Late holocene benthic Foraminifera of the Roman Lacus ligustinus (SW Spain): a ...
Guerra, Liliana; Veiga-Pires, Cristina; Luz Gonzalez Regalado, M. L.; Abad, M.; Toscano, A.; Manuel Munoz, J. M.; Ruiz, F.; Vidal, J. R.; Caceres, L. M.This paper studies the Late Holocene benthic foraminifera from a continuous core extracted in the Doliana National Park (SW Spain). In this core, the foraminiferal assemblages confirm the Late Holocene lagoon (historically so-called Locus Ligustinus) during the Roman period, about 2000 years ago. The more open, deepest areas of this lagoon were dominated by Ammonia tepida and Elphidium spp., while Haynesina ger...
Heated flint TL-dating for Gruta da Oliveira (Portugal): dosimetric challenges ...
Richter, D.; Angelucci, D.E.; Dias, M.I.; Prudêncio, M.I.; Gouveia, M.A.; Cardoso, G.J.; Burbidge, C.I.; Zilhão, JoãoThe Mousterian stratigraphy of Gruta da Oliveira (Torres Novas, Portugal) contains one of the latest occupations by Neanderthals on the Iberian Peninsula. Thermoluminescence (TL) dates on heated flints were obtained for layers 13 and 14, and compared with the radiocarbon (charcoal and burnt bone) and U/ Th (secondary carbonates) dating results available for those layers and the succession as a whole. As the int...
Análise Espácio-Temporal de Fogos Florestais em Portugal
Dias, M.I.; Silva, G.Na última década, os incêndios florestais tornaram-se uma das catástrofes naturais mais graves em Portugal. O elevado número de ocorrências e a sua severidade provocam grande devastação levando a elevados prejuízos, quer económicos quer ambientais, e colocando em risco bens, populações e a subsistência da própria floresta. Neste trabalho apresentam-se modelos hierárquicos bayesianos para analisar dados espaço-t...
Spatio-temporal Analysis of Forest Fires
Dias, M.I.; Silva, G.In the last decade, forest res have become one of the worst natural disasters in Portugal, causing great forest devastation, leading to both economic and environmental losses and putting at risk populations and the livelihoods of the forest itself. In this paper we present Bayesian hierarchical models to analyze spatio- temporal re data on the proportion of burned area in Portugal, by municipalities and over th...
Análise Bayesiana do Efeito da Poluição Atmosférica na Admissão Hospitalar de C...
Dias, M.I.; Silva, G.; Louro, C.Air pollution is a serious environmental problem, causing adverse e ects such as respiratory disorders, allergies and, in more serious situations, degenerative lesions in the nervous system and vital organs, especially in children and the elderly. In most polluted cities, such disturbances become worse in winter with the usual low temperatures and high humidity level. Generalized linear models and generalized a...
