Phytosociological and distributional researches on the grasslands of the class Lygeo-Stipetea in western Sicily.
2009
The thermo and meso-xerophilous pseudo-steppic vegetation is widespread in the driest areas of the Mediterranean Region and is primarily referred at the class Lygeo-Stipetea. This sintaxon includes communities dominated by several hemicryptophytes, which are also associated to some geophytes and therophytes. In Sicily this vegetation is distributed from sea level to 1300-1400 m, on different substrates (limestone, gypsum, schists, calcarenites, conglomerates, etc.), within the thermo and mesomediterranean belt dry to subhumid. Principally, are secondary grasslands used for grazing, localized on previously deforested areas, where the periodic burnings play a fundamental role in maintaining t…
Orophilous aspects of relictual vegetation of the class Rhamno-Prunetea localizated on the Madonie Mountains (NW Sicily).
2009
The deciduos shrubby mantle coenoses referred to the class Rhamno catharticae-Prunetea spinosae are secondary communities - sometimes permanent - localized in the climactical dominion of the forests of Querco-Fagetea and Quercetea ilicis or the riparian woodlands of Salici-Populetea nigrae. These communities are widespread from the Eurosiberian to the Mediterranean region, and are linked to rich nutrient humic soils, rocky slopes and screes (1). In Italy, the class Rhamno-Prunetea is represented by the alliances Cytision sessilifolii, Berberidion vulgaris, Pruno-Rubion ulmifolii and Salici-Viburnion opali, the latter showing hygrophilous character (2). As concerns the mountain and submounta…
