The decline of the cork oak growing in Sicily is accompanied by the loss of the functions proper to agroforestry systems
2021
The cork oak is one of the most important tree species in the Mediterranean basin, where it covers more than 2 million hectares. Among evergreen oaks, Quercus suber stands out for the variety of cultural systems in which it has been successfully employed, including typical agroforestry systems. Accordingly, a wide range of ecosystem services may be associated to cork oak, including the preservation of biodiversity, carbon sequestration and forage production. In the Mediterranean, the cork oak represents a key species for many natural and seminatural landscapes and habitats, as well as playing a prominent role for the economic and social development of local communities. However, there is in…
Profilo dell'attività scientifica di Fabiola Ardizzone
2018
Si ripercorre l'attività scientifica della compianta Collega Fabiola Ardizzone, dai suoi esordi come allieva della Cattedra di Archeologia Cristiana dell'Università di Palermo, all'attività di insegnamento e di ricerca sul campo in qualità di Professore Associato. Il contributo dato da Fabiola Ardizzone agli studi sulla Tarda Antichità e sul Medioevo siciliani hanno riguardato molteplici direttrici di ricerca: dall'identificazione di nuove classi ceramiche alle modalità di organizzazione delle aree funerarie, dai problemi di topografia urbana all'archeologia dei cimiteri e ai problemi della produzione e circolazione delle produzioni ceramiche. The paper traces the scientific activity of Fab…
Propagation of Calendula maritima Guss. (Asteraceae) through Biotechnological Techniques for Possible Usage in Phytotherapy
2022
The genus Calendula (Asteraceae) includes several species that are renowned for their therapeutic properties and/or use as ingredients in the preparation of cosmetics. The rare and critically endangered sea marigold, Calendula maritima Guss., an endemic species from Western Sicily, has also been recognized as a potential “farm plant species” for several important compounds used in cosmetics. However, the few remnant populations of this species are currently threatened with extinction because of several factors, such as hybridization with the congeneric species Calendula suffruticosa subsp. fulgida (Raf.) Guadagno and anthropogenic disturbance of its habitat. Therefore, in order to preserve …
Tiburones de aguas profundas en el Mioceno medio de Alicante: implicaciones para la recuperación de los ecosistemas abisales mediterráneos después de…
2017
El estudio de la localidad clásica de El Chorrillo del Mioceno Medio (Serravaliense) en la Provincia de Alicante, ha permitido la recuperación de una interesante asociación de microrestos de tiburones caracterizada por al menos siete taxones (Deania calcea, ¿Isistius triangulus, ¿Squaliolus cf. schaubi, ¿Paraetmopterus sp., Pristiophorus sp., Scyliorhinus sp. y un Squaliforme indeterminado) pertenecientes a tres órdenes diferentes (Squaliformes, Pristiophoriformes y Carcharhiniformes). Asociados a estos microrestos se han identificado también macrodientes pertenecientes a Cosmopolitodus hastalis, Isurus sp., Hemipristis serra, Odontaspis sp., Carcharhinus spp. y ¿Otodus (Megaselachus) megal…
The recent spread of the invasive woody alien plant Melia azedarach L. (Meliaceae) in Sicily
2013
This paper aims at reporting the ongoing process of naturalization of Melia azedarach L. in Sicily. In fact, over half a century after the first detection of spontaneous self-sown seedlings, an abrupt increase of naturalization cases has been recorded by the authors during the last twenty years. More in detail, M. azedarach successfully colonized many suburban lowland areas along the coasts of the island which are characterised by thermo-Mediterranean bioclimate. According to both field and literature data, a gradual spread of M. azedarach in the island can be expected, although it is not possible to predict the speed with which this will occur. Historical information on its introduction at…
Acacia cyclops A. Cunn. ex G. Don (Leguminosae) in Italy: first cases of naturalization
2012
The first two cases of naturalization of Acacia cyclops are reported for Italy. Young trees were observed growing in the wild some 15 years ago on Linosa (Pelagie Islands, Strait of Sicily). A decade later, this alien plant should no longer be considered as a casual, since a very intensive process of self-sown regeneration has been observed in some plantations on Lampedusa, the major island of the same Archipelago. The available literature suggests the need for careful monitoring of the ongoing invasion process, as A. cyclops has already shown a very invasive behaviour elsewhere within Mediterranean-type biomes due to its ability to withstand high environmental stresses. As migrating birds …

Amphipod assemblage under the influence of desalination plants in the south-eastern Mediterranean
2019
A check-list of amphipod assemblage, collected in the vicinity of two Israeli desalination plant marine outfalls, is provided with some notes about the species. The dataset highlights changes in species composition throughout the years, possibly due to local anthropogenic impacts.
Protection by extra virgin olive oil against oxidative stress in vitro and in vivo. Chemical and biological studies on the health benefits due to a m…
2017
Abstract We report the results of in vivo studies in Caenorhabditis elegans nematodes in which addition of extra virgin olive oil (EVOO) to their diet significantly increased their life span with respect to the control group. Furthermore, when nematodes were exposed to the pesticide paraquat, they started to die after two days, but after the addition of EVOO to their diet, both survival percentage and lifespans of paraquat-exposed nematodes increased. Since paraquat is associated with superoxide radical production, a test for scavenging this radical was performed using cyclovoltammetry and the EVOO efficiently scavenged the superoxide. Thus, a linear correlation (y = -0.0838x +19.73, regres…
Metabolites from Mediterranean plants: characterization and transformation. Chemotaxonomic assessment and biological activity.
Questo progetto di ricerca ha lo scopo di ampliare le conoscenze di alcune piante appartenenti alla flora Mediterranea. Le piante da studiare sono state scelte in seguito ad un’attenta analisi bibliografica tra specie poco sudiate. La scelta è quindi ricaduta su nove specie appartenenti al genere Anthemis, due specie appartenenti al genere Pulicaria e sulle specie di Tetraclinis articulata, Salvia argentea, Ajuga tenorei, Ballota hispanica, Moluccella Spinosa e Thapsia garganica. Di esse sono stati preparati ed identificati i componenti degli oli essenziali e successivamente effettuati su di essi i saggi antibatterici. Dagli estratti delle specie di Tetraclinis articulata e Ajuga tenorei so…
