Abstract

This research reveals the results of 34 algological samples collected in marine littoral and inland water bodies of Galindez Island. Samples were collected in February–March 2004 from the surface of thalli of macrophytic algae Cystoseira nehlecta, Sargassum sp., Undaria pinnatifida, and shells of Nacella concinna, rocks, snow, and ice. A total of 64 taxa belonging to five divisions of algae were revealed. Diatoms (56 species) made up the majority in species diversity; cyanophytes (4 species), chlorophytes (2), chryzophytes (1) and dinophytes (1) were poorly represented. In marine littoral of Galindez Island 51 species were recorded, and 13 species occurred in inland lakes. Coscinodiscus radiatus, Odontella aurita, and Thalassiothrix longissima dominated in marine littoral. Microcystis pulverea, Gleocapsa magma, Phormidium tenue, Aulacoseira islandica, Chlamydomonas nivalis, and Monoraphidium antarcticus were abundant on the snow and ice surface coloring it in yellow-green and red tints.
