Comunicação e prática política nas monarquias ibéricas de antigo regime (1700-1750): Évora, Córdova, Ouro Preto e Quito

O presente estudo trata da prática política nos diferentes espaços das monarquias ibéricas na primeira metade do século XVIII. Tendo como objecto de análise principal a correspondência de quatro municípios seleccionados como observatórios (Évora, Córdova, Ouro Preto e Quito), pretende-se conhecer com maior detalhe as variações desta mesma prática em função dos contextos. Partindo da ideia de que o modelo político-administrativo implementado na América seria, na essência, decalcado do peninsular, procura-se aqui entender as mutações resultantes desta transferência. Ao longo deste trabalho defender-se-á a ideia de que, apesar das semelhanças entre o aparelho burocrático metropolitano e americano, a prática política nos territórios extra-europeus revestia-se de um conjunto de especificidades que a diferenciavam de forma clara. Neste sentido, argumenta-se que estas mutações condicionavam igualmente quais seriam os interlocutores das coroas nas diferentes regiões. Ou seja, que uma mesma instância teria, nos territórios ultramarinos e peninsulares, graus de participação nos processos de negociação e articulação política consideravelmente diferentes, algo que de que os municípios são um bom exemplo. Para o efeito serão comparados aspectos como os ritmos da comunicação; o relevo de cada instância na comunicação com a coroa; o perfil dos indivíduos que, nos diferentes territórios, ocupavam os ofícios da malha administrativa; as dinâmicas de especialização de competências ou de concentração de funções num mesmo cargo; a conflitualidade institucional e a existência de iniciativas políticas de cariz supramunicipal; Abstract: This study deals with the political practice in different areas of the Iberian monarchies in the first half of the eighteenth century. The main object of study is the correspondence of four selected municipalities (Évora, Cordoba, Ouro Preto and Quito), and it aims to know in greater detail the variations of this same practice on different contexts. Starting from the idea that the political and administrative model implemented in America would, in essence, be modeled on the peninsular, the intent is to understand the changes resulting from this transfer. Throughout this work we will argue that, despite the similarities between the metropolitan and American bureaucracy, political practice in non-European territories possessed a set of characteristics that were very specific. In this sense, it is argued that these mutations would also determine which would be the interlocutors of the crowns in different regions. That is, if the same instance would, in the overseas and peninsular territories, have different levels of participation in the negotiation and in the political articulation processes, something that municipalities are a good example of. For this purpose, aspects such as the rhythms of communication; the importance of each instance in the correspondence with the crown; the profile of the individuals who, in different territories, occupied the offices of the administrative network; the dynamics of specialization or concentration of functions in the same position; the institutional conflicts and the existence of supramunicipal initiatives will be compared.

Post-colonial law : legal establishments from past empires are illegitimate

The extant literature covering the plights of indigenous people resident to the African continent consistently targets colonial law as an obstacle to the recognition of indigenous rights. Whereas colonial law is argued to be archaic and in need of review, which it is, this article argues the new perspective that colonial law is illegitimate for ordering the population it presides over – specifically in Africa. It is seen, in five case studies, that post-colonial legal structures have not considered the legitimacy of colonial law and have rather modified a variety of statutes as country contexts dictated. However, the modified statutes are based on an alien theoretical legality, something laden with connotations that hark to older and backward times. It is ultimately argued that the legal structures which underpin ex-colonies in Africa need considerable revision so as to base statutes on African theoretical legality, rather than imperialistic European ones, so as to maximise the law’s legitimacy.

The "Shackleton Site" (IODP Site U1385) on the Iberian Margin

Nick Shackleton’s research on piston cores from the Iberian margin highlighted the importance of this region for providing high-fidelity records of millennial-scale climate variability, and for correlating climate events from the marine environment to polar ice cores and European terrestrial sequences. During the Integrated Ocean Drilling Program (IODP) Expedition 339, we sought to extend the Iberian margin sediment record by drilling with the D/V JOIDES Resolution. Five holes were cored at Site U1385 using the advanced piston corer (APC) system to a maximum depth of ∼ 155.9 m below sea floor (m b.s.f.). Immediately after the expedition, cores from all holes were analyzed by core scanning X-ray fluorescence (XRF) at 1 cm spatial resolution. Ca/Ti data were used to accurately correlate from hole-to-hole and construct a composite spliced section, containing no gaps or disturbed intervals to 166.5 m composite depth (mcd). A low-resolution (20 cm sample spacing) oxygen isotope record confirms that Site U1385 contains a continuous record of hemipelagic sedimentation from the Holocene to 1.43 Ma (Marine Isotope Stage 46). The sediment profile at Site U1385 extends across the middle Pleistocene transition (MPT) with sedimentation rates averaging ∼ 10 cm kyr−1. Strongprecession cycles in colour and elemental XRF signals provide a powerful tool for developing an orbitally tuned reference timescale. Site U1385 is likely to become an important type section for marine–ice–terrestrial core correlations and the study of orbital- and millennial-scale climate variability.

Phylogeography and demographic history of Lacerta lepida in the Iberian Peninsula

The Iberian Peninsula is recognized as an important refugial area for species survival and diversification during the climatic cycles of the Quaternary. Recent phylogeographic studies have revealed Iberia as a complex of multiple refugia. However, most of these studies have focused either on species with narrow distributions within the region or species groups that, although widely distributed, generally have a genetic structure that relates to pre-Quaternary cladogenetic events. In this study we undertake a detailed phylogeographic analysis of the lizard species, Lacerta lepida, whose distribution encompasses the entire Iberian Peninsula. We attempt to identify refugial areas, recolonization routes, zones of secondary contact and date demographic events within this species. Results support the existence of 6 evolutionary lineages (phylogroups) with a strong association between genetic variation and geography, suggesting a history of allopatric divergence in different refugia. Diversification within phylogroups is concordant with the onset of the Pleistocene climatic oscillations. The southern regions of several phylogroups show a high incidence of ancestral alleles in contrast with high incidence of recently derived alleles in northern regions. All phylogroups show signs of recent demographic and spatial expansions. We have further identified several zones of secondary contact, with divergent mitochondrial haplotypes occurring in narrow zones of sympatry. The concordant patterns of spatial and demographic expansions detected within phylogroups, together with the high incidence of ancestral haplotypes in southern regions of several phylogroups, suggests a pattern of contraction of populations into southern refugia during adverse climatic conditions from which subsequent northern expansions occurred. This study supports the emergent pattern of multiple refugia within Iberia but adds to it by identifying a pattern of refugia coincident with the southern distribution limits of individual evolutionary lineages. These areas are important in terms of long-term species persistence and therefore important areas for conservation.

Analysis of volatility transmissions in integrated and interconnected markets: The case of the Iberian and French markets

This paper models the mean and volatility spillovers of prices within the integrated Iberian and the interconnected Spanish and French electricity markets. Using the constant (CCC) and dynamic conditional correlation (DCC) bivariate models with three different specifications of the univariate variance processes, we study the extent to which increasing interconnection and harmonization in regulation have favoured price convergence. The data consist of daily prices calculated as the arithmetic mean of the hourly prices over a span from July 1st 2007 until February 29th 2012. The DCC model in which the variances of the univariate processes are specified with a VARMA(1,1) fits the data best for the integrated MIBEL whereas a CCC model with a GARCH(1,1) specification for the univariate variance processes is selected to model the price series in Spain and France. Results show that there are significant mean and volatility spillovers in the MIBEL, indicating strong interdependence between the two markets, while there is a weaker evidence of integration between the Spanish and French markets. We provide new evidence that the EU target of achieving a single electricity market largely depends on increasing trade between countries and homogeneous rules of market functioning.

Trace element concentrations in muscle tissue of the benthopelagic grenadier (Coryphaenoides armatus) from the Iberian deep-sea

11 specimens of Coryphaenoides armatus were collected at former dumping sites for radioactive material in the Iberian deep sea at a depth of 4700 m and their muscle tissue was analysed for four trace elements (copper, zinc, cadmium and lead) by differential pulse anodic stripping voltammetry (DPSAV). Concentrations of zinc were typical for fish muscle in general; copper content was somewhat higher than generally found in fish. The cadmium and lead contents were at a level found in fish from the open sea but the lead content of 2 specimens taken in area East-B was found to be higher.

Novel Papillomaviruses in Free-Ranging Iberian Bats: No Virus-Host Co-evolution, No Strict Host Specificity, and Hints for Recombination

Papillomaviruses (PVs) are widespread pathogens. However, the extent of PV infections in bats remains largely unknown. This work represents the first comprehensive study of PVs in Iberian bats. We identified four novel PVs in the mucosa of free-ranging Eptesicus serotinus (EserPV1, EserPV2, and EserPV3) and Rhinolophus ferrumequinum (RferPV1) individuals and analyzed their phylogenetic relationships within the viral family. We further assessed their prevalence in different populations of E. serotinus and its close relative E. isabellinus. Although it is frequent to read that PVs co-evolve with their host, that PVs are highly species-specific, and that PVs do not usually recombine, our results suggest otherwise. First, strict virus-host co-evolution is rejected by the existence of five, distantly related bat PV lineages and by the lack of congruence between bats and bat PVs phylogenies. Second, the ability of EserPV2 and EserPV3 to infect two different bat species (E. serotinus and E. isabellinus) argues against strict host specificity. Finally, the description of a second noncoding region in the RferPV1 genome reinforces the view of an increased susceptibility to recombination in the E2-L2 genomic region. These findings prompt the question of whether the prevailing paradigms regarding PVs evolution should be reconsidered.

Degeneration of postovulatory follicles in the Iberian sardine Sardina pilchardus: structural changes and factors affecting resorption

Inaccuracy in the aging of postovulatory follicles (POFs) and in estimating the effect of temperature on the resorption rate of POFs may introduce bias in the determination of the daily spawning age classes with the daily egg production method (DEPM). To explore the above two bias problems with f ield-collected European pilchard (Sardina pilchardus, known regionally as the Iberian sardine), a method was developed in which the time elapsed from spawning (POF age) was estimated from the size of POFs (i.e., from the cross-sectional area in histological sections). The potential effect of the preservative type and embedding material on POF size and the effect of ambient water temperature on POF resorption rate are taken into account with this method. A highly significant loglinear relationship was found between POF area and age; POF area shrank by approximately 50% per day. POFs were also shown to shrink faster at higher temperatures (approximately 3% per degree), but this temperature effect is unlikely to be an important source of bias in the assignment of females to daily spawning classes. The embedding material was also shown to influence the size of POFs, the latter being significantly larger in resin than in paraffin sections. In conclusion, the size of POFs provides an indirect, reliable estimation of the time elapsed from spawning and may thus be used to test both the validity of POF staging criteria for identifying daily classes of spawners and the effect of other factors (such as temperature and laboratory processing) in applications of the DEPM to S. pilchardus and other fish species.
