Abstract

Standing genetic variation in fitness-related traits is critical to determine how fast populations can adapt to climate warming but is unknown for many species. Here we show that heritable genetic variation in heat tolerance in reef-building coral populations is widespread and strongly associated with selective pressure imposed by marine heatwaves. Our findings suggest that coral populations may be adapting to warming consistent with recent increases in their upper thermal limits.

海洋热浪选择了造礁珊瑚的耐热性

健康相关性状的遗传变异对于决定种群适应气候变暖的速度至关重要，但对于许多物种来说，这是未知的。在这里，我们表明，在造礁珊瑚种群中，耐热性的遗传变异是普遍存在的，并且与海洋热浪施加的选择压力密切相关。我们的研究结果表明，珊瑚种群可能正在适应变暖，这与最近它们的温度上限的增加是一致的。

期刊介绍： Nature Climate Change is dedicated to addressing the scientific challenge of understanding Earth's changing climate and its societal implications. As a monthly journal, it publishes significant and cutting-edge research on the nature, causes, and impacts of global climate change, as well as its implications for the economy, policy, and the world at large. The journal publishes original research spanning the natural and social sciences, synthesizing interdisciplinary research to provide a comprehensive understanding of climate change. It upholds the high standards set by all Nature-branded journals, ensuring top-tier original research through a fair and rigorous review process, broad readership access, high standards of copy editing and production, rapid publication, and independence from academic societies and other vested interests. Nature Climate Change serves as a platform for discussion among experts, publishing opinion, analysis, and review articles. It also features Research Highlights to highlight important developments in the field and original reporting from renowned science journalists in the form of feature articles. Topics covered in the journal include adaptation, atmospheric science, ecology, economics, energy, impacts and vulnerability, mitigation, oceanography, policy, sociology, and sustainability, among others.
