Alien flora of Europe: Species diversity, temporal trends, geographical patterns and research needs
2008
International audience; The paper provides the first estimate of the composition and structure of alien plants occurring in the wild in the European continent, based on the results of the DAISIE project (2004–2008), funded by the 6th Framework Programme of the European Union and aimed at “creating an inventory of invasive species that threaten European terrestrial, freshwater and marine environments”. The plant section of the DAISIE database is based on national checklists from 48 European countries/regions and Israel; for many of them the data were compiled during the project and for some countries DAISIE collected the first comprehensive checklists of alien species, based on primary data …
First record of Heptapleurum arboricola Hayata (Araliaceae) as a casual non-native woody plant in the Mediterranean area
2021
I report here the first record of Heptapleurum arboricola Hayata (syn. Schefflera arboricola (Hayata) Merr.) (Araliaceae) as a casual non-native plant throughout the Mediterranean area. I observed the natural regeneration in urban areas at Castellammare del Golfo, a small coastal town in north-west Sicily (Mediterranean Italy). Due to the lack of self-sustaining populations and the short-term observational period, Heptapleurum arboricola should be considered as a casual species according to the classification of non-native plants. The detection of early signs of naturalization of non-native plants is of crucial importance for the management and control of invasive species. The main abiotic …
Genealogia della normatività. La normatività come controllo
2018
In this paper I draw the outline of a psychological genealogy of normativity: an account of normativity as a complex neuro-psychological fact, entirely analysable in non-normative terms. As a first step, I introduce two of the main problems faced by the genealogical approach. I call the first one “Gibbard problem”: what kind of neuro-psychological state is normative judgment? I call the second one “irreducibility of normativity problem”: normative dynamics seem to be irreducible to causal dynamics. As a second step, I examine the “dual model” of the psychology of normative judgment developed by J. Haidt and J. Greene. I argue that the dual model is not able to solve the aforementioned probl…
Primo caso di naturalizzazione di Pinus canariensis C. Sm.(Pinaceae) per la Sicilia e prima stazione di Acacia cyclops G. Don (Fabaceae) sull’isola m…
2013
Nella Riserva Naturale Orientata “Foce del Fiume Platani” (Sicilia meridionale) sono stati registrati il primo caso di naturalizzazione di Pinus canariensis (Pinaceae) per il territorio regionale ed il primo di Acacia cyclops (Fabaceae) per l’isola maggiore. Vengono inoltre fornite informazioni supplementari sulla demografia e sulla distribuzione di entrambe le specie nei rimboschimenti dell’area protetta, nonché una previsione del loro grado di invasività alla luce dei dati scientifici già pubblicati. First case of naturalization of Pinus canariensis in Sicily and first population of Acacia cyclops on the main island. Both cases of naturalization have been recorded within the Nature Reserv…
Nicodemia madagascariensis(Lam.) R. Parker (Family Scrophulariaceae), a casual alien plant new to Italy
2016
In this note the authors report the first case of naturalization of the Malagasy smoke bush within Italian territory. Along with a description of the abiotic and biotic characteristics of the invaded site, the current demographic and dynamic trends of the detected population by means of growth-ring analysis was also assessed. Moreover, an overview on the history of its introduction in Europe is provided, underlining the key role played by the Mediterranean cities with respect to the acclimatization and spread of alien tropical and subtropical plants. Due to its low frequency under cultivation, the Malagasy smoke bush should not behave as an invader in the future; on the other hand, its abil…
Ecologia e distribuzione di Chamaerops humilis L. (Arecaceae) nella Sicilia nord-orientale
2014
I settori costieri e collinari della Sicilia nord-orientale e delle Eolie sono stati esplorati ai fini della raccolta di informazioni aggiornate sulla distribuzione dei popolamenti di palma nana e sulle caratteristiche ecologiche delle stazioni che li ospitano. I risultati delle indagini di campo sono stati integrati dalla verifica dei toponimi locali legati ai nomi dialettali della specie. Si con- ferma la totale assenza della palma nana lungo l’intero settore costiero dei Nebrodi. Dei nove popolamenti accertati, quattro si trovano alle Eolie, due sul versante ionico e tre sul versante tir- renico dei Peloritani; uno di questi ultimi, localizzato su Capo Calavà, risulta inedito. La conco- …
Handroanthus heptaphyllus (Bignoniaceae) in Sicily: a new casual alien to Italy and Europe
2018
Handroanthus heptaphyllus (Bignoniaceae) is an ornamental tree native to different regions of South America (Brazil, Argentina, Bolivia, and Paraguay). Here we report from Sicily the first case of natural regeneration in Europe.
PLUMBAGO AURICULATA LAM. (Plumbaginaceae) IN SICILIA OCCIDENTALE: NUOVI DATI SULLA SUA DIFFUSIONE COME ESOTICA CASUALE
2017
Plumbago auriculata Lam. (Plumbaginaceae) in western Sicily: new data on its spread as casual alien. In questa nota si fornisce un quadro aggiornato sui casi di naturalizzazione di Plumbago auriculata Lam. (Plumbaginaceae) nella Sicilia occidentale e sul suo status invasivo a livello nazionale ed internazionale. Questa xenofita viene segnalata per la prima volta in diverse aree delle province di Agrigento, Palermo e Trapani, dopo essere stata segnalata per la prima volta presso l'isola di Linosa, nell'arcipelago delle Pelagie.
Dracaena draco (Dracaenaceae) spontaneizzata a Palermo (Nord Sicilia)
2013
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.
