Marine heatwaves drive loss of genetic diversity and selection in kelps

该项目旨在揭示海洋热浪在何时何地导致海藻森林遗传多样性的丧失和快速定向选择。尽管海洋热浪的破坏性生态影响已经得到了很好的研究，但对海洋热浪如何影响潜在的进化过程，包括适应能力和复原力，缺乏经验上的了解。这项研究将利用创新的热浪分析、尖端基因组学和生理实验的强大组合来填补这些知识空白，并代表着我们对海带如何应对和适应多种应激源海景的理解发生了一步变化。结果将为制定新的缓解战略，以应对未来的海洋管理铺平道路。

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.
