Ecography, Volume 2023, Issue 1, January 2023., 2023 Marine reserves are being established worldwide to conserve and manage marine resources, and are also often assumed to conserve the evolutionary potential of marine populations. However, comparisons of genomic patterns inside and outside marine reserves in multiple species are scarce.

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

Coral reef erosion: In situ measurement on different dead coral substrates on a Caribbean reef
Limnology and Oceanography, Volume 67, Issue 12, Page 2734-2749, December 2022., 2022 Abstract Widespread mortality of reef‐building coral substantially reduces the capacity for reef growth and makes available extensive bare substrate areas that in the absence of coral recovery will be eroded by a variety of external and internal bioeroders.

Global Ecology and Conservation, 2021 The Diadema antillarum population in the Florida Keys has not recovered since the Caribbean-wide mass mortality event of the early 1980s. Concomitantly, coral reefs have degraded to the point that there has been a loss of habitat complexity and thus of ...

Taxa-dependent temporal trends in the abundance and size of sea urchins in subtropical eastern Australia. [PDF]
Ecol EvolWe investigated the population dynamics of sea urchins on coral‐associated subtropical reefs at 7 sites in eastern Australia (28.196° S to 30.95° S) over 9 years (2010–2019), a period impacted by warming and heatwaves. Counter to expectation, biogeographic affinity did not explain shifts in species abundances in this region.

[Abundance of Diadema antillarum (Echinodermata: Echinoidea) in the coasts of Venezuela].
Revista de biologia tropical, 2006 Diadema antillarum is a shallow-water sea-urchin from the tropical Atlantic whose populations almost disappeared in 1983-84 because of widespread mortalities which reached 87-100 %. In Venezuela, urchin population densities before the mortality event were comparable to those of other Caribbean regions; however, later abundancies remain unknown.

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 ...

The Occurrence of Melanin in the Sea-Urchin, Diadema Antillarum Philippi
Journal of Investigative Dermatology, 1952 INTRODUCTION The characteristic dark color of Diadema antillarum is chiefly attributable to a black pigment, most of which is contained in large epidermal chromatophores (see Fig. 1). A red pigment is also present, but is easily separable from the black, being readily soluble in ethanol and acetone, whereas the black is not.
