M. Crowe Co-supervisor: Assoc. Prof. P. Bloomer 2005 ACKNOWLEDGEMENTS I would like to thank my supervisors Tim Crowe and Paulette Bloomer. Tim, thank you for the opportunity to work on this project as well as your patience and perseverance. Paulette, thanks for your friendly advice and help throughout the project, particularly in the draft stages. Thanks must also go out to all the wingshooters who provided samples of guineafowl from across Africa. To all the members of lab MEEP thank you for accepting me into the lab and making me feel welcome. In particular: Lisel Solms for getting me started in the lab, Carel Oosthuizen for sorting out the admin. in the lab and with the university, as well as being roomy for a while, Wayne Oelport for help with analysis and computer related issues, as well as a golf buddy. A mention must also go to Michael Cunningham for project advice and late night games of hallway footy, Marina Alais and Isa-Rita Russo for the drinks we shared of an evening. Town To my other Pretoria 'maatjies', Minique de Castro, Vinet Coetzee, Tracey-Leigh Hatherell and Jason Pienaar, thanks for some great evenings and weekends away that kept me sane during the project. Cape of Finally, I would like to thank my parents for putting me up and putting up with me for the duration of the thesis, and especially for monetary, culinary and hydratory support throughout. Thanks for your support and dogged patience in a marathon struggle that seemed an ultra most of the time. I really appreciate everything that you have done for me through the years.
