Research Interests	Top ^

Population dynamics of bivalves in the Wadden Sea are strongly influenced by the survival of juveniles in the first months of their benthic life phase. Among the mortality factors, predation by crustaceans plays a major role. The predator and prey body sizes determine the vulnerability of the young bivalves, but their growth has not yet been explicitly included in studies on predation. In this study field observations and field and laboratory experiments will be combined to investigate and finally model size-selective predation by crustaceans on growing bivalves. Through field studies at intertidal sites in the Netherlands and Germany, we want to get insight from differential predation pressure and environmental circumstances. The main aim of this study is a more quantitative comprehension of predation on bivalves.
