Reading* and Examination Committee Prof. Anthony Herrel (MNHN, Paris + WE11)* Dr. Danny Meirte (Africa Museum, Belgium)* Dr. Zoltan Nagy (KBIN, Belgium)* Prof. Luc Lens (Ghent University, Belgium) Prof. Dominique Adriaens (Ghent University, Belgium) Prof. Frank Pasmans (Ghent University, Belgium) Dr. Tom Geerinckx (Ghent University, Belgium) I dedicate my dissertation to Dr. Mahmoud Latifi his great book, snakes of Iran, inspired me to study about biodiversity of the snakes in Iran Acknowledgement The success and final result of this thesis required a lot of guidance and assistance from many people and I am extremely fortunate to have got this all along the completion of my research course. Whatever I have done is only due to such guidance and assistance and I would not forget to thank them. I take this opportunity to express my profound gratitude and deep regards to my promoter Prof. Dr. Dominique Adriaens, for his exemplary guidance, supports and constant encouragement throughout the course of this thesis. Without him and his kind supports I could never accomplished this thesis. His great guidance, statistical comments, very detailed scientific discussions and patience to read and correct my drafts enabled me to complete my PhD dissertation. One simply could not wish for a better or friendlier supervisor. Thank you my dear professor. I am obliged to the research staff of the International Center for Science, High Technology and Environmental Science (ICST). Most of this research were supported by ICST research grants. I am very thankful to the president of ICST, Prof. Dr. MJ. Khanjani and official managers, Dr. Naseri, Dr. Alizadeh, Dr. Yaghubi, Dr. Bordbar and Dr. Kalantary. My sincere thanks go to all the personnel of ICST specially my friend and colleague, A. Yazdanpanah. I am grateful for their cooperation during the period of my assignment. I owe sincere and earnest thankfulness to my scientific colleagues, Prof. Dr. Nasrullah Rastegar-Pouyani, prof. Dr. Hamid Reza Esmaeili, Prof. Dr. Göran Nilson, Josef Schmidtler, Dr. Nikolai Orlov, Prof. Dr. Natalia Ananjeva, Dr. Nikolaus Stümpel, Prof. Dr. Ulrich Joger, Dr. Bahram Kiabi, Dr. Majid Kaboli, Dr. Haji Gholi Kami and Dr. Daniel Melnikov. I am also deeply indebted to my colleagues and friends in the field expeditions, specially my dearest friends Dr. Hiva Faizi and Dr. Roman Nazarov and my colleagues, Fariborz Heidary, Amin Ghadami, Soheila Javanmardi, Ruzbeh Behruz, Masoud Yousefi, Bahman Zangi and Mohammad Jahan. My sincere thanks go to my colleagues in the Evolutionary Morphology of Vertebrates research group, especially Tom Geerinckx, Barbara De Kegel, Joachim Christiaens and Hilde Van Wynsberge for their kind cooperation. I am profoundly indebted to the members of my PhD jury: Prof. Dr. Anthony Herrel, Dr. Danny Meirte, Dr. Zoltan Nagy, Prof. Dr. Luc Lens, Prof. Dr. Frank Pasmans and Dr. Tom Geerinckx. I gratefully acknowledge the kind cooperation of the following scientists for loan of the specimens or providing valuable data about specimens out of Iran: Michael Franzenand and Frank Glawin in ZSM, Patrick Campbell and Barry Clarke in BMNH, Roman Nazarov and Valentina Orlova in ZMMU, Raffaeil Ernst in MTKD, Aziz Avci in Adnan Menderes Üniversitesi, Boris Tuniyev in Sochi National Park Scientific Department and Konstantin Milito in ZISP. Last but not the least, I would like to appreciate my family for their unending support, encouragement and prayers. Really words fail me to express my deepest appreciation to my Mother. I am grateful to my Financee, Jaleh, and thanks to her family for supporting me. Through preparing this thesis, Jaleh was always beside me and motivated me all the time. Finally, I would like to thank everybody who was important to the successful realization of this thesis, as well as expressing my apology that I could not mention them personally one by one.
