Earth in Sicilian walls: notes in progress
2011
Il saggio, inserito nel volume in doppia lingua "Architetture in terra nell'Italia del Sud", ricostruisce alcuni degli episodi e delle prassi costruttive che in Sicilia hanno visto l'uso della terra cruda nelle costruzioni edilizie. Utilizzando fonti archivistiche, bibliografiche e dirette su manufatti ancora esistenti, lo scritto ritrova la terra nei modi del fabbricare dal Cinquecento ai primi anni del Novecento, da Messina a Palermo, per la formazione di mattoni o per la muratura in "pietra e tajo", così diffusa e poco conosciuta da determinare difficoltà di interpretazione e di intervento.
Il terremoto del 1823 in Sicilia settentrionale: danni e ricostruzioni
2016
Il 5 marzo 1823 si verificò un terremoto che investì gran parte della Sicilia settentrionale. Numerosi danni si verificarono a Palermo, nelle aree limitrofe a sud e ovest della capitale, in alcuni centri delle Madonie e nelle zone situate lungo il litorale e l’immediato entroterra tirrenico da Palermo a Patti (in particolare a Naso). Il contributo intende indagare, attraverso lo studio delle opere degli autori coevi al sisma e soprattutto di una copiosa documentazione archivistica, le modalità attraverso le quali ci si raffrontò con i problemi determinati dal terremoto, dalla gestione dell'emergenza, all'analisi dei danni e delle successive ricostruzioni. Dal quadro tracciato emerge in part…
Terremoto e architettura storica. Palermo e il sisma del 1726.
2015
On September 1st 1726 Palermo was hit by a violent earthquake. Although it did not bring about the destruction of the city, the earthquake caused widespread and extensive damage to the architectural heritage. The local insti- tutions carried out a series of actions involving representatives of the technical culture. These actions affected the subsequent appearance of the urban pattern and influenced the construction methods of the time. Crossing the data taken from chronicles of the time, from maps produced after the earthquake and above all copious archival documents, the research aims to reconstruct the state in which Palermo was after that tragic event, highlighting a number of aspects. …
Urban green spaces and urban planning instruments for the protection of ecosystem services: proposals for re - thinking urban legislation in Sicily
2016
According to the Ecological Society of America (2014), more than half of the world population (3.9 billion inhabitants on a total of 7.2 billion) resides in urban areas where 75% of energy consumption and 80% of the greenhouse gases emissions are concentrated (UN-HABITAT, 2012). This data, inevitably, show cities as a patchwork of environmental issues (as well as social and economic issues) and of threats to the integrity of the ecosystem services. The damages suffered by these services, due to transformations of basic territorial resources in the name of an illusory global prosperity, continue to have negative consequences not only in environmental terms, but also in economic terms, as hig…
Seroprevalence of and risk factors for Leishmania seropositivity in a sample population of Western Sicily (Italy)
2013
Background: Leishmania is a vector-borne parasite responsible for significant morbidity and mortality worldwide. The aim of this study was to assess the prevalence of and risk factors for Leishmania infantum seropositivity in a sample of Sicilian population.Methods: A total of 260 subjects were interviewed using a standardized questionnaire and requested for an venous blood sample.Results: Overall, 36 subjects (13.8%) were seropositive against L. infantum with a statistically significant higher prevalence of positivity in older subjects (p=0.04). After adjustment for age, a higher risk for Leishmania seropositivity was found in subjects who had pets living outdoors and untreated with anti-p…
Food for flight: pre-migratory dynamics of the Lesser Kestrel Falco naumanni.
2014
Capsule The post-reproductive stage of Lesser Kestrel is crucial for migratory fuelling and survival. Aims To describe the summer pre-migratory ecology of the Lesser Kestrel in Sicily and review existing data in Southern Europe. Methods We identified the main summer roosts and then made roost counts every ten days from 2010 to 2012. We used case-sensitive modelling procedures to detect biases in counts (generalized linear mixed models), assess the annual population trends from 2005 to 2012 (TRends and Indices for Monitoring); and to model habitat preferences (generalized linear model). We sampled pellets to describe the birds’ diet during the peak month prior to migration. Results We discov…
Brassica trichocarpa (Brassicaceae), a new species from Sicily
2013
A new species of Brassica from Sicily, namely B. trichocarpa, is described and illustrated. This suffrutex was found on a calcareous peak of a mount near Palermo, where it is represented by a single population occupying a really small surface. It is well differentiated from the other perennial species belonging to B. sect. Brassica mainly in having hairy ovary and very short, thickened, hairy, not torulose fruits. Its relationships and taxonomical position within this group are examined too. An analytical key of the current taxa belonging to the genus Brassica sect. Brassica is also provided.
THE ENVIRONMENTAL IMPACT OF POWER LINES ON BIRDS IN SICILY
2018
Electrocution is a serious conservation problem worldwide for a large number of bird species (BEVANGER, 1994, 1998; BIRDLIFE INTERNATIONAL, 2004; PRINSEN et al., 2011). Due to its wide extension, it is necessary to seek methods that optimize the identification of the most dangerous pylons (JANSS and FERRER, 2001; MANOSA, 2001), lines and the highest risk areas (TINTÓ et al., 2010; GUIL et al., 2011). Actually, the data on bird mortality caused by electrocution and collision in Sicily are deficient, however, a preliminary study suggests that the White Stork (Ciconia ciconia L., 1758) is one of the most threatened species inside two Special Protection Areas (SPA) (ZAFARANA and BARBERA, 2016).…
End-Triassic Extinction in a Carbonate Platform From Western Tethys: A Comparison Between Extinction Trends and Geochemical Variations
2022
The Triassic/Jurassic boundary section cropping out at Mt Sparagio in north-western Sicily (Italy) consists of a thick and continuous peritidal succession typical of a Tethyan carbonate platform. The combined chemostratigraphic and biostratigraphic study of this section allowed us to parallel the environmental variations inferred by the isotopic records and the extinction trends recorded by the benthic organisms. In the studied section, the isotope data of C, O, and S are indicative of serious environmental perturbations related to the Central Atlantic Magmatic Province (CAMP) activity, as recorded worldwide. Two negative excursions in the C-curve (Initial-CIE and Main-CIE) confirm the acid…
