Abstract
A number of rocky outcrops lay in the Northern Adriatic Sea sandy to silty floor, locally called “tegnùe”. Biologically they result as biodiversity spots where a rich and diversified phyto- and zoobenthic community takes place. Several paper deal with a full description of the zoobenthic component, whereas the information about vegetation component is scarce. We describe the macroalgal component sampled on 21 outcrops lying on the marine bottoms in front of Lido and Chioggia inlets connecting the Sea to Venice Lagoon. 94 species (59 Rodophyta, 17 Ochrophyta, 18 Chlorophyta) were determined. No seagrasses were observed as they result here completely retreated. Structure and composition of the phytobenthic component were analysed in the light of different variable parameters such as distance form the coast, depth, shape and height of the outcrops
