In my group we study the ecology and evolution of forest plant populations: how genetics, demography and ranges of plants have changed during the climatic events of the last thousands of years. Over the past plants have persisted through long periods of climate change including several glacial and interglacial periods. Pollen and macrofossil records from lake and peat archives show how plant populations changed their ranges in response to changing climates and how few tolerant species may have survived at high latitudes during glaciations. Plant populations have also changed population sizes and genetic composition due to drift and adaptation to new environments. In our group we use modern DNA from living individuals and ancient DNA from pollen, macrofossils and sediments from lakes to investigate all these changes.
