Plant Extracts as Antimicrobial Agents in Sustainable Conservation of Erythrina caffra (Fabaceae) Historical Trees
2023
Microbial colonization plays a relevant role in the biodegradation and biodeterioration of cultural and natural heritage, representing a revealing problem in conservation strategy. In this study, the essential oil (EO) and hydro-alcoholic extract (HAE) of Origanum vulgare L. (Lamiaceae), an aromatic perennial plant, representative of the Mediterranean basin, growing spontaneously and cultivated all over the world, were analysed. Natural products, such as essential oil and hydroalcoholic extract, have strong antiseptic and antimicrobial properties and are ad hoc applied for the sustainable conservation of Erithryna caffra (Fabaceae). The main taxa revealed in the damaging of these arboreal h…
Tourism Development in UNESCO Natural Heritage Sites: The Case of Sicilian Volcanic Sites: Mount Etna and Aeolian Islands
2017
Local development often depends on tourism, especially in fragile contexts like islands which represent a special cluster and are the best cases to be analyzed in order to highlight positive and negative aspects of economic development driven by tourism. A sustainable development approach should be taken in account and the UNESCO brand plays a fundamental role in this sense. The aim of this paper is to analyze the link between tourism supply and the growth of tourism demand in the case of UNESCO sites through multivariate regression analysis. The results show a correlation between the variables considered. But the actual structure of supply is still built on conventional sea tourism and is …
Red list of threatened vascular plants in Italy
2021
Italy has a rich natural heritage, which is dangerously under pressure. In recent years, there is an increased awareness of the crucial role of plants in ecosystem functioning and in providing ecosystem services. Consequently, an updated Red List of the Italian vascular flora was compiled in this work, at the request of the Ministry for Environment, Land and Sea Protection, with the scientific support of the Italian Botanical Society. The IUCN Red List criteria were applied to 2,430 Italian native vascular plant taxa to assess their current extinction risk and to highlight the major threats affecting the Italian flora. Our results revealed that 54 taxa (2.2% of the assessed taxa) are extinc…
