    The present study deals with the grassland complex of communities which may be found on the limestones in the southeastern Alps; these communities show in fact a particular interest for their high biodiversity degree and for their importance for the traditional land-use economy of the south-European mountain regions. Phytosociological releve´s corresponding to well-defined plant associations have been used in order to get information on the relationships among plant species diversity, biomass, chorotypes, pollination types, functional strategies and soil characteristics. The analysis was carried out both along an altitudinal and a soil evolution gradient. The analysis of the correlations among the variables and the application of the principal component analysis shows a positive correlation between soil parameters and biomass, eurichory, anemogamy and C- and R-strategies; on the contrary, a negative correlation among stenochory, entomogamy and S-strategy with the soil evolution seems to be present. This article shows how the phytosociological approach can be used to get information and knowledge on the correlations between several variables useful to understand the complex nature of the plant communities in order to support management plans

    Phytosociological overview of the Italian Alnus incana-rich riparian woods

    On the basis of data both new and coming from the literature, the Italian grey alder riparian woods were studied from the syntaxonomic point of view. The floristic-sociological analysis of 119 relev\ue9s coming from northern Italy and the comparison with phytosociological tables from neighboring areas (Slovenia, Croatia, Austria, southern Germany and Switzerland) pointed out the occurrence of two distinct associations belonging to Alnion incanae and Fagetalia: the colline-submontane Primulo vulgaris-Alnetum incanae ass. nova and the montane-high montane Aceri-Alnetum incanae. Both these associations are distributed throughout northern Italy and reach their southern limit of distribution in the Tuscan-Emilian Appenines
