First and foremost, I want to express my particular thanks to some Chinese scientists and friends who helped me realize this book: Professor Liang Fei, the former director of the Department of Herpetological Research at the Chengdu Institute of Biology of the Chinese Academy of Sciences, and his wife, Professor Changyuan Ye, formerly also of the Chengdu Institute of Biology, who both worked on amphibians for many years. I would also like to express my deep gratitude to Emmanuel Jelsch and Jérôme Maran for their guidance, enthusiastic encouragement, and useful criticism; David Oudjani for his advice and assistance with keeping my progress on schedule. I thank the French Urodela Group (FUG) and the AG Urodela (DGHT/Germany), L'Association du Refuge des Tortues (A.R.T., France), and the Société Herpétologique de France (SHF) for their support. My gratitude furthermore extends to my good friend Mian Hou, who helps me with this project through his research in China and our moments together while working in the field. He is also co-author of the chapter on T. verrucosus. I would like to extend my thanks to the technicians at the Department of Biology at the University Pasquale Paoli in Corsica; the Chengdu Institute of Biology (Sichuan); the Kunming Institute of Biology; and the Zhejiang Natural History Museum (China); Cathy Gibault at Thoiry’s Zoological Park who gave me the opportunity to work with her team for a little while; and the Department of Zoology in Moscow and Nikolay Poyarkov for their availing resources required for running my project. I thank Shruti Sengupta to be co-author of the chapter on T. verrucosus and especially for the Himalayan region of India.
I thank also the Bleustein-Blanchet Foundation, especially Anne De La Baume, Béatrice Netter-Leval and Nathalie Royer, who helped me a lot with obtaining a grant for this study in Asia. I thank Elisabeth Badinter, Arthur Sadoun, Mohed Altrad, and Allain Bougrain-Dubourg for their giving me the opportunity to win a special prize as a laureate of the foundation in 2015. I also thank Edition Chimaira for their input and assistance with this book.
