“The Landscape of wheat - A landscape of power” pp: 66-70

Portugal in the end of the 19 th century was characterized by a huge economic and political instability. This situation led to the publication of the Hunger Law (1899), which is identified as the critical breaking point since it imposed a political ideology over a vernacular landscape. The Alentejo (south of Portugal), between (1889-1929) emerges as a paradigmatic landscapes where an abrupt transformation take place: an ancient landscape with the loss of their ecological memory was lost and a false identities was created. The diversity and ecological richness of the vernacular landscape gave way to the monotony of the cereal and the ecological and social system that for centuries had built up and evolved was abruptly compromised. To analyze and understand the important transformation that happened in the ancestral countryside of Alentejo, the research was based on the concept of landscape as a system, and that the landscape represents the relationship between the natural system and the cultural.

"Ancestry, gender and language - The role of culture in economic development"

This thesis is a combination of research questions in development economics and economics of culture, with an emphasis on the role of ancestry, gender and language policies in shaping inequality of opportunities and socio-economic outcomes across different segments of a society. The first chapter shows both theoretically and empirically that heterogeneity in risk attitudes can be traced to the ethnic origins and ancestral way of living. In particular, I construct a measure of historical nomadism at the ethnicity level and link it to contemporary individual-level data on various proxies of risk attitudes. I exploit exogenous variation in biodiversity to build a novel instrument for nomadism: distance to domestication points. I find that descendants of ethnic groups that historically practiced nomadism (i) are more willing to take risks, (ii) value security less, and (iii) have riskier health behavior. The second chapter evaluates the nature of a trade-off between the advantages of female labor participation and the positive effects of female education. This work exploits a triple difference identification strategy relying on exogenous spike in cotton price and spatial variation in suitability for cotton, and split sample analyses based on the exogenous allocation of land contracts. Results show that gender differences in parental investments in patriarchal societies can be reinforced by the type of agricultural activity, while positive economic shocks may further exacerbate this bias, additionally crowding out higher possibilities to invest in female education. The third chapter brings novel evidence of the role of the language policy in building national sentiments, affecting educational and occupational choices. Here I focus on the case of Uzbekistan and estimate the effects of exposure to the Latin alphabet on informational literacy, education and career choices. I show that alphabet change affects people's informational literacy and the formation of certain educational and labour market trends.

Protostrongylids nematodes as a tool to study the biogeography of wild mammals

The European brown hare (Lepus europaeus Pallas, 1778) is an important game species, distributed across Europe and introduced in other regions. Recently, a geographically isolated population, closely related to an ancestral lineage of Lepus europaeus meridiei, was found on Pianosa Island, off the coast of Tuscany, Italy (Mengoni et al., 2018). Thus, the unique opportunity to explore the evolution and genetic structure of its helminth parasites was added to its exceptional isolation condition. Various lungworm species within the genus Protostrongylus (Nematoda: Protostrongylidae) are described in European brown hares. Our aim was to analyze the parasite population through morphological and molecular approaches in order to study the biogeography of the European brown hares (L. e. meridiei) population from Pianosa Island. Moreover, we investigated the morphology of a monospecific genus, i.e. Orthostrongylus, considering its quite intrigant descriptive history and its still unclear and debated classification. Nuclear and mitochondrial markers were used based on their resolution power and expected polymorphism; the whole Internal Transcribed Spacer 1 and 2 (ITS), including the 5.8S rRNA sequence and the Large Subunit (28S) were used, as nuclear genes, for confirmation of the species identification. Conversely, the cytochrome oxidase c subunit I (COI) was used, as mithocondrial genes, to assess interspecific genetic relationships. Molecular analysis corroborated the morphological identification since all the generated ITS and LSU sequences were 100% consistent with the species Protostrongylus oryctolagi and Orthostrongylus macrotis. The paucity of molecular data existent about this genus of parasites underlines the need for more insight’s studies. An in-depth analysis of broncho-pulmonary parasites and the host-parasites relationships along with the improvement of the use of mitochondrial genes, as well as the assessment of new polymorphic markers could contribute to an extensive understanding of parasites fauna and taxonomy, as well as their relationship with wild mammals’ hosts.

Applied genomics in livestock: genome-wide association studies and population genomics analysis in pig and rabbit breeds

The domestication and selection processes in pigs and rabbits have resulted in the constitution of multiple breeds with broad phenotypic diversity. Population genomics analysis and Genome-wide association study analysis can be utilized to gain insights into the ancestral origins, genetic diversity, and the presence of lethal mutations across these diverse breeds. In this thesis, we analysed the dataset obtained from three Italian Pig breeds to detect deleterious alleles. We screened the dataset for genetic markers showing homozygous deficiency using two approaches single marker and haplotype-based approach. Moreover, Genome-wide association study analyses were performed to detect genetic markers associated with pigs' reproductive traits. In rabbits, we investigated the application of SNP bead chip for detection signatures of selection in rabbits using different methods. This analysis was implemented for the first time in different fancy and meet rabbit breeds. Multiple approaches were utilized for the detection of the selection of signatures including Fst analysis, ROH analysis, PCAdapt analysis, and haplotype-based analysis. The analysis in pigs was able to identify five putative deleterious SNPs and nine putative deleterious haplotypes in the analysed Italian Pig breeds. The genomic regions of the detected putative deleterious genomic markers harboring loss of function variants such as the Frameshift variant, start lost, and splice donor variant. Those variants are close to important candidate genes such as IGF2BP1, ADGRL4, and HGF. In rabbits, multiple genomic regions were detected to be under selection of signature. These genomic regions harbor candidate genes associated with coat color phenotype (MC1R, TYR, and ASIP), hair structure (LIPH), and body size (HMGA2 and COL2A1). The described results in rabbits and pigs could be used to improve breeding programs by excluding the deleterious genetic markers carriers and incorporating candidate genes for coat color, body size, and meat production in rabbit breeding programs to enhance desired traits
