This project aims to test whether rapid evolutionary responses can buffer marine species against the environmental changes impacting Australia’s coastal ecosystems now and in coming years. This project plans to use an innovative experimental evolution framework to test the newly-advanced theory of evolutionary rescue, its goal is to understand whether populations can adapt to new environments fast enough to outpace extinction, and how phenotypic plasticity, fluctuating natural selection and biotic interactions influence extinction risk. The intended outcome is to deliver key insights into the intrinsic capacity of our marine biota to withstand the current and near-future challenges that they face, and to inform predictions about population persistence. In doing so, this project should deliver vital information on extinction risk to managers, policy-makers and other stakeholders, and contribute innovative, cutting-edge research in an area of national priority.

该项目旨在测试快速进化反应是否可以缓冲海洋物种对环境变化的影响，澳大利亚的沿海生态系统现在和未来几年。该项目计划使用一个创新的实验进化框架来测试最新的进化拯救理论，其目标是了解种群是否能够快速适应新环境以超过灭绝，以及表型可塑性，波动的自然选择和生物相互作用如何影响灭绝风险。预期的结果是提供关键的见解，我们的海洋生物群的内在能力，以承受当前和不久的将来，他们面临的挑战，并告知人口持久性的预测。在此过程中，该项目应向管理人员、政策制定者和其他利益攸关方提供有关灭绝风险的重要信息，并在国家优先领域贡献创新的前沿研究。
