Sediment migrations drive the dynamic of macrobenthic ecosystems in subtidal sandy bedforms

A traditional taxonomic approach coupled to a biological traits analysis was conducted in order provide new insight into macrobenthic communities associated with subtidal sandy environments. Results suggest that the macro-scale distribution of benthic is mainly driven by migration rate bedforms (sandbank, barchan dune and transversal dune) which changes sediment grain size reduces diversity. classic scheme species/traits succession also observed from less more physically disturbed areas. Finally, high frequency events homogenized between troughs crest bedforms. As areas are targeted for commissioning offshore windfarms information provided present paper will be particularly useful implement environmental impact assessment required such activities at sea.
