英文摘要	As human activities have an increasingly detrimental effect on the natural environment it has become critically important to understand how habitats and species will cope with such rapid changes. The ability of a species to adapt is a crucial component of its resilience to climate change and this is reflected in recent attempts to include some component of adaptation in predictive models. However, we have a very poor understanding of the factors that might predict the evolvability of a species and so it is currently not possible to separate adaptive ability from plasticity, or broad niche breadth, based on the current environmental tolerances of a species. A first step in understanding whether evolution might be predictable in wild organisms is to understand the extent to which the adaptive process is repeatable and reproducible and what genomic signatures/features allow rapid adaptation to take place (making it identifiable). To bridge this knowledge gap we need to study instances of contemporary parallel adaptation (<200 years), such as the rapid adaptation of Silene uniflora to heavy-metal contaminated soils at abandoned mines. This project will use state-of-the-art genetic/genomic analyses, quantitative genetics and experimental evolution studies. It will investigate the roles of standing genetic variation in the adaptive process, reveal the key signatures of rapid parallel evolution and investigate the potential for strong natural selection to drive reproductive isolation of populations at very small scales (i.e., a few meters). In so doing, it will uncover the genetic and genomic patterns that will help us to recognise and estimate the potential of plant species to adapt to rapid and extreme environmental change. As genome-scale sequencing becomes more accessible, it will be possible to analyse and assess genetic variation quickly and easily in any species. Hidden in this wealth of genomic data are the clues to whether species will adapt or perish; the proposed project will help researchers to decode those clues.
