Macrobenthic biodiversity in intertidal habitats of the iroise biosphere reserve (Brittany, france)

摘要

Patterns of the distribution of intertidal fauna in relation to the diversity of habitats were studied in the UNESCO Man and Biosphere (MAB) reserve of the archipelago of Molene and Ouessant (west Brittany, France). A classification of environmental features was developed in order to determine species richness, abundance, biomass and trophic structure of the macrobenthic fauna in this intertidal area which covers 1120 ha.
