Acknowledgments
This research comes from a long process and no doubt collective work of many people. For that the highest award, I have to say to them who supervised and supported me until the completion of this thesis.
I would like to express my gratitude to my supervisor, Prof Dr. Michael Mühlenberg (Zentrum für Naturschutz) whose understanding, expertise and encouragement added to my graduate experience; Prof. Dr. John Keith Hodges (Deutsches Primatenzentrum) for his patience, critics and discussions for valuable result of this work.
I must acknowledge to Dr. Thomas Ziegler (Deutsches Primatenzentrum) and Dr.
Matthias Waltert (Zentrum für Naturschutz) who introduced me in the world of primatology, ecology and conservation in practice. Their support, motivation, patience, accompanied me during field work in Siberut and made the write of my thesis in Germany an unforgettable memory for me.
I would like to thank the field assistants Rahmah T. Rahayu, Dwi Retno Rahayuni, Dwi Y. Febriyanti, Ratna Wulandari, Yohanes Wibisono, Vera Ikawati, Yulia D. Handayani, Taswirul Afiyatin, Khusnul Khotimah, Wahyuni Mahmud, Puska Kamaliasari and Levi Madina for their support during data collection, as well as the local field guides: Sebulon, Mitcen, Hermato, Rizel, Viator and Lucian for their help during exploring the forest and following the monkeys.
Many thanks as well as to SCP (Siberut Conservation Project) management team lead by Dr. Mohammad Agil (Bogor Agricultural Insitute) with team member of Dodi Priata, Fauzan Syamzuri, Abdul Aziz, Siti Aminah, Edith Sabara, Feri Irawan, and Eko Priambodo, for administrative support, logistic and field support.
I thank the persons who helped to collect plants, especially Pak Benson, Pak
Tarianus, Pak Nauli and Pak Tarzan and the staff of the Herbarium Andalas University in Padang and Herbarium Bogoreinse in Bogor for identification of collected material.
I also grateful to Dr. Michael Heistermann, Dr. Antje Engelhardt, Jan-Boje Pfeifer, Dirk Meyer, Tanja Wolf, Rasmus Liedigk, Sabine Hutschenreuther, Julie Duboscq, Christof Neumann, Cedric Buttoz, Christine Richter, Marcel Quinten and Juan Fran Gallardo for their motivation and friendship that supported me in the struggle to finish this thesis.
Very special thanks go out to Ellen Wiese on her assistance in administrative support and her hospitality during my stay at the DPZ.
I recognize that this research would not have been possible without the financial assistance of the “Prince Albert II of Monaco Foundation” for partly funding, the “Idea Wild” foundation for providing items of fieldwork equipment and DIKTI-Gadjah Mada University for partial scholarship.
Finally I would like to thank my father and mother for their praying in particular;
giving me the air of motivation to finish this work and going back home soon. I dedicated this thesis especially to them.
