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.
Plant hunting: exploring the behaviour of amateur botanists in the field
2021
We asked what are the behavioural and logistic preferences of professional and amateur botanists when exploring flora in the field. We extracted temporal and spatial data on vas- cular plant species occurrences from three datasets of Sicilian flora: a subset of iNaturalist, a dataset collected by a Facebook group focused on the flora of Sicily and a subset of the professional database European Vegetation Archive. We used the time span of individual contributor’s activity as a proxy of their commitment to collecting information about the flora of Sicily. Climate and landscape data were used to better characterize the spatial and temporal activity of data contributors. Finally, we assessed wh…
Analysis of the bryophyte diversity of mountain ranges in Sicily.
2015
The focus of this study was an analysis of the bryophyte flora of the main Sicilian mountain ranges, i.e., Peloritani, Nebrodi and Madonie mountains, located along the northern side of the Island, the Sicani mountains, located in the west-central Sicily and the Etna, the highest and most active volcano of Europe. The overall bryoflora consists of 504 taxa, 400 mosses and 104 liverworts and hornworts. It represent the 85.3% of the whole Sicilian flora; the mosses are referred to 37 families, the liverworts together with hornworts to 31 families. The phytogeographical analysis has shown the prevalence of the Mediterranean species, with the highest value on the Sicani mountains. It is notewort…
First record of Ribes uva-crispa L. (Grossulariaceae) from the Madonie Mts., a new species of the Sicilian flora.
2011
Abstract In this study, a first record of Ribes uva-crispa L. (Grossulariaceae) – a new species of the Sicilian flora – from the Madonie Mts. is reported. The autochthonous and relict new population of Ribes uva-crispa L. (Grossulariaceae) is found on Mount Carbonara (Madonie Mts., North-Central Sicily), which is several hundred kilometers away from the Central Apenninic and the South Mediterranean locations of its distribution range. R. uva-crispa shows a distribution similar to other taxa extending from the Euro-Asiatic area to the mountains of North Africa with disjunct populations on the main Sicilian reliefs (Madonie and Nebrodi Mts.), testifying ancient phytogeographical connections. …
Social Network Analysis of Sicilian Mafia Interconnections
2019
In this paper, we focus on the study of Sicilian Mafia organizations through Social Network Analysis. We analyse datasets reflecting two different Mafia Families, based on examinations of digital trails and judicial documents, respectively. The first dataset includes the phone calls logs among suspected individuals. The second one is based on police traces of meeting that have taken place among different types of criminals. Our breakthrough is twofold. First in the method followed to generate these new datasets. Second, in the method used to carry out a quantitative phenomena investigation that are hard to evaluate. Our networks are weighted ones, with each weight catching the frequency of …

La nuova legge statutaria della Regione siciliana. Much Ado About Nothing?
2020
The article explores the “legge statutaria” n. 26/2020, recently passed by the Regional Assembly of Sicily. It tries to clarify the functioning of some legal instruments related with the form of regional government. Although it does not seem to be a “revolutionary” novelty it could be appreciated as a first step towards a more effective implementation of the norms included in the “Statuto” of one of the five Italian Regions provided of a special autonomy

Il paesaggio costiero siciliano: rischi, trasformazione e sostenibilità
2017
La costa della Sicilia, come quella di tutta la penisola italiana e di gran parte del Mediterraneo, ha subito nei decenni profonde trasformazioni, oltre la distruzione di chilometri di spiaggia. Il consumo dei litorali, purtroppo, continuerà ad aumentare nei prossimi anni e, senza una programmazione pianificatoria adeguata, l’attuale patrimonio ambientale potrebbe compromettersi definitivamente. Inoltre, il degrado ambientale e lo stato di abbandono di numerosi spazi urbani lungo la fascia costiera hanno reso poco fruibile i lungomari, sia per gli abitanti che per i villeggianti, danneggiando pesantemente anche il settore dell'economia. In questo scenario, al fine di migliorare la gestione …
