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. …

Een nieuwe studie vergeleek de effectiviteit van drie populaire kunstmatige riffen om de visdichtheid rond Saba en Sint Eustatius te vergroten. De onderzoekers ontdekten dat een complexe interne structuur, met meer schuilplaats, resulteerde in een grotere visstand, biomassa en soortenrijkdom. De resultaten …

In this study, the effect of four preservation techniques (frozen, freeze-dried, and air-dried at 40 and 70 °C) on the protein extractability, …

Marine debris is a growing global problem. Due to the wide ocean dynamics worldwide, predicting the transport of floating marine debris, such as plastic, is difficult. Although large-scale distribution patterns and accumulation zones are recognised and reproduced by numerical models, small-scale prediction …
