Seed germination reports for Sicilian endemic taxa of the genus Helichrysum (Asteraceae)
2021
In the present study, successful germination protocols for 11 different taxa of the genus Helichrysum native to Sicily are discussed. Eight of them are representative of strict endemic Sicilian taxa, 2 are Italian sub endemic and one, namely H. stoechas, is a widespread W Mediterranean species. Given the controversial taxonomic status and relationships of the Mediterranean Helichrysum, the taxonomic approach enhancing the existing diversity of Sicilian populations was herein adopted from current literature. First germination records are given for some of the investigated taxa.

Floristic, phenological and chorological differences in the annual vegetation of Sardinia.
2007
The therophytic flora of Sardinia has been split into four main groups, basing on the ecologic requirements of species. The following groups have been recognized: flora of dry entisoils, flora of periodically swampy or submerged entisoils, flora of coastal sites, flora of fields, road edges and human settlements. Either, most frequent or exclusive species were ascribed to each group. A species was considered “exclusive” when its relative frequency outside a given group was estimated ≤10%. Differences have been highlighted within the groups, dealing with chorology, growth form, flowering time, colour of flowers, pollination and seed dispersal strategies.
Discovery of plants and fungi with antibacterial activity against Propionibacterium acnes
2016
Acne vulgaris is a common skin disorder that affects >85% of teenagers. Propionibacterium acnes is implicated in its pathogenesis, and like many other bacteria, is subject to emerging trends in antibiotic resistance. Novel therapies are in high demand. The aim of this study was to identify new leads for future pre-clinical development from herbal skin remedies used in Italy. We screened a unique natural product library composed of extracts from medicinal and randomly collected plants and fungi from the Mediterranean for growth-inhibitory and anti-biofilm activity in P. acnes. Evaluation of 157 extracts from 10 fungi and 58 plants led to the identification of crude extracts from seven specie…
All hands on deck: An innovative approach to sustained and sustainable conservation funding for endangered plants and ecosystems
2022
The Red List Project (TRLP) was founded in 2018 as an NGO [501(c)(3)], dedicated to preventing the extinction of the world's most endangered plant species and to protecting biodiversity hotspots. This approach is highlighted by an ongoing partner ship between TRLP, independent fragrance house Baruti Perfumes and the University of Palermo, to prevent the extinction of the Viola ucriana Erben and Raimondo, critically endangered. This violet is restricted to the slopes of Mt Pizzuta in the Serre della Pizzuta Nature Reserve in Sicily (Italy), between 950 and 1300 m s.l.m., where it grows in xeric prairies and is threatened by factors partly related to human disturbance (e.g., fires, grazing, e…

Dracaena draco (Dracaenaceae), naturalized in Palermo (N Sicily). – Dracaena draco L., an evergreen tree from the Atlantic islands (Canary, Cape verde and Madera Islands) introduced in Sicily in the second half of the XIX Century as an ornamental plant, was found naturalized on the Mount Pellegrino slopes (Palermo). This new Sicilian finding, confirms, more than 20 years after the first record in the East Cost of Sicily, the naturalization of the species in Italy.
