The first complete mitochondrial genome of Diadema antillarum (Diadematoida, Diadematidae) [PDF]

GigaByte, 2022
The mitochondrial genome of the long-spined black sea urchin, Diadema antillarum, was sequenced using Illumina next-generation sequencing technology. The complete mitogenome is 15,708 bp in length, containing two rRNA, 22 tRNA and 13 protein-

Shifts in the gut microbiota of sea urchin Diadema antillarum associated with the 2022 disease outbreak [PDF]

Frontiers in Microbiology
IntroductionIn recent decades, Caribbean coral reefs have lost many vital marine species due to diseases. The well-documented mass mortality event of the long-spined black sea urchin Diadema antillarum in the early 1980s stands out among these collapses.

A novel system for intensive Diadema antillarum propagation as a step towards population enhancement [PDF]

Scientific Reports, 2021
The long-spined sea urchin Diadema antillarum was once an abundant reef grazing herbivore throughout the Caribbean. During the early 1980s, D. antillarum populations were reduced by > 93% due to an undescribed disease.

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.

Comparison of feeding preferences of herbivorous fishes and the sea urchin Diadema antillarum in Little Cayman [PDF]

PeerJ, 2023
On Caribbean coral reefs, losses of two key groups of grazers, herbivorous fishes and Diadema antillarum, coincided with dramatic increases in macroalgae, which have contributed to decreases in the resilience of these coral reefs and continued low coral ...

A scuticociliate causes mass mortality of Diadema antillarum in the Caribbean Sea. [PDF]

Sci Adv, 2023
Echinoderm mass mortality events shape marine ecosystems by altering the dynamics among major benthic groups. The sea urchin Diadema antillarum , virtually extirpated in the Caribbean in the early 1980s by an unknown cause, recently experienced another mass mortality beginning in January 2022.

Diurnal predators of restocked lab-reared and wild Diadema antillarum near artificial reefs in Saba [PDF]

PeerJ, 2023
The long-spined sea urchin Diadema antillarum controls reef dynamics by grazing on algae and increasing coral recruitment. Populations of Diadema never recovered after a mass-die off in 1983 and 1984, and numbers were further reduced by a more recent die-

The ecological importance of habitat complexity to the Caribbean coral reef herbivore Diadema antillarum: three lines of evidence [PDF]

Scientific Reports, 2021
When Caribbean long-spined sea urchins, Diadema antillarum, are stable at high population densities, their grazing facilitates scleractinian coral dominance.

Viral metagenomic investigation of two Caribbean echinoderms, Diadema antillarum (Echinoidea) and Holothuria floridana (Holothuria) [PDF]

PeerJ
Background Echinoderms play crucial roles in coral reef ecosystems, where they are significant detritivores and herbivores. The phylum is widely known for its boom and bust cycles, driven by food availability, predation pressure and mass mortalities ...

Uneven demographic consequences of the 2022 disease outbreak for the sea urchin Diadema antillarum in Puerto Rico [PDF]

PeerJ, 2023
Pervasive epizootic events have had a significant impact on marine invertebrates throughout the Caribbean, leading to severe population declines and consequential ecological implications.
