Communities of Marmara mediolittoral caves and overhangs
Description (English)
Mediolittoral caves and overhangs with low light levels where algal growth is restricted to a very few species that can withstand low light levels, low to high hydrodynamism, and extended periods of desiccation. Canopy-forming macroalgae are overall absent whilst encrusting rhodophytes are preponderant. The communities are, however, very poor in species. Two species of Rodophyta dominate: Hildenbrandia rubra and Phymatholithon lenormandii.Other species include Gymnothamnion elegans, Corallina elongata, Isopoda: Ligia italica, Cirripedia: Perforatus perforatus, Chthamalus stellatus, and Chthamalus montagui.
