: Response of plant populations to changes in the environment is at the core of climate change research. For decades invasion biologists have investigated the ecological and evolutionary responses of individuals and populations to novel environments. This organised oral session aims to highlight the potential for invasion biology to help answer questions about how and how fast we might expect populations to move, re-assemble and adapt to climate change. Several processes which will be important for predicting the response of plant populations to climate change have direct analogs in invasion ecology, including population spread to new areas, adaptation to novel conditions and assemblage of novel communities. This session provides an opportunity to explore the area between climate change research and invasion biology, and offer ideas for new research directions in both invasion and climate change ecology. Research across a broad range of topics in invasion ecology from spread, establishment, in situ adaptation and biotic interactions will be presented along with sociological aspects of the perception of invaders/climate change migrants and the interaction between population management and climate change. More specifically the session will address the questions of identifying species’ potential to adapt to new environments from comprehensive study of invasions (with the genus Acacia in South Africa - Prof. Richardson, and an invasive thistle - Rui Zhang); plasticity of invaders’ traits (Prof. Dr van Kleunen) and how novel environments can select for these traits (Dr Cheptou); how climate change can create novel soil-plant interactions (Dr Peltzer); how invasive species in various environments can give a picture of species’ responses to climate change (Dr Diez), and finally sociological aspects of invasions, and how they can affect public perception of novel plant dynamics (Dr Larson).
