Structure, diversity & stability of foodwebs in coastal ecosystems This PhD research aims to analyse the mechanisms providing food webs resilience against stressors and perturbations. Within the Belgian part of the North Sea, food webs of reefs with a different complexity will be defined and the underlying structures of these food webs will be examined. In order to achieve this as many different species as possible have to be gathered from each reef, together with environmental data, sediment particulate organic matter and water particulate organic matter
