The community of Cystoseira brachycarpa J. Agardh emend. Giaccone (Fucales, Phaeophyceae) in a shallow hydrothermal vent area of the Aeolian Islands (Tyrrhenian Sea, Italy)

摘要

A Cystoseira brachycarpa community from a vent area off Panarea Island (Italy) was investigated in two sites at different pHudvalues. At low pH, species richness and coverage were low and the community displayed a reduced reproductive capacity.udConversely, at normal pH, dense canopies of fertile C. brachycarpa were found.
