Grapes and vines of the Phoenicians: morphometric analyses of pips from modern varieties and Iron Age archaeological sites in the Western Mediterrane…
2021
The present study aims to contribute to the investigation of the role of Phoenicians in the spreading and trade of the grapevine through the morphometric analysis of grape pips. Waterlogged and charred samples were selected from three Iron Age sites in the Western Mediterranean: Motya (Sicily, Italy), Nuraghe S’Urachi (Sardinia, Italy) and Huelva (Andalusia, Spain). While only Motya is a Phoenician foundation, all three were nevertheless associated with Phoenician expansion and cultural interaction. Ten cultivars from the “Vivaio Federico Paulsen” in Marsala (western Sicily) were chosen as modern reference material. The key challenge was the comparison of archaeological pips preserved throu…
Unusually large magmatic CO2gas emissions prior to a basaltic paroxysm
2010
[1] The low-intensity activity of basaltic volcanoes is occasionally interrupted by short-lived but energetic explosions which, whilst frequently observed, are amongst the most enigmatic volcanic events in Nature. The combination of poorly understood and deep, challenging to measure, source processes make such events currently impossible to forecast. Here we report increases in quiescent degassing CO2 emissions (>10,000 t/day) prior to a powerful explosive event on Stromboli volcano on 15 March 2007. We interpret such large CO2 flux as being sourced by passive gas leakage from a deeply (>4 km) stored magma, whose depressurization, possibly caused by the onset of an effusive eruption on 28 F…
New polymorphic microsatellite markers and development of mitotyping primers for West Mediterranean green toad species (Bufo viridis subgroup).
2009
We report new polymorphic microsatellites for three species of Palearctic green toads (Bufo viridis subgroup): 10 in B. balearicus and seven each in B. siculus and B. boulengeri. Diversity at these loci, measured for 27 B. balearicus, 23 B. siculus and 11 B. boulengeri, ranged from low to high (two to 10 alleles). Mitotyping primers, specific to the control region, which allow fast screening of parapatric Sicilian endemic B. siculus and Italian mainland-origin B. balearicus, were developed.
Hypericum scruglii sp. nov. (Guttiferae) from Sardinia
2010
A new species of Hypericum (Guttiferae) from Sardinia, H. scruglii, is described and illustrated. It occurs on damp soil, near springs or streams with freshwater, where it grows with numerous hygrophytes. This diploid species (2n � 16) belongs to the sect. Adenosepalum and is closely related to H. tomentosum, a species widespread in the west Mediterranean region. During field investigations in Sardinia, very peculiar populations of Hypericum L. were found occuring on damp soils and limited to calcareous substrates. These plants showed a close morphological and ecological relationship with H. tomentosum L., a species belonging to sect. Adenosepalum Spach. As emphasized by Robson (1996), the …
Isolation frequency and efficiency of mycoparasitic Pythium species in the West Mediterranean region of Turkey
2021
Abstract A total of 132 mycoparasitic Pythium isolates were obtained from the soil samples taken from fruit orchards, vegetable fields, carnation greenhouses, sugarbeet fields and cereal fields in the West Mediterranean region of Turkey. The Oomycetes were isolated by using; surface soil dilution plate, sclerotia bait and precolonised plate methods. Isolates were identified as P. acanthophoron, P. amasculinum, P. lycopersicum, P. oligandrum, P. periplocum and P. paroecandrum, according to their morphological and molecular characteristics. The most commonly isolated mycoparasitic species were P. amasculinum and P. lycopersicum. The majority of the mycoparasites came from soil samples taken f…
Human Y-chromosome variation in the Western Mediterranean area: Implications for the peopling of the region
2001
Y-chromosome variation was analyzed in a sample of 1127 males from the Western Mediterranean area by surveying 16 biallelic and 4 multiallelic sites. Some populations from Northeastern Europe and the Middle East were also studied for comparison. All Y-chromosome haplotypes were included in a parsimonious genealogic tree consisting of 17 haplogroups, several of which displayed distinct geographic specificities. One of the haplogroups, HG9.2, has some features that are compatible with a spread into Europe from the Near East during the Neolithic period. However, the current distribution of this haplogroup would suggest that the Neolithic gene pool had a major impact in the eastern and central …
New data on Protaetia (Potosia) Opaca (Coleoptera Cetoniidae) from Pantelleria island (Sicilian Channel, Italy)
2018
Gli autori segnalano la presenza di Protaetia (Potosia) opaca (Fabricius 1787) nell’isola di Pantelleria (Canale di Sicilia, Mediterraneo centrale, Italia). Essi inoltre forniscono ulteriori osservazioni tassonomiche, biologiche e sulla distrubuzione di questa specie. Protaetia (Potosia) opaca (Fabricius 1787) (Coleoptera Scarabaeoidea Cetoniidae) is here being reported for the first time from the island of Pantelleria (Sicilian Channel, Central Mediterranean Sea, Italy). Taxonomic, distribution and biological data on this species are presented.
L'Occidente nella concezione geografica di Diodoro Siculo
2021
In his first five Books of Historical Library Diodorus pays a particular attention to the lands of Atlantic Far West. Even if the historian does not show to be particularly interested in geographical descriptions and cartography, nevertheless he often portrays the background of mythical stories happening in western areas according to patterns which, in a sort of symmetrical correspondence, are similar to the historian’s representation of events involving the geographical areas of the Asian Far East. Diodorus has a “continuistic” view of the development of civilisation in all parts of the world known until then. The geography of the mythical past is fully consistent with that of Diodorus’ ow…
Soil gas prospection of He,222Rn and CO2: Vulcano Porto area, Aeolian Islands, Italy
1997
Abstract In March 1994, soil gases were sampled in the area of Vulcano Porto, on the island of Vulcano, using a grid of about 200 points/km 2 . Analysed gases were CO 2 , He and 222 Rn and, over a smaller area, H 2 S. Some of the samples were also analysed for the isotope composition of CO 2 C. Three anomalous CO 2 degassing areas were identified: Grotta dei Palizzi, the area near the Telephone Exchange, and the area near the beach fumaroles. The behaviour of He and 222 Rn is different in these 3 areas. The concentration of He is much lower than that of atmospheric He (down to −3950 ppb) in the isthmus, and only in the area near Grotta dei Palizzi does it have values significantly higher th…
