Physiological and Epigenetic Responses of the Long‐Spined Sea Urchin Diadema antillarum Across a Spatiotemporal Gradient [PDF]

Ecology and Evolution
Following catastrophic population declines in the 1980s and 2022, the keystone herbivore Diadema antillarum has become a focal species for Caribbean‐wide restoration initiatives. In the present work, we combined an 11‐month field survey across four reefs

Factors constraining natural recovery of Diadema antillarum following a mass die-off: a case study near the island of Saba, Caribbean Netherlands [PDF]

PeerJ
After the mass mortality of 1983–1984, recovery of the keystone herbivore Diadema antillarum has been limited. Persistently low population densities reduced grazing pressure, leading to algal dominance on many Caribbean reefs.

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.

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.

Sargassum blooms in the Caribbean alter the trophic structure of the sea urchin Diadema antillarum [PDF]

PeerJ, 2019
The arrival of large masses of drifting Sargassum since 2011 has caused changes in the natural dynamics of Caribbean coastal ecosystems. In the summer of 2015, unprecedented and massive mats of S. fluitans and S.

Lack of recovery of the long-spined sea urchin Diadema antillarum Philippi in Puerto Rico 33 years after the Caribbean-wide mass mortality [PDF]

PeerJ, 2020
Caribbean populations of the long-spined black sea urchin Diadema antillarum Philippi were decimated by a disease-induced mass mortality in the early 1980’s. The present study provides an updated status of the D.

Tandem reef restoration using corals and sea urchins: Building complex habitat for herbivores. [PDF]

PLoS ONE
Amidst the decline of coral reef ecosystems, restoration practitioners are expanding their focus to incorporate key reef community components, such as grazers, to improve site conditions and the long-term survivorship of restored corals.

Seasonality shapes gut microbiota composition in two sympatric sea urchins [PDF]

PeerJ
Background The gut microbiota plays critical roles in digestion, immunity, and environmental adaptation in marine invertebrates. Its composition is shaped by both host traits and abiotic factors such as temperature and seasonality.

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.
