To Lucia and Paolo, my guardian Angels. i ACKNOWLEDGEMENTS This work started in 1995 and has encompassed fundamental years of my life. Honestly, it would be difficult not to forget someone that helped, in some way or another, in this long and complex delivery. Many people crossed my life and helped substantially, sometimes with a providential smile or other times with many years of working and walking together. I would feel very bad finding out a minute after having bounded this thesis that I have mentioned most but forgotten someone… So I decided to ‘forget’ all names, acknowledging people in a different way. I really hope this ‘different way’ will work and you will all recognise your precious contribution in the following lines… To my family, the original one and all its ‘extensions’, for the faith, colours, love, affection, dignity, music, words, strength, virtues, examples, tolerance, openness, will, endurance, joy and all the other “things” that I have been able to breath, absorb and ‘amplify’ with you. Thanks for the moral and material support but, above all, for your patience and for the freedom you gave me, which were the real opportunities that I was given. Thanks also to all those members of my family (relatives and friends) supporting me from ‘above’, taking care of me from a different dimension. At least, five years of thanksgivings to my supervisor for guiding me scientifically throughout this long and troubled path. All the good things you will find in this work certainly come from him; all the others are likely my contribution. Thanks for being an example of unremitting patience, absolute honesty and dedication, genuine and acute scientific insight. Thanks for greatly improving my scarce and poor scientific tools and for teaching me a method to follow in the years to come. Thank you for make me understand that also free-time is a fundamental part of the whole…. and that “virtus in medium stat”. A special thank to his family, particularly to his wife for welcoming me any time it was needed, despite the convenience of the situation. A special acknowledgement goes to those that started the Adriatic Dolphin Project (ADP), unaware of the sparkle that catalysed my career. But, above all, I’m thankful to the past and present “multiethnic Lošinj team” (Lošinjian, German, Croatian, Italian, British, Slovenian, Greek, Austrian eager people), which kept the project alive and well going through a highly critical historical and political period. Thanks for your unwavering and unreserved support. Thanks for being there. Thanks for believing in a dream that sometimes, especially at the beginning of this study, it was more mine than yours. In particular… ... a rain of thankful smiles to my English best friend, for being at the right time in the right place, when the ADP most needed it; for being there whenever I need it, during the good and the bad days; for being sometimes very British and amazingly Mediterranean in other occasions; … in few words, for his true, sharp, and fair friendship. Many thanks also for his constructive inputs to this work and for being deadly bored reading the draft of this thesis. … a storm of grateful hugs goes to my best Croatian friend for his “toll-free” friendship, dry humour and help in gathering rarely accessible information required for this work; ii for making me feel like a sister (actually knowing the way he treats his sister, I should say, more than a sister); for being always frank and for all disgusting jokes that only he can appreciate but that often, because of their craziness, made my days. … a lightning bolt of kisses to my best German friend for her constant support and encouragement, for carrying the mantle of the ADP moving us all along the way. Thanks to her Polish blood that made me feel comfortable at her Teutonic presence; thanks for sharing with me interminable hours at the light-table. Thanks to all paying volunteers that supported the ADP: without you nothing of this could have happened. Thanks to all sponsors, institutional and private that believed in us. Thanks to the “Greek Classical Beauty” for all laughs, serious talks and colourful dreams; for being a source of inspiration (can you believe it?!) and for all work we will finally manage to do together! What to say to my Spanish best friend? Too many words could ruin the sentiment ☺ … so accept only three of them from my side: gratitude, love and respect … for everything… for ever. Thanks to my best Irish friend for many good reasons, the most important being his capacity to keep his smile, fairness and resourcefulness when all around seems rather meaningless. Thank you, another good example to follow. To my two “V.I.P.” friends, the only two I know and that (seriously) I wish to known; thanks for believing in me, for respecting me professionally and personally, and allowing me to keep dreaming on the future. Particularly, a grateful thought to the Italian VIP that in a disillusion period on the system and society, showed me that, despite a generalised bad habit affecting the world, there are still people at a high level, holding a strong and genuine institutional awareness, working towards a collective interest. Thanks because that was a fundamental message that helped preserving my ideals. Thanks to all people that generously helped me during the five years of studies in St. Andrews. Particularly… … to all SMRU staff, whose example has been and will be a model for my present and future carrier. … to my favourite IT help, indubitably “user-friendly”, for solving all my technical problems when learning how to use new (to me) software and easing my life when needed; for taking care of me at the very beginning; for being a good and genuine friend all the way through. … to my (probably unaware) Scottish best friend for her solar smiling face; for helping me to find solutions to my computational and analytical problems at the beginning of my PhD; for proof-reading some of these chapters at the end of my PhD and especially for welcoming me to her house in the most critical time of this adventure (thanks to her Welsh partner too!☺) To my dozens of old good friends from Florence, Rome, Venice, Gradisca, Mazara del Vallo, Poiters, Bergamo that have been forgotten in the fog of my last five busy years… thanks because any time, thinking of you, I felt very lucky; thanks for all dreams I have been dreaming with you, some of which are now reality … thanks for your patience, iii respect and tireless love. Sorry for having totally or almost totally interrupted any kind of communication…. unfortunately, communication becomes impossible when one struggles to communicate to herself… now this seems to be sorted out and I promise I’ll do my best to be a good friend. Thanks to all Kvarnerić bottlenose dolphins for bearing and surviving to this long-term wildlife paparazzi project… sorry … and I truly hope that something small but good and practical for your conservation will follow from this work. Huge thanks to my Precious Treasure with the only promise that, as apprentice conservation biologist, with your permission, I’ll do my best to “conserve” you in my life ☺. Thanks to my future Love with my aware engagement to do my best for improving myself, promising you that “if thou hast me, at the worst; and thou shalt wear me, if thou wear me, better and better”. I would also like to thank the person that unaware inspired me and made me cross the “marine route” when I was still at the high-school. Because dreaming on his biography and his articles published on a popular Italian magazine (“Aqua”), I dreamt my future and spurred myself to make it possible. At last, but certainly not least, thanks to God that grasped me in several occasions as a father that loves his children as they are. Thanks for duly putting on my path what I needed, people, faces, situations, good or bad ones, which always brought me back to You inside me and outside me. I’m deeply grateful to all “firemen” that surrounded me during my long apprenticeship, showing me the noble art of extinguishing every kind of fire. Without them, nothing that was properly done during my past 37 years could have ever been possible. I truly hope they will continue believing and teaching to the others that “the goal never justifies the means” and that “violence” (in any of its subtle forms) can only generate “violence”, no matter what your field of expertise is. …thanks again to all… for all… iv DECLARATIONS I, Caterina Maria Fortuna, hereby certify that this thesis, which is approximately 48,000 words in length, has been written by me, that it is the record of work carried out by me and that it has not been submitted in any previous application for a higher degree.
