Latitudinal Variation into the Macrofaunal Assemblages Associated to Zostera noltei Seagrass along the Atlantic Coast of Morocco

Table 7

Results of SIMPER analysis showing the average dissimilarity between the different benthic assemblages. Assemblages were identified by the hierarchical ascendant classification analysis and the species contributing in the dissimilarity of each benthic assemblage (cutoff 50%).
