Spatial distribution of settlement of Diadema antillarum around Saba, Dutch Caribbean [PDF]

PeerJ
The mass mortality event of the herbivorous sea urchin Diadema antillarum in 1983–1984 has been a major contributor to the diminished resilience of coral reefs throughout the Caribbean.

Spatial and seasonal variation of the gonad index of Diadema antillarum (Echinodermata:Echinoidea) in the Canary Islands [PDF]

Scientia Marina, 2006
Diadema antillarum Philippi occurs in high density populations in the Canary Islands, creating extensive barren areas. During one year we determined seasonal changes in the algal abundance and population densities, test diameter, gut contents ...

Impacts of hurricanes and disease on Diadema antillarum in shallow water reef and mangrove locations in St John, USVI. [PDF]

PLoS ONE
The 1983-1984 mortality event of the long-spined sea urchin Diadema antillarum reduced their population by up to 99% and was accompanied by a phase shift from coral dominated to algal dominated reefs in the Caribbean. Modest rebounds of D.

Genetic Features of the Scuticociliate Pathogen Philaster sp. Isolate FWC2 That Causes Sea Urchin Mass Mortality. [PDF]

J Eukaryot Microbiol
ABSTRACT A scuticociliate most closely related to Philaster apodigitiformis caused mass mortalities of diadematoid sea urchins and was cultured as Philaster sp. isolate FWC2. We sequenced the metagenomic content of this isolate, which was predicted to represent ≤ 56% of the complete genome.

Investigating the influence of Diadematidae scuticociliatosis on host microbiome composition [PDF]

mSystems
Mass mortality of Diadematidae urchins, caused by the Diadema antillarum scuticociliatosis Philaster clade (DScPc), affected the Caribbean in spring 2022 and subsequently spread to the eastern Mediterranean, Red Sea, and western Indian Ocean.

Grazing by Diadema antillarum (Philippi) upon algal communities on rocky substrates [PDF]

Scientia Marina, 2003
Grazing by Diadema antillarum sea urchins is well documented for coral reefs, although information is scarce for the eastern part of the Atlantic Ocean, where rocky substrate dominates the sea bottom. This study analysed grazing activity by D. antillarum

Half a century of echinoid population decline in the northern Gulf of Aqaba, Red Sea. [PDF]

J Anim Ecol
Multi‐decadal monitoring in the Gulf of Aqaba, northern Red Sea, reveals severe (>90%) declines of key echinoid grazers. These declines signify a collapse of crucial herbivory functions underpinning coral reef resilience. Results implicate accelerating anthropogenic stress as a principal driver, emphasizing the urgent need for sustained, species ...

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 ...
