The present study evaluates the relative importance of environmental factors in affecting the species composition and abundance of the plant communities on ultramafic soils in Tuscany, Italy. We used rigorous sampling techniques to test hypotheses generated from exploratory studies performed previously. Vegetation–environmental relationships were analyzed(More)
Vegetation and soil sampling were carried out in 80 plots located in five different ultramafic (serpentine) sites of Tuscany, central Italy. The physical and chemical features of each plot were determined and the species composition and cover recorded. The exchangeable fraction of soil metals was analysed because it gives a measure of their concentrations(More)

The influence of afforestation with cedars on field layer vegetation and on the germinable soil seed-bank were investigated along a 60-m transect merging from open grassland to sparse and dense canopy cover. A total of 132 species were found, 76 in the seed-bank and 109 in the vegetation, with 53 species in common. Conifer cover was not found to be(More)
The epiphytic lichen vegetation on Quercus pubescens in Tuscany, central Italy, was investigated in agricultural and nonagricultural areas along an altitudinal transect characterized by different climatic conditions. The results show that lichen communities are influenced more by climate than agricultural practices, or at least that climatic parameters can(More)
For a mycocoenological study of macromycetes in Mediterranean evergreen forests in the Siencese province, five stands belonging to theQuercion ilicis have been observed during more than two years. The phytosociological analysis of these evergreen oak woods, situated at the limit of the geographical distribution of the alliance, reveals them as intermediate(More)
