restoration actions are rebuilding the ecosystem functions and fisheries‐relevant nutritional pathways that support resilient kelp forest ecosystems.

The 2022 Diadema antillarum die-off event: Comparisons with the 1983-1984 mass mortality

Frontiers in Marine Science, 2023
The 1983-1984 die-off of the long-spined sea urchin Diadema antillarum stands out as a catastrophic marine event because of its detrimental effects on Caribbean coral reefs. Without the grazing activities of this key herbivore, turf and macroalgae became
