An easy-to-navigate pocket guide to the Meeting is also available to delegates. Venue The Annual Meeting will take place in the faculties of Philosophy and Philology on the Blasco Ibañez Campus of the University of Valencia. The Symposium will take place in the Salon Actos Manuel Sanchis Guarner in the Faculty of Philology. The main meeting will take place in this and a nearby lecture theatre (Salon Actos, Faculty of Philosophy). There is a Metro stop just a few metres from the campus that connects with the centre of the city in 5-10 minutes (Line 3-Facultats). Alternatively, the campus is a 20-25 minute walk from the ‘old town’. Registration Registration will be possible before and during the Symposium at the entrance to the Salon Actos in the Faculty of Philosophy. During the main meeting the registration desk will continue to be available in the Faculty of Philosophy. Oral Presentations All speakers (apart from the symposium speakers) have been allocated 15 minutes. It is therefore expected that you prepare to speak for no more than 12 minutes to allow time for questions and switching between presenters. We have a number of parallel sessions in nearby lecture theatres so timing will be especially important.

    INSIGHT REVIEW NATURE|Vol 457|12 February 2009|doi:10.1038/nature07890 The origin and evolution of arthropods Graham E. Budd1 & Maximilian J. Telford2 The past two decades have witnessed profound changes in our understanding of the evolution of arthropods. Many of these insights derive from the adoption of molecular methods by systematists and developmental biologists, prompting a radical reordering of the relationships among extant arthropod classes and their closest non-arthropod relatives, and shedding light on the developmental basis for the origins of key characteristics. A complementary source of data is the discovery of fossils from several spectacular Cambrian faunas. These fossils form well-characterized groupings, making the broad pattern of Cambrian arthropod systematics increasingly consensual. The arthropods are one of the most familiar and ubiquitous of all ani- Arthropods are monophyletic mal groups.

A THESIS IN GEOSCIENCE Submitted to the Graduate Faculty of Texas Tech University in Partial Fulfillment of the Requirements for the Degree of MASTER OF SCIENCE Approved Chairp^son of the Committee Accepted Dean of the Graduate School December, 2001 ACKNOWLEDGEMENTS I would like to express my appreciation to Dr. George B. Asquith for his constant guidance, assistance, and encouragement during my tenure at Tech. He has been a second father to me and a great teacher; his influence has truly shaped my life. I am also grateful to my graduate committee, Dr. Tom Lehman and Dr. Moira Ridley, for their assistance and review of my thesis. I would like to thank R.T. Winn, Jason Slayden, Cindy Welch, and Lee Wood (my father) for their assistance in the field. Thank you to the Young family for allowing me access and the opportunity to work on their beautiful ranch. I would also like to thank Mike Gower for his help in preparing thin sections, and his assistance with any other questions I had. His help was greatly appreciated. Thank you to Dr. Mark Crimson for his assistance in the SEM lab and to the Department of Biological Sciences at Texas Tech University for providing access to the Electron Microscopy Laboratory. I would like to dedicate this thesis to my parents and grandparents, the people that have influenced my life the most. I am glad they all stayed around long enough to see this.
