Molecular phylogeography of the Woodland Ringlet (Erebia medusa [Denis and Schiffermüller] 1775) in Europe

Phylogeography is a recent field of biological research that links phylogenetics to biogeography through deciphering the imprint that evolutionary history has left on the genetic structure of extant populations. During the cold phases of the successive ice ages, which drastically shaped species’ distributions since the Pliocene, populations of numerous species were isolated in refugia where many of them evolved into different genetic lineages. My dissertation deals with the phylogeography of the Woodland Ringlet (Erebia medusa [Denis and Schiffermüller] 1775) in Central and Eastern Europe. This Palaearctic butterfly species is currently distributed from central France and south eastern Belgium over large parts of Central Europe and southern Siberia to the Pacific. It is absent from those parts of Europe with mediterranean, oceanic and boreal climates. It was supposed to be a Siberian faunal element with a rather homogeneous population structure in Central Europe due to its postglacial expansion out of a single eastern refugium. An already existing evolutionary scenario for the Woodland Ringlet in Central and Eastern Europe is based on nuclear data (allozymes). To know if this is corroborated by organelle evolutionary history, I sequenced two mitochondrial markers (part of the cytochrome oxydase subunit one and the control region) for populations sampled over the same area. Phylogeography largely relies on the construction of networks of uniparentally inherited haplotypes that are compared to geographic haplotype distribution thanks to recent developed methods such as nested clade phylogeographic analysis (NCPA). Several ring-shaped ambiguities (loops) emerged from both haplotype networks in E. medusa. They can be attributed to recombination and homoplasy. Such loops usually avert the straightforward extraction of the phylogeographic signal contained in a gene tree. I developed several new approaches to extract phylogeographic information in the presence of loops, considering either homoplasy or recombination. This allowed me to deduce a consistent evolutionary history for the species from the mitochondrial data and also adds plausibility for the occurrence of recombination in E. medusa mitochondria. Despite the fact that the control region is assumed to have a lack of resolving power in other species, I found a considerable genetic variation of this marker in E. medusa which makes it a useful tool for phylogeographic studies. In combination with the allozyme data, the mitochondrial genome supports the following phylogeographic scenario for E. medusa in Europe: (i) a first vicariance, due to the onset of the Würm glaciation, led to the formation of several major lineages, and is mirrored in the NCPA by restricted gene flow, (ii) later on further vicariances led to the formation of two sub-lineages in the Western lineage and two sub-lineages in the Eastern lineage during the Last Glacial Maximum or Older Dryas; additionally the NCPA supports a restriction of gene flow with isolation by distance, (iii) finally, vicariance resulted in two secondary sub-lineages in the area of Germany and, maybe, to two other secondary sub-lineages in the Czech Republic. The last postglacial warming was accompanied by strong range expansions in most of the genetic lineages. The scenario expected for a presumably Siberian faunal element such as E. medusa is a continuous loss of genetic diversity during postglacial westward expansion. Hence, the pattern found in this thesis contradicts a typical Siberian origin of E. medusa. In contrast, it corroboratess the importance of multiple extra-Mediterranean refugia for European fauna as it was recently assumed for other continental species.

Luxurious Merovingian Textiles Excavated from Burials in the Saint Denis Basilica, France, 6th-7th century

A new examination of the textile fragments found in the Merovingian burials in the basilica of Saint Denis, near Paris, has recently underscored the diversity of fabrics used to make garments in which members of the royal court were buried. Among them, some woolens of fine quality had been dyed with indigotin. The most astonishing fibre found belongs to a mixed textile (not skin) with beaver fibers and wool. Silks contained shellfish purple and in one case kermes? Two dyestuffs associated with royalty and privilege. Along with this was large number of gold threads, probably produced locally and that were used in tablet-woven borders or for embroideries. In addition, several figured silks, of oriental origin, testify to the importance of this "foreign" material and the taste for textiles woven with complex techniques and probably what had originally had beautiful designs. Although none of these designs have been preserved and many colors have been greatly damaged, the technical characteristics of the remnants indicate proveniences as far as Byzantium, Sassanid Persia and the Chinese court. Such precious textiles show the high social status and political power of the Merovingian court, a testament to their ability to access such luxurious and costly textiles through diplomacy and/or trade with other powerful empires. The examination of these rare textiles along with other fine silks and luxury objects from the same period found in France expand our view of the fundamental role of textiles in the political sphere of this early period of European history.

Traducción de poesía: forma, repetición y fantasma en el estudio comparado de traducciones de Emily Dickinson (Silvina Ocampo, Amelia Rosselli)

Este trabajo se inscribe en el proyecto de fundación de una Escuela de Traducción Poética, en la que nos proponemos pensar y practicar nuevos criterios específicos para traducir poesía. Las premisas teóricas de Walter Benjamin y Giorgio Agamben nos sirven para pensar nuestra tarea como una Nueva Filología. Será fundamental en ella el estudio interdisciplinario en el que confluyen filosofía, historia, psicoanálisis, estética y teoría literaria. Una filología absorta en la facticidad y la devoción mágica por los particulares, por el detalle, que Agamben destaca como fundamentales en Benjamin.

La puñalada de Amelia (o cómo se extinguió la discriminación de las mujeres casadas del servicio telefónico en la Argentina)

Esta comunicación ilumina las huellas de Amelia C. Su historia de vida como telefonista es relevante para comprender la discriminación de las mujeres en el mercado laboral en los comienzos del siglo XX. Este artículo se enfocará en el estado conyugal como pauta de exclusión femenina. La estrategia utilizada por Amelia contra dicha pauta, si bien individual e incluso desesperada, detonó una serie de revisiones de la legislación existente que fueron apoyadas por distintos grupos de la sociedad. El corpus está basado en expedientes de la compañía telefónica en la que Amelia se desempeñó como empleada durante varios años y en el impacto que sus estrategias tuvieron en la prensa local.
