The project aims to test when, where and how exotic plant populations become invasive through the rapid evolution of chemical compounds that inhibit native plant species. Using an innovative quantitative genetics framework, the intended outcome is to determine how the chemicals are selected, and whether there is sufficient heritable variation for the chemicals to evolve across heterogeneous landscapes characteristic of introduced ranges. The project will deliver key insights into the ecological and genetic mechanisms of adaptive evolution in invasive species, and predict evolutionary dynamics of biological invasions that inform their effective management. The project’s expected outcomes will be useful to policy makers, weed managers and farming communities.

该项目旨在测试外来植物种群何时、何地以及如何通过抑制本地植物物种的化合物的快速进化而成为入侵物种。使用一个创新的数量遗传学框架，预期的结果是确定如何选择化学品，以及是否有足够的可遗传变异，使化学品能够在引进范围的不同景观中进化。该项目将提供对入侵物种适应性进化的生态和遗传机制的关键见解，并预测生物入侵的进化动力学，为其有效管理提供信息。该项目的预期结果将对政策制定者、杂草管理者和农业社区有用。
