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 …

Sinds de massasterfte van de belangrijke zee-egel soort Diadema Antillarum in het begin van de jaren 1980 zijn de koraalriffen in het Caribisch gebied sterk achteruit gegaan in productiviteit en biodiversiteit. Meerdere pogingen zijn gedaan om de populaties te herstellen, veelal met wisselend succes. …

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 …

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 …

De HBO opleidingen presenteren zich steeds nadrukkelijker als centra voor toegepast onderzoek, naast hun traditionele rol als onderwijsinstelling. Bij Van Hall Larenstein te Leeuwarden, binnen de opleiding Kust- en Zeemanagement, wordt baanbrekend onderzoek gedaan naar mogelijkheden om de koraalriffen …

Scleractinische koralen met endosymbiotisch Symbiodinium zijn de dominante soort van tropische koraalriffen. Deze koraalriffen vormen de habitat voor ongeveer 25% van de mariene soorten op Aarde. Ook voor de mens zijn koraalriffen van groot belang voor voedsel, toerisme en voor de economie. De laatste …

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 …

The invasive lionfish (Pterois volitans and Pterois miles) started invading the Caribbean Sea since the 1980’s and were first sighted on the Saba Bank since 2009 where they established themselves fully during the following two years. They have no specific preference for prey species and their predation …
