Abstract:

Recent research reveals what we term a ‘discourse of certainty’ regarding an assumed predominant socio-economic and cultural impact of Late Bronze Age Cypriotes or Mycenaeans on the local peoples of Sardinia and/or Sicily and Italy, not least in terms of a systematic, seaborne trading network extending from the Cyprus to the Tyrrhenian Sea. ‘Minimalist’ approaches to such a phenomenon have a long and venerable but more limited pedigree. In this study, we question why minimalist views have been so summarily dismissed in much current literature that seeks to evaluate an eastern Mediterranean presence or influence in the central Mediterranean. We focus on Sardinia, and on the range of Cypriot or ‘Cypriot-type’ materials found there. We consider the nature of the Cypriot–Sardinian relationship, and suggest that we should decouple foreign objects from foreign agents. We question several of the perceived Cypriot influences on Sardinian artefacts, and consider possible alternative mechanisms and routes of exchange between the east and central Mediterranean. We outline and discuss the array of presumed or actual Cypriot artefacts found on Sardinia, and argue that these do not add up to a ‘significant’ corpus of Late Cypriot materials and connections.

AbstractAbstract. The horseshoe snake (Coluber hippocrepis) is one of the most threatened Italian snakes, especially in Sardinia where its present occurrence was unclear. This paper reviews the current distribution of C. hippocrepis in Sardinia, and confirms that this species is still found in a limited number of sites of Cagliari province. Its actual presence in Oristano province, on the contrary, is still in doubt. Statistical analyses on several morphometric measurements taken from museum specimens suggest that snakes from the central Mediterranean area (Sardinia, Pantelleria, and Tunisia) are distinguished from those of the western Mediterranean area (Portugal and Morocco) by having significantly higher numbers of ventrals. A few natural-history notes on Sardinian specimens are presented, and a rationale for an urgent conservation plan is given.

Abstract:

The discovery early in this century of the exceptional longevity of the Sardinian population has given new impetus to demographic studies of this phenomenon during the classical period. In the 1970s, it was hypothesised that the average mortality rate in Roman Sardinia was lower than in metropolitan Rome itself, postulating an ancient precedent for the remarkable longevity observable nowadays in the island’s population. In the present study, the available evidence was examined in order to test this hypothesis. Literary, juridical, epigraphic, papyrological, anthropological and archaeological sources regarding the population of the Roman Empire, including Sardinia, were retrieved by accessing Science Direct, PubMed, Scopus and Google Scholar databases, as well as regional libraries, regardless of time limitation, and were independently reviewed by the authors. For Roman Sardinia, only funerary epitaphs were retrieved, in contrast with the numerous sources available for the whole Roman Empire. Inscriptions revealing the existence of three alleged nonagenarians, two centenarians, two ultracentenarians and one supercentenarian were found, corresponding to 2% in a total of 381 inscriptions. The majority were located in a highly Romanised rural area of central-western Sardinia. However, the ages reported in the epitaphs may be inaccurate because of the influence of confounders such as age rounding, approximations and/or amplifications, and are unrelated to the total number of inhabitants. In conclusion, the funerary evidence, the only available data from Roman Sardinia, is too weak to estimate the life expectancy of the local ancient population and cannot offer valuable arguments to support the hypothesis that exceptional longevity has been a Sardinian trait since Roman times.

Abstract:

SummaryThis study evaluated the prevalence of overweight and obesity in the male Sardinian population (Italy), and verifies that it has increased over the last 30 years. Data were collected during 2003–2004 from military registers in the Archive of the Military District of Cagliari for the years 1969 and 1998. A total of 22,345 forms were analysed from all Sardinia. The conscripts were classified on the basis of their place of residence and socioeconomic status. The overall prevalence of overweight and obesity in Sardinia were 4.33% and 0.55%, respectively, for the conscripts of 1969 and 9.8% and 3% for 1998. Olbia-Tempio (northern Sardinia) was the province with the highest incidence of overweight and obesity in 1969, and Nuoro (central Sardinia) had the highest incidence in 1998. Distribution of body mass index, overweight and obesity across the island showed a statistically significant heterogeneity that strongly decreased from 1969 to 1998. Among the conscripts of 1969, the incidence of overweight and obesity were higher in rural than in urban regions. An opposite trend was observed for the 1998 prevalence, it being more frequent in urban than rural regions. Comparison with other Italian regions was made. The percentages of overweight and obese individuals in Sardinia have markedly increased during the last 30 years, but their low incidence with respect to other Italian populations could be explained by the genetic peculiarity of the island. The change in the internal distribution of obesity clearly reflects socioeconomic changes.

Abstract:

e14094 Background: Role of KRAS, BRAF and PIK3CA mutations in pathogenesis of colorectal cancer (CRC) has been mostly clarified. In this population-based study, we investigated the incidence rates and roles for such somatic mutations in genetically isolated population of Sardinia. Methods: From April 2009 to July 2011, formalin-fixed paraffin-embedded tissues (n=478) were prospectively collected from Sardinian CRC patients at clinics across the entire island. Genomic DNA was isolated from tissue sections and screened for mutations in KRAS, BRAF, and PIK3CA genes by automated DNA sequencing. Results: Overall, KRAS tumor mutation rate was 30% (145/478 positive cases). Distribution of mutation carriers was however different within the island: 87/204 (43%) in North Sardinia vs. 58/274 (21%) in Middle-South Sardinia (p=0.023). Among 384 CRC cases whose DNA was available, only one (0.3%) mutation in BRAF gene was observed; conversely, PIK3CA was found mutated in 158/384 (41%) patients. An inverse distribution of PIK3CA mutation rates was observed within Sardinian population: 60/181 (33%) cases from northern vs. 98/203 (48%) cases from central-southern island. This heterogeneity in frequencies of KRAS/PIK3CA somatic mutations is consistent with already-reported discrepancies in distribution of germline mutations for other malignancies within Sardinian population. Preliminary clinical evaluation of 118 KRAS wild-type patients undergoing anti-EGFR-based treatment indicated lack of role for PIK3CA in predicting response to therapy in our series. Conclusions: Our findings further support the hypothesis that patients’ origin and genetic background may contribute to even determine the incidence rate of somatic mutations in candidate cancer genes.

Abstract:

The study of over 10,000 specimens of Dasytidae from about 35 collections has led to the conclusion that 8 genera and 32 species and subspecies of this family, all actually observed by the author, occur in Sardinia. This number is believed to be rather close to completion. A further 30 species, reported in the past as occurring on the island, are discussed and have been removed from the list. Identification keys based on external characters only are proposed for genera and species. However, for difficult groups and where confusion may arise, drawings of aedeagi are supplied. An annoted cataloguefollows with, for each species, synonymies, bibliography, a list of sampling localities with last year of collection, notes, and chorotype. A zoogeographical analysis shows that the Sardinian Dasytidae conform to a Central Mediterranean type, with rather strong North African influences and with a high presence of strict endemics (11 species), higher than in Corsica (7 species). Danacea (Allodanacaea) is no doubt the most interesting group with 7 taxa, none of which are spread all over Sardinia and 2 of which—D. (A.) gorditana Liberti and D. (A.) nympha Liberti—only occur in a tiny area in the Nurra region. Two species, Dasytes doderoi Pic and Aplocnemus (Diplambe) januaventi Liberti, both strict Sardinian endemics, are very rare and poorly known: the first is only known on two female specimens, both collected in the Gennargentu area many years ago; the second seems in a “safer” situation because several specimens have been collected recently. Trap samples (mainly Malaise) from the Marganai and Montimannu region-owned forests (SW Sardinia, respectively Carbonia-Iglesias and Medio Campidano provinces), are also discussed.

Abstract:

AbstractThe Central-Southern Apennines are the result of the collision between Europe and Africa. Despite the volume of existing literature, many problems remain unsolved such as the presence of Tertiary conglomerates containing exotic basement clasts. The lack of basement rocks in the Central-Southern Apennines implies that the origin of these clasts has to be sought in areas where the basement is extensively exposed. These include the Calabro–Peloritani arc and the Sardinia–Corsica block, which in Cenozoic time were connected to the Central-Southern Apennines. In this work we present the results of sedimentary, geochemical and petrographic analyses performed on the exotic basement-derived clasts. These analyses include lithological, major- and minor-element and rare Earth element compositions which are compared to analogous rocks from Calabria and Sardinia basements. Results indicate Eastern Sardinia as the primary source area for the studied conglomeratic units, linking the Central-Southern Apennines sedimentary cover to the Mesozoic carbonates of Eastern Sardinia prior to the opening of Tyrrhenian Sea. The Cilento unit (Campania) was directly fed by an uplifting Cenozoic orogen, and the Filettino, Gavignano (Latium) and Ariano Irpino (Campania) units were produced by the successive reworking of ‘Cilento-like’ sedimentary units. These results may imply that part of the Central-Southern Apennines represented a portion of the European margin of the Tethys.

Abstract:

Abstract: Mountain regions have been modified by human activity for centuries, which lead to more or less of significant changes in their ecosystems and consequently in landscapes. Some of these changes have been generated by traditional farming practices, such as the viticulture, giving distinctive shapes and identities of the space. Even if in many areas, the farming traditions have been abandoned as the consequences of technological progress applied in agriculture, Sardinia is a good example of vineyards cultural heritage preservation. Thus, linking this cultural heritage to the wine tourism, and promoting good practices at local initiatives, Sardinia limited the depopulation of the mountain areas. A very successful example of the increasing of positive tourism impact on territory planning, over the past few years, is the municipality of Mamoiada, in central Sardinia. The paper highlights the role of the using of environmental, cultural and identity tourist resources of Sardinian territory as far as they are part of good practices and furthermore, they could be the basis of sustainable development strategy. Moreover, the aim of our work is to investigate how the cultural, identity, landscape and socio-economic impact on the wine sector plays an important role for the rural community of Mamoiada.

Abstract:

AbstractThe scarce evidence of paleontological records between the upper Permian and the Anisian (Middle Triassic) of Western Europe could reflect (1) large stratigraphic gaps in the continental successions and/or (2) the persistence of disturbed conditions after the Permian–Triassic Boundary extinction event and the succession of ecological crises that occurred during the Early Triassic. In this context, the study of palynological associations, integrated with the stratigraphical and sedimentological data, plays a key role in dating and correlating the successions of the Western European domain and improves our understanding of environmental and paleoclimatic conditions. In some cases, pre-Anisian paleontological evidence is lacking, as in Sardinia (Italy), where a long gap encompasses the middle Permian (pars) to late Lower Triassic successions. Although fragmented and disseminated, the continental Lower-Middle Triassic sedimentary successions (Buntsandstein) of Sardinia have proved crucial to our understanding of the evolution of the southern edge of the Paleo-Europe and the different timings of the Tethys transgression (Muschelkalk facies) in some of these areas. Various paleogeographic reconstructions were attempted in previous works, without providing any consensus on the precise position of Sardinia and its surrounding seaways in the Western Tethys domain during this time interval. At present, the configuration and distribution of the subsiding and emerging landmasses and the temporal development of the transgressions of the Western Tethys during the Middle Triassic remain unclear. This work focuses on the stratigraphical, sedimentological and palynological aspects of three Middle Triassic continental-marine sedimentary successions in Sardinia, with particular attention to the analysis of the palynological associations sampled there, and it also provides a detailed review of all previous palynological publications on the Sardinian Anisian. The studied successions are: Su Passu Malu section (Campumari, SW Sardinia), Arcu is Fronestas section and Escalaplano section (Escalaplano, Central Sardinia). These sections were also correlated to other significant sections in the SW (Scivu Is Arenas) and NW (Nurra) parts of the island.

Abstract:

Intraspecific variation of passerine song may influence mate choice and consequently provides a potential mechanism for premating reproductive isolation in birds. Notable geographic variation of songs is particularly common in widespread bird species, such as the coal tit Periparus ater (Aves, Passeriformes, Paridae) having a large trans-Palearctic distribution range including allopatric populations. In this study, measurement and analysis of 16 song parameters from different Western Palearctic populations showed a relatively uniform song in all continental European and the island populations of Corsica and Sardinia. Song variation among and within these populations seems so variable that there is a broad geographical overlap of acoustic parameters between populations. However, songs from northwest African and Cypriot populations had lowest minimum frequencies and were thus significantly different from continental European, Corsican and Sardinian populations. To test for intraspecific species recognition and potential acoustic isolation of different Palearctic populations, we carried out field playback experiments on Central European coal tit males with songs from populations of the Eurasian (Germany, Latvia, Russian Far East, Japan) and the Mediterranean region (northwest Africa, Cyprus, Corsica, Sardinia). Eurasian song types elicited similar strong territorial reactions in Central European coal tits as local control songs. In contrast, none of the Mediterranean songs evoked any notable reaction. Thus, there is geographic variation in coal tit song across continents that coincides with reduced species recognition between Central European and Mediterranean populations.

Abstract:

Apesorgia nera is an ancient Sardinian grape variety present not only in the old vineyards, but also in courtyards and gardens, throughout the island, mainly in Southern and central Sardinia. This work aims to contribute to the ampelographic, chemical and genetic characterization of this autochthonous variety. The comparison of microsatellite profiles obtained with the main “on line” databases did not allow to identify other vines with the same profile. Apesorgia nera is a variety currently being registered in the National Register of Vine Varieties. The long tradition of cultivation, the presence in historical documents, the qualitative and productive characteristics make it an interesting variety, mainly for the local market.

Abstract:

Data-Deficient (DD) species are currently under threat because of the paucity of information regarding their abundance, distribution and biological traits. In this study we analysed temporal trends and bioecological features of the DD shark, Squalus blainville. Biological and fishery data were collected through two different scientific surveys spanning 1994–2018 and commercial hauls around Sardinia Island (central western Mediterranean) from 2008 to 2018. The analysis of temporal trends based on abundance data revealed a significant population decline over time. The late attainment of maturity and low fecundity of S. blainville are suspected to have contributed to making it highly vulnerable to overfishing. No bathymetric segregation by sex and size was found. However, the almost exclusive presence of pregnant females south-west of Sardinia could be due to sexual spatial segregation. This is also supported by histological findings showing long-term sperm storage to ensure the persistence of the species when females and males are separated. The documented decline of this species, its low reproductive potential and similarities in the depth distribution of immature and mature individuals indicate the need for urgent protection plans for S. blainville in Sardinian waters.

The analysis was mainly focused on the specific distinction and formal description of a new species, H. rosannae sp. nov., from the Sulcis-Iglesiente region (SW Sardinia), morphologically distinctly separated from both the nearly parapatric H. tyrrhena Binaghi, 1961 (central and northern Sardinia) and the allopatric H. evanescens Rey, 1884 (Corsica). Two hypothetical palaeogeographical scenarios explaining the specific differentiation of the three species are briefly discussed.

Abstract:

Sardinia was affected by an intense igneous activity which generated calc-alkaline products during the Oligo-Miocene period. The volcanic substance shows large variations, ranging from pyroclastic flow deposits, lava flows and domes. By composition, the deposits are all primarily dacites and rhyolites, with subordinate andesites and very scarce basalts. The rhyolite lavas show porphyritic and ash-flow tuffs. Ignimbrite structures are found in the dacitic domes and rhyolitic lavas. These rocks—commercially known as “Trachytes of Sardinia”—used to be quarried in all historical provinces, mainly in the central part of the island to be used as ornamental and building stone. They continue to be commonly used nowadays, but their use dates back to the prehistoric age. They are easily found in many nuraghi, “domus de janas”, holy wells, Roman works (mosaics, paving, roads, bridges), many churches built in Sardinia and practically in all kinds of structural elements in public and private buildings, such as walls, houses, and bridges. Contrary to the granitoid rocks, whose appearance is largely influenced by the mineralogical composition, the aesthetic feature of volcanic rocks is rather affected by the widest range of colors, structure and texture, i.e., shape, size and distribution of mineral components, porphyric index, etc. “Trachyte” is quarried opencast with the “single low step” method, with descending development, with prevalent use of double-disc sawing machines. Whenever the stone deposit allows higher steps, the chain cutting machine, in combination with diamond wire, becomes the preferred extraction solution. This study aims to at look Sardinian “trachytes” from a geoheritage perspective. After a geological-petrographic framework, the paper discusses the historical uses of “trachyte” in Sardinia. The current state of the art of “trachyte” quarrying, processing and usage in the Island is also described. An analysis of the “trachyte” production has been carried out. Finally, a consideration about how to enhance geotourism in the area is suggested.

Abstract:

In the fresh waters of Sardinia (Italy), the non-indigenous crayfish species Procambarus clarkii has been reported from 2005, but, starting from 2019, there have been several reports of a new non-indigenous crayfish in southern and central areas of this Mediterranean island, and its morphology suggests that this species may be the marbled crayfish Procambarus virginalis. Forty-seven individuals of this putative species were analyzed, using the mitochondrial gene Cytochrome c Oxidase subunit I as molecular marker to identify this crayfish and investigate the level of genetic variability within the recently established population. Phylogenetic and phylogeographic analyses were carried out on a dataset including sequences from the Sardinian individuals and from all congenerics available in GenBank. Results showed that the new Sardinian crayfish belong to the species P. virginalis. All the sequences belonging to P. virginalis from European countries are identical, with only few exceptions found among Sardinian individuals. In conclusion, this paper highlights the occurrence of a new further alien species in the Sardinian fresh waters, which are already characterized by the high presence of non-indigenous species.

Abstract:

One of the most important megalithic groups in Western Europe in terms of number and characteristics is the group of over 200 monuments of various types in Sardinia. It now seems to be confirmed that the rise of the megalithic phenomenon was during the culture of San Michele of Ozieri (Late Neolithic, 4000-3300 B.C.E.). The Sardinian dolmen graves, however, had a maximum distribution during the Chalcolithic, as evidenced by most of the finds from excavations. The phenomenon also shows a close relationship beyond Sardinia and especially with the monuments of Catalonia, Pyrenees, non-coastal departments of French-midi, Corsica and Puglia.About 90 dolmen graves of various types have been investigated, namely the simple type, “corridor” type, “allée couverte” type, and others of uncertain attribution, located in central-western Sardinia, and particularly in a significant area of ca. 3500 km2 coinciding with the historical regions of Marghine-Planargia, Middle Valley of Tirso and Montiferru. This includes some 40% of all Sardinian dolmens. Locational trends and relationships with regard to landscape elements were studied with the aid of GIS methodologies such as viewshed and cost surface analysis. This allowed an evaluation of the role of visual dominance on the surroundings in relation to waterways and natural access routes.These dolmens enjoy an isolated positional character, being found more often in high plateaus, but also on low plateaus and hills. Although different concentrations are found in dolmenic graves, these do not seem to have any direct relationship among them, but their influence is apparently directed towards travel routes and sensitive elements of the landscape that have capabilities of territorial demarcation.The particular location emphasizes the significance of these monuments as territorial markers for segmentary societies. It seems that a dolmen was constructed according to the territory immediately surrounding it. This reinforces the hypothesis of there being a secondary task, in addition to that of burial, to symbolize a message or landmark for those who moved towards "another" territory: a sign of belonging.

Abstract:

The sediment accumulation rate in the Sardinia and Sicily channels in the central part of the Mediterranean Sea was studied by using short-lived radionuclides (210Pb and 137Cs) in two deep sediment cores. Different sedimentation regimes were identified indicating substantial differences in accumulation rates and historical patterns. The 210Pb-derived mean accumulation rate found in the Strait of Sardinia was 0.05 g.cm-2.y-1, lower than that in Sicily Channel (0.1 g.cm-2.y-1) suggesting an inverse correlation with water depth. Excess 210Pb inventories were 24 ± 1 and 6.0 ± 0.4 kBq.m-2, while the fluxes to the sediment were 745 ± 31 and 188 ± 11 Bq.m-2.y-1 in Sicily and Sardinia channels, respectively. 137Cs failed to use for the validation of the established chronologies, while its inventories found 450 Bq.m-2 and 355 Bq.m-2 in the Sicily and Sardinia channel, respectively.

Abstract:

Abstract The Sardinia Channel is located in a 400 km-long submerged section of the Apennine-Maghrebian branch of the Alpine chain. The Sardinia Channel connects the Algerian-Ligurian-Provençal to the Tyrrhenian oceanic basins. The structure of this region results from the superposition of two tectonic regimes: an earlier crustal thickening and a later crustal thinning. The crustal thickening is the consequence of the shortening which occurred in the late Oligocene–early Miocene during the build up of the Apennine-Maghrebian Orogen. This thickening is coeval with the rotation of the Corsican-Sardinian block and the opening of the Provençal-Algerian back-arc basin. All of these structures, as well as the magmatic arcs in Sardinia and Tunisia, i.e. the Galite Archipelago, are connected to the subduction of the Tethyan Ocean. The crustal thinning is associated with the rifting of the Tyrrhenian Basin, which occurred just before the Messinian salinity crisis and was accompanied by significant erosion throughout the region. This erosion was followed by a period of thermal subsidence linked to the opening of the Tyrrhenian oceanic basin in the Plio-Quaternary, interspersed with minor episodes of compression. On the Sardinian margin, the dives led to the discovery of a submarine volcano, dated at 12.6 Ma, and composed of shoshonitic andesites with lamprophyre inclusions, and to the characterization of the nature and structure of the underlying basement, consisting of tilted blocks of Hercynian metamorphic and granitic rocks and their sedimentary cover. The sea floor morphology reflects this structure. The other areas of the Sardinia Channel explored, i.e. its southern margin and central ridge, belong to the Calabrian-Peloritanian-Kabylian group (CPK). They are composed of a metamorphic and granitic Hercynian basement deformed during the Alpine orogeny, which is stratigraphically overlain by an Oligo-Miocene detrital cover of Peloritanian or Kabylian type, and tectonically overlain by the so-called “flysch nappe”. Throughout the CPK domain these formations were subjected during the Oligo-Miocene, at ca. 23 Ma ago, to a first denudation event, and during the Tortonian, ca. 10-8 Ma ago, to a second denudation, which has been connected to the opening of the Tyrrhenian basin. Structures, microstructures and thermochronological data indicate relatively low P-T conditions for the extensional deformations: this suggests that these units remained at shallow depths in the Apennine-Maghrebian Orogen, and were relatively preserved from the Messinian erosion. The age (12.5 Ma) and nature of the volcanic sequence in the Sorelles is closely comparable with the calc-alkaline suite of the Galite Archipelago, Tunisia. Thus, the data gathered during the dives in the Sardinia Channel give new constraints to the reconstruction of the kinematic evolution not only of the region, but also to the entire western Mediterranean.

Abstract:

A sample of 146 Sarda bucks from eight subregions of Sardinia, Italy (Nuorese, Barbagia, Baronia, Ogliastra, Sarrabus, Guspinese, Iglesiente, Sulcis) were characterized for Y-chromosome and mtDNA markers to assess the levels of population substructure. Five polymorphic loci (SRY, AMELY, ZFY, and DDX3Y) on the Y-chromosome were genotyped. The control region of mtDNA was sequenced as a source of complementary information. Analysis of Y-chromosome data revealed the segregation of 5 haplotypes: Y1A (66.43%), Y2 (28.57%), Y1C (3.57%), Y1B1 (0.71%), and Y1B2 (0.71%). High levels of Y-chromosome diversity were observed in populations from Southwest Sardinia. The FST values based on Y-chromosome and mtDNA data were low, although a paternal genetic differentiation was observed when comparing the Nuorese and Barbagia populations (Central Sardinia) with the Sulcis, Iglesiente, and Sarrabus populations (Southern Sardinia). AMOVA analysis supported the lack of population substructure. These results suggest the occurrence of a historical and extensive gene flow between Sarda goat populations from different locations of Sardinia, despite the fact that this island is covered by several large mountain ranges. Introgression with foreign caprine breeds in order to improve milk production might have also contributed to avoiding the genetic differentiation amongst Sarda populations.

Abstract:

AbstractRecent studies on albitite rocks located in the granodiorite complex of Central Sardinia have revealed that epidote has a widespread occurrence as a light rare-earth element (LREE)-bearing accessory common phase. Titanite has been recorded as a heavy rare earth element (HREE)-bearing mineral. The Hercynian granodiorite complex of Central Sardinia is composed chiefly of quartz, Ca-plagioclase, K-feldspar and biotite and of a wide variety of secondary assemblages, mainly allanite, titanite and zircon. Albitic plagioclase and quartz are the main mineral components of the albitites. Additional minerals include, besides allanite and epidote, a more calcic-plagioclase (oligoclase), K-feldspar, chlorite, titanite and more rarely muscovite. The mineral assemblages and REE-bearing minerals of albitites were analysed by wavelength dispersive spectrometry (WDS). Chemical data suggest that there is a near complete solid-solution between epidote and allanite whereas little variations in HREE of titanites were detected. In epidote-group minerals a pronounced zoning in REE was observed while titanite was recorded unzoned. Textural relations were studied by SEM to distinguish primary from secondary epidotes. Chemical criteria to recognize magmatic from alteration epidotes were also applied. The alteration epidotes mainly occur and generally originate from plagioclase alteration and from leaching of magmatic allanite. Comparison of textures using both the SEM technique and EPMA data showed that the characteristic ‘patchy zoning’, observed in epidotes, corresponds with different amounts of REE in these minerals.The schematic model proposed for the epidote-forming reactions during the metasomatic processes that affected the granodiorites involves: (i) the instability of the anorthitic component of plagioclase; (ii) the simultaneous formation of albite; (iii) the leaching of the magmatic allanite with a redistribution of REE in the epidotes of the albitites.

Abstract:

In this study, we analyzed the effects of grazing on native and endemic plant diversity, as well as its relationship with pastoral value along a gradient of abiotic and biotic factors and types of land management in a mountainous area of central-eastern Sardinia, Italy. Plant diversity was estimated by conducting a floristic survey within plots. In total, 231 plant species were recorded in 63 plots distributed within the study area, and this total number included 20 endemic species. Species richness was mainly affected by the type of management, soil attributes, altitude, and bioclimate. Pastoral value was strongly affected by nutrient availability and bioclimate. Our results suggest that the cover of endemic species increases with altitude. Finally, in Sardinian rangelands, a negative effect of grazing pressure on endemic species was observed.

Abstract:

The genus Teucrium L. (Lamiaceae) is a genus growing in mild climate zones, particularly in the Mediterranean Basin and Central Asia. It is represented by 11 taxa in Sardinia (Italy), living commonly in sunny habitats. In this study, the following eight Sardinian Teucrium taxa were selected, and the essential oils (EOs), obtained by stem distillation, were analyzed by GC–FID and GC–MS: T. capitatum subsp. capitatum, T. chamaedrys subsp. chamaedrys, T. flavum subsp. glaucum, T. marum, T. massiliense, T. scordium subsp. scordioides, T. scorodonia, and T. subspinosum. The comprehensive analyses led to the identification of 87 constituents representing the majority of the volatile compounds. Significant differences, both qualitative and quantitative, were observed between the taxa. Overall, monoterpenes and sesquiterpenes characterized all Teucrium EOs: T. capitatum subsp. capitatum and T. flavum subsp. glaucum revealed the highest content of monoterpene hydrocarbons, while in the other Teucrium taxa sesquiterpene hydrocarbons prevailed. Worthy of note, diterpenes were found only in T. marum and T. subspinosum, whereas T. massiliense was rich in non-terpenic oxygenated compounds. To the best of our knowledge, this is the first comprehensive report on the chemical composition of EOs obtained from Sardinian Teucrium species.

Abstract:

Sardinian contemporary literature and films have recently recovered an extensive heritage of folk myths and legends taken from the oral tradition. Legendary figures, such as accabadoras (female figure who was enabled with the task of easing the sufferings of the dying people), and fantasy creatures, such as cogas, surbiles (‘vampire witches’), janas (‘fairies, pixies’), and panas (‘the ghosts of women who died in childbirth’) are being revived by writers and film directors with the purpose to bring their memory back to life and share it with a wide audience of readers and spectators. The analysis of imaginary and legendary creatures in Sardinian contemporary literature cannot overlook orality and its central role in shaping popular imagination over the centuries. Writing has replaced orality, whilst mass media and digital media are getting the upper hand over storytelling as a practice of community and family aggregation, meant to mark the long working hours and scare the children, amongst the most common functions of Sardinian oral storytelling. The literary corpus includes fairy tales, novels, tales and legends dealing with the Sardinian oral tradition, whilst on the cinematic side I will examine short films, feature films and documentaries made in Sardinia over the last fifteen years.

Abstract:

AbstractThe phylogeography of the colubrid snake Hierophis viridiflavus was estimated using ND4 mtDNA sequences and a fragment of the nuclear marker β-fibrinogen intron 7. This species has a wide distribution across the Mediterranean region, and is characterized by three distinct colour patterns (“viridiflavus”, abundistic, and melanic-melanotic) with a quite well defined geographic distribution. The “viridiflavus” pattern occurs in the northwestern and central areas of the species' range, the abundistic pattern is typical of the individuals from Corsica and Sardinia, and the melanic-melanotic coloration is present in northeastern and southern Italy, and Sicily. A total of 42 individuals from most of the species' range (including Pyrenees, central France, Italian Peninsula, Corsica, Sardinia and Sicily) were analyzed. Results support the existence of two different mtDNA lineages, one from Spain, France, Corsica, Sardinia, and continental Italy mainly west of the Apennines, and another one occurring in the southern part of Italy and northeast of the Apennines, with a 4% genetic divergence between them. Since both mtDNA lineages are found in northwestern Italy, where the “viridiflavus” colour pattern is almost exclusively found, it is clear that colour pattern is not linked to the mtDNA clades. The same is evident for β-fibrinogen, which is not subdivided geographically in the way that the mtDNA lineages are. Regarding Corsica and Sardinia, the limited genetic differentiation of island populations from the western continental lineage, indicates that these populations are a result of a recent colonization in accordance with recent described phylogeographic patterns.

Abstract:

Abstract. In Sardinia (Italy), the highest frequency of extreme events is recorded in the Central-East area (3–4 events per year). The presence of high and steep mountains near the sea on the central and south-eastern coast, causes an East-West precipitation gradient in autumn especially, due to hot and moist currents coming from Africa. Soil structure and utilization make this area highly vulnerable to flash flooding and landslides. The specific purpose of this work is to provide a description of the heavy rainfall phenomenon on a statistical basis. The analysis mainly focuses on i) the existence of trends in heavy rainfall and ii) the characterization of the distribution of extreme events. First, to study possible trends in extreme events a few indices have been analyzed by the linear regression test. The analysis has been carried out at annual and seasonal scales. Then, extreme values analysis has been carried out by fitting a Generalized Pareto Distribution (GPD) to the data. As far as trends are concerned, different results are obtained at the two temporal scales: significant trends are obtained at the seasonal scale which are masked at the annual scale. By combining trend analysis and GPD analysis, the vulnerability of the study area to the occurrence of heavy rainfall has been characterized. Therefore, this work might support the improvement of land use planning and the application of suitable prevention systems. Future work will consider the extension of the analysis to all Sardinia and the application of statistical methods taking into account the spatial correlation of extreme events.

Abstract. In 2014, the Sardinian Regional Department of Hygiene, Health and Social Security promoted the Regional Prevention Plan, which embraced the protection of the population from exposure to indoor pollutants, including radon gas. The programme foresaw: the drafting of “Guidance for the construction/renovation of buildings”; radon monitoring and mapping activities during a dedicated campaign based on geological surveying; a radon health impact assessment; community involvement and a radon risks communication campaign. The objectives of the programme were focused to protect Sardinian population from radon risk, with special reference to vulnerable and susceptible subjects, spread knowledge about risks and the opportunities to reduce them. Using a Health Impact Assessment procedure, the number of attributable deaths was estimated based on radon exposure levels, also visible as preventable events by implementing preventive actions. The purpose of this article is to illustrate the activities carried out, with specific reference to the use of communication to develop each action, to understand strengths and weaknesses and the lessons to be applied in Sardinia and other areas. Monitoring and evaluation results indicate that the health of populations living in radon-exposed areas can be significantly improved by reducing exposure to radon and synergistic risk factors. It is essential to strengthen awareness-raising events using historical and acquired knowledge, and to monitor progress in order to reinforce further actions, as these schemes should be planned for the long term, with central coordination and continuous evaluation. The case of radon risk management and communication in Sardinia offers a number of suggestions and lessons learned, both for the continuation of the work that is expected to be very intense in the coming years, and for the problems that may arise in other regions and countries affected by radon risk.

Abstract:

The ocellated skink (Chalcides ocellatus) is a widespread lizard, naturally distributed between the Maghreb and coastal Pakistan, with few insular populations in the Mediterranean coastal area. Some populations of this species have also been recorded in peninsular Italy, Campania and Southern Tuscany due to accidental introductions via touristic and commercial routes. In this work, we conducted genetic analyses on mitochondrial DNA COXI, cytb and 16S mtDNA genes on a sample of Italian insular and peninsular populations. Differently from what previously suggested, the nucleus in Portici (Southern Italy) may have originated from Sardinia. The intense trade and touristic traffic between Sardinia and Southern Tuscany may have been responsible for the introduction of this lizard also to Central Italy.

Abstract:

Several metallogenic periods took place at different moments of the geological evolution of Sardinia, but at places they interacted: the close correlation between the metal parageneses in the Ordovician – Silurian sequences, outcropping in the central part of the island, and the veins and masses associated with the Hercynian magmatism is depicted. The volcanic-sedimentary mixed-sulphide lenses contained in Silurian occurrences show clear sedimentary structures, and the connection with coeval volcanics seems evident. These mineralizations are thought to be the protores for the subsequent metallogenic cycle related with the Hercynian orogenesis which had a strong effect as a promoter of the remoulding of preexisting mineral concentrations to give new ore- and industrial minerals deposits. Several geochemical campaigns have covered the entire island, and wide areas of the Paleozoic basement, mostly localised in the internal zones, showed high base- and heavymetals contents. A new prospecting programme has been started in Central Sardinia; it follows the ore-bearing horizon along the Ordovician-Silurian boundary with the purpose to better understand these primary metal depositions, their relationships with geodynamic structures, and ore mobilisation caused by the Hercynian granites. The geochemical anomalies along this horizon detected in the area of “Castello Medusa” support detailed prospecting works.

Abstract:

The Corsican red deer is an endangered subspecies that needs artificial translocation projects to gain its complete recovery with the formation of viable, interconnected populations. Between 2007 and 2017, we performed two reintroduction projects in four sites in central–eastern Sardinia via tracking 32 deer by means of GPS/GSM radiotelemetry. On the basis of the obtained results, we built a species distribution model (SDM) using MaxEnt software, selecting 200 random points from the merged deer core areas as presence data. Furthermore, to evaluate the sanitary risk linked to artificial translocations, we analyzed deer positivity to Bluetongue virus (BTV) in the founder populations. The SDM showed a high deer capability to colonize central–eastern Sardinia, but it also showed the possibility of spreading BTV to domestic sheep because sanitary analyses confirmed the virus’ presence in the founder populations. Our main conclusion was that reintroductions are effective tools for the long-term conservation of the Corsican red deer, as long as sanitary risks are minimized by means of sanitary monitoring of translocated deer.

Abstract:

Bemisia tabaci is a key pest of horticultural, fibre and ornamental crops worldwide, primarily as a vector of plant viruses. In Italy, B. tabaci has established since the 1980s–1990s in southern regions as well as in Sicily and Sardinia. Recent reports of infestations in some areas of central Italy prompted a new survey to assess the whitefly distribution in the country as well as to update the species and haplotype composition of the populations present in southern Italy and in the main islands. The survey confirmed that B. tabaci is nowadays established in central Italy even at more northern latitudes than those noticed before. Most of the specimens collected throughout the country belonged to the Mediterranean (MED) species. The MEDQ1 and Q2 haplogroups were prevailing in open-field and greenhouse cultivations, respectively, except in Sardinia where only Q1 specimens were found on a wide range of crops and weeds. Population genetics analyses showed that several MEDQ1 haplotypes currently occur in Italy and their distribution is unrelated to evident temporal and geographic trends, except for a new genetic variant which seems to have originated in Sardinia. The MED species is known to better adapt to insecticide treatments and high temperatures, and its northward spread in Italy may have been favoured by the intensive agricultural practices and steady increase in both winter and summer temperatures occurring in the last few decades. The extensive presence of B. tabaci in Italy proves that a strict surveillance for possible new outbreaks of whitefly-transmitted viruses should be addressed to a range of sites that are expanding northwards.

Abstract:

AbstractAspicilia crespiana Rico is described as a new species from central Spain and Sardinia (Italy). In central Spain it is common and has a well-defined ecology. It is found at middle to high altitudes (from 400 to 1900 m), overgrowing mosses on exposed and horizontal to more or less vertical siliceous rocks. Closely related to the A. contorta (Hoffm.) Kremp. complex, A. crespiana differs in its muscicolous habit and thallus development, consisting of a network of lichenized squamules interlinked by fungal rhizomorphs.
