Climate change and marine heatwaves introduce strong, directional selection for heat tolerance which, in turn, alters the genetic composition and diversity of marine species. While this may facilitate adaptation to warmer conditions, reduced genetic diversity may limit resilience or cause maladaptation to additional stressors. This project will focus on habitat-forming kelps and will aim to both assess the negative consequences of rapid selection and to disentangle the mechanisms of climate adaptation. Through a powerful combination of controlled experiments on known genotypes and cutting-edge transcriptomic approaches, this project will transform our understanding of the adaptability of foundation species in a rapidly changing ocean.

气候变化和海洋热浪对耐热性产生了强烈的定向选择，这反过来又改变了海洋物种的遗传组成和多样性。虽然这可能有助于适应更温暖的条件，但遗传多样性的减少可能会限制恢复力或导致对额外压力源的不适应。该项目将重点关注形成栖息地的海带，旨在评估快速选择的负面影响，并理清气候适应的机制。通过对已知基因型的控制实验和尖端转录组学方法的有力结合，该项目将改变我们对基础物种在快速变化的海洋中的适应性的理解。
