The study started with the classification and description of the plant communities based primarily on phytosociological and biodiversity data. All data were obtained from 2003-2004 to 2011-2012 austral summers. 12 most frequent lichen-moss association species based on all island records were found. The most frequent association in both studied areas involved foliose-crustose lichen with a moss carpet species, such as Psoroma cinnamomeum Malme with Sanionia uncinata (Hedw.) Loesk. The occurrences for each island as well as the common association found in all sampled islands are demonstrated. Keywords: lichen ecology, bryophytes, South Shetlands archipelago, Maritime Antarctic Introduction The composition, abundance and distribution of the plant communities in Antarctica is directly related with the changes in the climatic conditions and the effects of climate warming, resulting in alterations including changes in populations (Frenot et al., 2005; Convey, 2006). Lichens is the group that has the highest species diversity, meeting the conditions best adapted in Antarctica, having an important contribution in floristic composition in these areas, and their existence is dependent on ice-free regions, climate and a stable substrate (Redon, 1985; Kappen & Schroeter, 1997). Lewis-Smith (2001) in a phytosociological study found that many species of mosses are associated with dominant species in the formation, reflecting the dependence of these species of mosses because if the dominant species become endangered, the dependent one will become endangered too. Studies on the coexistence of terrestrial algae species and lichenized fungi were also published, such their relationship within the growth habit and ecological adaptation in the Antarctic environment. Associations are reported between mosses and lichens species, and plant formations growing in associations at King George Islands, Nelson Island and Elephant Island (Allison & Lewis-Smith, 1973; Pereira & Putzke, 1994; Victoria et al., 2006). A mapping of these plant formations is being conducted to infer the environmental changes as well the human impact over the years of the plant composition in the Antarctic ice-free areas. In order to complement the knowledge of plant communities in the ice-free areas of Maritime Antarctic, associations between lichens and mosses observed during the phytosociological survey made since 2003-2004 up to 2011-2012 austral summers are presented here, as well as the strongest associations found in each surveyed island together with their coverage and frequencies. Materials and Methods Using the phytosociological data obtained since 2003/2004 up to 2011/2012 austral summers all records from lichens found associated to moss species were analyzed. The data was obtained from a survey using Braun-Blanquet phytosociological methods (Braun-Blanquet, 1964), adapted to Antarctic conditions (Kanda, 1986). Whenever possible, samples of lichens with highly developed ascomas (presence Science Highlights - Thematic Area 2 | 67
