Abstract
Fine-scale seabed mapping (Results showed that highest abundances of some ecosystem engineering species (e.g. the tubeworm Owenia fusiformis, and the razor clam Ensis directus) occur near bedload convergence zones resulting from a mutually evasive flood- and ebb-dominant channel system. Such zones are at the end of the channels, hence also finegrained sediments, food and larvae are trapped. The combination of the coarser-grained bedload with the deposition of fines is indeed the optimum for a lot of suspension and detritus feeders. Still, highest abundances occur at the fringes of such a system where stress levels are intermediate. Hypotheses were successfully tested along the Dutch coastal zone. Those insights are important to assess changes in seafloor integrity and hydrographic conditions, two descriptors to define Good Environmental Status within Europe’s Marine Strategy Framework Directive.
