Genetic variability and differentiation in the Mediterranean endemic starry ray Raja asterias (Delaroche, 1809)

The present study deal with the population structure and connectivity of the Mediterranean endemic starry ray Raja asterias (Delaroche, 1809) in the Western and Eastern Mediterranean basin. A panel of eight microsatellite loci which cross-amplify in Rajidae (El Nagar, 2010) was used to assess population connectivity and structure. Those aims were investigated by analyzing the genetic variation of 9 population sample for a total of 185 individuals collected during past scientific surveys (MEDITS, GRUND), commercial trawling and also directly at fish markets. The purpose of this thesis is to estimate the genetic divergence occurring between the Mediterranean populations and, in particular, to assess the presence of any barrier (geographic, hydrogeological and biological) to gene flow for this species. Different statistical approaches were performed to reach this aim evaluating both the genetic diversity (nucleotide diversity, allelic richness, observed and expected heterozygosity and Hardy-Weinberg equilibrium test) and the population differentiation patterns (pairwise Fst estimated and population structure analysis). The results obtained from the analysis of the microsatellite dataset suggest a geographic and genetic separation between the starry ray populations of the Mediterranean basin into three or four distinct groups: Western and Eastern Mediterranean basins and Sicilian coast always clustering as an independent group and Algeria which could be or not considered another separate group. The data were discussed from both an evolutionary and a conservation point of view and in relation to previous results obtained by the analysis of mitochondrial marker. A comparison with other Mediterranean demersal skate species was performed in order to better contextualise our results. Finally, our results could offer useful information to protect vulnerable species as R. asterias and developing effective conservation plans in the Mediterranean.

Proposta di traduzione in italiano commentata del racconto “O Verdadeiro Pecado de Xoán Zalzívar” della scrittrice portoghese Leonor Xavier

Lo scopo di questo elaborato è di presentare una proposta di traduzione verso l’italiano del racconto O Verdadeiro Pecado de Xoán Zalzívar della scrittrice portoghese Leonor Xavier, pubblicato all’interno della raccolta Picante – Histórias que ardem na boca. Dopo aver presentato brevemente la biografia e la bibliografia dell’autrice, ci si è soffermati sulla raccolta e sul racconto stesso. In particolare, sono state presentate le tematiche narrate e il filo conduttore della raccolta e successivamente è stata illustrata la trama del racconto. Al centro di questo elaborato vi è la traduzione e la rispettiva analisi. Infatti, è stata rivolta una particolare attenzione alle difficoltà nella resa in italiano, come la ricetta e i suoi ingredienti, le espressioni idiomatiche presenti nel testo di partenza, l’uso delle formule di cortesia e le scelte stilistiche della scrittrice.

Analyse du sous-titrage du film de Xavier Dolan "Les Amours Imaginaires": du français québécois au français "standard".

Ce mémoire est un travail d'analyse du sous-titrage du film de Xavier Dolan "Les Amours Imaginaires". Ce sous-titrage a été réalisé par CMC Video afin de traduire le scénario original du film –qui est en français québécois– en français standard pour la distribution du film en France. Dans la partie introductive du mémoire nous décrivons les caractéristiques de la variété de français parlée au Québec et nous introduisons le film et le cinéaste. Ensuite la partie centrale est une analyse lexicale, morphologique et syntaxique du sous-titrage que nous avons effectuée à l'aide de différents exemples tirés de la transcription parallèle du scénario et des sous-titres correspondants. Nous considérons ce mémoire comme un point de départ du long parcours d'un recherche qui viserait à donner des justifications à la raison pour laquelle les films et les émissions télévisées québécoises sont presque systématiquement doublées ou sous-titrées en France.
