Do species move, adapt or die? Exploring past biodiversity, ecological change and community dynamics in the fossil record – The remains of many species are well-preserved in Quaternary palaeoecological deposits and offer the opportunity to explore the formation, development and dynamics of biological communities over long temporal periods and address a range of key ecological and conservation questions. In this session, we particularly encourage papers that seek to explore species and community spatio-temporal dynamics and interactions, spread, extinction and niche evolution, over the different time-scales that apply to Quaternary studies. The session is convened by Nicki Whitehouse (Plymouth Uni.) with Helen Roe, Donatella Magri, Jane Bunting & me. Full details at http://www.pages-osm.org/osm/sessions-osm (session no. 19).
