LA DIMENSIONE FRATTALE DEI REEF A VERMETI

2012

Fractal geometry can be an useful tool to describe the structural complexity of a vermetid reef. Using fractal analysis of small surfaces, the fractal dimension for the outer rim of some vermetid reefs can be established. A positive correlation between fractal values and the density of Dendropoma petraeum is evident.

DISTRIBUTION AND CONSERVATION NEEDS OF A NEGLECTED ECOSYSTEM: THE MEDITERRANEAN VERMETID REEF

2014

Vermetid reefs are a key intertidal habitat in the Mediterranean. Despite recent evidence of local extinction in the Eastern Mediterranean, their role as habitat engineers and the high numbers of ecosystem services they provide, vermetid reefs are among the least known marine habitats of the Mediterranean. Here we present a literature-based study to assess for the first time their distribution inside the basin and provide evidence of a general lack of protection at Mediterranean scale.

HOW MANY NON INDIGENOUS SPECIES HAVE SPREAD ALONG ITALIAN COAST? THE ROLE OF SICILY AS CROSSROAD FOR MARINE BIOINVASIONS

The role of Plant Growth Promoting (PGP) bacteria in the growth of Mediterranean diet plants producing high-value compounds

2023

Loss of fertility, together with drought and aridity, results in soil unproductivity and eventually desertification. Unsustainable agricultural practices are currently stressing the soil: an undervalued resource that, in addition to food, provides a multitude of invaluable services such as regulating the microclimate, reducing contaminants, and capturing CO2. Hence, there is an increasing need to resort to sustainable approaches toward agricultural systems. Although Sicily is one of those regions most affected by water shortages, it is at the same time a reservoir of drought-resistant Mediterranean plants with high nutritional value and a rich microbiota. This project aims to promote agricu…

Cyclic Fluctuations, Climatic Changes and Role of Noise in Planktonic Foraminifera in the Mediterranean Sea

Gathering different marine geology data (seismics, acoustics, sedimentological) to investigate active fluid seepage (AFS) in the southern region of t…

2017

Active Fluid Seepage (AFS) at the seafloor is a global phenomenon associated with seafloor morphologies in different geodynamic contexts. Advances geophysical techniques have allowed geoscientists to characterise pockmarks, mounds and flares associated with AFS. We present a range of marine geological data acquired in the central Mediterranean Sea (northern Sicily continental margin, northwestern Sicily Channel and offshore the Maltese Islands), which allow us to identify AFSs. The AFSs are spatially distributed as clusters, aligned or isolated at different depths, ranging from few decametres offshore the Maltese Islands, up to 400 m offshore north Sicily and in the northwestern Sicily chan…

Neogene to Quaternary evolution of the Calabrian Subduction System, (Central Mediterranean)

2009

We construct an ESE striking to WNW geological cross-section across the Calabrian Subduction System (Central Mediterranean) using seismic near vertical profiles and field data. The interpreted profiles were time-to-depth converted, merged and translated in a geological section stretching from the Marsili Oceanic Basin (Southern Tyrrhenian Sea) to the Ionian accretionary complex . Moving toward the east, the resulting section through the Paola, Amantea, and Crati basins, the Coastal Chain and Sila Massif and Crotone basin. The maximum elongation of these basins change progressively moving toward the east: from NNW in the Paola to NS in the Crati to the NNE in the Crotone basins. Data we pres…

Development, human impact and habitat distribution in submarine canyons of the Central and Western Mediterranean

2015

We present in this paper different studies on canyon systems, adopting distinct approaches, temporal and spatial scales. Most of our study areas coincide with the NW Sicilian canyons, which present striking differences in their morphologies in response to the Plio-Quaternary tectonic evolution of the northern Sicilian margin. In the present-day, active sedimentary processes inferred from bedform analyses along some of the studied canyons could drive to enhanced biological activities along them. This is also confirmed by an on-going study of the impact of trawling fishery on the morphology and sedimentary environments of the Sicilian margin, where intense deep-sea bottom trawling activities …
