Variazione degli stock di carbonio del suolo in seguito ai processi di abbandono dei coltivi: il caso studio dell’isola di Pantelleria (TP)
2007
The recent abandonment of marginal agricultural areas in the Mediterranean has caused an increase of the surface occupied by pre-forest and forest formations. In order to study the carbon accumulation processes on Pantelleria Island was selected a North-facing area. This area includes 5 stages of succession (sds) that compose a chronosequence (from 0 to 30 years) to understand soil C accumulation processes after abandonment. These are abandoned vineyards or caperbushes, not disturbed (grazing, fire) since agricultural abandonment, and they are situated in thermomediterranean belt and on the same parent material and consequently considered in the same ecological conditions. Samples at 1 cm, …
Primi dati sugli alberi monumentali di Pantelleria
2016
Poche o nulla sono le informazioni sugli alberi monumentali delle piccole isole che circondano la Sicilia. Ciò è dovuto innanzitutto alla rarità di alberi definibili monumentali, le piccole isole hanno subito infatti una trasformazione ancora più profonda della Sicilia, ma anche ad un difetto di conoscenza. Il nostro vuole essere un primo contributo alla conoscenza degli alberi monumentali nell’isola di Pantelleria. Gli alberi censiti appartengono a due specie, il pino marittimo (Pinus pinaster subsp. hamiltonii) e il leccio (Quercus ilex). In realtà nel caso del pino marittimo possiamo parlare di un “popolamento monumentale” corrispondente alla pineta a pino marittimo presso la località Mo…
Demographic, Genealogical and morphological characterization of Pantelleria donkey
2004
A demographic, genetic and morphological evaluation on Pantelleria donkey's population was carried out to give a contribution for the exploitation of this old donkey breed. Genealogical data were analysed by the software Minbreed v 1.0. Pedigree is composed by 4 generations. The inbreeding of the population (Fwhole population = 0.4 %) resulted very low than the expectations; therefore, the inbreeding coefficients resulted low in the males F male, = 0.9 % and in the females Ffemale = 0.0 %. On the other hand, the mean relationship among the 378 couplings resulted very high a1j = 15,1 %. The morphological study was carried out on 20 subjects. For each animal the most important morphologic…

Melt inclusion study on the pantelleritic plinian eruption of the Green Tuff, Pantelleria Island.
2012
Pantelleria Island is the type locality for the peralkaline rhyolitic rocks called pantellerites. In the last 50 ka, after the Plinian, caldera-forming, Green Tuff eruption, volcanic activity at Pantelleria consisted of effusive and mildly explosive eruptions which mostly vented inside and along the rim of the caldera producing silicic lava flows, lava domes and poorly dispersed pantelleritic pumice fall deposits. During the last two decades, a wealth of studies focused on melt inclusions in pantellerite magmas, all converging in underlying the H2O-rich character of these melts together with high contents of halogens. Recent study on the volatile content of pantellerites from Pantelleria yi…
Geology and petrochemistry of recent (25 ka) silicic volcanism at Pantelleria Island
2007
built a complex sequence of interfingered deposits emitted by closely spaced eruptive vents which are frequently associated with dome-building phases and pantelleritic lavas flows. Field relationships allowed us to recognize eight eruptive units, all lying above the Montagna Grande trachytes. As a whole, petrochemical characteristics of the erupted products indicate an evolutionary trend in which Na-clinopyroxene was the liquidus phase, followed by alkali feldspar. Amphibole and quartz are late-crystallizing, whereas aenigmatite is both early- and late-crystallizing as well. Aenigmatite and Na-clinopyroxene crystallization buffers efficiently the increase of agpaicity, induced by feldspar c…
ANFORE E CERAMICHE COMUNI E DA FUOCO DA THERMAE HIMERAEAE (SICILIA) E DAL SUO HINTERLAND
2014
This report, part of a wider project involving the ancient landscapes of Himera and Thermae, presents the archaeological and archaeometric results on Late Roman amphorae and coarse/cooking wares from Termini Imerese. The aim is also to illustrate the distribution of the same types of Roman pottery in the hinterland of Thermae, where the Dept. of Cultural Heritage of Palermo University has carried out intensive surveys (from 1982, published from 1988 until 2009). A good documentation of African amphorae, coarse/cooking wares, produced both in Byzacena and Zeugitana, and also local amphorae and coarse/cooking wares and Pantellerian ware, have been found both in Thermae and in the hinterland, …
La diversità degli animali domestici nelle isole circumsiciliane: un patrimonio scomparso prima di essere conosciuto
2018
In tutti gli studi che affrontano il tema della perdita della diversità animale allevata e vegetale coltivata in Sicilia non si fa cenno alla presenza di razze animali nelle isole circumsiciliane, ad eccezione dell’asino di Pantelleria. Recenti indagini hanno permesso di accertare una presenza storica, seppur limitata, di razze animali, oggi estinte, sulle isole parasicule. Inoltre i testi che trattano specificatamente di tali razze forniscono preziose informazioni sul passato uso agro-pastorale dei territori insulari e meritano pertanto un’adeguata valorizzazione. None of the studies dealing with the loss of Sicilian reared animal and cultivated plant diversity mentions the presence of ani…
