Revision of Sarcocornia (Chenopodiaceae) in South Africa, Namibia and Mozambique
2010
Abstract Sarcocornia comprises ca. 20–24 perennial, halophytic herb and shrub species. The genus is distinct from other genera in the Salicornioideae in having flowers that are more or less equal in size, arranged in a row, and with seeds that have a membranous hairy testa and lack perisperm. Sarcocornia is distributed worldwide, mainly in regions characterized by warm-temperate and, to a lesser extent, subtropical climates. The representatives of this genus are found in habitats such as estuarine salt marshes, tidal mud flats, coastal cliffs, inland salt pans, and salt-laden alluvia of intermittent semi-desert and desert streams. Some South African taxa also occur in inland (semi-desert) q…

Il diritto islamico nel sistema delle fonti normative dell'ordinamento iraniano
2011
The essay aims to analyze the Iranian legal order by dweeling upon the connection between the religious legal sources and the secular ones. The acknowledgement of an apical right, whose origin is divine, coexists indeed with the law-making process provisions. In particular, the Author stresses the distinctive features and inherent contradictions of this legal order, which is defined as a "constitutional theocracy". Furthermore, the Author also addresses the duties of the Council of Guardians, which plays a central role in the definition of the hierarchy of legal sources, working both as interpreter of the Constitution and as controller of the compliance of ordinary and constitutional laws w…
The INGV's new OBS/H: Analysis of the signals recorded at the Marsili submarine volcano
2009
Abstract The ocean bottom seismometer with hydrophone deployed on the flat top of the Marsili submarine volcano (790 m deep) by the Gibilmanna OBS Lab (CNT–INGV) from 12th to 21st July, 2006, recorded more than 1000 transient seismic signals. Nineteen of these signals were associated with tectonic earthquakes: 1 teleseismic, 8 regional (located by INGV) and 10 small local seismic events (non located earthquakes). The regional events were used to determine sensor orientation. By comparing the signals recorded with typical volcanic seismic activity, we were able to group all the other signals into three categories: 817 volcano–tectonic type B (VT-B) events, 159 occurrences of high frequency t…
BIOMONITORAGGIO DELL’INQUINAMENTO ATMOSFERICO MEDIANTE L’USO DI LICHENI COME BIOACCUMULATORI NEL CENTRO URBANO DI MARSALA (TP)
2008
È stato avviato uno studio di biomonitoraggio nel centro urbano di Marsala. Come altre città siciliane, pur non essendo interessata da importanti attività industriali, Marsala è caratterizzata da un inquinamento legato ad attività antropiche minori, quali l’uso dei combustibili fossili per autotrazione, per il riscaldamento domestico e per la navigazione. Il contesto geomorfologico in cui si sviluppa la città, ubicata in una zona pianeggiante, non determina alcun ostacolo importante alla circolazione degli inquinanti operata dai forti e costanti venti che spirano dal mare. Il campionamento è stato effettuato nel gennaio 2007 in 27 stazioni distribuite su un’area di circa 25 km2. In ogni sta…
The Stagnone of Marsala lagoon
2009
The Stagnone of Marsala is an oligotrophic lagoon situated on the western coast of Sicily. The area has been under study since the mid-nineteenth century. Research has focused on its physiographic, chemical-physical, biological, ecological features and, particularly, on submerged vegetation. Its main biotic component, a meadow of Posidonia oceanica, is distributed among peculiar reef formations inside and outside the lagoon, which are extremely interesting from an ecological and environmental point of view. The seagrass grows near to its thermal and salinity tolerance level in the inner lagoon, where it is partially replaced by Cymodocea nodosa and Caulerpa prolifera meadows. Algal assembla…
Trophic adaptability shapes isotopic niche of the resident fish Aphanius fasciatus across lagoon habitats
2022
Abstract Coastal lagoons are characterized by high habitat heterogeneity where natural habitats coexist with artificial ones, historically set up to support human activities. Increasing anthropogenic pressure may lead to progressive degradation of the most vulnerable lagoonal habitats and the associated biological communities. One of the strictly estuarine-dependent fish species that may be affected by the degradation of lagoon habitats is the South European toothcarp Aphanius fasciatus, archetype of Mediterranean lagoon residents. Carbon and nitrogen stable isotopes were used to disentangle the influence of habitat types (natural vs artificial) and fish community (multi-trophic context) on…
A comparative study of the mollusc communities of a Mediterranean saltwork (Marsala, Western Sicily.
2018
Saltworks are peculiar artificial ecosystems and holds great interest for basic research. In fact the cooling vat (the first pond of the evaporating series) is a good example of a relatively closed area and can be considered an excellent in the field open-air laboratory, namely a mesocosm reproducing a simplified model of the natural condition of hyperaline lagoons. The aim of the present work was to analyse the structure, composition and distribution of molluscan assemblages and to identify the faunistic relationships between the cooling vat and the neighbouring basin of Stagnone di Marsala, beside considering exchanges between saltwork, Stagnone di Marsala and sea, on soft- bottom, covere…
Hyper-extended rifted margin in the Tyrrhenian Sea, upper plate of the Ionian subduction zone
2011
The Tyrrhenian Sea is a Miocene to Present back-arc basin developed in the upper plate of the Ionian subduction zone. Refraction seismic data indicate that the central sector of the Marsili Basin is a zone of thin crust ∼7 km thick compatible with its oceanic origin (Steinmetz et al., 1983). Conventional models rather define a Continent-Ocean Transition (COT) with normal oceanic crust (i.e. Finetti et al., 2005). This does not seem to be the case for the whole Tyrrhenian Basin. Serpentinized peridotites, emplaced during Pliocene, have been drilled at ODP Site 651 (Sartori et al. 2004). The W Calabria segment of the Tyrrhenian continental margin is peculiar as seismic data has excluded the p…
