Human activities trigger change in marine landscape
2018
Biodiversity is undergoing rapid and worrying changes, partially driven by anthropogenic activities. Human impacts and climate change (e.g. increasing temperature and ocean acidification), which act at different spatial scale, represent the most serious threats to biodiversity and ecosystem structure and function. In this overview, the effects of anthropogenic pressures on unique and valuable Mediterranean systems, such as Cystoseira sp. pl. forest and Posidonia oceanica meadows, are examined. These complex systems, characterized by a high associated biodiversity, are regularly exposed to natural and anthropogenic pressures. Due to the central role they have for several important ecological…
La biodiversità fungina in ecosistemi forestali in presenza e assenza di attività selvicolturali
Nell’ambito dell’attività formativa di dottorato, mi sono occupato della relazione esistente tra la presenza e il ruolo dei funghi, della flora vascolare, dei licheni e dei muschi, con la forma di governo del bosco, in ecosistemi complessi, quali le foreste urbane. Analizzando, in dettaglio, come la gestione del bosco tende ad influire direttamente sulle dinamiche delle cenosi fungine e sulla presenza/assenza delle singole entità. Lo studio, svolto all’interno di un popolamento forestale artificiale ad Eucalyptus camaldulensis, in un popolamento forestale artificiale a Pinus sp. pl. e all’interno di un popolamento forestale artificiale con elementi di naturalità, scelta derivante dalla loro…
Implementation of an online information system for the “Flora Critica d’Italia”
2015
Since the early 2000s, within the Italian Botanical Society was discussed the opportunity to realize collaboratively a modern Flora articulated in monographs on the model of others under construction or recently completed in several European countries (1). This initiative had a milestone in 2007 with the institution of the “Fondazione per la Flora Italiana”, with the aim of supporting the activities of study, conservation and cultural and scientific enhancement of the flora of Italy and of sensitizing the national community about the many functions that it implements, in the context of natural and semi-natural ecosystems. The “Foundation for the Italian flora” is responsible for the publica…
The changing role of botanic gardens in the Mediterranean
2016
Born as medicinal plant gardens (Gardens of Simples, Giardini dei semplici), for the cultivation and study of medicinal plants and the use their active principles, very soon, botanical gardens adapted themselves to the emerging needs of changing societies, expanding their activities towards new goals.

Seed germination reports for five species of the genus Silene (Caryophyllaceae)
2022
In this contribution, new germination data for five Silene taxa coming from the natural habitats of Sicily and Calabria are given. The investigated taxa are: the threatened endemic S. calabra and S. crassiuscula, together with S. colorata, S. fruticosa, and S. nicaeensis from Sicilian sites. Seed germinations were tested at the Catania Germplasm Bank (BGS-CT), at constant temperatures (from 5 to 30°C), under both light (12/12h photoperiod) and total darkness conditions. The results emphasized a high germination ability and rate in all examined species.
Strategie di gestione delle popolazioni di Calendula maritima Guss. (Asteraceae)
2011
Dopo avere brevemente esaminato la situazione in cui si trovano le popolazioni naturali di C. maritima, specie rara ed endemica della provincia di Trapani (Sicilia), si discute delle più opportune strategie di gestione al fine di assicurarne la conservazione. Vengono infine identificate le principali minacce e proposte le conseguenti necessarie azioni di tutela.
