Conservation priorities for harlequin frogs (Atelopus spp.) of Peru
2005
Populations of harlequin frogs Atelopus are declining throughout their geographical range. In Peru six of the 11 nominally described species are Critically Endangered, and there are at least 17 undescribed additional forms (all representing apparently distinct species), the conservation status of which is unknown. Most Atelopus taxa in Peru have relatively small geographical ranges, some known only from single populations, and have only a limited chance of survival. Conservation will require: (1) improvement of the faunistic and taxonomic knowledge of the genus, (2) field surveys, including in remote areas, (3) assessment of all species and populations for chytridiomycosis and research on t…
From the LCA of food products to the environmental assessment of protected crops districts: A case-study in the south of Italy
2010
In the present study, Life Cycle Assessment (LCA) methodology was applied to evaluate the energy consumption and environmental burdens associated with the production of protected crops in an agricultural district in the Mediterranean region. In this study, LCA was used as a ‘support tool’, to address local policies for sustainable production and consumption patterns, and to create a ‘knowledge base’ for environmental assessment of an extended agricultural production area. The proposed approach combines organisation-specific tools, such as Environmental Management Systems and Environmental Product Declarations, with the environmental management of the district. Questionnaires were distribute…
Analysis and approximation of one-dimensional scalar conservation laws with general point constraints on the flux
2016
We introduce and analyze a class of models with nonlocal point constraints for traffic flow through bottlenecks, such as exits in the context of pedestrians traffic and reduction of lanes on a road under construction in vehicular traffic. Constraints are defined based on data collected from non-local in space and/or in time observations of the flow. We propose a theoretical analysis and discretization framework that permits to include different data acquisition strategies; a numerical comparison is provided. Nonlocal constraint allows to model, e.g., the irrational behavior (" panic ") near the exit observed in dense crowds and the capacity drop at tollbooth in vehicular traffic. Existence …
Somatic embryogenesis in Abies nebrodensis, an endangered Sicilian fir
2022
AbstractSomatic embryogenesis, as a promising biotechnological tool for many conifer trees, has never been applied for the Abies nebrodensis species. Although all the encouraging results previously obtained by the EU LIFE (European LIFE program) funded projects in over ten years, the critically endangered Sicilian fir remains alarmingly close to extinction. In this study, we reported the first protocol of somatic embryogenesis obtained from mature zygotic embryos of the Abies nebrodensis. Seeds from Abies adult trees with specific identification numbers (IN) were collected and full seeds were identified by X-ray. Different experiments were carried out for callus initiation, from both zygoti…

Diaspora and ambidextrous management of tourism in post-colonial, post-conflict and post-disaster destinations
2019
This exploratory study aims at identifying diaspora tourism practices and at exploring its benefit in Haiti, a Carribbean island. In so doing, this research work fills both theoretical and practica...
Cheese as a food souvenir in Sicily
2022
Souvenirs are elements of territorial communication, and they are examples of the marketing strategy of destinations. Souvenirs are objects that allow us to remember moments we have experienced and places we have visited. Drawing on the close relationships between places and souvenirs, this paper analyses cheese as a food souvenir in the island of Sicily. The method is based on a qualitative design which includes visits and interviews with local sellers in the food markets and food shops in Palermo, with the objective to reveal how cheese is protected and promoted as a symbol of Sicilian culture and heritage from a marketing perspective. Results of the paper show that cheeses made in Sicily…
