Subsurface flow and large-scale lateral saturated soil hydraulic conductivity in a Mediterranean hillslope with contrasting land uses
2017
Abstract The lateral saturated hydraulic conductivity, Ks,l , is the soil property that mostly governs subsurface flow in hillslopes. Determinations of Ks,l at the hillslope scale are expected to yield valuable information for interpreting and modeling hydrological processes since soil heterogeneities are functionally averaged in this case. However, these data are rare since the experiments are quite difficult and costly. In this investigation, that was carried out in Sardinia (Italy), large-scale determinations of Ks,l were done in two adjacent hillslopes covered by a Mediterranean maquis and grass, respectively, with the following objectives: i) to evaluate the effect of land use change o…
A new association of relict maquis with Ptilostemon greuteri (Oleo-Ceratonion, Quercetea ilicis), located in a circumscribed area of north-western Si…
2022
This paper illustrates the results of a survey aimed at deepening available knowledge on the ecology of Ptilostemon greuteri (Asteraceae), a very rare palaeoendemic and relict nano-phanerophyte discovered about 15 years ago on Monte Inici, near Castellammare del Golfo (province of Trapani, north-western Sicily). Two plant communities characterised by P. greuteri are described in detail; they occur in the locus classicus and in a second, recently discovered stand, which is also very localised and threatened by fire. The field investigations revealed that the sites where the species grows are very similar from the ecological point of view; in fact, both of them are located on the steep slopes…

A test on Ellenberg indicator values in the Mediterranean evergreen woods (Quercetea ilicis)
2015
The consistency and reliability of Ellenberg’s indicator values (Eiv) as ecological descriptors of the Mediterranean evergreen vegetation ascribed to the phytosociological class Quercetea ilicis have been checked on a set of 859 phytosociological releves × 699 species. Diagnostic species were identified through a Twinspan analysis and their Eiv analyzed and related to the following independent variables: (1) annual mean temperatures, (2) annual rainfall. The results provided interesting insights to disentangle the current syntaxonomical framework at the alliance level demonstrating the usefulness of ecological indicator values to test the efficiency and predictivity of the phytosociological…
Dematiaceous Hyphomycetes from Bosco Isola (S Italy) Mediterranean maquis litter
2010
This is the fifth contribution to the knowledge of Dematiaceous Hyphomycetes colonizing the litter in Mediterranean maquis. Twelve species are described and notes on the morphological characters are pointed out. Three of them are reported as genus, they need an examination of more material
More Dematiaceous Hyphomycetes from Pantelleria Mediterranean maquis litter
2009
This is the second contribution to the knowledge of Dematiaceous Hyphomycetes found on different plant litters from Pantelleria mediterranean maquis. Four new species are proposted while others are identified only as genera because of the scanty material found.
AN INITIAL STUDY INTO THE ENERGETIC CHARACTERISTICS OF SEVERAL VEGETATIVE SPECIES OF THE MEDITERRANEAN MAQUIS
2008
Recent years have seen an ever increasing interest in renewable energy resources. The use of these renewable resources plays a key role in the reduction of greenhouse gases and in guaranteeing a supply of energy for the future. A promising alternative to fossil fuels are lignocellulosic biomass feedstocks; a widely available, versatile source of energy able to substitute fossil fuels in many ways. The continuing growth of the Biomass sector is leading to a flurry of research into new plant species with good calorific properties and combustion persistence. It would seem that a large number of native Mediterranean maquis shrubs, once used by the local populations for heating and cooking, (car…
