Analisi del DNA genomico nucleare di popolamenti a Cystoseira spp. nell’Area Marina Protetta di Capo Gallo-Isola delle Femmine (Sicilia nord-occident…
2008
In this preliminary study we report the first observations on nuclear DNA analysis of Cystoseira populations at Capo Gallo - Isola delle Femmine MPA (north-western Sicily). Some specific bands resulted from the DNA extraction of 2 species even though aspecific bands, probably due to polysaccarides and microendophytes were also highlighted.
Heritage and knowledge: apparatus, logic and strategies in the formation of heritage
2016
Heritage as a category reflects diverse political positions. All heritagisation processes imply the creation of hierarchies, selection, ranking, and categorization of what is worthy or unworthy of being heritage, and all heritage creation involves certain disciplinary processes that confer legitimacy. As a modern invention, heritage was built on two closely-related cornerstones: the distinction between nature and culture and the difference between normalized knowledge and marginal knowledge. As a result, refining processes were applied which became strategies to legitimise political domination. In this paper the constituent process of heritage creation and its links to normative knowledge a…

The contribution of geographical certification programs to farm income and rural economies: The case of Pecorino Siciliano PDO
2021
This study attempts to measure the capacity of the EU geographical certification scheme to positively influence the price of certified products and the incomes of their producers. A comparison of the economic results of two cheese-producing dairy farm enterprises with different business strategies and locations within the Sicilian hinterlands is performed in order to determine the transformation value of each dairy’s sheep milk into pecorino cheese (with and without the Protected Designation of Origin, or PDO, certification) and the related joint products (ricotta). The economic convenience of the total transformation of sheep milk into Pecorino Siciliano PDO and ricotta is also appraised. …
Protected areas and species: the Mediterranean Basin
1995
Éste es un estudio de Derecho internacional sobre la protección de zonas y especies en el Mar Mediterráneo. En este trabajo examino los tratados internacionales relativos a zonas especialmente protegidas y a la diversidad biológica que son aplicables en el Mar Mediterráneo. Tras una breve introducción, en la sección II analizo aquellos tratados internacionales que en esta materia son aplicables al Mar Mediterráneo, aunque expresamente no se limitan sólo al mismo. En la sección III, realizo una mención especial al enfoque y a la evolución que, sobre estas materias, se contienen en los instrumentos mediterráneos de naturaleza tanto política como jurídica. This is an International Law study on…
Biodiversity within the subfamily Alyssinae (Hymenoptera, Braconidae) in the Natural Park Peñas de Aya (Spain)
2011
Biodiversity within the subfamily Alyssinae (Hymenoptera, Braconidae) in the Natural Park Peñas de Aya (Spain). The study of parasitoid Hymenoptera is of significance for the assessment of diversity in a given area because of their role in the regulation of insects populations. The present work analyses diversity within Alysiinae (Hymenoptera, Braconidae) in the Forested Estate of Artikutza, located in the Natural Park Peñas de Aya, western Pyrenees, Spain. Collection of specimens was spread over two years and was carried out in two different habitats: mixed forest and beech forest. A total of 2,270 specimens, belonging to 22 separate genera, were captured. Subsequently, alpha, beta and gam…
Cultural and socio-economic impacts of Mediterranean marine protected areas
2000
Marine protected areas (MPAs) may be important for protecting the marine environment, but they may also have substantial socio-cultural impacts about which very little is currently known, or acknowledged. In the Mediterranean, few data are available on the socio-economic consequences of MPAs. The present study reviews the existing data on MPAs in Spain, France, Italy and Greece. A general increase in tourist activities in Mediterranean MPAs is evident, as are increases in the abundances of larger fish species, although there are no data indicating yields for fisheries increase adjacent to MPAs. A large increase in the number of divers and vessels using MPAs has already had impacts on natura…
Analysis of Protected Accidental Transients in the EFIT Reactor With the RELAP5 Thermal-Hydraulic Code
2008
The European Facility for Industrial Transmutation (EFIT) is aimed at demonstrating the feasibility of transmutation process through the Accelerator Driven System (ADS) route on an industrial scale. The conceptual design of this reactor of about 400 MW thermal power is under development in the frame of the European EUROTRANS Integrated Project of the EURATOM Sixth Framework Program (FP6). EFIT is a pool-type reactor cooled by forced circulation of lead in the primary system where the heat is removed by steam generators installed inside the reactor vessel. The reactor power is sustained by a spallation neutron source supplied by a proton beam impinging on a lead target at the core centre. A …
Connected Lands : new perspectives on Ecological Networks Planning
2017
The construction of an ecological network is a fairly complex operation, given that the components to be considered are strictly linked to the age-old problem of the relationship between man and the land, until now perhaps seen too much as a limiting relationship and not, as the use of this tool suggests, as a relationship to be safeguarded. It may represent the ideal way to reconcile human needs and the conservation of biodiversity for the sustainable management of land. This study on the ecological network represents a tool capable to contain habitat fragmentation trough a new perspective that integrates theoretical approaches and methods with planning models and experiences of local appl…
Dispersal of larval and juvenile seabream: Implications for Mediterranean marine protected areas
2015
International audience; In the marine context, information about dispersal is essential for the design of networks of marine protected areas (MPAs). Generally, most of the dispersal of demersal fishes is thought to be driven by the transport of eggs and larvae in currents, with the potential contribution of dispersal in later life stages relatively minimal.Using otolith chemistry analyses, we estimate dispersal patterns across a spatial scale of approximately 180 km at both propagule (i.e. eggs and larvae) and juvenile (i.e. between settlement and recruitment) stages of a Mediterranean coastal fishery species, the two-banded seabream Diplodus vulgaris. We detected three major natal sources …
