Within my PhD, I study the effect of beach management, especially the ‘Sand Motor’ mega sand nourishment, on ecological communities of sandy beaches, with a focus on the intertidal and supratidal macroinvertebrate community. Animal groups that are studied include polychaete worms, amphipods and insects. I look at community patterns in the field but also perform indoor experiments using mesocosms to unravel mechanisms of community assembly and animal-plant interactions. Special interest is assigned to the effect of differences in resource availability (diatoms in intertidal waters and beach-cast sea weed) on species interactions and macroinvertebrate community composition. Also, I aim to study the link between beach-cast sea weed and terrestrial primary production and the cross-boundary interactions between the marine and terrestrial ecosystems in general. This PhD is part of the research project NatureCoast which revolves around understanding the impact of a new coastal defence strategy, the ‘Sand Motor’, on its environment. In the end, I will be able to answer the question whether a mega sand nourishment can be considered to be an ecological friendly alternative to current beach management in terms of the macroinvertebrate community.
