Abstract

Biogenic habitat structures play a major role for distribution pattems of benthic fauna. Tube-dwellingpolychaetes provide one of the main features in the otherwise relatively low structured sandy intertidal. Theaim of this study was to investigate the effect of the tube-dwel[ing sand-mason Lanice co...
