First assessment of natural regeneration and seed dispersal of Persian walnut (Juglans regia L.) in Mediterranean agroecosystems
2020
Persian walnut (Juglans regia L.), which is native to Central Asia, has been widely cultivated throughout Europe over millennia as a multipurpose tree. However, only recently the naturalization process outside cultivation has been studied, mostly in temperate Europe, with no information regarding the Mediterranean region. Here we provide the first field investigations about the natural regeneration of walnut in two traditional Mediterranean agroecosystems: an irrigated mixed orchard in suburban areas and a non-irrigated prickly pear (Opuntia ficusindica [L.] Mill.) orchard. The natural regeneration densities were statistically different in the two agroecosystems, ranging from 75 individuals…
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.
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.
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…
Brassica carinata (Cruciferae) spontaneizzata in Sicilia
2009
Brassica carinata (Cruciferae) naturalized in Sicily. Brassica carinata (Cruciferae) is reported occurring naturalized in Sicily. Two small populations of this taxon of hybrid origin, introduced in cultivation for production of combustible oilseeds in several countries of the Mediterranean region, including Sicily, have been found growing in hemerophilous conditions at the borders of the A.19 Palermo-Catania motorway, in locality Tremonzelli (Central Sicily).
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.
Pine stand density influences the regeneration of Acacia saligna (Labill.) H.L.Wendl. and native woody species in a mediterranean coastal pine planta…
2018
Mediterranean plantations are the most suitable areas to assess vegetation dynamics and competitive interactions between native and exotic woody species. Our research was carried out in a coastal pine plantation (Sicily) where renaturalization by native species (Pistacia lentiscus L. and Olea europaea var. sylvestris) and invasion by Acacia saligna (Labill.) H.L.Wendl. simultaneously occur. The regeneration pattern of woody species in the pine understory was evaluated in six experimental plots along a stand density gradient, from 200 to approximately 700 pines per hectare. Both pine stand density and regeneration by native species had a significant negative relationship with Acacia natural …
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…
Le specie alloctone invasive in Sicilia: caratterizzazione del fenomeno, strategie di colonizzazione e possibili strategie di contrasto

«Que en estos nuestros reinos llamábamos…»: a la búsqueda de una naturalización coeva de títulos y fórmulas de tratamiento en la traducción de la dra…
2019
La traducción de textos no-contemporáneos, ‘diacrónicos’, se puede plantear desde la lealtad romántica al original hasta la absoluta domesticación. Centrándonos en la onomástica de los títulos heredados y adquiridos y en las fórmulas de tratamiento, proponemos una naturalización histórica y cultural, de modo que la reacción del público ante la puesta en escena de la traducción sea lo más equivalente posible a la del público de la cultura de partida, hoy en día. La parte teórica arranca con la presentación y explicación de lo que entendemos como tres modos básicos de traslación, junto con la argumentación de nuestra propuesta metodológica. A continuación, se expone una taxonomía de títulos h…
