What is a tree in the Mediterranean Basin hotspot? A critical analysis

2019

Background: Tree species represent 20% of the vascular plant species worldwide and they play a crucial role in the global functioning of the biosphere. The Mediterranean Basin is one of the 36 world biodiversity hotspots, and it is estimated that forests covered 82% of the landscape before the first human impacts, thousands of years ago. However, the spatial distribution of the Mediterranean biodiversity is still imperfectly known, and a focus on tree species constitutes a key issue for understanding forest functioning and develop conservation strategies. Methods: We provide the first comprehensive checklist of all native tree taxa (species and subspecies) present in the Mediterranean-Europ…

Soil erosion assessment on tillage and alternative soil managements in a Sicilian vineyard

2011

Mediterranean crops favour high erosion rates. Vineyards use to reach the highest soil and water losses due to the lack of vegetation cover. A topographical approach by means of the use of vineyards poles as fixed reference point as erosion markers allowed to quantify high and non-sustainable soil erosion rates on the Sicilian vineyards during 9 years. In order to develop strategies to control the soil losses, seven land management were selected and applied in a typical blanc wine grape vineyard located in southwestern Sicily. Comparable plots were managed traditionally using conventional tillage and alternatively using various cover crops: 1) Vicia faba; 2) Vicia faba and Vicia sativa; 3) …

Deep stratosphere-to-troposphere transport (STT) over SE Europe: a complex case study captured by enhanced <sup>7</sup>Be…

2005

Abstract. In this study we present a complex case study of a Stratosphere-to-Troposphere Transport (STT) event down to the surface of a low topography region in Northern Greece, during the second fortnight of March 2000. During this event our surface station at Livadi (23°15 E/40°32 N, 850 m a.s.l.), was influenced by very different synoptic systems developing over Eastern Europe, N. America and the N. Atlantic, the last one evolving to a cut-off low over France/Spain. This is the first study, to our knowledge, that presents a down to the surface STT event in the eastern Mediterranean. The intrusion is primarily captured with the use of the cosmogenic radionuclide 7Be, which increased to 9.…

ASSESSING SPREADABILITY OF WARM SEASON SPECIES USED FOR TURFGRASS ON THREE TYPES OF SUBSTRATE IN THE MEDITERRANEAN ENVIRONMENT

2014

The aim of the study was to examine the performance of turfgrass warm season species, including 6 varieties of Cynodon dactylon in comparison with Zoysia japonica and Paspalum vaginatum in three substrates with different soil textures (sandy loam, sandy clay loam, clay), to find the one or the ones that adapt best in the Mediterranean environment. The results showed the best perfomances in sandy loam substrate and for C.dactylon cv. Transcontinental, Capriola and La Paloma. Z. japonica, Zenith, had lower values.

Lina Bo Bardi: Unbuilt in Sicily

2017

In August 1940 the magazine ‘Domus’, in a special issue dedicated to the “casa al mare”, publishes the project of the “Casa sul mare di Sicilia” by Lina Bo Bardi and Carlo Pagani. It is one of the first projects of Lina Bo, an utopian project whose representations indicate a way of proceedings that coagulates theory and imagination conceived as indissoluble relationship of “doing”. Add to the ‘unconventional’ drawings of the project, plans, perspectives and perspective section, indicating a very personal way in using of graphic language, we can find a synthesis’ drawing that underlines how the representation is intended both as an extension of the mind, and as order structure of a speech. I…

ENTE REGIONALE PER IL DIRITTO ALLO STUDIO (ERSU): MENSE GOURMET?

2015

Introduzione: Abitudini alimentari poco sane hanno ricadute negative sulla salute pubblica. Il servizio di ristorazione universitario è diventato protagonista della salute e del benessere collettivo di studenti e lavoratori. In conseguenza a ciò nasce la necessità di acquisire informazioni sulla popolazione che usufruisce delle mense al fine di costruirne il profilo di salute e cercare di migliorarlo. Metodi: È stata condotta una survey su un campione di utenti delle mense dell’ERSU di Palermo, tramite somministrazione di un questionario con lo scopo di valutare il consumo alimentare secondo il modello della dieta mediterranea (DM). È stato ideato uno score di aderenza (SA) alla piramide de…

Vegetation dynamics within afforested coastal areas: regeneration by native species or invasion by alien species?

2017

During the last century, massive reforestation projects along the dunes of the southern Sicily have been carried out. Such interventions, far from being in line with the current trends of close-to-nature silviculture, are, however, particularly interesting to assess the vegetation dynamics in afforestation areas. Furthermore, these kind of interventions may determine two opposite effects, that is renaturalization by native woody species or invasion by alien species. Acacia spp. are among the most widespread and prominent invaders within Mediterranean-climate areas, where they have already shown the capability to deeply change the characters and the functioning of native ecosystems. For inst…
