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 oktober 2021 zijn op Saba met succes de allereerste Diadema-zee-egels op locatie gekweekt in het Caribisch gebied. De zee-egels helpen koraalriffen door de algen te eten die het koraal overwoekeren. Hiermee hebben onderzoekers van Hogeschool Van Hall Larenstein weer een belangrijke stap gezet voor …

On October 22st, 2021, the first ever recorded Diadema sea urchins in the Caribbean were cultured on Saba. Diadema sea urchins are important grazers and can facilitate corals by reducing their competition with algae. By culturing them, researchers from University of Applied Sciences Van Hall Larenstein …

University of Applied Sciences Van Hall Larenstein and Wageningen University and Research recently conducted a comparative study of artificial reefs within the Caribbean. This study provides new insights into the impacts of these structures on local marine life and neighboring ecosystems and highlight …

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 …

Bij hogeschool Van Hall Larenstein in Leeuwarden is de zee-egel Diadema antillarum gekweekt. Deze algeneter is belangrijk voor herstel van de koraalriffen rond Saba en Sint Eustatius (Caribisch Nederland). De eerste gekweekte jonge dieren zijn afgelopen week in Diergaarde Blijdorp in Rotterdam uitgezet. …

The sea urchin Diadema antillarum has been cultivated at Van Hall Larenstein University of Applied Sciences HVHL in Leeuwarden in the Netherlands to help restore the coral reefs around Saba and St. Eustatius.

Zee-egels uit laboratorium Van Hall Larenstein overgebracht naar Diergaarde Blijdorp. Interview met Tom Wijers, onderzoeker aan hogeschool Van Hall Larenstein.
