Program and Abstracts for the 8 th International Conference on Marine Bioinvasions (20-22 August 2013, Vancouver, Canada) Cover photography & design: Kimberley Seaward, NIWA Layout: Kimberley Seaward & Graeme Inglis, NIWA 8th International Conference on Marine Bioinvasions Vancouver 2013 8th International Conference on Marine Bioinvasions Dear Conference Participant On behalf of the Scientific Steering Committee (SSC) and our sponsors, we would like to welcome you to Vancouver for the 8th International Conference on Marine Bioinvasions. Vancouver is a culturally diverse metropolitan city serving as the western gateway to Canada. We hope you will spend some time to explore all this city has to offer. We are grateful for all of the efforts of the SSC and the local organizing committee as well as for the generous support of our sponsors: the Biodiversity Research Centre at the University of British Columbia for hosting the event; the Canadian Aquatic Invasive Species Network (CAISN), for providing additional funding by sponsoring one of the plenary presentations; The North Pacific Marine Science Organization (PICES), for providing travel awards to early career scientists; and the National Oceanographic and Atmospheric Administration (NOAA), for donating additional funds. Above all else, we are grateful for your participation and willingness to discuss your ideas, latest research results, and vision. Among the papers, posters, and plenary presentations that comprise the conference, we hope you will find many opportunities for discussion and new collaborations. Finally, we hope this summation of the state of the field will provide solutions to the problem of marine invasive species as well as generate new research directions. Once again, welcome to the 8th International Conference on Marine Bioinvasions, and we look forward to a thought-provoking and rewarding experience!
