Research Interests

For many organisms in a shallow sea such as the Wadden Sea, all starts with microalgae: free floating phytoplankton or microphytobenthos in and around the bottom. Our main aim is to investigate how the growth of these micro algae is regulated by nutrients and other resources, and how these resources, thus, shape the species composition and functional behaviour of microalgal communities. We have shown already that a shift in nutrients, results in a shifting balance in algae also. We try to find out if this shift has implications for different stages of filter-feeding bivalves. We address these questions with experiments, as well as field measurements, some of which are long term measurements with automated equipment. This way we gather essential information on the direction and magnitude of changes in the carrying capacity of the Wadden Sea, as a result of management policies or global change.

· IN PLACE (Integrated Network for Production and Loss Assessment in the Coastal Environment) - To describe and understand spatio-temporal variability in primary productivity of phytoplankton and microphytobenthos, we will setup, maintain, and exploit an automated monitoring network of two permanent stations and one ferry box in the western Wadden Sea using sensor packages that have proven successful in existing long-term monitoring programs in coastal environments. Field surveys will be organized to measure primary production and for additional mapping of water column and sediment characteristics. Basin-wide assessment of phototrophic biomass and sediment characteristics will be obtained from satellite observations and airborne images.

· P-REDUCE (Consequences of phosphorus reduction for the dynamic transfer of organic matter) – The research is based on the hypothesis that the availability of the pelagic and benthic primary producers as a food source and the food demand of their primary consumers is changing due to a decrease in P-loading, altering the structure of the food web and decreasing the potential carrying capacity. With grazing experiments we will determine how the food quality influences the development of juvenile benthic bivalve larvae and how they in return influence the composition of the algal community by selective grazing.
