Metabolomic Study of Dactylis glomerata Growing on Aeolian Archipelago (Italy)

2022

The Aeolian Islands (Italy) are a volcanic archipelago in the Tyrrhenian Sea comprising seven main islands, among which are two active volcanoes. The peculiar geological features and the wide variety of environments and soils have an important impact on native plants, and in particular, the Aeolian populations of Dactylis glomerata (a perennial cool-season bunchgrass) exhibit remarkable phenotypic variability. Considering that environmental drivers also strongly affect the production of plant metabolites, this work aimed at comparing the metabolomic profiles of D. glomerata (leaves) harvested at different altitudes on four islands of the Aeolian archipelago, namely: Lipari, Vulcano, Strombo…

Une économie de la frontière : l’activité des femmes à Stromboli au XIXe siècle

2020

À Stromboli, pendant le XIXme siècle, les femmes étaient non seulement souvent propriétaires des maisons et des terres comme les hommes, mais aussi présentes dans tous les types de métier. Les témoignages des voyageurs et les sources historiques (actes notariés, enquetes) montrent qu’elles étaient actives dans l’agriculture, la pêche et le secteur maritime, le commerce et le petit crédit.

Women and movable goods in a maritime border economy in 19th century Sicily (Aeolian Islands)

2020

This chapter focuses on women possessing material goods, and on their informal administration, use, production, maintenance, and transformation in a small Sicilian island, Stromboli in the Aeolian Archipelago, in the first half of the 19th century. To explore this diverse social practices such as work, assistance, personal and familial relationships, and the informal management of money in transactions should all be taken into account. In areas such as Southern Italy, where Roman Law heritage predominated in Medieval and Early Modern age, women’s property rights were quite strong: although they were subject to special restrictions, they enjoyed, at the same time, special protections, as in …

The Eighth Island

2014

This paper proposes a succinct analysis of the factors that have led Aeolians to leave their islands for Australia and explores how patterns of chain migration were established in the second half of the 19th century that are still active today. Saija argues that initially Aeolians went to Australia out of a yearning for adventure rather than out of economic need, although after the substantial economic downturn experienced by the islands from 1888 onwards, economic need became the predominant if not the only factor. Over the last 150 years so many Aeolians have migrated to Australia that it has become known in the Aeolian collective consciousness as the eighth island of the Aeolian archipel…

Genetic diversity in Cytisus aeolicus Guss. (Leguminosae), a rare endemite of the Italian flora

1998

ABSTRACT Cytisus aeolicus Guss, is an endemic plant restricted to the isles of Vulcano, Stromboli and Alicudi in the Aeolian archipelago. All known populations were assayed for genetic variability using enzyme polymorphism. Allozyme variation at 16 loci coding for 10 enzyme systems was examined. The great majority of loci turned out to be monomorphic or fixed heterozygous. The observed genetic depauperation is indicative of historical factors, such as the bottleneck effect associated with migration, and the founder effect in population re-establishment. The low genetic diversity is largely partitioned within rather than among populations, indicating that extant populations have not been est…

Isolation and biodiversity inCytisus villosusPourret (Fabaceae, Genisteae): enzyme polymorphism in disjunct populations

1997

ABSTRACT The genetic diversity of isolated populations of Cytisus villosus has been studied by means of enzyme polymorphism analysis. Two types of isolated populations were studied: “terrestrial islands” in Sicily, and “true islands” in the Aeolian archipelago. In the populations of “true islands” the number of alleles and the heterozygosity are lower than in “terrestrial islands”. Isolation amongst Sicilian populations seems to be more recent than isolation of the Aeolian populations, and may be attributed to climatic changes which occurred during the Holocene and/or to human activities. The disjunction of the Aeolian populations seems much more recent than the origin of the isles themselv…

Volcano seismicity and ground deformation unveil the gravity-driven magma discharge dynamics of a volcanic eruption.

2015

Effusive eruptions are explained as the mechanism by which volcanoes restore the equilibrium perturbed by magma rising in a chamber deep in the crust. Seismic, ground deformation and topographic measurements are compared with effusion rate during the 2007 Stromboli eruption, drawing an eruptive scenario that shifts our attention from the interior of the crust to the surface. The eruption is modelled as a gravity-driven drainage of magma stored in the volcanic edifice with a minor contribution of magma supplied at a steady rate from a deep reservoir. Here we show that the discharge rate can be predicted by the contraction of the volcano edifice and that the very-long-period seismicity migrat…

Comparison of the effect of non-polluted and underwater-volcano-polluted seawater on the corrosion resistance of different stainless steels

2015

This work compares the effect of non‐polluted and underwater‐volcano‐polluted seawater on the electrochemical behavior of two different alloys, notably an austenitic stainless steel (SS) and a duplex stainless steel. Polarization measurements, potentiostatic passivation tests, electrochemical impedance spectroscopy and capacitance measurements were performed. Results show that the composition of the polluted seawater negatively affects the passivation kinetics of both AISI 316 SS and Alloy 900, decreasing the corrosion resistance of both alloys. Additionally, when both steels are compared, it can be concluded that passive films formed on Alloy 900 presented better protective properties than…

Piano di Gestione UNESCO Isole EOLIE

2008

Nel Piano di gestione del sito UNESCO Isole Eolie sono definiti i criteri e le modalità per realizzare contemporaneamente l’obiettivo della tutela di un bene e uno sviluppo locale sostenibile. Il Piano contiene una mappatura dei Beni Culturali e Ambientali e Naturalistici, descrivendo un sistema territorio sotto il profilo economico-ambientale che contiene: - L’inquadramento storico, economico e antropologico del sito, l’uso finora fatto, i fattori di incidenza sui beni ambientali e culturali; - L’inquadramento attuale del sito, attraverso un’analisi degli strumenti legislativi e amministrativi e della loro conformità; - L’analisi dei processi produttivi critici e le relative interazioni co…
