Juliana Chacón Pinilla München, 25. Juli 2013 v Note In this thesis, I present the results from my doctoral research, carried out in Munich from September 2009 to July 2013 under the guidance of Prof. Dr. Susanne S. Renner. My thesis resulted in five manuscripts, presented in Chapters 2 to 6, of which two have been published (Chapters 2 and 5), two are in review (Chapters 3 and 4), and one has been accepted pending minor revision (Chapter 6). I also gave the presentations listed below. I generated all data and conducted all analyses myself, except for the estimation of ancestral chromosome numbers in Colchicaceae (part of Chapter 6), which was done with help of Dr. Natalie Cusimano, and the identification of fossil leaves from New Zealand (Chapter 3), which was done in collaboration with Dr. John G. Conran (The University of Adelaide, Australia), Dr. Dallas C. Mildenhall (Institute of Geological and Nuclear Sciences, New Zealand), Dr. Jennifer M. Bannister, and Dr. Daphne E. Lee (University of Otago, New Zealand). Writing and discussion involved collaboration with Professor Susanne Renner. List of publications Peer-reviewed journal articles CHACÓN, JULIANA, M. C.
