Nuova stazione di Euphorbia serrata in Sicilia
2007
A new record of Euphorbia serrata (Euphorbiaceae) from Sicily. - Euphorbia serrata L. is reported from a new locality in Sicily near Mazara del Vallo (Trapani). Data on the biological cycle and the phytocoenosis in the new Sicilian locality are also reported.
Depositional environment and biofacies characterisation of the Triassic (Carnian to Rhaetian) carbonate succession of Punta Bassano (Marettimo Island…
2007
AThe aims of this study are to reconstruct the geological setting of the Punta Bassano series (Marettimo Island, Egadi Archipelago, western Sicily) and its palaeogeographic evolution. The reference section for the Upper Triassic of Marettimo shows an alternation of marl and limestone beds together with brecciated levels. The limestones are both homogeneous mudstones with evaporite pseudomorphs and laminated with fenestrae. Foraminiferal, palynomorph, and ostracod associations constrain the Punta Bassano sequence to the Carnian-Rhaetian interval. The Punta Bassano succession represents a shallow inner ramp, ranging from open-marine environment with good water circulation to lagoonal and peri…
The last of the large-sized tortoises of the Mediterranean islands
2022
Altres ajuts: CERCA Programme/Generalitat de Catalunya Altres ajuts: Operational Programme Research, Development and Education Project (CZ.02.2.69/0.0/0.0/16_027/0008360) Archaeological investigations carried out in the cave Zubbio di Cozzo San Pietro, Bagheria, Sicily, revealed the presence of a few skeletal elements of a large-sized tortoise in a funerary area dating to the Copper/Bronze Age. The tortoise has been AMS-dated revealing an age of 12.5 ± 0.5 kyr BP and therefore it pre-dates the funerary activities. The morphology of the retrieved skeletal elements differs from that of the only native tortoise currently living in Sicily, Testudo hermanni. The tortoise's size significantly exc…
Facies stacking and extinctions across the Triassic–Jurassic boundary in a peritidal succession from western Sicily
2017
An uppermost Triassic–lowermost Jurassic carbonate platform succession, which is 430 m thick, in northwestern Sicily is described with the aim to provide new data on the sedimentological and biological variations across the Triassic–Jurassic boundary in peritidal environments. The studied succession belonged to the rimmed carbonate shelf that developed during the upper Triassic along the margins of the Ionian Tethys. The peritidal sediments consist of metre-scale shallowing-upward cycles formed by subtidal, intertidal and supratidal facies. Three main informal units are differentiated along the section on the basis of the variations recorded by the subtidal facies. The lower and middle unit…

Disrupting resilient criminal networks through data analysis: The case of Sicilian Mafia
2020
Compared to other types of social networks, criminal networks present hard challenges, due to their strong resilience to disruption, which poses severe hurdles to law-enforcement agencies. Herein, we borrow methods and tools from Social Network Analysis to (i) unveil the structure of Sicilian Mafia gangs, based on two real-world datasets, and (ii) gain insights as to how to efficiently disrupt them. Mafia networks have peculiar features, due to the links distribution and strength, which makes them very different from other social networks, and extremely robust to exogenous perturbations. Analysts are also faced with the difficulty in collecting reliable datasets that accurately describe the…
L'articolata struttura familiare, culturale e politica dei Chiaromonte
2015
L'articolo ripercorre la storia della famiglia Chiaromonte, che nel Trecento riuscì ad effettuare una straordinaria ascesa sociale grazie a un'abile strategia matrimoniale e politica. Il principale esponente della famiglia fu Manfredi, che divenne vicario del Regno di Sicilia, duca di Gerba e commissionò la realizzazione del soffitto ligneo della Sala Magna dello Steri di Palermo.
Land consolidation policies in sicily and their effects on its farmland
2014
The paper deals with the legislative interventions in the field of land consolidation and their effects in improving the Sicilian land property structure. After a preliminary analysis of the legislative framework at national and regional level, a study on the structural evolution of the farming system in Italy and Sicily during the 1961-2010 period was carried out. In order to appreciate the actual impact and the relative efficacy of such interventions, data concerning the actions for land reorganization provided for by the Measure 4.11 contained in the 2000-2006 ROP for Sicily were analysed. On the basis of the data provided by the Regional Board for Agricultural and Food Resources, it has…
Human influence on faunal turnover during Early Holocene in Sicily
2012
Session: Environment, climate and human impact: the archaeological evidence AIQUA CONGRESS 2012 February 15-17 Pisa, Italy 71 HUMAN INFLUENCE ON FAUNAL TURNOVER DURING EARLY HOLOCENE IN SICILY Petruso D., Sineo L. Dipartimento di Biologia Ambientale e Biodiversità, University of Palermo, Via Archirafi, 18, 90123 Palermo, Italy The faunistic analysis at the Late Pleistocene-Holocene transition in Sicily allows to understand the ecologic and/or human role in the faunal turn over of the island. Following the work of Petruso et al. (in press) we assessed that at the Pleniglacial-Late Glacial interval, in supposed absence of human occurrence, were already extinct the last endemites (the middle s…
San Calogero eroe mietitore: continuità rituali, tempi delle feste e ritmi ergologici in Sicilia
2020
Le “somiglianze” tra antico e presente rituale non sono né accidentali né, necessariamente, frutto dell’adozione di certi modelli “forti” derivati da contatti culturali. Sono, piuttosto, specifici atti di parole, costruiti a partire da una langue simbolica comune (un apparato simbolico, sostanziato di credenze con valore cognitivo, diretto a riempire di senso i discreta culturalmente estrapolati dalla “realtà”) formatasi al momento dell’affermarsi dei regimi di vita neolitici. L’emergere, al momento del passaggio a un’economia agricola e a forme di insediamento stabili, di nuovi problemi socio-ecologici aveva imposto all’uomo, infatti, l’adozione di nuove configurazioni simboliche che organ…
