Reccopolis was a new urban foundation of the late sixth century AD, built by King Liuvigild during the period of the Visigothic state formation. The city was equipped, alongside other facilities, with an aqueduct built ex novo in the Roman technique. This has only recently been studied. The construction of a new city and a new aqueduct indicates a great economic effort by the Visigothic ruler: the event was in itself also a grand act of propaganda in addition to its obvious functional purpose. The aqueduct is itself unmatched in public constructions of this period. 相似文献

This paper presents the results of a pilot study using dental microwear analysis on 23 sheep and goat teeth dated to the 6th century BC from the Iron Age site of El Turó Font de la Canya (Barcelona, Spain). This study aimed to reconstruct livestock management practices and landscape use. The dental microwear pattern indicates that sheep and goats could have been grazing in the same area where vegetation was composed of shrubs, bushes and non-graminaceous plants on an eroded landscape, although additional supplies of fodder cannot be excluded. This scenario is compatible with the archaeological and palaeoenvironmental data which suggest a possibly increased territoriality, land degradation and an increase of woodland clearance during Iron Age in the North-east of the Iberian Peninsula. Furthermore, we applied two recent microwear approaches which provide more information about mortality events and the possibility of distinguishing between an intensive and extensive management. This paper demonstrates how this method can be used to better understand animal husbandry practices and landscape use in Late Prehistory. 相似文献

UNESCO’s 207 natural heritage World Heritage Properties are at risk from climate change, but risk varies widely among properties. I offer a global model based on multi-model general circulation model (GCM) ensembles, vulnerability and Human Influence (HII), producing the World Heritage Vulnerability Index (WHVI), a measure of relative risk among properties. Nineteen properties are most at risk (i.e. WHVI > mean + 1 SD). Those include islands (i.e. Vallée de Mai, Aldabra, East Rennell, Teide, Laurisilva of Maderia, Isole Eloie, Pitons Management Area, Morne Trois Pitons and Galapagos Islands), coastal properties (i.e. Everglades, Desembarco del Granma, High Coast and Kvarken Archipelago, Doñana, Brazilian Atlantic Islands, Ichkeul and the Sunderbans) and mountainous properties (i.e. the Pyrenees Mont Pérdu, Nanda Devi and the Valley of Flowers, and Mount Kinabalu). Three properties (i.e. Teide, Isole Eloie and the Pitons Management Area) are geologic, apparently relatively resistant to short-term climactic changes. The remaining 16 are likely to respond to climactic changes in the next 40 years; those changes may threaten their World Heritage status. Those properties are where society could most effectively invest in adaptation. I identify adaptive strategies and next steps for proactive climate change adaptation in the 16 natural heritage properties on the World Heritage List most at risk. 相似文献
