An Endemic Plant of the Mediterranean Area: Phytochemical Characterization of Strawberry Tree (Arbutus unedo L.) Fruits Extracts at Different Ripenin…
2022
This work focused on the extraction, quantification, and characterization of bioactive compounds of Arbutus unedo L. fruits, comparing the results obtained from the different ripening states. Extractions were performed by different methods (such as maceration extraction and ultrasonic extraction) and food grade solvents (aqueous and hydroalcoholic solvents) in each of the all ripening states (four states considered, associated with four different colors, i.e., green, yellow, orange, and red). The presence of (poly)phenols was quantified and characterized, and scavenging activity was determined by the Folin–Ciocâlteu reagent and the DPPH method, respectively. The content of bioactive compoun…
Conservation status of the endemic vascular flora of Sicily
2022
The results of a comparative study of the quantitative data of the IUCN risk categories attributed to the endemic taxa of the Sicilian vascular flora are reported. 430 Sicilian strictly endemic taxa has been evaluated by comparing the data of the risk categories attributed by published sources. 400 taxa have received at least one assessment of their conservation status, 30 taxa have not yet been considered. 278 received an assessment of their conservation status in accordance with the IUCN criteria, while the remaining 152 have not yet been evaluated according to these criteria.

Phytochemical investigation of the needles of Abies nebrodensis (Lojac.) Mattei
2019
Abies nebrodensis (Lojac.) Mattei (Pinaceae) is a species living in a very small population only in a confined area of Sicily. In this study, the dichloromethane extract of the leaves was analyzed. Apart from three already known metabolites namely dehydroabietic acid; maltol; and rheosmin, previously detected in other species of Abies, a lanostane derivative was isolated. Its chemical structure was elucidated by means of extensive spectroscopic methods.
Innovative In Situ and Ex Situ Conservation Strategies of the Madonie Fir Abies nebrodensis
2022
Abies nebrodensis (Lojac.) Mattei is an endemic species of the north-west of Sicily located in an 84 ha area in the Madonie Regional park. The current population is limited to 30 relic adult trees and a fluctuating number of juveniles of natural regeneration. The species is defined as “Critically Endangered” in the Italian list of threatened plants and is classified as CR-D in the 2000 IUCN Red List of Threatened Species. This article reports the key action undertaken by the LIFE4FIR project aimed at preserving A. nebrodensis, and the results obtained so far in three years of activity. OpenArrays SNPs genotyping revealed a high rate of inbreeding in the natural population and that the adult…
Forest nurseries and the National Recovery and Resilience Plan: the case of Sicily and Apulia (Italy)
2023
In Italy, the National Recovery and Resilience Plan (NRRP) foresees the planting of ca. 6.6 million trees to establish urban and peri-urban forests in 14 metropolitan cities. This ambitious project requires a significant number of native trees and shrubs, currently unavailable in Italian public and private nurseries. This survey analyzes the state of forest nurseries in two administrative regions of southern Italy, i.e. the “Filici” forest nursery (province of Agrigento, Sicily) and the Gargano Mountain Reclamation Consortium (province of Foggia, Apulia), to evaluate the adequacy of Sicilian and Apulian forest nurseries as potential sources of plant material to meet the requirements of the …
Osservazioni su Gai 2.14 e le res incorporales
2012
Through a critical review of some issues concerning the content of Gai 2.14 and the systematic and conceptual meaning of the res incorporales in the Gaius’ Institutes, the author defends the integration ‘ea quae iure consistunt’ (§§ 2-3) – which expresses a subjective perspective of ius (§ 3) – with new topics; it is particularly stressed that the two terms of the classification ‘res corporales / res incorporales’ – which is not possible to determine if it has been adopted first by Gaius (§ 4) – are considered by the jurist as elements of the patrimonium, more specifically from the point of view of the ways in which they enter into the patrimonium or come out from it, in accordance with a g…
