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.

Analisi e traduzione di "The family law" di Benjamin Law

The aim of this dissertation is to propose a translation from English into Italian of The Family Law, an autobiographical novel written by Benjamin Law, an Australian author of Cantonese origins. The present dissertation is divided into four chapters. The first chapter presents the author of the book, by providing his biography; in addition, the chapter contains an overview of the Australia immigration problem, which is an important issue in the book due to the fact that the author’s parents had moved from Hong Kong to Caloundra, Australia. The second chapter presents the book The Family Law, by focusing on its main themes and by paying special attention to the description of the characters; furthermore, it analyses the plot of the chapters which I decided to translate, and provides a selection of Italian publishers which might be interested in publishing the book. The third chapter consists of my translation of the chapters I selected. The final chapter analyses the strategies I adopted while translating and examines some of the problematic issues that I encountered during the translation process, in particular at the level of morphosyntax, lexicon, cultural references, and style.
