  • Villa Della Nurra Region: Sardinia Sleeps: 4
    Villa Della Nurra Region: Sardinia Sleeps: 4 Overview Villa Della Nurra is a sleek, contemporary designed bungalow on the open northwestern Nurra plains of Sardinia, set within acres of lush olive groves farm. Positioned in a tranquil, rural corner between Porto Torres and Alghero, the villa marries slick style with traditional Sardinian charm. Both simple but effective, Villa Della Nurra offers newly built, low-key and unpretentious holiday living: gorgeous neutral and minimal interiors will suit those aesthetes who go for a modern look. Stream-lined, open plan living at its best. The lateral layout and wonderful soft interior light ensure this is not just another quaint little holiday cottage. Design finesse is apparent, from exposed wooden beams, state-of-the-art kitchen, trendy spotlighting - subtle luxury sets the tone. Decked out in stunning soft greys, whites and charcoals, the living space is both cosy and contemporary - Villa Della Nurra provides both function and style without going overboard. Sleek counter-tops, ample kitchen space integrated with an informal open plan dining area - this space offers the most natural setting for a family or friends who enjoy understated living. The large living space flows naturally onto the large, shaded terrace. Wooden shutters and exposed timber offer a little nod to local style. The vibrant red sofa and flat screen TV are in keeping with the casual, upbeat feel of the villa. Air-conditioned throughout, WiFi is provided along with all the little luxuries guests would expect. The two bedrooms are spacious and crisp; again, unfussy in keeping with the very sleek and natural feel of the villa, yet finished to a high level of quality.

  • Pier Virgilio Arrigoni the Discovery of the Sardinian Flora
    Pier Virgilio Arrigoni The discovery of the Sardinian Flora (XVIII-XIX Centuries) Abstract Arrigoni, P. V.: The discovery of the Sardinian Flora (XVIII-XIX Centuries). — Bocconea 19: 7-31. 2006. — ISSN 1120-4060. The history of the floristic exploration of Sardinia mainly centres round the works of G.G. Moris, who in the first half of the XIX century described most of the floristic patrimony of the island. But it is important to know the steps he took in his census, the areas he explored, his publications, motivations and conditions under which he wrote the "Stirpium sardoarum elenchus" and the three volumes of "Flora sardoa", a work moreover which he left incomplete. Merit is due to Moris for bringing the attention of many collectors, florists and taxonomists to the Flora of the Island, individuals who in his foot-steps helped to complete and update the floristic inventory of the island. Research into the history of our knowledge of the Sardinian Flora relies heavily on the analysis of botanical publications, but many other sources (non- botanical texts, chronicles of the period, correspondence) also furnish important information. Finally, the names, dates and collection localities indicated on the specimens preserved in the most important herbaria were fundamental in reconstructing the itineraries of the sites Moris visited. All these sources allowed us to clarify several aspects of the expeditions, floristic col- lections and results of his studies. The "discovery phase" of Sardinian Flora can be considered over by the end of the XIX century with the publication of the "Compendium" by Barbey (1884-1885) and "Flora d'Italia" by Fiori & Paoletti (1896-1908).

Carlson Steven Oberhelman Head of Department, Donny L. Hamilton December 2009 Major Subject: Anthropology iii ABSTRACT Foreign Influences and Consequences on the Nuragic Culture of Sardinia. (December 2009) Margaret Choltco, B.A., The Pennsylvania State University Chair of Advisory Committee: Dr. Shelley Wachsmann Although it is accepted that Phoenician colonization occurred on Sardinia by the 9th century B.C., it is possible that contact between Sardinia‟s indigenous population and the Levantine region occurred in the Late Bronze Age (LBA). Eastern LBA goods found on the island are copper oxhide ingots and Aegean pottery. Previously, it has been suggested that Mycenaeans were responsible for bringing the eastern goods to Sardinia, but the presence of Aegean pottery shards does not confirm the presence of Mycenaean tradesmen. Also, scholars of LBA trade have explained the paucity of evidence for a Mycenaean merchant fleet. Interpretations of two LBA shipwrecks, Cape Gelidonya and Uluburun, indicate that eastern Mediterranean merchants of Cypriot or Syro-Canaanite origin, transported large quantities of oxhide ingots from the Levant towards the west.

In northern Sardinia, which corresponds to the Inner zone of the chain, the metamorphic grade rapidly increases towards the NE from biotite to sillimanite+K-feldspar zone. The highest grade rocks cropping out in the Migmatite zone reached amphibolite facies conditions in the sedimentary and igneous-derived migmatite and eclogite/granulite facies in the enclosed metabasite lenses. Evidence of HP metamorphism has also recently been found more to the south in micaschist from the garnet zone. The D1 deformation can be observed in the southern part of the Inner zone, whereas, moving progressively northwards, the D2 deformation progressively obliterates the previous foliation.

  • A Huge Caseid Pelycosaur from North−Western Sardinia and Its Bearing on European Permian Stratigraphy and Palaeobiogeography
    A huge caseid pelycosaur from north−western Sardinia and its bearing on European Permian stratigraphy and palaeobiogeography AUSONIO RONCHI, EVA SACCHI, MARCO ROMANO, and UMBERTO NICOSIA Ronchi, A., Sacchi, E., Romano, M., and Nicosia, U. 2011. A huge caseid pelycosaur from north−western Sardinia and its bearing on European Permian stratigraphy and palaeobiogeography. Acta Palaeontologica Polonica 56 (4): 723–738. Skeletal remains, some loose on the surface and others still embedded, have been recovered from the uppermost part of an outcrop of the Permian Cala del Vino Formation located near Torre del Porticciolo (Alghero, Nurra, NW Sardinia). Taphonomic analysis suggests that all the elements pertain to a single individual; ongoing studies indicate the fossil repre− sents a large caseid close (or referable) to Cotylorhynchus; otherwise restricted to a narrow geographic and stratigraphic zone of the central USA. The new finding, the first of a caseid in Italy and one of few in Europe, enlarges the known distri− bution of the family and provides a significant and key chronostratigraphic constraint for the continental succession of this area and, in turn, helps establish a stratigraphic framework for the Permian units cropping out in Italy and southern France.

This is particularly true in the Italian demographic experience, especially for some regions. OBJECTIVE We wish to improve the knowledge of the determinants of fertility transition in Sardinia, a region situated in the heart of the Mediterranean but paradoxically one which is the least „Mediterranean‟ region of the country.

    Journal of Environmental and Tourism Analyses Vol. 2. 1 (2014) 19-32 Relict Forms of a Disappeared Mountain. The Periglacial Deposits in Asinara Island-Sardinia, Italy Sergio GINESU1a, Donatella CARBONIb, Pierpaolo CONGIATUc a Department of Science for Nature and Environmental Resources – University of Sassari, Piazza D'Armi, 17, 07100, Sassari, Italy bDepartment of Humanistic and Social Sciences – University of Sassari, Piazza D'Armi, 17, 07100, Sassari, Italy c Asinara National Park, Via Iosto, 7 – 07046, Porto Torres (SS), Italy Abstract: Asinara Island is located in northwestern Sardinia (Italy) and only recently has been divested as a maximum-security prison and returned to nature protection as a National Park with Marine Protected Area along the coastal perimeter. Geologically, the island is formed by a Paleozoic basement in transition between the metamorphic rocks and the Pre-Hercynian granitic batholith of Sardinia. New surveys carried out to reconstruct the recent evolution of the landscape have shown a lot of deposits formed by large blocks of granitoid and anphibolitic rocks representing a favorable situation to produce this material formation in terms of differential erosion in periglaciar environment. Similar morphologies are possible to observe in many places in Sardinia continental hard rocks as effect of the conditions of refreezing periods ("glacial"). These deposits are commonly known as " block streams " or " block fields " and reported for the first time in Italy in 1990 in the central area of the island of Sardinia, about 500 meters above sea level. Their presence in Sardinia is always documented in a range of altitudes not less than 350-400 meters and, in this case for the first time they have been identified in close proximity to the coastline.
