2019

The Lamarck’s name Buxus balearica is discussed and neotypified from a specimen preserved at MA collected in Mallorca (Balearic Islands, Spain). In addition, the lectotypes of B. longifolia and B. balearica f. granatensis, currently treated as two heterotypic synonyms of B. balearica, are designated from original material preserved at G-BOIS and MA, respectively

Cruise tourism effects on the mediterranean islands' economies

2009

Precedent studies show that cruises are able to generate daily visitors distributing additional expenditure for tourist destinations, giving new possibilities to support existing and future local economic activities. For Mediterranean islands, particularly related to this kind of tourism, the economic effects of cruise tourism seem to be different if compared with other territories, here defined as mainland. The aim of this paper is to analyze the effects of cruise tourism in the Mediterranean ports of call for insular and non insular territories. By focusing on Daily Cruise Visitors behaviour and by analyzing the passengers spending patterns in this work, we evaluated the economic effects …

Yeasts vectored by migratory birds collected in the Mediterranean island of Ustica and description of Phaffomyces usticensis f.a. sp. nov., a new spe…

2014

Nine yeast species belonging to genera Candida , Cryptococcus , Phaffomyces , Rhodotorula and Wickerhamomyces , and one species of Aureobasidium genus were isolated from the cloaca of migratory birds. Candida glabrata and C. inconspicua were the species most frequently isolated and Wickerhamomyces sylviae , which has recently been described as a new species isolated from bird cloaca, was again found. The majority of isolates showed the ability to grow up to 40 °C and/or at pH 3.0, two environmental conditions typical of the digestive tract of birds. The phylogenetic analysis of the D1/D2 domain of 26S rRNA gene placed the cultures of Phaffomyces in a new lineage that differed from the close…

Downscaling climate change impacts, socio-economic implications and alternative adaptation pathways for islands and outermost regions

2021

Questo libro fornisce una panoramica completa degli scenari futuri del cambiamento climatico e delle problematiche di gestione associate all'impatto del cambiamento climatico sull'economia blu delle isole e delle regioni ultraperiferiche europee. La pubblicazione raccoglie i principali risultati dei risultati della ricerca del progetto Soclimpact, con l'obiettivo di aumentare la consapevolezza sociale tra i responsabili politici e l'industria sulle conseguenze dei cambiamenti climatici a livello locale e fornire informazioni basate sulla conoscenza nella progettazione delle politiche di sostegno, dal livello locale a quello nazionale. This book provides a comprehensive overview of the futur…

Origin of clay minerals in soils on pyroclastic deposits in the island of Lipari (Italy)

2005

The island of Lipari (Italy) is characterized by calc-alkaline to potassic volcanism and a Mediterranean-type climate. The mineralogical and chemical features of two different soil profiles with ages of 92,000 and 10,000–40,000 y, respectively, have been investigated. There were no Andisols, but Vitric and Vertic Cambisols have developed at both sites. Although the morphology of the soils was similar, remarkable differences in the clay mineralogy between the two sites were observed. The site with the Vitric Cambisol was associated with the weathering sequence: glass → halloysite → kaolinite or interstratified kaolinite-2:1 clay minerals. Both sites had smectite in the clay fraction and, to …

Recycled crustal carbon in the depleted mantle source of El Hierro volcano, Canary Islands

2021

The Canary Islands, in the eastern Atlantic, are among the most enigmatic Oceanic Island provinces on Earth, as the mantle source feeding its volcanism exhibits wide spatial heterogeneity and a multiplicity of sources. Multi-isotope whole-rock studies have long revealed the presence of a recycled oceanic crust/lithosphere component in the mantle source. However, noble gas systematics have been more challenging to interpret, and the available carbon isotope data is limited and cannot support/dismiss this interpretation. Here, we present the very first isotopic characterisation of CO2 and noble gases (He-Ne-Ar) in fluid inclusions (FI) in minerals hosted in mantle xenoliths from El Hierro, th…

THE MEDITERRANEAN AS SOURCE OF ORNAMENTAL

2013

Cultivation of plants for ornamental purposes throughout the Mediterranean dates back to deep antiquity. In fact Egyptian, Greek, Roman and other previous myths are pervaded with correlations among humans, gods and plants either useful or ornamental – whose names such as hyacinth, narcissus, and many others that are still common. In that period almost all of the ornamental flora was native to the Mediterranean and next countries, having been the flow from other territories irrelevant up to the Renaissance. From XVI century on, the whole Mediterranean ornamental heritage was gradually spread throughout the new discovered territories, and from there a huge number of plants was introduced to M…

Why do results conflict regarding the prognostic value of the methylation status in colon cancers? The role of the preservation method.

2012

Abstract Background In colorectal carcinoma, extensive gene promoter hypermethylation is called the CpG island methylator phenotype (CIMP). Explaining why studies on CIMP and survival yield conflicting results is essential. Most experiments to measure DNA methylation rely on the sodium bisulfite conversion of unmethylated cytosines into uracils. No study has evaluated the performance of bisulfite conversion and methylation levels from matched cryo-preserved and Formalin-Fixed Paraffin Embedded (FFPE) samples using pyrosequencing. Methods Couples of matched cryo-preserved and FFPE samples from 40 colon adenocarcinomas were analyzed. Rates of bisulfite conversion and levels of methylation of …

Whole-epigenome analysis in multiple myeloma reveals DNA hypermethylation of B cell-specific enhancers

2015

Abstract Analyzing the DNA methylome of multiple myeloma (MM), a plasma cell neoplasm, by whole-genome bisulfite sequencing and high-density arrays, we observed regional DNA hypermethylation embedded in extensive global hypomethylation. In contrast to the widely reported DNA hypermethylation of promoter-associated CpG islands (CGIs) in cancer, hypermethylated sites in MM as compared to normal plasma cells were located outside CpG islands and were unexpectedly associated with intronic enhancer regions active in normal B cells. Both RNA-seq and in vitro reporter assays indicated that enhancer hypermethylation is globally associated with downregulation of its host genes. ChIP-seq and DNAseI-se…
