A survey of the marine algae of Milos Island, Greece

Abstract The composition of the benthic macroflora was studied in an area of shallow-water gas-hydrothermal vents in the Palaeochori Bay (Milos Island, Aegean Sea). Some species, both taxonomically and biogeographically remarkable, were collected Tribonema marinum J. Feldmann, Stypopodium schimperi (Buchinger ex Kutzing) Verlaque et Boudouresque, Amphiroa rubra (Philippi) Woelkerling, Cutleria cf. chilosa (Falkenberg) Suva, Womersleyella setacea (Hollenberg) R.E. Norris). The large number of species with warm-water affinities [ Halopithys incurva (Hudson) Batters, Jania adhaerens Lamouroux, Laurencia microcladia Kutzing, Tricleocarpa fragilis (Linnaeus) Huisman et Townsend, Stypopodium schimperi (Buchinger ex Kutzing) Verlaque et Boudouresque, Zonaria toumefortii (Lamouroux) Montagne, Anadyomene stellata (Wulfen) C. Agardh, Dasycladus vermicularis (Scopoli) Krasser, Microdictyon tenuius Decaisne ex J. Gray] is mainly due to the southern location of the Milos Island but could be also related to a homogeneous influence of vent activity throughout the bay.
