An Overview of the Hypogene Caves of Sicily

2017

Karst in Sicily develops in both Messinian gypsum and Mesozoic or Tertiary limestone rocks. Caves are also found in the basalts of Mount Etna. Except for some rare cases, until recently most caves developed in limestone were considered to be of epigenetic origin. The discovery of gypsum in some of these caves, and especially detailed morphological studies, have allowed defining a hypogenic origin for a dozen of caves up to now. In some of these, the hypogenic evidences are very clear, while others remain in doubt because of the widespread presence of well-developed condensation-corrosion morphologies not necessarily related to hydrothermal fluids. This paper reports the present knowledge of…

La fortuna iconografica del beato Agostino Novello in Toscana e Sicilia

2021

This paper aims to investigate the cult and iconographic critical fortune of Beato Agostino Novello in Tuscany and Sicily throughout the centuries. It deals with the analysis of the famous painting by Simone Martini Il Beato Agostino Novello and four of his miracles, on which in 1985 Giovanni Previtali had promising opinions.

Diachronic Analysis of Beech Forest in the Nebrodi Park (Northern Sicily)

2017

A comparison between the current surface of Beech forest in the Nebrodi Park (Northern Sicily) with the measurements performed in the past is here reported. 12.854 hectares of Beech forest were recognized against 10.336 hectares of 1959 with a percentage increase of 24.37%. The increase of forest is mainly due at the change of land use through a better forest management and grazing.

Syntaxonomical analysis of the beech forests from Sicily

1999

The results of a phytosociological investigation on the beech forests occurring in Sicily are given. On the basis of literature and unpublished data, four well differentiated associations have been identified and classified within the Doronico-Fagion, alliance of Querco-Fagetea. All the surveyed woodlands are localized in the mountain belt of North and North-Eastern Sicily. The associations have been examined from the floristical, ecological, chorological and nomenclatural point of view. Besides, a numerical analysis applied to the phytosociological relevés emphasizes the differences among the associations.

A SMALL INVADER CONQUERS SICILY: AMPHISTEGINA LOBIFERA (FORAMINIFERA: AMPHISTEGINIDAE)

2018

The highly invasive Amphistegina lobifera (Larsen, 1976), a benthic foraminiferal species native to the Red Sea, has colonized the Eastern Mediterranean through the Suez Canal and altered the native community structure. More recently, it has been reported from Malta and the Pelagian Islands within the Sicily channel. Here, we report new records from the southern coasts of Sicily, where we found it abundant both in the soft-bottom sediment and as epiphyt on algae. The occurrence of A. lobifera in Pantelleria and Favignana islands represents the Mediterranean westernmost record of this non-indigenous species.

Verso una dimensione narrativa delle mappe

2021

Tra il pensiero e la costruzione dell’architettura il disegno ha un ruolo baricentrico per connettere i diversi protagonisti di una realizzazione e per coinvolgere la collettività facendo percepire inedite prospettive. La scrittura si rivela utile per esplicitare ciò che nella grafica è sotteso e per stabilire un ordine nuovo nel ragionamento progettuale. I rapporti fra segni e significati si moltiplicano nei sistemi informativi recenti in cui si ha la sensazione di poter dire moltissimo (dati numerici e spaziali) ma a volte sfugge quella sintesi indispensabile per una interpretazione concreta, finalizzata alla costruzione di possibili esperienze fisiche. Per l’esplorazione dell’uso di dive…

Between the idea and the construction of the architecture the drawing plays a central role to connect the different protagonists of a project. It involves the community by envisaging unprecedented perspectives. Writing is useful to explicit the graphics and establish a new order in the design reasoning. The relationships between signs and meanings multiply in recent information systems in which it seems possible to conclude a lot (thanks to numerical and spatial data) but sometimes a synthesis is missing though that synthesis is fundamental to create new physical experiences. For the exploration of the use of different architectural languages and for the push towards the project rather than a sterile cataloging the case of the Piano Programma for the historic center of Palermo (Giuseppe Samonà Giancarlo De Carlo Umberto Di Cristina Anna Maria Sciarra Borzí 1979-82) reveals to be ambitious. Giuseppe Samonà integrates the classical representation based on Monge's projections with photographs and iconic drawings associating signs with a linguistic-structural communication capable of expressing the relationships between the parts at the basis of a morphological approach to the plan. The graphic story ("second language") of the urban fabric has creative implications expressed by images and annotations ("first language") useful for decoding them. Since the plan focuses on the potential of a storytelling that orients the imagination of its readers (designers citizens politicians) it can contribute to the study titled "B4R– BRANDING 4 RESILIENCE - Tourist infrastructure as a tool to enhance small villages by drawing resilient communities and new open habitats” as a starting point for the mapping in which GIS analysis and multidisciplinary data (geometric topological and quantitative) relating to some villages of the internal Sicily shall translate into a new architectural urban and landscape quality.Settore ICAR/14 - Composizione Architettonica E Urbana

Multivariate analysis of sites using water invertebrates and land use as indicators of the quality of biotopes of Mediterranean relic plant (Petagnae…

2007

Petagnaea gussonei is a rhizomatous, perennial scapose hemicryptophyte species belonging to a monospecific genus of Apiaceae. It lives only along woodland rivulets and is a Tertiary relic localized in the restricted area of the Nebrodi Mountains (NE Sicily, Italy). Ecological indicators have been employed to understand the status of eight localities (intermittent rivulets) where the species occurs. In order to evaluate both the rivulets' water-quality and landscape use, index of anthropisation (Ia), water fleas bioassay (TU), and analyses of water macroinvertebrates have been employed. The results obtained for the level of toxicity exclude the presence of macropollutants (TU < 0.001), where…

Studio botanico finalizzato al recupero del paesaggio vegetale dell’Area archeologica di Lilibeo presso Marsala (Sicilia occidentale)

2013

Viene presentato uno studio botanico volto al recupero del paesaggio vegetale dell’Area Archeologica di Capo Lilibeo (Marsala). Il progetto prevede l’eradicazione delle specie esotiche ad alto grado di invasività quali Ailanthus altissima e Vachellia karroo, il risanamento fitosanitario dei viali di Palme delle Canarie e la sostituzione degli individui malformati con specie ornamentali altamente decorative e a basso grado di invasività. E’ previsto l’impiego di specie afferenti agli stadi più evoluti dei sigmataxa Chamaeropo humilis- Querceto calliprini sigmetum ed al Pistacio lentisci- Chamaeropo humilis sigmetum al fine di assicurare i migliori risultati contro l’espansione della componen…
