Conclusions from such experiments will promote the understanding of ecological resilience*, which is essential to sustain and repair aquatic ecosystems in the future and thereby secure important resources on which we depend. * Note: Resilience = the amount of disturbance a system can absorb without changing to another state of attraction. The three themes of the research group: Consequences of predator declines for coastal resilience to eutrophication: Participants: Katrin Sieben PhD; Cooperating partners: Ulf Bergström, Lars Ljungren & Alfred Sandström – Swedish Board of Fisheries. In this project we study how important predator communities are for food-web structure and function. We test how predator diversity through different degrees of omnivory and carnivory, influence top-down control in benthic communities. In this project we also specifically explore the impacts on marine communities from the documented large-scale and world-wide eutrophication of aquatic habitats the last 50-60 years, and an even historically longer strong exploitation of marine resources (fishing and hunting). Consequences of ecosystem engineers for the trophic structure and recovery potential of the Wadden Sea ecosystem: Participants: Serena Donadi PhD, Johan Eklöv post-doc; Cooperating partners: Theunis Piersma, Els van der Zee –Animal Ecology, University of Groningen; Han Olff, Tjisse van der Heide – Cocon, University of Groningen. Henk van der Veer, Johan van der Koppel – NIOZ. In this project we study interactions between benthic soft-bottom communities dominated by ecosystem engineers and local resource conditions. We suggests that feedbacks between ecosystem engineers and local resource conditions generate alternative stable benthic communities with distinctly different trophic structures and function. We specifically study engineering effects of sediment destabilizing ecosystem engineers (seagrass, mussels, cockles) and sediment stabilizing suspension feeders (polychaete worms), and how such relations may be modified by human impacts on sediment stability (dredging, trawling, engineering). The relation between biodiversity and resilience in source-sink meta communities: Participants: Karin de Boer post-doc. Cooperating partners: Birte Matthiesen, Lena Eggers – Leibnitz Institute for Marine Sciences. Helmut Hillebrand - Planktologie, University of Oldenburg. In this project we aim to predict consequences of species loss for the ability of communities to cope with environmental stress and disturbances, i.e. community resilience. To test this we establish meta communities consisting of connected habitats of marine benthic microalgae in the laboratory. This means allowing for patch-dynamics by including environmental disturbance and dispersal, which are natural processes that promote species coexistence – but are so far neglected processes when it comes to biodiversity-ecosystem function experiments. Master research projects There is a number of master research projects available within the above subjects.

Interactions between long-range and short-range facilitation cascades in intertidal systems.
For decades research has mainly focused on negative species interactions such as competition and predation. Nowadays the importance of positive (indirect) interactions between species is recognized and it is indispensable when considering management plans. When a species facilitates a secondary species, this species can (positively) effect a third species; creating a cascade of facilitation that can influence e.g. biodiversity. On the mudflats of Schiermonnikoog, I study a long-range facilitation cascade created by mussel beds. Mussel beds ameliorate stressors such as sediment erosion and wave power, hereby creating a unique habitat in their landward wake where cockles prefer to settle, along with many other benthic species. Also, on the short-range, mussel beds contain water in pools on the mussel bed that provide a sheltered habitat in which biodiversity may peak and conditions are mediated.
The Dutch and German coastal salt marshes are renowned for their 'terps'. Prior to the construction of dikes, terps guaranteed a safe haven for the local populations in times of severe floods. In general, however, both archaeologists and the general public are insufficiently aware of the fact that these severe floodings took place rarely, and primarily in the winter season. A more detailed understanding of the enormous diversity there must have been in this wide-stretched landscape, both in time and space, might dramatically alter our view of the people who chose to inhabit these seemingly hostile landscapes.
As such, we might rethink (coastal) wetland exploitation in other areas as well, both from an archaeological and a contemporary world point of view.
In 2015, I was awarded NWO VENI grant to study early crop cultivation in the coastal salt marshes of the Netherlands and Germany. The project will include a very much needed review of all the data currently scattered in dozens of reports, papers and books, palaeoecological analyses on actual excavated tillage levels, and experimental crop cultivation in the present marsh.
In order to make this project a success, I participate with a number of people and institutions, both outside and inside academia. An incomplete list;
Prof.Dr. Karl-Ernst Behre, Lower Saxony Institute for Historical Coastal Research: review of crops
Dr. Welmoed Out, Moesgaard museum: palaeoecological analysis of tillage levels
Dr. Niek Scheepens, University of Tübingen: partner for experimental agriculture
It Fryske gea, Landscape organisation of the province of Friesland: experimental agriculture
Café Hammingh: public outreach, restaurant will use my data as inspiration for a menu
