Su mortu mortu vs Halloween. Questue infantili in Sardegna

2020

Il contributo indaga il rapporto fra questue infantili tradizionali e Halloween in Sardegna. Dalle ricerche sul campo è emerso che in diversi centri Halloween è subentrato ai giri di raccolta consuetudinari, in altri convive con essi, ma nella maggior parte dei paesi il festival di origine anglosassone non si è ancora diffuso poiché, appunto, sono vitali le questue tradizionali. Si tratta di due manifestazioni rituali diverse, espressione di contesti storici e socioculturali ma anche politico-economici differenti e tuttavia i simboli rituali più noti della “carnevalata americana" – la zucca con la candela accesa, la formula rituale per la richiesta dei doni e la minaccia di ritorsioni per l…

Active deformation in southern Italy from gnss velocities: updated results of the PTGA network

2010

Active deformation in Southern Italy, Sicily and southern Sardinia from GPS velocities of the Peri-Tyrrhenian Geodetic Array (PTGA)

2008

Campaign measurement (1995-2000) of Global Positioning System (GPS) site velocities in southern Italy, Central Mediterranean area, document differential displacements within the orogens rimming the Tyrrhenian Sea. Within the Southern Apennines, GPS velocities define two laterally juxtaposed belts of deformation, with transpression in the east and transtension in the west. In the east, ~8 mm/yr convergence between northern Murge-Gargano block and the International GPS System (IGS) site MATE is partitioned across ~east-west striking right-lateral faults, consistent with seismicity and with the offshore geological record. To the south, in northern Calabria, site velocities relative to MATE ind…

The lamellicorn beetles of southern Sardinia (Coleoptera: Scarabaeoidea)

2011

A faunistic inventory of lamellicorn beetles has been conducted in southern Sardinia (former province of Cagliari) based on literature and collection records, as well as on new fi ndings from recent fi eld expeditions (2003–2008). The taxonomic analysis of the study area revealed the occurrence of 105 species (2 Lucanidae, 2 Trogidae, 7 Geotrupidae, 1 Hybosoridae and 93 Scarabaeidae). The majority of families are represented by 100% of the known Sardinian fauna; o nly the Scarabaeidae, the most diverse family, is represented by 80.8% of its Sardinian members. Some considerations are made on the conservation status, trophic categories, chorotypes, habitat distribution and seasonal activity o…

A new voice from Sardinia: Uromenus annae (Targioni-Tozzetti, 1881 (Insecta: Orthoptera: Tettigoniidae: Bradyporinae: Ephippigerini)

2019

Recent findings of the Sardinian endemic Bushcricket Uromenus annae (Targioni Tozzetti, 1881) allowed the authors to retrace the nomenclatorial history of the species. The rearing of living specimens resulted in the recording of the male song, previously unknown. Since the Neotype previously established by Fontana & Buzzetti (2001) is lost, a new Neotype is here designated. Affinities with other congeneric species are discussed. 

Surveillance and control of African Swine Fever in free‐ranging pigs in Sardinia

2019

SUMMARY African swine fever (ASF) is a notifiable infectious disease, caused by the ASF virus (ASFV), which is a DNA virus belonging to the family Asfarviridae, genus Asfivirus. This disease has gained importance in the last decade after its spread in several countries in Eastern and Central Europe, and more recently, in China. Despite the efforts made to eradicate it, ASF is still present on the Mediterranean island of Sardinia (Italy) and has been since 1978. ASF risk factors on the island have been analysed in previous studies; the role of free‐ranging pigs in virus persistence has been suggested, but has not been fully elucidated. The most recent eradication plan provides more stringent…

8000 years of coastal changes on a western Mediterranean island: A multiproxy approach from the Posada plain of Sardinia

2018

Abstract A multi-proxy palaeoenvironmental investigation was conducted to reconstruct the Holocene history of coastal landscape change in the lower Posada coastal plain of eastern Sardinia. In the Mediterranean region, coastal modifications during the Holocene have been driven by a complex interplay between climate, geomorphological processes and human activity. In this paper, millennial-scale human-sea level-environment interactions are investigated near Posada, one of the largest coastal plains in eastern Sardinia. Biostratigraphic and palynological approaches were used to interpret the chrono-stratigraphy exhibited by a series of new cores taken from the coastal plain. This new study elu…

Floristic traits and biogeographic characterization of the Gennargentu massif (Sardinia)

2013

A study on the vascular flora of the Gennargentu Massif (Central-Eastern Sardinia) is presented. According to our results, the flora consists of 948 taxa: 686 species, 249 sub- species, 10 varieties and 3 hybrids, belonging to 97 families and 427 genera. Three taxa are new findings for the flora of Italy and eight for that of Sardinia. Life form analysis revealed, in particular, dominance of 35.65 % hemicryptophytes, 34.6 % therophytes, 12.13 % geophytes and 11.6 % (nano)-phanero- phytes. As concerns chorology, the Mediterranean element is largely prevailing (68.14%), mainly represented by circum- Medit. (29.1 %) and Euro-Medit. (23.07 %). Endemics are 14.87% of the whole flora (141 taxa), …

Strain analysis and vorticity of flow in the Northern Sardinian Variscan Belt: Recognition of a partitioned oblique deformation event

2008

Abstract A field example of strain partitioning has been analysed along the Nurra–Asinara transect of the NW Sardinian Variscan chain (Italy). The section in the Nurra–Asinara area is in a continuous sequence of tectono-metamorphic complexes made of low- to high-grade metamorphic rocks affected by a polyphase tectonic history. The principal fabric of the area is controlled by a D2 progressive deformation phase in which the strain is partitioned into folds and shear zone domains. The D2 stretching lineation and shear sense show a clear change from south to north. The principal meso- and micro-structures, vorticity gauges and a quantitative kinematic analysis of local strain suggest that the …

Mycobacterium tuberculosis molecular evolution in western Mediterranean Island of Sicily and Sardinia

2004

Abstract In this study, a total of 204 Mycobacterium tuberculosis DNAs from Sicily ( n = 144) and Sardinia ( n = 60) were studied by three genotyping methods. Results were analyzed both within and across islands, to define the phylogeographical specificities of the genotypes, look for their diversity and infer a molecular evolutionary scenario. A strong link between geography and tuberculosis genotypes was observed in Sardinia. The results were also matched against a world-wide genetic diversity database to compare the population structure of the tubercle bacilli in the islands. Eight common genotypes between Sicily, Sardinia and continental Italy were found which underlines the influences …
