About Marine biodiversity

By integrating molecular, ecological, and palaeoecological time series across spatial scales we elucidate the response of marine organisms to past, present and future environmental change.

We live amid a global wave of anthropogenically driven biodiversity loss: species, population extirpations and, critically, declines in local species abundances. Additionally, current extinction rates are higher than would be expected from the fossil record. Global effects of increased CO2 in the atmosphere are translated not only in higher temperatures, but also in ocean acidification in oceans and seas. This is predicted to have serious implications on the capacity of organisms to grow carbonate skeletons, as well as on surface water productivity and the nitrogen cycle.

In the Research Group Marine Biodiversity, past, Present and Future, we will study selected organisms which are known to be sensitive to such changes, ranging from microbes, benthic micro- and macro fauna to holoplankton. It is crucially important to obtain a deeper understanding of the resilience of marine biota in the context of global change.


Members of the group Marine Biodiversity contribute lectures and hands-on labs to BSc and MSc Biology and Geology courses at Dutch universities in Leiden, Amsterdam and Utrecht. In addition, we regularly supervise individual research projects at BSc or MSc level. If you are interested, drop any of the researchers an email.
