^**Samantha E Jones has a BA joint honours degree in Geography and German from the University of Plymouth, England, an MSc in Environmental Archaeology from Queen's University, Belfast in Northern Ireland and a Phd, in Quaternary palynology from the Kelabit Highlands of Sarawak, Malaysian Borneo. The Phd was also based at Queen's University. Her PhD research has produced a 50,000 year record of vegetation change with evidence of fluvial and climate change, disturbance from 6000 cal BP and palm cultivation/arboreal practices from 3000 cal BP. Her main interests include vegetation response to environmental, cultural and climatic change; prehistoric transitions (from hunter gathering to farming/arboreal practices); and the identification of both modern-fossil pollen as well as other palaeoecological indicators. She is currently based at the Institute of Catala de Paleoecologia Humana i Evolucio Social (IPHES), in Tarragona, Spain on a Marie-Curie IFF fellowship. Her current project aims to use multi-proxy analysis (including pollen) to examine the effects of abrupt climatic events on prehistoric societies from the Iberian Peninsular.
