My 4 main supervisor José Carlos Brito that gave me the possibility to work on this stimulating 5 thesis and helped me until the end of it. My co-supervisors Guillermo Velo-Antón that 6 helped me during the lab work and the genetic analysis. Pierre-André Crochet and 7 Philippe Geniez for the warm hospitality at the CERN in Montpellier and for their 8 availability in transmitting me useful knowledges. Antigoni Kaliontzopoulou and Fernando 9 Martínez-Freiría that introduced me to CIBIO and to the University of Porto and without 10 whom I wouldn’t never come to Portugal. Andres Pagan, Inês Dinis de Freitas, Silvia 11 Chemello, Orlando Gallo that helped me when I was lost and together with my flatmates 12 Luca, Clara, Aina and Fulvio supported me during this journey. 13 I would also love to thank my parents, my sister Maddalena, my uncle and aunt Giuseppe 14 and Cecilia, my friends Alberto, Dario, Francesco and Roberto for the love and support 15 they gave me that always made me feel home. Thank you. 16 This work was funded by National Geographic Society (CRE 7629-04/8412-08), Mohamed 17 bin Zayed Species Conservation Fund (11052709, 11052707, 11052499), Fundacão para 18 a Ciência e a Tecnologia (PTDC/BIA-BEC/099934/2008 and PTDC/ BIA-BIC/2903/2012), 19 FEDER funds through the Operational Programme for Competitiveness Factors - 20 COMPETE (FCOMP-01- 0124-FEDER-008917/028276), and by AGRIGEN–NORTE-01- 21 0145-FEDER-000007, supported by Norte Portugal Regional Operational Programme 22 (NORTE2020), under the PORTUGAL 2020 Partnership Agreement, through the 23 European Regional Development Fund (ERDF).
