Energy self-consumers and renewable energy communities in Italy: New actors of the electric power systems
2021
Abstract The new European Directive RED-II on the promotion of the use of renewable energy sources has introduced the concept of the Renewable Energy Community. This new entity has the potential to change the relations among end-users and the latter and the other actors of the energy sector. In particular, the electrical sector appears the most influenced by the implementation of this paradigm. Indeed, the need for self-consumption and for exploiting the full potential of renewable energy in a Renewable Energy Community influences how the end-users exchange energy with the power grid, the rules for their connection to the grid, the implementation of Demand Response and other energy manageme…
I pantani di Anguillara (Calatafimi Segesta, Trapani): dati preliminari sulla biodiversità a supporto della tutela del biotopo
2016
Vengono presentati i risultati preliminari di una indagine multidisciplinare condotta in una zona umida nel territorio di Calatafimi Segesta in provincia di Trapani. L'area è di grande interesse per la presenza di rare specie animali e vegetali, di habitat minacciati tutelati da normative nazionali ed internazionali, ma anche perché è una delle ultime zone umide superstiti dell'entroterra trapanese. L'area ha subito in tempi recenti un pesante disturbo antropico che rischia di portare alla distruzione questo ambiente e il suo biota di pregio. Con questo contributo gli autori intendono supportare la richiesta di adeguata e urgente tutela del sito. Anguillara Ponds (Calatafimi Segesta, Trapan…
Report on medium-term effects of the habitat protection and restoration activities of the LIFE Project “Maintenance of the habitats of the Macalube o…
2013
The Site of Community Importance (SCI) “Macalube di Aragona” is prone to severe desertification risk. In fact, its vegetation is disturbed not only by cyclic soil movements resulting from sedimentary volcanism, but it is strongly influenced by the hostile properties of the clayey substratum (prone to intense linear erosion, badly aired, rich in salts, etc.), the long drought period (ca. 4 months) and by the long-lasting history of human pressure. Both stress and disturbance factors influence progressive succession processes, so that the most “mature” local plant communities are () the chenopod shrublands referred to Salsolo-Peganion (habitat 1430 according to 92/43 EU Directive) and the hal…
Plant species richness, biogeographic and conservation interest of the vascular flora of the satellite islands of Sicily: patterns, driving forces an…
2013
The vascular flora has been investigated on about 60 of the approximately 100 islands and islets of the Sicilian archipelago. This paper provides detailed information on the number of exclusive, rare, or threatened vascular plants living on these islands and islets. Focusing on the 18 most-investigated islets, we evaluate the extent to which species richness, rate of endemism, number of alien plants, and number of terrestrial habitats have been influenced by 1) geographical setting, 2) geological history, 3) geo-pedological variability, 4) bioclimate, 5) number and patchiness of local plant communities, and 6) natural and human disturbance history and regime. Special attention is directed t…
Towards the identification of species-specific monitoring protocol for the Italian flora of Community interest
2016
The ongoing activities for the identification of monitoring methods for the Italian flora of Community interest (FCI) are presented. The reference framework is the Directive 92/43/EEC. Monitoring is an obligation arising from Art. 11 and the results have to be reported every six years, according to Art. 17. In the last Italian National Report, covering the period 2007-2012, the status of the FCI was assessed using available knowledge and expert judgment, still revealing relevant lack of data for some plant species and, in turn, population parameters (Ercole and Giacanelli, 2014). To overcome these deficiencies, in 2015 began a project aims to set future monitoring activities and to optimize…
In situ conservation strategies of a threatened species: the case of Carex panormitana Guss. in Sicily

Assessment of the ecological status of transitional waters in Sicily (Italy): first characterisation and classification according to a multiparametri…
2010
A 1-year cycle of observations was performed in four Sicilian transitional water systems (Oliveri-Tindari, Cape Peloro, Vendicari and Marsala) to characterise their ecological status. A panel of variables among which trophic and microbial (enzyme activities, abundance of hetetrophic bacteria and of bacterial pollution indicators) parameters, were selected. Particulate organic carbon (POC) and nitrogen (PON) and chlorophyll-. a (Chl-. a) contents defined the trophic state, while microbial hydrolysis rates and abundance gave insights on microbial community efficiency in organic matter transformation and on allochthonous inputs. To classify the trophic state of examined waters, the synthetic t…
The detrimental consequences for seagrass of ineffective marine park management related to boat anchoring.
2014
Posidonia oceanica (L.) Delile meadows are recognized as priority habitat for conservation by the EU Habitats Directive. The La Maddalena Archipelago National Park (Mediterranean Sea) P. oceanica meadow. , the dominant coastal habitat of the area, is mostly threatened by boat anchoring. 12. years after the establishment of mooring fields and anchoring restrictions, a study was conducted to measure their effectiveness on the conservation of seagrass and the mitigation of anchoring damage. We found that: (i) the condition of P. oceanica was disturbed, both in the mooring fields and in control locations; (ii) mooring fields and anchoring restrictions did not show to be an efficient system for …
PROSPETTIVE E CRITICITÀ SUL RUOLO DEL BENTHOS MEDITERRANEO NELLA DIRETTIVA SULLA MARINE STRATEGY
2013
In Europe, the Marine Strategy Framework Directive (MSFD) and the Water Framework Directive (WFD) are the main regulations for the protection of water bodies. The translation of their principles into valid and practical approaches is the main challenge for the scientific community. An additional and even more severe problem is related to the MSFD application in the Mediterranean area. The aim of the present contribution is to picture the present situation in Italy, as far as the benthic communities in the MSFD are concerned, pinpoint some conceptual and practical critical points, and possibly suggest some new tools useful for the definition of Good Ecological Status (GES).
