This project aims to unravel where and when marine heatwaves drive loss of genetic diversity and rapid directional selection in kelp forests. Although the devastating ecological impacts of marine heatwaves are well studied, empirical understanding of how marine heatwaves impact underlying evolutionary processes including adaptive capacity and resilience is lacking. This research will use a powerful combination of innovative heatwave analyses, cutting-edge genomics and physiological experiments to fill these knowledge gaps and represents a step change in our understanding of how kelp respond and adapt in multi-stressor seascapes. Results will pave the way for development of novel mitigation strategies to future-proof marine management.

该项目的目的是在海带森林中的遗传多样性和快速定向选择的何时揭示何时和何时何时何时何时进行遗传多样性的丧失。尽管对海洋热浪的毁灭性生态影响进行了充分的研究，但对海洋热浪如何影响包括适应能力和韧性在内的进化过程的经验理解。这项研究将使用创新的热波分析，尖端的基因组学和生理实验的强大组合来填补这些知识差距，并代表了我们对海带如何响应和适应多压力海景的理解的一步变化。结果将为开发新型缓解策略的发展铺平道路，以实现未来的海洋管理。
