Inflorescence-visiting insects of a functionally dioecious wild grapevine
2018
The wild grapevine [Vitis vinifera L. subsp. sylvestris (Gmelin) Hegi] is the Eurasian dioecious ancestral form of mostly monoecious domesticated cultivars (Vitis vinifera subsp. vinifera). There are different hypotheses about grapevine pollination, varying from insect to wind pollination to spontaneous self-pollination. The aim of this paper is to update our knowledge on the biology of the wild grapevine by studying the insects visiting their inflorescences. During the fieldworks, floral visitors were observed, captured and identified. The most frequent insects visiting both sexes of wild grapevine were beetles (55%) followed by bees (45%). The present study shows that although in vineyard…
Gli approfondimenti conoscitivi e le tecniche per la conservazione delle consistenze monumentali della chiesa di Sant’Anna a Palermo
2010
Il contributo è un riassunto del progetto ed evidenzia, in particolare, gli approfondimenti conoscitivi e le tecniche per il risanamento e la manutenzione delle consistenze della chiesa, caratterizzata dalla sinuosa facciata barocca. The contribution is a graphic abstract of the project and highlights, in particular, the in-depth knowledge and techniques for the restoration and maintenance of the material consistency of the church, characterized by its sinuous baroque facade.
Interventi di conservazione degli alberi monumentali in Sicilia
2009
Gli alberi monumentali, elementi fra i più appariscenti del mondo vegetale, possono essere considerati beni unici ed irripetibili. Essi rappresentano un peculiare aspetto della biodiversità che deve essere tutelato e valorizzato alla stessa stregua dei monumenti in pietra, dei centri storici, delle grandi strutture architettoniche (Schicchi & Raimondo, 1999). Negli ultimi anni in Sicilia, come in altre regioni italiane, le iniziative volte alla conoscenza di questo particolare patrimonio culturale si sono intensificate, grazie alla sensibilità di diversi enti territoriali (comuni, province, regioni, parchi naturali). Per questa stessa regione, Schicchi & Raimondo (2005, 2006, 2007) e Schicc…

Electrochemical analysis of metallic heritage artefacts: voltammetry of microparticles (VMP)
2013
Abstract: This chapter discusses the application of the voltammetry of microparticles, a solid-state electrochemical technique, to the field of corrosion of archaeological metal. Identification of metals and alloys, identification, mapping and layer-by-layer analysis of corrosion products on metal surfaces using this technique are described. Applications include quantification of components of alloys and corrosion layers, and evaluation of metal conservation and the kinetics of long-term corrosion processes. Specific applications in archaeometry, conservation and restoration include authentication and dating.
A Raman spectroscopic and combined analytical approach to the restoration of severely damaged frescoes: the Palomino project
2008
The deterioration of art objects is normally relatively minor, controllable and attributable to environmental changes or bacterial invasion, and until now there has not been any recorded attempt to analyse an artwork that has been deliberately and significantly destroyed. The analytical problems are correspondingly larger but the potential reward from any information that can be forthcoming is thereby proportionately greater. The 17th Century Palomino frescoes on the vaulted ceiling of the Church of Sant Joan del Mercat in Valencia were largely destroyed by insurgents in the Spanish Civil War in 1936. The ensuing gunfire and a series of seven conflagrations inside the church had a devastati…
Italian marine reserve effectiveness: does enforcement matter?
2008
Marine protected areas (MPAs) have become popular tools worldwide for ecosystem conservation and fishery management. Fish assemblages can benefit from protection provided by MPAs, especially those that include fully no-take reserves. Fish response to protection can thus be used to evaluate the effectiveness of marine reserves. Most target fish are high-level predators and their overfishing may affect entire communities through trophic cascades. In the Mediterranean rocky sublittoral, marine reserves may allow fish predators of sea urchins to recover and thus whole communities to be restored from coralline barrens to macroalgae. Such direct and indirect reserve effects, however, are likely t…
