Unravelling echinoid mass mortalities: a global overview of mechanisms, spatio-temporal trends, and taxonomic insights. [PDF]
Biol Rev Camb Philos SocABSTRACT Mass mortality events (MMEs) have been occurring since the dawn of time. However, in contrast to terrestrial events, most marine MMEs remain undetected, largely due to the inaccessibility of many marine environments. One of the most notorious and best‐studied marine MMEs in modern times is that of the population collapse of the echinoid ...

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.

A novel technique for tagging the long-spined sea urchin Diadema antillarum [PDF]
Sarsia, 2003 We describe a new protocol for tagging the long‐spined sea urchin Diadema antillarum to study the daily activity patterns of this echinoid. The technique consists of the in situ introduction of a fishing hook into the periproctal membrane of individual D.

Demographic history of Diadema antillarum, a keystone herbivore on Caribbean reefs. [PDF]
Proc Biol Sci, 2001 The sea urchin Diadema antillarum was the most important herbivore on Caribbean reefs until 1983, when mass mortality reduced its populations by more than 97%.

Testing sea urchin and green sea turtle consumption of the allelopathic macroalga Galaxaura divaricata. [PDF]
Ecol EvolThis study investigates the feeding preferences of sea urchins and green sea turtles for the coral‐damaging macroalga Galaxaura divaricata. Results indicate that while sea urchins consume both G. divaricata and a preferred nonallelopathic alga, their consumption rates are significantly lower for G. divaricata.

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.

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