Abstract

Dense aggregations of tube-worms can stabilize sediments and generate oases for benthic communities that aredifferent and often more diverse and abundant than those of the surroundings. If these features are to qualify as biogenicreefs under nature-conservation legislation such as the EC Habitats Di...
