Essa dissertação faz uma introdução aos aspectos arqueológicos e literários de Moab, temática carente de publicações em língua portuguesa. Trata, primeiramente, dos fatos relacionados à descoberta da inscrição de Mesa na segunda metade do século 19, das disputas diplomáticas que ocasionaram a destruição da inscrição, bem como das obras científicas que, durante as décadas seguintes, abordaram o assunto. Na seqüência, apresenta as principais características geográficas e arqueológicas de Moab, durante as Idades do Bronze Recente, do Ferro Antigo e do Ferro Recente, dando especial atenção aos assentamentos humanos, mas também às grandes construções e às esculturas, consideradas recursos culturais necessários ao estado moabita, patrimonial e segmentário, que fazia uso de metáforas domésticas para referendar sua hegemonia; além do mais, apresenta o lugar de Moab no mundo assírio, e sua importância como rota comercial. A tradução da estela de Mesa, os comentários filológicos e a análise da sua forma e do seu gênero literário, apontam para um texto elaborado a partir de ferramentas literárias claras, utilizado para marcar o poder da monarquia moabita. Tais aspectos arqueológicos e literários sustentam que o desenvolvimento de Moab ocorreu após o fim da dominação do Israel omrida, além de sugerirem um novo olhar sobre a Bíblia Hebraica.(AU)

Os produtos provenientes do mar têm um importante papel a nível socioeconómico, gastronómico e no legado cultural das comunidades piscatórias e costeiras de Portugal. O Percebe Pollicipes pollicipes é na Península Ibérica o recurso biológico do intertidal mais explorado pelo ser humano, devido à sua enorme popularidade e consequente procura, fazendo em algumas ocasiões disparar o preço de mercado até 150€/kg, gerando na sobreexploração dos stocks existentes. No entanto, na área marinha protegida da Reserva Natural da Berlenga, a apanha do percebe é fortemente regulada, tendo-se tornado em Portugal num bom exemplo da gestão de recursos marinhos. Com o intuito de prevenir fraudes, adulteração alimentar ou quaisquer outras práticas que possam induzir o consumidor em erro a Comissão Europeia declara que, o consumidor tem o direito de receber informação correcta acerca dos produtos que adquire, para além de definir regras para a correcta aplicação destas regras. Métodos analíticos que possibilitem identificar a origem do percebe, tornam-se deste modo importantes ferramantas no desenvolvimento de um selo de Denominação de Origem Protegida (DOP) e na gestão comercial do produto. Deste modo, investigou-se se o Percebe possui diferenças específicas de cada local de captura, através da forma da unha (CS), da composição microquímica da unha (EM) e do perfil de ácidos gordos (FA). A análise foi efectuada em indivíduos recolhidos em 3 locais na Reserva Natural das Berlengas e 7 ao longo de 300 km da costa Portuguesa. Em cada indivíduo analisou-se a forma da unha (CS) através da morfometria geométrica, a composição microquímica da unha (EM) através de ICP-MS e o perfil de ácidos gordos do músculo através de GC-FID. A análise das funções discriminantes (DFA) quer para a EM quer para a FA em separado obteve um elevado sucesso de reclassificação (77,6 % e 99% respectivamente, através de validação cruzada), enquanto que EM combinado com FA permitiu um sucesso de reclassificação de 100 %. A análise discriminante baseada apenas na CS, demonstrou um baixo sucesso (29,6 %) .Estes resultados demonstram que a composição microquímica da unha e o perfil de ácidos gordos do músculo de Percebe, poderá ser uma ferramenta de elevada importância, na determinação da origem do Percebe. Esta abordagem poderá ser utilizada para identificar a origem dos percebes comercializados, bem como ajudar no desenvolvimento de um selo DOP, aumentando ao mesmo tempo o valor potencial dos recursos biológicos provenientes de áreas marinhas protegidas em Portugal.

Previous studies about the strength of the lithosphere in the Iberia centre fail to resolve the depth of earthquakes because of the rheological uncertainties. Therefore, new contributions are considered (the crustal structure from a density model) and several parameters (tectonic regime, mantle rheology, strain rate) are checked in this paper to properly examine the role of lithospheric strength in the intraplate seismicity and the Cenozoic evolution. The strength distribution with depth, the integrated strength, the effective elastic thickness and the seismogenic thickness have been calculated by a finite element modelling of the lithosphere across the Central System mountain range and the bordering Duero and Madrid sedimentary basins. Only a dry mantle under strike-slip/extension and a strain rate of 10-15 s-1, or under extension and 10-16 s-1, causes a strong lithosphere. The integrated strength and the elastic thickness are lower in the mountain chain than in the basins. These anisotropies have been maintained since the Cenozoic and determine the mountain uplift and the biharmonic folding of the Iberian lithosphere during the Alpine deformations. The seismogenic thickness bounds the seismic activity in the upper–middle crust, and the decreasing crustal strength from the Duero Basin towards the Madrid Basin is related to a parallel increase in Plio–Quaternary deformations and seismicity. However, elasto–plastic modelling shows that current African–Eurasian convergence is resolved elastically or ductilely, which accounts for the low seismicity recorded in this region.

Several vertebrae of a sauropterygian specimen have been recovered in Fuencaliente de Medinaceli (Soria Province, Castilla y León, Spain). The remains come from Middle–Upper Triassic Muschelkalk Facies. This finding represents the first documented evidence of a Triassic tetrapod in Castilla y León. The vertebrae belong to Nothosaurus, a sauropterygian genus found in Europe, Middle East, North of Africa and China. This genus is poorly-known in the Iberian record. The new remains constitute the first evidence of the species Nothosaurus giganteus, or a related taxon, in the Iberian Peninsula. This study reveals the occurrence of at least two species of the sauropterygian Nothosaurus in the Spanish record.

Fossil associations from the middle and upper Eocene (Bartonian and Priabonian) sedimentary succession of the Pamplona Basin are described. This succession was accumulated in the western part of the South Pyrenean peripheral foreland basin and extends from deep-marine turbiditic (Ezkaba Sandstone Formation) to deltaic (Pamplona Marl, Ardanatz Sandstone and Ilundain Marl formations) and marginal marine deposits (Gendulain Formation). The micropalaeontological content is high. It is dominated by foraminifera, and common ostracods and other microfossils are also present. The fossil ichnoasssemblages include at least 23 ichnogenera and 28 ichnospecies indicative of Nereites, Cruziana, Glossifungites and ?Scoyenia-Mermia ichnofacies. Body macrofossils of 78 taxa corresponding to macroforaminifera, sponges, corals, bryozoans, brachiopods, annelids, molluscs, arthropods, echinoderms and vertebrates have been identified. Both the number of ichnotaxa and of species (e. g. bryozoans, molluscs and condrichthyans) may be considerably higher. Body fossil assemblages are comparable to those from the Eocene of the Nord Pyrenean area (Basque Coast), and also to those from the Eocene of the west-central and eastern part of South Pyrenean area (Aragon and Catalonia). At the European scale, the molluscs assemblages seem endemic from the Pyrenean area, although several Tethyan (Italy and Alps) and Northern elements (Paris basin and Normandy) have been recorded. Palaeontological data of studied sedimentary units fit well with the shallowing process that throughout the middle and late Eocene occurs in the area, according to the sedimentological and stratigraphical data.

The study of the Upper Jurassic-Lower Cretaceous deposits (Higueruelas, Villar del Arzobispo and Aldea de Cortés Formations) of the South Iberian Basin (NW Valencia, Spain) reveals new stratigraphic and sedimentological data, which have significant implications on the stratigraphic framework, depositional environments and age of these units. The Higueruelas Fm was deposited in a mid-inner carbonate platform where oncolitic bars migrated by the action of storms and where oncoid production progressively decreased towards the uppermost part of the unit. The overlying Villar del Arzobispo Fm has been traditionally interpreted as an inner platform-lagoon evolving into a tidal-flat. Here it is interpreted as an inner-carbonate platform affected by storms, where oolitic shoals protected a lagoon, which had siliciclastic inputs from the continent. The Aldea de Cortés Fm has been previously interpreted as a lagoon surrounded by tidal-flats and fluvial-deltaic plains. Here it is reinterpreted as a coastal wetland where siliciclastic muddy deposits interacted with shallow fresh to marine water bodies, aeolian dunes and continental siliciclastic inputs. The contact between the Higueruelas and Villar del Arzobispo Fms, classically defined as gradual, is also interpreted here as rapid. More importantly, the contact between the Villar del Arzobispo and Aldea de Cortés Fms, previously considered as unconformable, is here interpreted as gradual. The presence of Alveosepta in the Villar del Arzobispo Fm suggests that at least part of this unit is Kimmeridgian, unlike the previously assigned Late Tithonian-Middle Berriasian age. Consequently, the underlying Higueruelas Fm, previously considered Tithonian, should not be younger than Kimmeridgian. Accordingly, sedimentation of the Aldea de Cortés Fm, previously considered Valangian-Hauterivian, probably started during the Tithonian and it may be considered part of the regressive trend of the Late Jurassic-Early Cretaceous cycle. This is consistent with the dinosaur faunas, typically Jurassic, described in the Villar del Arzobispo and Aldea de Cortés Fms.

The Museu Geológico collections house some of the first sauropod references of the Lusitanian Basin Upper Jurassic record, including the Lourinhasaurus alenquerensis and Lusotitan atalaiensis lectotypes, previously considered as new species of the Apatosaurus and Brachiosaurus genera, respectively. Several fragmentary specimens have been classical referred to those taxa, but the most part of these systematic attributions are not supported herein, excluding a caudal vertebra from Maceira (MG 8804) considered as cf. Lusotitan atalaiensis. From the material housed in the Museu Geológico were identified basal eusauropods (indeterminate eusauropods and turiasaurs) and neosauropods (indeterminate neosauropods, diplodods and camarasaurids and basal titanosauriforms). Middle caudal vertebrae with lateral fossae, ventral hollow border by pronounced ventrolateral crests and quadrangular cross-section suggest for the presence of diplodocine diplodocids in north area of the Lusitanian Basin Central Sector during the Late Jurassic. A humerus collected from Praia dos Frades (MG 4976) is attributed to cf. Duriatitan humerocristatus suggesting the presence of shared sauropod forms between the Portugal and United Kingdom during the Late Jurassic. Duriatitan is an indeterminate member of Eusauropoda and the discovery of new material in both territories is necessary to confirm this systematic approach. The studied material is in according with the previous recorded paleobiodiversity for the sauropod clade during the Portuguese Late Jurassic, which includes basal eusauropods (including turiasaurs), diplodocids and macronarians (including camarasaurids and basal titanosauriforms).

As a result of a floristic survey carried out in riparian habitats of northern Spain, new chorological data are provided for 9 alien and 6 native plant species. Some species are reported for the first time at regional scale, such as Carex strigosa, Helianthus x laetiflorus and Persicaria pensylvanica in Cantabria. Also noteworthy is the finding of naturalised populations of the North American grass Muhlenbergia schreberi at the Urumea river basin, which represents the second reference for the Iberian Peninsula.
