入侵物种对世界各地的许多生态系统构成严重的生态威胁，并为研究快速适应和进化提供了独特的机会。遗传变异使生物种群在进化的时间范围内既健壮又能适应不同的环境条件。相比之下，入侵动物可以迅速适应新的环境，遗传多样性最小。因此，环境效应能够触发表观遗传反应的程度对于理解表观遗传学在快速适应中的作用特别有趣。在这篇综述中，我们简要概述了控制基因表达的不同表观遗传学机制，并强调了表观遗传学对环境适应的重要性。我们还讨论了最近的出版物，这些出版物为表观遗传机制在环境适应中的作用提供了重要的例子。此外，我们提出了关于表观遗传调节作为入侵物种的适应策略的当前知识的概述。一个特别有趣的例子是大理石纹小龙虾，这是一种新颖的、克隆的淡水小龙虾物种，在几年内定居在不同的栖息地。最后，我们解决了当前方法的重要局限性，并强调了不太为人所知的非遗传生物适应机制的潜在重要性。
Invasive species represent a serious ecological threat for many ecosystems worldwide and provide a unique opportunity to investigate rapid adaptation and evolution. Genetic variation allows populations of organisms to be both robust and adaptable to different environmental conditions over evolutionary timeframes. In contrast, invasive animals can rapidly adapt to new environments, with minimal genetic diversity. Thus, the extent to which environmental effects can trigger epigenetic responses is particularly interesting for understanding the role of epigenetics in rapid adaptation. In this review, we provide a brief overview of the different epigenetic mechanisms that control gene expression, and emphasize the importance of epigenetics for environmental adaptation. We also discuss recent publications that provide important examples for the role of epigenetic mechanisms in environmental adaptation. Furthermore, we present an overview of the current knowledge about epigenetic modulation as an adaptive strategy for invasive species. A particularly interesting example is provided by the marbled crayfish, a novel, monoclonal freshwater crayfish species that has colonized diverse habitats within a few years. Finally, we address important limitations of current approaches and highlight the potential importance of less well-known mechanisms for non-genetic organismal adaptation.
