Profitability of artichoke growing in the mediterranean area
2015
Cultivation of artichokes for production is significant in the Mediterranean Basin. Italy represents an important productive hub and in this context, Sicily has been one of the foremost production areas. Artichoke production is a stable element of either specialized or mixed production systems in the region. However, due to the economic recession and increasing imports of artichokes from North African countries, many companies are undergoing crisis, with concerns for the negative impact on the socioeconomic fabric, in terms of the rising unemployment an eventual collapse of this specific activity would determine. According to the theory of economic development, a prerequisite of a territory…
First record of Eichleriella leucophaea (Basidiomycota) from Italy
2015
Eichleriella leucophaea Bres., a wood inhabiting heterobasidiomycete, is recorded for the first time in Italy. Fruiting body occurred on branch of Quercus ilex L. Description, distributional and ecological data of this uncommon taxon are here provided.
Timber anti-seismic devices in historical architecture in the Mediterranean area
2017
Questo lavoro esamina l’uso di un dispositivo strutturale in legno storico utilizzato come rinforzo della muratura per i sistemi di prevenzione sismica nell'area mediterranea. Tale tecnologia viene realizzata mediante un telaio tridimensionale tridimensionale di legno incorporato nella muratura di pietra per legare insieme le varie parti strutturali e contribuire alla resistenza sismica complessiva. Molto spesso, questo principio costruttivo fu esteso non solo per le parti più deboli, ma per l'intero edificio, creando nuove configurazioni strutturali che erano in grado di assorbire gli effetti delle azioni sismiche. Dalle esperienze costruttive di epoca romana (opus craticium), questo siste…
Environmental Radioactivity Measurements in the Mediterranean Area
2010
In the framework of an environmental radioactivity monitoring program, a research activity concerning an optimization of techniques for sampling and measurement of environmental radioactivity was performed at the Nuclear Engineering Department (DIN) of Palermo University. Al-though initially aimed to the analysis of monitoring data of the local network installed at the nuclear research reactor AGN-201 "COSTANZA" of Palermo University, in the following years the studies were oriented to improve the sampling facilities and measurement systems with the aim to achieve also detection limits as low as possible. The activity has allowed to collect numerous data of nuclide activity concentration fo…
ECOLOGICAL FEATURES OF MACROMYCETES IN EUCALYPTUS REFORESTATIONS IN SICILY (SOUTHERN ITALY)
2009
The objective of this work was to compare and estimate the ecological features of 192 macromycetes, including nine hypogeous and three semi-hypogeous fungi, collected in Sicilian areas reforested with Eucalyptus. The number of mycorrhizal fungi turned out to be only 22 % of the taxa recorded so far from other areas, and this underlines the difficulties of eucalyptus trees in adapting to the pedological and climatic conditions of Sicily.
Feudalesimi nel Mediterraneo moderno
2015
Si deve al medievista Pierre Toubert l’elaborazione della categoria di feudalesimo mediterraneo, per definire un sistema di produzione dai tratti comuni diffusosi nei secoli centrali del Medioevo in uno spazio assai ampio, che comprendeva il mondo iberico, la Francia meridionale, l’Italia, gli stati latini d’Oriente. Alla tesi di Toubert furono mossi – com’è noto – non pochi rilievi critici: la dilatazione degli spazi e dei tempi, la sostanziale omogeneità tra tutti i paesi del bacino mediterraneo, la rigidità del modello, l’inerzia o la semi-immobilità in esso rappresentate più che il cambiamento, la visione spesso frammentata in tante microanalisi. Non per questo la categoria di feudalesi…
An analysis of the bryophyte flora in Sicilian archaeological areas
2019
An analysis of the bryophyte diversity in the studied Sicilian archaeological areas was conducted, highlighting which species are more common and potentially harmful on the ruins. The floras are much diversified and the presence of some rare taxa highlights the role of refuge carried out by these areas, especially for the species of strongly threatened coastal habitats. Attention on the complexity of the relationships between restoration interventions on lithic structures and conservation needs of the rare and interesting taxa is point out.
Solanum lanceolatum (Solanaceae) in Sicily: A new alien species for the European flora
2015
Solanum lanceolatum Cav. (Solanaceae) is a species native to Central America (Mexico, Belize, Guatemala and Panama), that has been found naturalized near Sutera and Porto Empedocle (Sicily). This is the first record in Italy and Europe.

Forage mixture productivity and silage quality from a grass/legume intercrop in a semiarid Mediterranean environment
2023
In semiarid environments of the Mediterranean region, intercropping is a sustainable agricultural system of long standing. In this area, the pea (Pisum sativum L.) is one of the most commonly grown legume crops. Little information is available on the quality of silages to be obtained from forage mixtures of pea intercropped with cereals or annual grasses. In this study, two experiments were conducted over the course of two growing seasons in Sicily (Italy) with the aim to determine the biomass production of forage crop mixtures and assess, only in the second experiment, the silage quality of grass and legumes. Four cereals and one annual grass species were grown in pure stand and in mixture…
