人们越来越关注气候变化和海洋酸化对海洋生物和生态系统的影响，但人们对适应和适应这些威胁的潜力知之甚少。尽管许多短期实验报告了海洋变暖和酸化的负面生物影响，但新的研究表明，一些海洋物种有能力世代适应更温暖和更酸性的环境。因此，跨代可塑性可能是一种强大的机制，某些物种的种群将能够适应预计的气候变化。在这里，我回顾了了解鱼类跨代适应的最新进展。过去两到三年的研究表明，跨代适应可以部分或完全改善一系列不同物种的变暖、酸化和缺氧的负面影响。目前尚不清楚支持跨代适应的分子和细胞途径，但现代遗传方法提供了探索这些机制的工具。尽管跨代适应具有潜在的好处，但跨代反应的表型特征可能存在局限性，并且需要研究生命阶段之间的权衡。未来的研究还应该测试跨代可塑性和遗传进化之间的潜在相互作用，以确定这两个过程将如何在未来几十年内形成对环境变化的适应性反应。
There is growing concern about the impacts of climate change and ocean acidification on marine organisms and ecosystems, yet the potential for acclimation and adaptation to these threats is poorly understood. Whereas many short-term experiments report negative biological effects of ocean warming and acidification, new studies show that some marine species have the capacity to acclimate to warmer and more acidic environments across generations. Consequently, transgenerational plasticity may be a powerful mechanism by which populations of some species will be able to adjust to projected climate change. Here, I review recent advances in understanding transgenerational acclimation in fishes. Research over the past 2 to 3 years shows that transgenerational acclimation can partially or fully ameliorate negative effects of warming, acidification, and hypoxia in a range of different species. The molecular and cellular pathways underpinning transgenerational acclimation are currently unknown, but modern genetic methods provide the tools to explore these mechanisms. Despite the potential benefits of transgenerational acclimation, there could be limitations to the phenotypic traits that respond transgenerationally, and trade-offs between life stages, that need to be investigated. Future studies should also test the potential interactions between transgenerational plasticity and genetic evolution to determine how these two processes will shape adaptive responses to environmental change over coming decades.
