Invasive Aliens in Italy: Enumeration, History, Biology and Their Impact
2021
Italy includes two large islands, Sardinia and Sicily, and a peninsula separated from the European continent by the Alpine Arch. At national level ISPRA (Instituto Superiore per la Protezione e la Ricerca Ambientale, Higher Institute for Environmental protection and research) is the instrument of the Ministry of Environment and for the Protection of the Territory and the Sea to carry out its mission, including the study, monitoring, and control of invasive alien species. Universities, Scientific Societies, and ONGs play a vital role in basic research. The interest in the study of alien plants is of a theoretical nature, as regards the migrations of living beings and interactions with native…
The alien vascular flora of Stromboli and Vulcano (Aeolian Islands, Italy)
2021
The updated censuses of the alien flora of the islands of Stromboli and Vulcano, Aeolian Islands in the Central Tyrrhenian Sea, are presented here. They currently consist of 40 and 57 specific and subspecific taxa respectively. As many as 16 and 18 taxa respectively are new in comparison with the last censuses in 2016. Mesembryanthemum × vascosilvae, commonly cultivated in both islands, is reported for the first time as naturalized alien to Italy. Passiflora incarnata from Stromboli and Pelargonium graveolens from Vulcano are reported for the first time as casual aliens to Sicily. The evolution over time of these florulas, as inferred from the main floristic works published on these islands…

Inventory of the non‐native flora of Italy
2009
In this paper we present a comprehensive inventory of the non‐native vascular flora of Italy, which was produced within the project “A survey of the Italian non‐native flora”, funded by the Italian Ministry for the Environment. Previously published floristic accounts were the main source of information. Historical records were critically revised and integrated with recent literature, data from herbaria and some unpublished information, so as to obtain a complete, up‐to‐date catalogue of the non‐native vascular plant species that occur spontaneously in Italy. The inventory lists 1023 non‐native species and subspecies, which account for 13.4% of all the Italian flora. The Italian non‐native f…

First record of Sphaeralcea bonariensis (Cav.) Griseb. (Malvaceae) as a casual alien species in the Mediterranean area
2022
Sphaeralcea bonariensis (Cav.) Griseb. is here reported for the first time as alien species in Italy and in the Mediterranean area. It is a perennial shrub native to Southern America, where it is often considered a ruderal species frequent in cultivated areas. It was found in a population of a few individuals within Opuntia ficus-indica groves of Rocca Palumba territory (Western Sicily). Actually, due to short-term observational period and the low number of plants, Sphaeralcea bonariensis should be considered as a casual species in Italy. The ecological characteristics of the growing stand and the consistency of the population, as well as the possible causes of its introduction, are briefly…
