Table 2. Mean (±SE) abundance, biomass and the number of species observed at the five habitats.
All the macrofauna was divided between those species associated to the macrovegetation or macroalgae (i.e., epifauna), and those species directly related to the seafloor substrate (i.e., seabed fauna), either buried in the sediment or attached to the rocky bed. Abundance (individuals m-2), biomass (dry weight, g m-2).
