Presence of the genus Cuon in upper Pleistocene and initial Holocene sites of the Iberian Peninsula: new remains identified in archaeological context…
2010
The dhole (Cuon alpinus) has been documented on the Iberian Peninsula throughout the Middle and Upper Pleistocene in archaeological and palaeontological contexts. However, this is an uncommon species among the Iberian quaternary faunae as a whole. This paper focuses on the remains of the genus Cuon recovered in three different sites of the Iberian Mediterranean region and their morphological and osteometrical study. By comparing these with fourteen complete skeletons of Canis lupus, as well as with other remains of C. alpinus, we intend to highlight some anatomical and metrical differences between Cuon and Canis that, added to those already published, could be a functional base-line for the…
From pedologic indications to archaeological reconstruction: deciphering land use in the Islamic period in the Baida district (north-western Sicily)
2013
Abstract The aim of this work was to detect imprints on soil properties from former Islamic land use (9th to 11th century) using a multi-method, soil-chemical approach. Four soil profiles (with buried horizons) found in the vicinities of former Islamic settlements in Sicily were analysed for phosphorus (total, organic and inorganic), nitrogen (total, NO 3 − and NH 4 + ), carbon compounds (δ 13 C, lipids, polycyclic aromatic hydrocarbons (PAH) and functional groups), physical and chemical C-fractions and the state of soil weathering. Two soil profiles contained ceramic sherds from the Islamic period. Inorganic nitrogen forms, phosphorous and the PAH content indicated strong impacts from trad…
The ivory workshop of Valencina de la Concepción (Seville, Spain) and the identification of ivory from Asian elephant on the Iberian Peninsula in the…
2013
During excavations in the huge ditched enclosure of Valencina de la Concepcion (Seville, Spain), the main centre from the first hierarchical framework-settlement in the Guadalquivir Valley, a pit with remains of a context for producing ivory artefacts, dating from the first half of the 3rd millennium BC, was discovered in the large metallurgical nucleate workshops. Scientific (Optical Microscopy, FIRT and Raman Spectroscopy, C/N Isotope Ratio Mass Spectrometry) analyses revealed that the ivory belonged to Asian elephants and the archaeological study, which was made in a specialized workshop context. In this paper we present the archaeological context, the study of the ivory artefacts and th…
Las ánforas de Brindisi en Hispania Citerior. Pautas de distribución y consumo
2017
La presencia del ejército romano republicano en la Hispania Citerior ha sido difícil de reconocer en el pasado debido al error en la interpretación de algunos yacimientos y la falta de investigación sobre el tema. En los últimos años, se han realizado nuevas investigaciones sobre yacimientos romanos republicanos identificando pequeñas fortificaciones militares y asentamientos civiles itálicos relacionados con el ejército. Uno de los fósiles directores presentes en todos estos yacimientos es la cerámica itálica tanto fina como común y las ánforas. Precisamente, las ánforas de la Apulia constituyen uno de los fósiles directores poco estudiados; este artículo pretende llenar este vacío y mostr…
Indigenismo y migracionismo. Aspectos de la neolitización en la fachada oriental de la Península Ibérica
1996
This paper discusses various aspects on the origins of the Neolithic in the Iberian Peninsula. The dual model is proposed as an alternative to the dichotomy of demie (migrationist) and non-demic (indigenist) explanations. The application of this model in eastern Spain offers an opportunity to evaluate its potential to account for diversity in processes associated with the origins of food production and their spatial organisation.
Inferences of dietary preferences of Miocene squirrels (Xerinae, Sciuridae) from the Iberian Peninsula and Namibia using microwear analyses and ename…
2020
In this work, we compared microwear features and enamel thickness from upper molars (M1 and M2) of extinct Xerinae squirrels from the Miocene of Namibia (Vulcanisciurus sp) and the Iberian Peninsula (Atlantoxerus nov. sp. and Heteroxerus rubricati). We also examined the microwear from young and adult specimens of one extant squirrel, Atlantoxerus getulus, to compare it with the extinct species. Both, the microwear features and enamel thickness showed that the Miocene African species presented a more abrasive diet than the Iberian ones.
Comparative assessment of RAMS and WRF short-term forecasts over Eastern Iberian Peninsula using various in-situ observations, remote sensing product…
2018
The Regional Atmospheric Modeling System (RAMS) and the Weather Research and Forecasting (WRF) mesoscale models are being used for weather and air quality studies as well as forecasting tools in Numerical Weather Prediction (NWP) systems. In the current study, we perform a comparative assessment of these models under distinct typical atmospheric conditions, classified according to the dominant wind flow and cloudiness, over Eastern Iberian Peninsula. This study is focused on the model representation of key physical processes in terms of meteorology and surface variables during a 7-days period in summer 2011. The hourly outputs produced by these two models are compared not only with observed…
Integrated remote sensing approach to global agricultural drought monitoring
2018
Abstract This study explores the use of the Soil Moisture Agricultural Drought Index (SMADI) as a global estimator of agricultural drought. Previous research presented SMADI as a novel index based on the joint use of remotely sensed datasets of land surface temperature (LST) and normalized difference vegetation index (NDVI) from the Moderate Resolution Imaging Spectroradiometer (MODIS) together with the surface soil moisture (SSM) from the Soil Moisture and Ocean Salinity (SMOS) mission. This study presents the results of applying SMADI at the global scale with a spatial resolution of 0.05° every 15 days. The period of the study spanned from 2010 to 2015. Three spatial scales (local, region…
Active faulting and continental slope instability in the Gulf of Patti (Tyrrhenian side of NE Sicily, Italy): a field, marine and seismological joint…
2016
The Gulf of Patti and its onshore sector represent one of the most seismically active regions of the Italian Peninsula. Over the period 1984–2014, about 1800 earthquakes with small-to-moderate magnitude and a maximum hypocentral depth of 40 km occurred in this area. Historical catalogues reveal that the same area was affected by several strong earthquakes such as the Mw = 6.1 event in April 1978 and the Mw = 6.2 one in March 1786 which have caused severe damages in the surrounding localities. The main seismotectonic feature affecting this area is represented by a NNW–SSE trending right-lateral strike-slip fault system called ‘‘Aeolian–Tindari–Letojanni’’ (ATLFS) which has been interpreted a…
A component-based approximation for trend detection of intense rainfall in the Spanish Mediterranean coast
2022
Rainfall behavior is a fundamental issue in areas with scarce and irregular amounts, such as the Spanish Mediterranean region. We identified 12 spatial patterns that characterized 899 torrential precipitation events (≥150 mm in 24 h) that occurred in the 3,537 rainy precipitation series in the period 1950–2020. Three of these components––eastern and ESE––showed positive and significant trends in their accumulated volumes. We then characterized the mean synoptic causes of the 10 most intense events in each component at both mean sea-level pressure and 500 hPa geopotential height, and also the integrated water-vapor transport between 1,000 and 300 hPa. We found a clear spatial distribution of…
