Abstract

This study aimed to gain insight on patterns of spatial variability of seagrass epiphytes of both leaves and of rhizomes in three different habitats, continental coasts, offshore banks and islands. Moreover, we tried to discriminate between habitat-dependant variability and scale-dependant variability of Posidonia oceanica epiphytic assemblages. Results showed the absence of significant differences in the structure of assemblages of epiphytes both on leaves and on rhizomes among continental coasts, offshore banks and islands, even if the patterns of spatial variability changed among habitats. In fact, although a high variability at small scales appeared a constant pattern in epiphytic assemblages, large-scale variability resulted higher in continental coasts and offshore banks than in islands. In conclusion, epiphytic assemblages of Posidonia oceanica appear homogeneous among habitats, showing a similar structure and species composition in the same geographic area. On the contrary, differences between meadows appeared linked to local differences in environmental factors that are more evident in habitats influenced by human disturbance.
