![]() Species ecological features (food webs, signs of disturbance, alien species, biogeographical range limit) were also considered as additional selection criteria. A restricted list of 12 singletons (8 for mobile and 4 for sessile macrofauna) and 33 combinations of species/taxa were identified as significant indicators of each assemblage. 78 species/taxa of macrofauna were recorded. Ecological function and precision between the two groups were found dissimilar thus species richness, abundance, macrofauna distribution and indicator species/taxa of sessile and mobile macrofauna were analyzed separately. Sessile (in percentage cover) and mobile macrofauna (in abundance) communities were identified and counted within 0.1 m 2 quadrats. Mobile boulders were sampled with a stratified random sampling design in upper and lower midlittoral zones in March–June 2015. ![]() The aim of the study is, for the first time, to assess benthic macrofaunal assemblages and to identify indicator species of each assemblage within intertidal boulder field habitats in this marine subregion. The French southern marine subregion of the Bay of Biscay presents local environmental features explaining the presence of specific communities in remarkable habitats. ![]()
