Diversity, relationships and conservation of Sicilian wild taxa of Brassica: an overview
2016
Although lots of studies have been carried out through various analytical approaches and at different taxonomic levels, this overview reveals that actually a comprehensive biosystematic survey on the Mediterranean wild populations of Brassica oleracea group is still lacking.
Typification of names inDrabasect.Aizopsis(Cruciferae, Arabideae) based on material from Italy
2013
Names of 20 presumed taxa in Draba sect. Aizopsis, all based on material from Italy, are considered. Full synonymies are provided, and types are designated (for 14 names) or indicated. Most of the taxa are currently considered unworthy of recognition, of which 16 belong to D. aspera sensu lato. However, the question of whether the Sicilian populations might be distinct from the peninsular populations is still unsettled.
Ponti di Sicilia (XVI-XIX secolo). Catalogo della mostra
2015
Ad essere esposti sono stati disegni, incisioni, libri, modelli e documenti archivistici, molti dei quali presentati al pubblico per la prima volta, provenienti da archivi, biblioteche, nonché collezioni pubbliche e private, con l'intento di provare a "ricostruire", attraverso le carte le immagini, la storia complessa e stratificata dei ponti siciliani, interpretandone le vicende progettuali e costruttive anche in relazione al più ampio dibattito che ha animato il mondo scientifico europeo, in particolar modo tra XVII e XIX secolo.
Indagini briologiche in aree urbane: diversità briofitica dei centri abitati di Erice (Trapani) e Belmonte Mezzagno (Palermo).
2017
Bryologic surveys in urban areas: bryophyte diversity of the population centers of Erice (province of Trapani) and Belmonte Mezzagno ((province of Palermo). The bryophytic flora of the towns of Erice (Trapani) and Belmonte Mezzagno (Palermo) have been studied. The first consists of 53 taxa (42 mosses and 11 liverwort), two of which are new for the province of Trapani, the second of 40 taxa (38 mosses and 2 liverworts), one of which new for the province of Palermo. A comparison between the studied bryofloras and those of other Sicilian urban areas shows that Erice’s bryophytic flora is, given its size, rich in species and families.

Seasonal variation in total phenolic content of Dictyopteris polypodioides (Dictyotaceae) and Cystoseira amentacea (Sargassaceae) from the Sicilian c…
2014
This study focuses on the differences in total phenolic content and its seasonal variations in two temperate brown algae, Cystoseira amentacea (C. Agardh) Bory and Dictyopteris polypodioides (A.P. De Candolle) J.V. Lamouroux, inhabiting respectively the infralittoral fringe and the upper infralittoral zone. Phenolic compounds are secondary metabolites, found in almost all brown algal orders, that function as defense against grazers, epiphytes and UV radiation. Total phenolic content was determined colorimetrically with the Folin-Ciocalteu reagent. Results showed significant differences in total phenol content between D. polypodioides and C. amentacea with higher values observed in the first…
