Univariate estimates of variance associated with each spatial scale in percentage of contribution for: total biomass and number of taxa (a), the most important species (OSM is Osmundea pinnatifida, COR is Corallina officinalis, CHO is Chondracanthus acicularis, CER is Ceramium botryocarpum, and ULV is Ulva spp.) (b) and the most important functional groups (C is corticated, AC is articulated calcareous, F is foliose, and CF is corticated filamentous) (c)
