The 1983-1984 die-off of the long-spined sea urchin Diadema antillarum stands out as a catastrophic marine event because of its detrimental effects on Caribbean coral reefs. Without the grazing activities of this key herbivore, turf and macroalgae became the dominant benthic group, inhibiting coral recruitment …

Diadema sea urchins (Diadema antillarum) are important algae grazers, but restoration attempts often record low survival of restocked individuals. This article sheds light on one of the causes for unsuccessful restocking. Restocked sea urchins were monitored with time-lapse cameras for 10 days. There …

The massive die-off of the sea urchin Diadema antillarum in 1983–1984 is one the main reasons for low coral recruitment and little coral recovery in the Caribbean. As the natural recovery of D. antillarum is slow to non-existent, multiple restoration studies have been attempted. There are currently three …

The massive die-off of the herbivorous sea urchin Diadema antillarum in 1983 and 1984 resulted in phase shifts on Caribbean coral reefs, where macroalgae replaced coral as the most dominant benthic group. Since then, D. antillarum recovery has been slow to non-existent on most reefs. Studying settlement …

In this research paper, it was concluded that there still remains a lot of uncertainty in the predicament of when a gas-trip can occur on dual-fuel propelled ships. In a situation on board of the Coral Energy, these gas-trips resulted in the main engine not being able to switch-over to gas-mode again. …

This literature review is written for those concerned with the protection of oceans, reefs and communities as well as anyone interested in it. The literature study focuses on answering the question ‘what are the consequences for coral reefs if corallivorous fish become extinct?’. Accelerated trends in …

Caribbean coral reefs are in decline and the deployment of artificial reefs, structures on the sea bottom that mimic one or more characteristics of a natural reef, is increasingly often considered to sustain ecosystem services. Independent of their specific purposes, it is essential that artificial reefs …

Diadema sea-urchins play a vital role in maintaining a balanced coral reef ecosystem by grazing away algae and creating bare substrate for coral recruitment. The RAAKPRO Diadema project aims to develop interventions to improve larval recruitment and juvenile survival to increase local Diadema populations. …

Coral reefs are of great importance for social, biological and economical purposes. However, due to global and local threats they are declining rapidly. One of the ways to sustain coral reefs is sexual coral propagation. While the sexual propagation of corals for reef rehabilitation has been successful …
