Characterisation of submarine groundwater discharge offshore south-eastern Sicily
2005
A complex approach in characterisation of submarine groundwater discharge (SGD) off south-eastern Sicily comprising applications of radioactive and non-radioactive tracers, direct seepage measurements, geophysical surveys and a numerical modelling is presented. SGD fluxes in the Donnalucata boat basin were estimated by direct seepage measurements to be from 4 to 12Ls(-1), which are comparable with the total SGD flux in the basin of 17Ls(-1) obtained from radon measurements. The integrated SGD flux over the Donnalucata coast estimated on the basis of Ra isotopes was around 60m(3)s(-1) per km of the coast. Spatial variations of SGD were observed in the Donnalucata boat basin, the average (222…
I traffici illeciti nell’area del Mediterraneo. Prevenzione e repressione nel diritto interno, europeo ed internazionale
2018
Il testo presenta il tema dei traffici illeciti nel Mediterraneo, oggetto del VIII Corso “Giuliano Vassalli” per dottorandi, svoltosi a Noto nel 2017, anche in relazione ai contributi dei partecipanti ai lavori, una selezione dei quali è stata pubblicata sulla stessa rivista The text presents the topics of the illicit traffics in the Mediterranean area, which was the subject of the 8th Training Course "Giuliano Vassalli" for PhD Candidates, held in Noto in 2017. The remarks are complemented by references to the contributions of the participants selected for the pubblication in the same review.
Nei luoghi dell'accoglienza. Progetti per Lampedusa e Palermo
2014
Il libro raccoglie gli esiti della ricerca e della didattica dei Laboratori di Progettazione architettonica del terzo anno, svolti presso il corso di Laurea Magistrale in Architettura LM4 della Scuola Politecnica dell’Università degli Studi di Palermo, sul tema dell’accoglienza a Lampedusa e a Palermo. L’obiettivo è quello di presentare la composita esperienza di progetto e di ricerca prodotta intorno all’argomento e nello stesso tempo attivare un confronto sul paesaggio e sugli spazi urbani della città. Il libro cerca di sviluppare un percorso di ricognizione e di conoscenza attraverso l’elaborazione di progetti didattici in grado di produrre idee per la città e il territorio. The book con…
Malta and Sicily Joined by Geoheritage Enhancement and Geotourism within the Framework of Land Management and Development
2018
Malta and Sicily, which lie at the centre of the Mediterranean Sea, share a long history and have unique geological and geomorphological features which make them attractive destinations for geotourism. In the framework of an international research project, a study for the identification, selection and assessment of the rich geological heritage of Malta and Sicily was carried out, aiming to create a geosite network between these islands. Based on the experience and outputs achieved in previous investigations on geoheritage assessment carried out in various morpho-climatic contexts, an integrated methodology was applied for the selection, numerical assessment and ranking of geosites. The sele…

Competition among introduced and indigenous submerged macrophytes in a southern mediterranean shallow system
2011
In Termini Imerese H. stipulacea has been recorded inside artificial basins, located near the harbour, built arranging breakwater barriers along the coast in order to protect the coastal road. From July until the beginning of November the seagrass formed beds with cover values ranging from 70% to 80%, and it was in contact either with the seagrass Cymodocea nodosa (Ucria) Ascherson (cover values of 20-25%) or the green alga Caulerpa prolifera (Forsskål) Lamouroux (cover values of 10-15%). H. stipulacea in good health conditions showed a clear competition strategy with C. nodosa as proved by registered cover values. But during natural denudations occurring in winter, C. racemosa var. cylindr…
An additional record of Kyphosus vaigiensis (QuoyGaimard, 1825) (Osteichthyes, Kyphosidae) from Sicily clarifies the confused situation of the Medite…
2015
The lowfin chub, Kyphosus vaigiensis, is reported for the first time off Favignana Island, Sicily, central Mediterranean Sea. The specimen was identified on the basis of morphometric and meristic characters as well as mitochondrial DNA sequences (COI and 16S-rDNA). Two, perhaps three, Kyphosus species - K. bigibbus, K. sectatrix and K. vaigiensis - have been occasionally recorded in the Mediterranean. These species occur both in the Atlantic and Indo-Pacific regions but it is likely they entered the Mediterranean through the Strait of Gibraltar. However, it is unclear whether they have established reproductive native populations in the Mediterranean.
COASTAL ACCESSIBILITY AS VULNERABILITY FACTOR FOR PATELLA ULYSSIPONENSIS GMELIN, 1791 IN A MEDITERRANEAN MPA
2023
Average density of Patella ulyssiponensis Gmelin, 1791 was correlated with costal accessibility and tourists’ density. The results highlighted that the accessibility could have a greater weight than the MPA regulation, in absence of patrolling, on the vulnerability of this sensitive species.
CITIZEN SCIENCE: A SUCCESSFUL TOOL FOR MONITORING MARINE BIODIVERSITY
2019
The Mediterranean Sea, considered as a true hotspot of biodiversity, is currently experiencing a decline in the number of species and a deterioration of habitats, as a consequence of different anthropogenic pressures, which are predicted to increase in the future. Among these pressures, the increase of human population, habitat modification and loss, pollution, coastal urbanization, overexploitation, the intentional or indirect introduction of Non-Indigenous Species (NIS, i.e. organisms introduced outside of their natural range) and climate changes (i.e. acidification and warming) have been pointed out as the major threats to biodiversity. Therefore, biodiversity monitoring and surveillance…
Preservation of modern and mis 5.5 erosional landforms and biological structures as sea level markers: A matter of luck?
2021
The Mediterranean Basin is characterized by a significant variability in tectonic behaviour, ranging from subsidence to uplifting. However, those coastal areas considered to be tectonically stable show coastal landforms at elevations consistent with eustatic and isostatic sea level change models. In particular, geomorphological indicators—such as tidal notches or shore platforms—are often used to define the tectonic stability of the Mediterranean coasts. We present the results of swim surveys in nine rocky coastal sectors in the central Mediterranean Sea using the Geoswim approach. The entire route was covered in 22 days for a total distance of 158.5 km. All surveyed sites are considered to…
