The results of an investigation carried out on bryophyte and bryo-tracheophyte vegetation of Sicilian towns (Enna, Nicosia, Troina, Caltanissetta, Raddusa and Catania) are here shown. Twenty-two communities set into five phytosociological classes (Barbuletea unguiculatae, Grimmietea anodontis, Frullanio dilatatae-Leucodontetea sciuroidis, Adiantetea, Parietarietea judaicae) were recognized and analyzed from an ecological, taxonomic and floristic point of view. Two associations have been described for the first time: Riccio crystallinae-Sphaerocarpetum michelii ass. nova and Entosthodonto pulchelli-Parietarietum iudaicae ass. nova. The first association is to be referred to Barbuletea unguiculatae class and is characterized mostly by ephemeral, acrocarpous mosses and liverworts, typical of humid, nutrient-rich, disturbed soil. The second one can be placed within Parietarietea judaicae class, and contains both bryophytes and cormophytes, typical of weathered, eutrophic walls in shady sites. Succession patterns of communities are also proposed by considering micro-environmental gradients. In addition, life form and life strategy analysis of the bryophyte communities has been conducted to explain the adaptative trends to survive under hard conditions of urban ecosystem.
