Le variazioni delle superfici a faggio nel Parco delle Madonie (Sicilia): effetto del cambiamento climatico o della diversa pressione antropica?

2019

Le faggete siciliane sono di rilevante interesse fitogeografico ed ecologico perché vegetano al limite meridionale dell’intero areale di distribuzione europeo della specie. Il faggio in Sicilia caratterizza nettamente il paesaggio montano dell’Isola, raggiungendo il limite superiore della vegetazione arborea. L’areale siciliano ricopre una superficie di circa 16.000 ha, legato alle principali vette e alle alte pendici dei Monti Madonie, Monti Nebrodi ed Etna. Recenti studi hanno evidenziato che il 40% circa delle faggete siciliane sono potenzialmente a rischio a causa delle condizioni climatiche estreme. Contestualmente, alcune ricerche hanno avanzato l’ipotesi di un incremento delle superf…

Boschi di neoformazione in Italia: approfondimenti conoscitivi e orientamenti gestionali

2019

Nelle regioni meridionali, e in Sicilia in particolare, la fisionomia della vegetazione forestale post-abbandono è quella della macchia o arbusteto che difficilmente evolve verso un bosco propriamente detto. Il processo evolutivo della vegetazione spesso non raggiunge lo stadio di bosco non perché le condizioni ambientali non lo consentano ma per due ragioni fondamentali: i disturbi, in particolare gli incendi e il pascolo, e le limitazioni nell’arrivo di propaguli, causate dalla mancanza di piante madri, dei dispersori dei semi o entrambi. Infatti, in contesti favorevoli (assenza di disturbi e arrivo dei propaguli) la vegetazione evolve sino al bosco. Le formazioni preforestali frutto dei …

Characterization of mitotic chromosomes of four species of the genus Diplodus: Karyotypes and chromosomal nucleolar organizer region phenotypes

1996

Karyotypes have been described in four Mediterranean species of the genus Diplodus (Teleostei, Sparidae), D. vulgaris, D. puntazzo, D. sargus and D. annularis. Chromosomes were mainly acrocentric in all but D. vulgaris, where certain chromosome pairs were subtelocentric. A remarkable intraspecific heteromorphism in the number of NOR-bearing chromosomes along with a substantial interspecific variability in position of chromosomal Ag signals have been encountered. The presumed origin of multiple NOR-bearing chromosomes in Diplodus species and variation of the NOR location is discussed. ? 1996 The Fisheries Society of the British Isles

Deformation mechanism and hydraulic properties of normal and strike-slip fault zones in porous carbonates outcropping in central and southern Italy.

2013

Deformation of porous carbonate grainstones takes generally place by compactive shear banding, which initially produce single bands that may evolve during incremental strain into zones of multiple bands and, eventually, fault zones with discrete slip surfaces. The several processes associated to increased deformation are recorded in the aforementioned structural elements. In fact, they are characterized by a different texture, porosity, dimensional attributes (length, thickness, displacement). Fault zones are characterized by inner fault cores made of cataclastic material surrounded by thicker damage zones including single bands and zones of bands. In this work, we present the results of in…

A thermal inertia model for soil water content retrieval using thermal and multispectral images

2010

Soil moisture is difficult to quantify because of its high spatial variability. Consequently, great efforts have been undertaken by the research community to develop practical remote sensing approaches to estimate the spatial distribution of surface soil moisture over large areas and with high spatial detail. Many methodologies have been developed using remote sensing data acquiring information in different parts of the electromagnetic spectrum. Conventional field measurement techniques (including gravimetric and time-domain reflectometry) are point-based, involve on-site operators, are time expensive and, in any case, do not provide exhaustive information on the spatial distribution of soi…

TANGIBLE AND INTANGIBLE HERITAGE IN THE MEDITERRANEAN SUSTAINABLE CITY

2013

This contribution is about the enhancement of the tangible and intangible cultural heritage and acknowledgement of environmental sustainability principles. It deals with the relationship between new ways of conceiving urban environments and new strategies for urban regeneration in northern and southern Mediterranean cities. Our main research hypothesis will show how the cultural heritage is now the force for change in Mediterranean cities, and involves stakeholders, craftsmen, local inhabitants and consumers. The case studies of Tunis and Marseille will help to address the issue of the enhancement of historic city centres and the redevelopment of abandoned industrial areas. In Tunis we will…

Sine cura. Verso il ri-ciclo dell'architettura del secondo Novecento

2019

Gli argomenti discussi nel saggio interrogano il destino che il Codice dei Beni Culturali (2004- 2011) determina per le opere del secondo Novecento. Nella costruzione del futuro di questi manufatti, che per funzione, tecnologia e cicli d’uso sono spesso segnati dall’obsolescenza e dall’abbandono, le ambiguità e le incongruenze delle attuali procedure legislative sollecitano profondamente il ruolo culturale delle esperienze di ricerca che usano metodologie meta progettuali. Il confronto fra alcuni casi italiani ed altri europei rimarca il ruolo del progetto nella costruzione di una prospettiva di tutela trasformativa per il costruito del secondo Novecento. Nel quadro di azione marcato dall’o…

Settore ICAR/14 - Composizione Architettonica E UrbanaThe essay questions the future's possibilities to operate on the buildings of the second half of the twentieth century according to the Italian Code of Cultural Heritage (2004-2011). When arguing how to encourage the re-use of these artifacts which are often marked by short-life technology cycles obsolescence and abandonment the ambiguities and inconsistencies of current legislative procedures deeply stress the cultural role of research experiences that use project-oriented methodologies. The comparison between some Italian and other European cases highlights the role of a design approach in the construction of a transformative protection perspective for the built matter of the second half of the twentieth century. In a framework aiming to encourage a reconciliation between the recent built environment and the new paradigms of sustainability and circular economy architecture must recognize re-cycle practices as a main theoretical and procedural node. To modernize the late Modern built environment with contemporary construction components is not simply a matter of technical knowledge and expertise: but a theme with theoretical density aesthetic and ethical values. The architectural project in this field today must ask for greater congruence between the bureaucratic and administrative levels and the real consistency of this corpus. It is a matter of identifying strategies to equip it with capabilities meanings and contents remembering that demolition wastes have unsustainable environmental costs and uncertain results concerning the necessary new attribution of political and semantic meaning that these places await.

Dopo l'obsolescenza. Progetti per i viadotti ferroviari dismessi

2013

This article focuses on the increasing number of abandoned railways converted into new parkways, briefly investigating them trough the prism of obsolescence. Over the past forty years, the features matching with the average lifetime of infrastructural buildings have became of growing relevance dealing with contemporary policies in restructuring our territories. In the beginning of 21th century, facing the new challenges of the post-carbon era, cities of developed society are riddled with technical ruins, testaments to their recent productive past. Since the entanglement of transport infrastructure, industry and architecture highly represents important segments of 20th century urban tissues,…
