Genetic variability of the blue and red shrimp Aristeus antennatus in the Western Mediterranean Sea inferred by DNA microsatellite loci
2012
Genetic variation at eight microsatellite loci was studied in nine populations of the blue and red shrimp Aristeus antennatus to investigate whether distinct stocks are present in the Western Mediterranean Sea. A high level of gene flow and no evidence of genetic partitioning were discovered. No significant variation was found (FST = 0.00673, P-value = 0.067) even when shrimps from exploited and those from deep-water unexploited grounds were compared. No evidence of reduction or expansion of population size in the recent past was found, as indicated by the bottleneck and interlocus g-tests. Our results are consistent with previous studies using mitochondrial gene methods and allozymes, indi…
Forest nurseries and the National Recovery and Resilience Plan: the case of Sicily and Apulia (Italy)
2023
In Italy, the National Recovery and Resilience Plan (NRRP) foresees the planting of ca. 6.6 million trees to establish urban and peri-urban forests in 14 metropolitan cities. This ambitious project requires a significant number of native trees and shrubs, currently unavailable in Italian public and private nurseries. This survey analyzes the state of forest nurseries in two administrative regions of southern Italy, i.e. the “Filici” forest nursery (province of Agrigento, Sicily) and the Gargano Mountain Reclamation Consortium (province of Foggia, Apulia), to evaluate the adequacy of Sicilian and Apulian forest nurseries as potential sources of plant material to meet the requirements of the …
La Corona d'Aragona nel Mediterraneo orientale del Quattrocento
2008
Messa a punto sulla politica della Corona d'Araghona nel Mediterraneo orientale nella prima metà del 400. Si analizzano le non sempre consonanti spuinte della mercatura catalana e della monarchia, le relazioni fra politica di potenza dei sovrani aragonesi e esigenze diplomatiche legate alle relazioni con la consolidata potenza ottomana e con la Chiesa romana. Si rileva la forte differenza di atteggiamento della monarchia iberica rispetto alla politica delle città mercantili italiane. Si sottolinea la portata del fenomeno delle migrazioni greca e albanese verso la Sicilia e l'Italia meridionale in relazione alla politica militare di Alfonso V nell'area balcanica.

Multi‐specific small‐scale fisheries rely on few, locally essential, species: Evidence from a multi‐area study in the Mediterranean
2022
Achieving sound management of small-scale fisheries (SSFs) is globally recognized a key priority for sustaining livelihoods, local economies, social wealth and cultural heritage in coastal areas. The paucity of information on SSFs often prevents the proper assessment of different socio-ecological aspects, potentially leading to draw inappropriate conclusions and hampering the development and adoption of effective policies to foster SSF sustainability. To respond to the growing global call to assess these fisheries, we carried out a multi-disciplinary and data-rich assessment of SSFs at 11 areas in 6 Mediterranean EU countries, combining the analysis of 1292 SSF fishing operations and 149 se…
Creating Office Spaces in the Mediterranean. The importance of well-being, health and performance of office users
2018
Recent research has studied the influence of office buildings indoor environment quality (IEQ) on employees’ well-being, health and performance. However, it seems that it has not been explicitly explored what are the appropriate environmental conditions to different work patterns that coexist in these spaces. This paper presents results of an empirical research, based on the synchronized measurements of different IEQ parameters (i.e., noise, lighting and temperature), and well-being, health and performance of 71 employees in twelve office spaces in the Valencian Community along three periods, considering winter and summer conditions. Findings of the first winter period data, suggest the exi…
MOVIMENTI, FRONTIERE E FRATTURE MEDITERRANEE
2007
Dopo aver affrontato il problema di come definire il Mediterraneo, si cerca di delinearne la morfologia socio-economica, con particolare attenzione alla situazione demografica e alla situazione dei sistemi produttivi mediterranei e di riflettere anche sulle categorie sociologiche dello sviluppo applicate al bacino mediterraneo. Si affronta il tema delle migrazioni nel Mediterraneo e in un area poco esplorata di esso, il Medio Oriente. In particolare si cerca di mettere in luce le principali caratteristiche socio-economiche del mondo arabo islamico, spesso rappresentato, nel mondo occidentale, come se albergasse in una sorta di vuoto sociale. Si riflette anche sulla progressiva trasformazion…
Database Species-Area Relationships in Palaearctic Grasslands
2012
The Database Species-Area Relationships in Palaearctic Grasslands (GIVD ID EU-00-003) is an initiative of the European Dry Grassland Group (EDGG) and primarily functions as repository for all data sampled during the EDGG Research Expeditions. During these expeditions two types of highly standardised sampling of dry grassland vegetation in the Palaearctic realm are carried out: (i) nested-plot sampling on squares of 0.0001, 0.001, 0.01, 0.1, 1, 10, and 100 m2; (ii) additional normal releves of 10-m2 plots. For all plot sizes, the terricolous vascular plants, bryophytes, and lichens are recorded that are superficially present (shoot presence). Additionally, for all 10-m2 plots species cover i…
Cover crops effectiveness for soil erosion control in Sicilian vineyard
2009
In vineyards, which are very common in Mediterranean area, cover crops are becoming increasingly used to reduce soil erosion. Cover crops reduce runoff by increasing infiltration and increasing roughness and then reducing the ovelandflow velocity. The aim of the present study was to quantify soil and water losses under different soil managements systems on vineyards. The study site was a Sauvignon blanc winegrape vineyard located in Southwestern Sicily. Vineyards were managed both traditionally (conventional tillage) and alternative management using cover crops: 1) Vicia faba ; 2) Vicia faba and Vicia sativa; 3) Trifolium subterraneum, Lolium perenne, Festuca rubra; 4)Trifolium subterraneum…
No-Till Soil Organic Carbon Sequestration Patterns as Affected by Climate and Soil Erosion in the Arable Land of Mediterranean Europe
2022
No-tillage (NT) has been considered an agronomic tool to sequester soil organic carbon (SOC) and match the 4p1000 initiative requirements of conservative soil management. Recently, some doubts have emerged about the NT effect on SOC sequestration, often because observations and experimental data vary widely depending on climate and geographic characteristics. Therefore, a suitable SOC accounting method is needed that considers climate and morphology interactions. In this study, the yearly ratio between SOC in NT and conventional tillage (CT) (RRNT/CT) collected in a previous study for flat (96 samples) and sloping (44 samples) paired sites was used to map the overestimation of SOC sequestra…
