Cross-shore transport in a daily varying upwelling regime: A case study of barnacle larvae on the southwestern Iberian coast.

With favored offshore and downstream advection, the question of which physical mechanism may promote onshore transport of larvae in upwelling systems is of central interest. We have conducted a semi-realistic high resolution (0.25 km) numerical study of Lagrangian transports across the inner-shelf under upwelling-favorable wind forcing conditions, focusing on the shelf area of the Southwestern Portuguese coast, in the lee of Cape Sines. We add our findings to several years of biological observations of C. montagui, a planktonic species with higher recruitment during the upwelling peak timely with the daylight flood. Simulations cover a fifteen days period during the summer of 2006. We focused on Spring and Neap tide periods and observed upfront differences between simulations and the in situ observa- tions. However, the model is capable of representing the main dynamics of the region, namely the re- petitive character of the inner-shelf currents. We find that the cross-shore flow varies significantly in the daily cycle, and locally within a scale of a few kilometers in association with local topography and the presence of the cape. We consider the region immediately in the lee of the cape to be an upwelling shadow where the larvae became retained, and found that tidally tied migration proves beneficial for successful recruitment during the spring tides period. Our work suggested that the wind is not the only mechanism responsible for the daily variability of the cross-shore exchange. However, its sharp reversal at midday is critical for the advection of larvae towards the coast.

Technological characterization of molded islamic pottery from Iberian Peninsula

The thesis examines the technical aspects of unglazed molded ceramics from Mértola, in the context of Islamic archaeology of the Iberian Peninsula (Almohad period, end of 12th and the beginning of 13th century). Ceramics of the time period under discussion (12th – 13th century) are understudied, including in what concern to shaping and firing of ceramic vessels, the origin of raw materials used in ceramics and glazes, and decoration methods such as slip painting and/or colored glazes. Moreover, the use of archaeometry tools is rare. Along with providing a general picture of molded ceramic production in Mértola, this work provides a new dimension to the discipline of Islamic ceramic studies by the analytical tool used and demonstrating the importance of archaeological ceramics of the western peripheries to the understanding the production of ceramics and the transmission of knowledge and cultural traditions within the Islamic caliphate. The chemical and mineralogical characterization of 12th/13th century Almohad unglazed molded ware from Mértola was accomplished through multi – analytical approach combining SEM, Powder/uXRD and LA-ICP-MS methods. In this paper unglazed and glazed samples were analyzed but the attention was given to unglazed specimens, while the glazed samples were used for the comparison with the previous group in order to determine possible similarities or dissimilarities, thus providing enough data to discuss about technical aspects and potential provenance; Resumo: A tese debruça-se sobre os aspetos técnicos de cerâmica de molde não-vidrada de Mértola, no contexto da arqueologia islâmica da Península Ibérica (período Almóada, final de XII e início do século XIII). A cerâmica do período em discussão (séculos XII-XIII) é pouco estudada inclusive no que concerne ao fabrico e à cozedura, à de fonte de matérias-primas, na pasta ou nos esmaltes e aos métodos de decoração, como pintura, presença de engobes ou esmaltes. Além disso, o uso de ferramentas de Arqueometria é raro. Para fornecer uma visão geral da produção de cerâmica moldada em Mértola, este trabalho oferece uma nova dimensão para a disciplina de cerâmica islâmicas pelas ferramentas analíticas utilizadas. Demonstrando a importância da cerâmica arqueológica da periferia ocidental para a compreensão da produção cerâmica e a transmissão de conhecimentos e tradições culturais no califado islâmico. A caracterização mineralógica e química das cerâmicas de molde e não-vidrada, Almóada, dos séculos XII-XIII de Mértola foi realizada através de uma abordagem multi-analítica que combina métodos de SEM-EDS, uXRD e LA-ICP-MS. Neste trabalho, as cerâmicas vidradas e não-vidradas foram analisadas conjuntamente, dando mais atenção aos espécimes não vidrados. As amostras de cerâmicas vidradas foram utilizados para a comparação com o grupo anterior, a fim de determinar as possíveis semelhanças ou diferenças, proporcionando, assim, dados suficientes para discutir os aspetos técnicos e o potencial de proveniência das cerâmicas não vidradas

Iberian and Latin American Music Scholarship on the Ascent: Reflections from the United States

In the early twentieth century, musicology was established as an academic discipline in the United States. Nonetheless, with the exception of Iberian medieval and Renaissance repertories, U.S. scholars largely overlooked the music of the Spanish- and Portuguese- speaking world. Why should this have been the case, especially in light of Spain’s strong historical presence in the United States? This autobiographical essay examines this question by tracing the career of an individual musicologist, the Hispanist musicologist Carol A. Hess. Evaluated here are disciplinary shifts in U.S. musicology —methodological, philosophical, and ideological— over the past thirty years. These transformations have combined to make this repertory a viable field of study today. Musicologists in the United States can now make their careers by specializing in Iberian and Latin American music, as well as the music of the Hispanic diaspora. They research topics ranging from the avant-garde composer Llorenç Barber to the rapper Nach Scratch or the popular bandleader Xavier Cugat and his U.S. audiences of the 1940s, while others also pursue the time-tested areas of medieval and Renaissance music. Iberian and Latin American music is regularly offered in postsecondary institutions while instructors now have a variety of textbooks and other pedagogical resources from which to choose. All add up to a disciplinary freedom that would have been unthinkable only a few decades ago.

O saber Kamaiurá sobre a saúde do corpo

Os Kamaiurá são um povo de língua Tupi que, juntamente com povos das famílias linguísticas Aruak, Karib, Tupi e da língua isolada Trumai, habita o Alto Xingu (MT). A homogeneidade cultural entre esses povos é evidenciada em múltiplos aspectos, como forma e disposição das aldeias, tipo de habitação, hábitos alimentares, reclusão pubertária, pinturas e adornos corporais, uso do uluri pelas mulheres, festas e cerimônias, como o Kwaryp. Esse padrão cultural comum resulta da longa ocupação de uma mesma área geográfica e da frequência de casamentos interétnicos. O presente trabalho mostra como o saber sobre a saúde do corpo é construído a partir de elementos que compõem a visão do mundo Kamaiurá, em que observação, experimentação e mitologia se conjugam. Descreve os cuidados dispensados ao corpo e as regras culturais e espirituais relativos às diferentes etapas do ciclo vital.

The historiographic Hispano-Americanism: Spain and America in the perspective of Ricardo Levene and Rafael Altamira

This article analyzes how Latin American history was interpreted by two eminent historians, the Argentine Ricardo Levene and the Spaniard Rafael Altamira. It discusses how their paths crossed in the advocacy of Hispano-Americanism as a political project and interpretive horizon of Iberian and American history.

Dating the dreaming? Creation of myths and rituals for mounds along the northern Australian coastline

Shell mounds ceased to be built in many parts of coastal northern Australia about 800-600 years ago. They are the subject of stories told by Aboriginal people and some have been incorporated in ritual and political activities during the last 150 ears. These understandings emerged only after termination of the economic and environmental system that created them, 800-600 years ago, in a number of widely separated coastal regions, Modern stories and treatments of these mounds by Aboriginal people concern modern or near-modern practices. Modern views of the mounds, their mythological and ritual associations, may be explained by reference to the socioeconomic transitions seen in the archaeological record; but the recent cultural, social and symbolic statements about these places cannot inform us of the process or ideology concerned with the formation of the mounds. Many Aboriginal communities over the last half a millennium actively,formed understandings of new landscapes and systems of land use. Attempts to impose historic ideologies and cosmologies on earlier times fail to acknowledge the magnitude and rate of economic and ideological change on the tropical coastline of Australia.

The GHEP-EMPOP collaboration on mtDNA population data-A new resource for forensic casework

Mitochondrial DNA (mtDNA) population data for forensic purposes are still scarce for some populations, which may limit the evaluation of forensic evidence especially when the rarity of a haplotype needs to be determined in a database search. In order to improve the collection of mtDNA lineages from the Iberian and South American subcontinents, we here report the results of a collaborative study involving nine laboratories from the Spanish and Portuguese Speaking Working Group of the International Society for Forensic Genetics (GHEP-ISFG) and EMPOP. The individual laboratories contributed population data that were generated throughout the past 10 years, but in the majority of cases have not been made available to the scientific community. A total of 1019 haplotypes from Iberia (Basque Country, 2 general Spanish populations, 2 North and 1 Central Portugal populations), and Latin America (3 populations from Sao Paulo) were collected, reviewed and harmonized according to defined EMPOP criteria. The majority of data ambiguities that were found during the reviewing process (41 in total) were transcription errors confirming that the documentation process is still the most error-prone stage in reporting mtDNA population data, especially when performed manually. This GHEP-EMPOP collaboration has significantly improved the quality of the individual mtDNA datasets and adds mtDNA population data as valuable resource to the EMPOP database (www.empop.org).

The history and value of the elephant in Sri Lankan society

Reviews the literature to provide an overview of the historical significance of the elephant in Sri Lankan society, an association which dates back more than 4,000 years. The present status of this relationship assessed on the basis of the findings of a recent study undertaken on the total economic value of elephants in Sri Lanka. This paper, first briefly outlines the history, evolution, nature and their distribution of the Asian elephant while providing some insights on the status of the elephant (Elephas maxima maxima) in Sri Lanka. Next, it reviews the literature in order to assess the historical affiliation that the elephant has maintained with the Sri Lankan society, its culture, history, mythology and religion. The empirical evidence on the economic value of conservation of the remaining elephant population in Sri Lanka is reviewed and the Sri Lankan people’s attitudes towards conserving this species of wildlife. Literature reviewed and analysis undertaken indicates that the elephant in Sri Lanka, still, as in the past has a special place in Sri Lankan society, particularly, in its culture, religion and value system. Thus, there is a strong case for ensuring the survival of wild elephant population in Sri Lanka. Furthermore, it also suggests that the community as a whole will experience a net benefit from ensuring the survival of wild elephants in Sri Lanka.

Different mineralization styles in a volcanic-hosted ore deposit: the fluid and isotopic signatures of the Mt Morgan Au-Cu deposit, Australia

Quantitative laser ablation (LA)-ICP-MS analyses of fluid inclusions, trace element chemistry of sulfides, stable isotope (S), and Pb isotopes have been used to discriminate the formation of two contrasting mineralization styles and to evaluate the origin of the Cu and Au at Mt Morgan. The Mt Morgan Au-Cu deposit is hosted by Devonian felsic volcanic rocks that have been intruded by multiple phases of the Mt Morgan Tonalite, a low-K, low-Al2O3 tonalite-trondhjemite-dacite (TTD) complex. An early, barren massive sulfide mineralization with stringer veins is conforming to VHMS sub-seafloor replacement processes, whereas the high-grade Au-Cu. ore is associated with a later quartz-chalcopyrite-pyrite stock work mineralization that is related to intrusive phases of the Tonalite complex. LA-ICP-MS fluid inclusion analyses reveal high As (avg. 8850 ppm) and Sb (avg. 140 ppm) for the Au-Cu mineralization and 5 to 10 times higher Cu concentration than in the fluids associated with the massive pyrite mineralization. Overall, the hydrothermal system of Mt Morgan is characterized by low average fluid salinities in both mineralization styles (45-80% seawater salinity) and temperatures of 210 to 270 degreesC estimated from fluid inclusions. Laser Raman Spectroscopic analysis indicates a consistent and uniform array Of CO2-bearing fluids. Comparison with active submarine hydrothermal vents shows an enrichment of the Mt Morgan fluids in base metals. Therefore, a seawater-dominated fluid is assumed for the barren massive sulfide mineralization, whereas magmatic volatile contributions are implied for the intrusive related mineralization. Condensation of magmatic vapor into a seawater-dominated environment explains the CO2 occurrence, the low salinities, and the enriched base and precious metal fluid composition that is associated with the Au-Cu. mineralization. The sulfur isotope signature of pyrite and chalcopyrite is composed of fractionated Devonian seawater and oxidized magmatic fluids or remobilized sulfur from existing sulfides. Pb isotopes indicate that Au and Cu. originated from the Mt Morgan intrusions and a particular volcanic strata that shows elevated Cu background. (C) 2002 Elsevier Science B.V. All rights reserved.

Gene flow in great bustard populations across the Strait of Gibraltar as elucidated from excremental PCR and mtDNA sequencing

Recent advances in molecular biology have made it possible to use the trace amounts of DNA in faeces to non-invasively sample endangered species for genetic studies. Here we use faeces as a source of DNA and mtDNA sequence data to elucidate the relationship among Spanish and Moroccan populations of great bustards. 834 bp of combined control region and cytochrome-b mtDNA fragments revealed four variable sites that defined seven closely related haplotypes in 54 individuals. Morocco was fixed for a single mtDNA haplotype that occurs at moderate frequency (28%) in Spain. We could not differentiate among the sampled Spanish populations of Caceres and Andalucia but these combined populations were differentiated from the Moroccan population. Estimates of gene flow (Nm = 0.82) are consistent with extensive observations on the southern Iberian peninsular indicating that few individuals fly across the Strait of Gibraltar. We demonstrate that both this sea barrier and mountain barriers in Spain limit dispersal among adjacent great bustard populations to a similar extent. The Moroccan population is of high ornithological significance as it holds the only population of great bustards in Africa. This population is critically small and genetic and observational data indicate that it is unlikely to be recolonised via immigration from Spain should it be extirpated. In light of the evidence presented here it deserves the maximum level of protection.

Revisão dos parasitas e outros agentes infecciosos que afectam as populações ibéricas de um carnívoro social - o texugo euroasiático (Meles Meles, Linnaeus 1758)

O texugo euroasiático é um dos carnívoros ibéricos passível de funcionar como reservatório de algumas zoonoses que podem afectar os animais domésticos, outros animais silvestres ou o Homem, cuja ecologia (ex. sociabilização) promove a manutenção e dispersão de algumas patologias. A listagem dos parasitas e das doenças infecciosas que afectam este predador na Europa foi já profundamente detalhada, mas nesses trabalhos há uma ausência quase completa de referências às populações ibéricas. Assim, o presente estudo tem como objectivo efectuar uma revisão bibliográfica dos trabalhos que mencionem o texugo como hospedeiro de ectoparasitas ou reservatório de outros agentes infecciosos, nomeadamente, pulgas (ex. Pulex), carraças (ex. Ixodes), piolhos (ex. Trichodectes),helmintos (ex. Mastophorus), bactérias (ex. Mycobacterium) e protozoários (ex. Toxoplama).

Impact of a 1755-like tsunami in Huelva, Spain

Coastal areas are highly exposed to natural hazards associated with the sea. In all cases where there is historical evidence for devastating tsunamis, as is the case of the southern coasts of the Iberian Peninsula, there is a need for quantitative hazard tsunami assessment to support spatial planning. Also, local authorities must be able to act towards the population protection in a preemptive way, to inform 'what to do' and 'where to go' and in an alarm, to make people aware of the incoming danger. With this in mind, we investigated the inundation extent, run-up and water depths, of a 1755-like event on the region of Huelva, located on the Spanish southwestern coast, one of the regions that was affected in the past by several high energy events, as proved by historical documents and sedimentological data. Modelling was made with a slightly modified version of the COMCOT (Cornell Multi-grid Coupled Tsunami Model) code. Sensitivity tests were performed for a single source in order to understand the relevance and influence of the source parameters in the inundation extent and the fundamental impact parameters. We show that a 1755-like event will have a dramatic impact in a large area close to Huelva inundating an area between 82 and 92 km(2) and reaching maximum run-up around 5 m. In this sense our results show that small variations on the characteristics of the tsunami source are not too significant for the impact assessment. We show that the maximum flow depth and the maximum run-up increase with the average slip on the source, while the strike of the fault is not a critical factor as Huelva is significantly far away from the potential sources identified up to now. We also show that the maximum flow depth within the inundated area is very dependent on the tidal level, while maximum run-up is less affected, as a consequence of the complex morphology of the area.
