Feeding ecology of the sand smelt, Atherina boyeri (Risso, 1810) (Osteichthyes, Atherinidae), in the western Mediterranean: evidence for spatial vari…
2005
The feeding ecology of the sand smelt Atherina boyeri Risso 1810 (Osteichthyes, Atherinidae) was investigated in a Mediterranean coastal basin (Stagnone di Marsala, Italy) by means of carbon and nitrogen stable isotope ratios. Sampling was carried out seasonally in 1999 in two locations characterised by different depth and vegetal coverage. Throughout the year the sand smelt showed enriched δ 13C and δ 15N values in both sampling locations (δ 13C about −12‰ and δ 15N about 12‰). This result suggests the overall importance of the benthic pathway in the food web leading to A. boyeri. Our isotopic picture is only in partial agreement with stomach content data from the literature. Stomach conte…

Stable isotopes and trophic positions of littoral fishes from a Mediterranean Marine Protected Area
2008
Stable isotope analyses were employed to explore feeding and foraging habitats and trophic levels of littoral fishes in a western Mediterranean Marine Protected Area (Egadi Islands, Sicily, Italy). Carbon and nitrogen stable isotope ratios were measured in primary producers, invertebrates and fishes collected in December 2001 and January 2002. Fishes of the littoral region of the Egadi Islands had isotopic signatures that fell into a wider range for δ13C (about 6‰) than for δ15N (about 3‰). Carbon isotope ratios were consistent with a food web based on mixed sources and two trophic pathways leading to different fish species. Differences in the isotopic composition between islands were highe…
Scarpa. Una cerniera spaziale per lo Steri
2018
Per un architetto pensare alla propria città, e un luogo specifico al suo interno, migliorarlo significa concentrarsi sulle qualità specifiche del sito da un punto di vista storico, economico, sociale e culturale. Questo scritto entrerà nei dettagli di questa riflessione, attraverso le esperienze di Carlo Scarpa e l'importante ruolo da lui assunto nella definizione dello Steri (1972-1978). Tutto ciò è diretto all'acquisizione della capacità di riconoscere la fisicità di un'architettura significativa e delle relazioni spaziali che la definiscono, come ad esempio quelle tra interno ed esterno, rendendo così il proprio concetto di soglia e di continuum spaziale. Siamo consapevoli che le scelte…
Scarpa in Sicily: The memory of our senses
2019
Per un architetto pensare alla propria città, a un luogo specifico e al suo interno da migliorare significa concentrarsi sulle qualità specifiche del sito da un punto di vista storico, economico, sociale e culturale. Questo scritto entrerà nei dettagli di questa riflessione, attraverso le esperienze di Carlo Scarpa e l'importante ruolo assunto da lui nella definizione di una possibile strategia innovativa già dalla mostra su Antonello da Messina del 1953. Il fare del maestro veneziano è volto all'acquisizione e alla capacità di riconoscere la fisicità di un'architettura significativa e le relazioni spaziali che la definiscono, come ad esempio quelle tra interno ed esterno, rendendo esplicit…
In the Name of Antigone: Migrants and Human Rights in Contemporary Urban Spaces
2022
Starting from the metaphor of the ethical conflict between dignity and rights in Antigone, the article reflects on the theme of human dignity for a critique of global inequalities. These theoretical assumptions are the basis for reflecting on the theme of contemporary international mobility of populations, which generates significant effects on the production of borders and the right to the city, highlighting new issues of social and spatial justice. In particular, with respect to the “newcomers”, claiming the “right to the city”, after claiming the “right to mobility”, very often coincides with the claim and protection of human rights, in order to build “spaces for survival”. On the one ha…
Governing the Metropolitan Dimension: A Critical Perspective on Institutional Reshaping and Planning Innovation in Italy
2019
As in other European countries, over recent decades the question of met- ropolitan government has captured political and academic attention in Italy too. The debate has been recently fuelled by a national reform introduced to create 14 metropolitan authorities to provide for new government solutions in the territories of the larger urban areas. Based on literature and empirical observation, this paper presents a critical view of that process by examining the following questions: How do metropolitan areas relate to broader Italian urban policy? How does the reform contribute to a reshaping of multi-level governance through national and local initiatives? And how does institutional reorganisa…
The spatial strategies of Italian regions
2014
Spatial planning is undergoing radical changes all over Europe. As space is greatly affected by the intersection of processes of economic restructuring and institutional reorganisation, planning tools at different scales are required to reinvent their capacity to describe local identities, spatial relations and any form of territoriality. The increased complexity of territorial change, therefore, demands planning to reshape it as a cognitive process which is able to combine the designing of the future with the emergence of new, flexible and socially recognised conceptions of space and places. In this context, regions are no longer seen merely as a background for cultural identities or the s…

Knowledge Discovery and Digital Cartography for the ALS (Linguistic Atlas of Sicily) Project
2009
In this paper the latest developments of the ALS (Linguistic Atlas of Sicily) project are presented. The ALS project has the purpose to define methodologies and tools to allow researches in the socio-linguistic field. Different types of variables (both quantitative and qualitative) are involved. The whole framework is based on the definition of ontology-based applications for the creation, retrieval, manipulation and browsing of related data. To this aim, some mapping processes have been defined. The framework eventually shows the result in many ways including spatial maps. The on-going collaboration process is a perfect example a domain hybridizing process, enabling the training on-the-fie…
