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).

Presentazione
2013
Il testo propone un articolato commento alle posizioni teoriche e alle linee di ricerca progettuale espresse da Michele Argentino, professore ordinario di Design a Palermo circa la necessità di riconquistare il ruolo sociale alla creatività individuale, riprendendosi il desiderio di diventare nuovamente "Homo Faber". Il testo inoltre presenta gli obiettivi della nuova collana scientifica - diretta dall'autrice - dal Titolo " Design e Contesti": intercettare ambiti di ricerca trasversali alle discipline del progetto, favorire gli intrecci tra idee progettuali e percorsi di innovazione socio-culturale, sviluppare nuove strategie produttive compatibili con i diversi aspetti della sostenibilità.
L’ILLECITO ANTITRUST DOPO LA DIRETTIVA 2014/104/UE
2020
Tradizionalmente, tanto a livello nazionale quanto a livello comunitario, la tutela della concorrenza si è caratterizzata per l’impiego di strumenti di enforcement pubblicistico. Dopo un lungo iter, il 26 novembre 2014 è stata pubblicata la direttiva del Parlamento Europeo e del Consiglio UE 2014/104 relativa a determinate norme che regolano le azioni per il risarcimento del danno ai sensi del diritto nazionale per violazioni delle disposizioni del diritto della concorrenza degli Stati membri e dell'Unione europea. In Italia il recepimento della Direttiva è avvenuto il 19 gennaio 2017 con il d.lgs. n. 3/2017. Sebbene la normativa in parola intervenga a colmare il vuoto creato dall’assenza, …
Foreign direct investment and the rule of law in Africa in the context of legal integration
2018
This essay focuses on the relationship between foreign direct investment (FDI) and the rule of law in the context of legal integration in Africa, outside of the AfCFTA agreement. Specifically, the essay investigates the concept of the rule of law, taking into account its ‘dynamic’ side, that is the power to shape and model the structure of a state using the example of OHADA. The OHADA framework shows that the relationship between foreign direct investment (FDI) and the rule of law is not unilateral but a ‘two-way mutual’ relationship where both actors contribute to the success of the system, adapting to each other in order to achieve their respective goals.
