Mujer, poder político y democracia paritaria. “Mujer y representación política institucional en la Comunidad Valenciana. 1977-1995. 2 parte. En esta segunda parte se recogen las mujeres que han formado parte de la Administración Local (alcaldesas, diputadas provinciales y FVMP), en los sindicatos, asi como en otras instituciones: Consell Valencià de Cultura, Consejo de Radiotelevisión Valenciana, Sindicatura de Agravios, Academia Valenciana de la Lengua, universidades, direcciones de partidos políticos, y otras organizaciones de la Comunidad Valenciana. “Mujer y representación política institucional en la Comunidad Valenciana. 1977-1995. Diputadas, ministras y cargos institucionales” es la …
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 …
Collating evidence on the restoration efforts of the seagrass Posidonia oceanica: current knowledge and gaps
2022
Seagrass meadows are important shallow coastal ecosystems due to their contribution to enhancing biodiversity, nu-trient cycling, carbon burial, and sediment stabilisation, but the maintenance of their integrity has been threatened by several anthropogenic disturbances. Active restoration is considered a reliable strategy to enhance recovery of seagrass ecosystems, and decision making for correct seagrass restoration management requires relying on valuable informa-tion regarding the effectiveness of past restoration actions and experimental efforts.Previous experimental efforts and human-mediated active restoration actions of the slow growing seagrass Posidonia oceanica have been collated h…
La Sicilia nell’area euro-mediterranea: radici antiche di un ponte culturale ed economico ancora attuale
2020
Nel Dipartimento di Architettura dell’Università di Palermo durante l’ultimo decennio sono state sviluppate alcune attività di ricerca nell’ambito della cooperazione transfrontaliera Italia-Tunisia, programma europeo i cui obiettivi sono ben riassunti dal motto Défis communs, objectifs partagés (Sfide comuni, obiettivi condivisi). Il programma ha fornito, principalmente a partner con sede nelle province della costa sud della Sicilia e di quella nord della Tunisia, l’occasione per lavorare congiuntamente sui molti temi di interesse comune. Il contributo riporta una sintesi delle attività svolte e un cenno a quelle proposte per la nuova programmazione, dopo aver presentato alcune considerazio…
Distribution of clay minerals in Early Jurassic Peritethyan seas: palaeoclimatic significance inferred from multiproxy comparisons.
2009
13 pages; International audience; A set of published, unpublished, and new clay mineral data from 60 European and Mediterranean localities allows us to test the reliability of clay minerals as palaeoclimatic proxies for the Pliensbachian–Toarcian period (Early Jurassic) by reconstructing spatial and temporal variations of detrital fluxes at the ammonite biochronozone resolution. In order to discuss their palaeoclimatic meaning, a compilation of low-latitude belemnite δ18O, δ13C, Mg/Ca, and 87Sr/86Sr values is presented for the first time for the whole Pliensbachian– Toarcian period. Once diagenetic and authigenic biases have been identified and ruled out, kaolinite content variation is cons…

Desalination effluents and the establishment of the non-indigenous skeleton shrimp Paracaprella pusilla Mayer, 1890 in the south -eastern Mediterrane…
2019
A decade long monitoring programme has revealed a flourishing population of the non-indigenous skeleton shrimp Paracaprella pusilla in the vicinity of outfalls of desalination plants off the Mediterranean coast of Israel. The first specimens were collected in 2010, thus predating all previously published records of this species in the Mediterranean Sea. A decade-long disturbance regime related to the construction and operation of the plants may have had a critical role in driving the population growth. University of Palermo FFR 2018
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.
