This project aims at investigating plant dynamics and forest development in the past (the last 130 000 years) and using this information to assist scientists modelling geographical range shifts in response to future climate changes. Range limits of many plant species are expected to shift considerably in the next decades due to human-mediated climate change, particularly in Nordic environments, but the capacity of trees to migrate in response to these events has been questioned.I propose to look directly in the species DNA retrieved from fossil plant archives (peat and lake sediments), investigate how species and lineages responded in the past and derive lineage specific tolerances and migrations rates for trees in northern Europe. I propose a multidisciplinary and highly focused study on fossil plant material - pollen and macrofossils - and ancient DNA extracted from fossil archives of northern Europe, based on classical palaeoecological investigations, front-line molecular techniques (metabarcoding and next-generation sequencing analyses) and ecoinformatic modelling analyses (ecological niche models).The outcome from this project will (i) assist ecological niche-modelling analyses of future range shifts, (ii) help scientists investigating the driving factors affecting range shifts (i.e. climate and dispersal constraints), and (iii) be directly usable by forest managers interested in identifying provenances with traits related to tolerance to changing climates.
