ROLE OF SICILY AND CIRCUM-SICILIAN ISLANDS AS RECIPIENT AND DONOR AREA FOR ALIEN MARINE MACROPHYTES IN THE CENTRAL MEDITERRANEAN SEA
2017
The spread of alien species is an ongoing phenomenon which is widely recognized as a major threat to biodiversity at all levels. The particularly high rate of alien introductions to the Mediterranean Sea has been mainly fuelled by the opening of the Suez Canal, by shipping, aquaculture and by a rising trend in seawater temperature. As far as marine macrophytes are concerned, a total of 134 species have been listed as possible aliens in the Mediterranean Sea. Among the possible pathways of introduction, shipping is considered the dominant vector of unintentional species introduction in coastal marine systems worldwide. Traversing the Strait of Sicily, the chief passageway from south to north…

Mediterranean Gardens from Sicily to Malta
2012
This publication is one of the expected results of the European porject GARDMED (PO Italy- Malta 2007-2013). It aims to bring people to discover the Mediterranean gardens, highlighting the great botanical diversity, the history, the artistic, cultural and natural heritage.
Proposal to conserve the name Orobanche foetida (Orobanchaceae)
2015
In this Proposal we formally propose to conserve O. foetida with Bourgeau’s gathering of 16 April 1856 as conserved type. Our choice rests on the following reasons: (1) it clearly represents the current usage of the name O. foetida; (2) it is based upon material from northern Algeria not far from the Algerian-Tunisian border where the ranges of the two species overlap and in a region broadly coincident with the original terra classica of Poiret’s name; (3) the proposed conserved type is readily accessible online in a remarkably detailed digitization; (4) the sheet contains a sample of the host plant, which proves to be a non-shrubby Fabaceae (presumably Medicago laciniata (L.) Mill.) and th…
INVESTIGATION ON OLD-GROWTH FORESTS OF SICILY: PRELIMINARY RESULTS
2014
Old-growth forests are natural forests that have developed over a long period of time, without experiencing severe, stand-replacing disturbance a fire, windstorm, or logging. According to UNEP/CBD/SBSTTA definition, an old-growth forest is a primary or a secondary forest which has achieved an age at which structure and species normally associated with old primary forests of that type have sufficiently accumulated to act as a forest ecosystem distinct from any younger age class. In a thematic contribution to the National Biodiversity Strategy, the authors report the following definition of Italian old-growth forests: Forest in which human disturbance is absent or negligible, and in which nat…
Forest ecosystems in the Monti Sicani Park (Sicily)
2022
The authors analysed the forest ecosystems in the Monti Sicani Park (Sicily). In particular, the state of the natural and non-native forests in the Site of Community Interest (SCI ITA040005) - Monte Cammarata, Contrada Salaci, was evaluated in terms of distribution, evolution of forest dynamics and, silvicultural activities. The evolution of vegetation within two different forest plots are analysed and management strategies are proposed. The finding on Mount Cammarata of seedlings of Fagus sylvatica in the undergrowth of a conifer afforestation is noteworthy.
First record of Euphorbia graminea (Euphorbiaceae) in Italy
2016
Euphorbia graminea Jacq. (Euphorbiaceae), a species native from Central America through northern South America, from Northern Mexico to Peru, has been found naturalized near Palermo (Sicily). This is the first record for Italy and Europe
Pleurotus nebrodensis, a very special mushroom
2013
Verifica dei luoghi storici di raccolta di Pleurotus nebrodensis (Basidiomycota)ai fini di una valutazione dello stato del popolamento
2009
Nel 1902, Ferdinando Alfonso Spagna, direttore dell’Istituto Agrario Castelnuovo e redattore dei Nuovi Annali di Agricoltura Siciliana, è autore di una pubblicazione dal titolo “Dei funghi velenosi” (1) nella quale include un “elenco minuzioso dei funghi mangerecci più comuni” al fine di fornire indicazioni utili ai cercatori di funghi e per evitare i frequenti avvelenamenti che, a quel tempo, avevano causato numerose vittime in varie regioni d’Italia. Alfonso Spagna, tra le specie eduli e di buone proprietà organolettiche, segnala Pleurotus nebrodensis [sub: Agaricus nebrodensis Inz.], “fungo di eccellenti qualità”, noto localmente con il nome di “fungo di basilisco”. A differenza di Giuse…
