Recovery dynamics of the Caribbean long-spined sea urchin, Diadema antillarum
2011The sea urchin Diadema antillarum is a keystone herbivore in the Caribbean and its functional extinction due to an epidemic in 1983 had a marked effect on coral reef health. Recovery of D. antillarum has been associated with improvements in reef health but has been unexpectedly slow and patchy with many populations persisting at low abundance on the ...

An external tagging technique for the long-spined sea urchin Diadema aff. antillarum
Journal of the Marine Biological Association of the United Kingdom, 2007An in situ tagging technique for the long-spined sea urchin Diadema aff. antillarum, suitable for carrying out short and medium term ecological studies is described. It is a simple method in which external nylon tags are anchored in holes drilled through the urchin test. The technique was tested in the field and found to be effective for individuals of

Postmetamorphic growth and metabolism measurements were obtained on two cohorts of laboratory-reared Diadema antillarum. The cohorts grew linearly from less than 1 mm to over 43 mm. Daily growth averaged 0.097 and 0.11 mm d−1, respectively, for the two cohorts, and was found to differ significantly.

The long-spined sea urchin Diadema africanum is a key herbivore in sublittoral ecosystems of the Eastern Atlantic, mediating shifts between productive macroalgae beds and barren grounds. Historical increases in D. africanum densities have been linked to predator overfishing and rising temperatures favoring settlement.

Caribbean populations of the long-spined sea urchin, Diadema antillarum (Philippi, 1845), have undergone two mass mortality events since the 1980s that have caused 93%–100% of individuals on any given reef to perish. Subsequently, coral recruitment and survival declined, in part due to algal overgrowth and an increase in secondary metabolites ...

In Tasmania, arrival of the long-spined sea urchin (Centrostephanus rodgersii) has presented economic opportunity along with ecological change where they occur. Over the last half century, C. rodgersii has undergone climate driven range-extension and is now distributed along the entire east coast of Tasmania. The highest densities of C. rodgersii occur

This study assessed shelter homing in the long-spined sea urchin Diadema africanum, a key herbivore in Macaronesian benthic ecosystems and a species associated with the formation of urchin barrens in the Canary Islands. Historical data collected in Gran Canaria in 2008 (n = 170) were compared with a recent survey conducted in 2026 (n = 168) at Risco ...
