I am sincerely grateful for Yvonne’s knowledge, patience and encouragement throughout the entire PhD process. Thanks to Prof Myron Zalucki, a co-supervisor and wealth of knowledge. Myron was very generous with his time and always made me think outside the square. Thanks also to my other co-supervisor Dr Adele Reid. Adele always listened to my issues with empathy and managed to comment and edit my work thoroughly whilst caring for a new baby. Thanks to all of the people who took the time to assist me with field work. My data collection would have been impossible without the company and assistance of these wonderful volunteers. Thanks to David Perović and my sister-in-law Sarah Chilton, for always dropping everything to help out for days on end, Niels Hintzen and James Hereward for accompanying me on the long survey trips, Rebecca Roach for assisting in seed germination experiments and everyone else who helped out for days here and there including: Blair Chilton, Jennifer Firn, Adam Dinsdale, Satu Ramula, Megan Ward and Thomas Honegger. Thanks also to everyone in the Buckley lab, Spatial Ecology Lab, the School of Biological Sciences and at the Alan Fletcher Research Station. I am very grateful for your friendship, assistance and advice over the past few years. I wish to acknowledge the source of funding for my PhD research and conference travel: CRC for Australian Weed Management. The CRC was a fantastic organisation that provided a vast amount of support for its students and will be missed. Melinda McNaught (BSc(Hons) Zoology, PhD) kindly edited this thesis as a whole in accordance with Standard E (Completeness and Consistency) of the Australian Standards for Editing Practice. I am indebted to all of my friends who have supported me, in particular, Jennifer Firn and Céline Clech-Goods: for your consistent support, hot chocolates and motivation to keep going. Thank you also for all of your proof-reading and editing, it really did make a difference. Thanks to my immediate and extended families, in particular, Mum, Dad and Ashley as well as my in- laws, the Chilton clan for always believing in me and supporting me both morally and financially. Your 6 ongoing support brought me to this point and I am sincerely grateful. I also appreciate the vast number of difficult conversations you endured when you tried to explain what it is I actually did for 4 years. A huge thank you to my best friend and husband Blair for everything; his endless friendship, support, love and patience got me through the PhD process.
