Although evolution has been neglected in invasive species work, evolutionary theory can be used to guide invasive species management, and research on exotic species can be used to test evolutionary theory. One substantial challenge in invasive plant management is the evolution of resistance to herbicides, biological control, and other treatments. We show how the tools of quantitative genetics and selection analysis can be used to investigate the potential for evolution of resistance, which can aid in the management of invasive plant populations. We also illustrate how invasive species research can be used to test theory, such as the evolution of increased competitive ability hypothesis. We outline the methods to investigate this theory and recommend including evolutionary considerations in invasive species management.
