Vinton等人[1]通过关注现有的基因型敏感性是否会增加或减少进化反应的速率，根据当地环境变异性和环境状态之间的自相关性，提出了理解塑料对气候变化的反应的重要问题。他们的观点强调在评估气候变化下演变的可能性和程度时，环境可变性和可预测性之间的相互作用。在评估可塑性和进化在应对气候变化中的作用时，需要考虑响应发生的环境背景的特定方面，例如[2-5]。除了环境差异，可塑性反应的两个基本组成部分是它们的可逆性和基因型对环境线索的敏感性，同时组装可塑性反应的持续时间。这两种成分都与发育密切相关，因为不太可逆（但可能更深刻）的可塑性表型变化通常在发育早期确定，而更可逆的变化通常不受发育限制，但需要在敏感性和持久性方面进行更大的投资。我们认为，随着环境变得更加多变和不可预测，塑料反应的准确性和幅度之间的这种权衡对于确定种群持久性至关重要。
Vinton et al [1] raise important issues in understanding plastic responses to climate change, by focusing on whether existing genotypic sensitivities increase or decrease rates of evolutionary response, depending on local environmental variability and the autocorrelation between environmental states. Their perspective emphasizes interactions between environmental variability and predictability when assessing the likelihood and magnitude of evolution under climate change. We point to a framework for further understanding these interactions.In assessing the role of plasticity and evolution in responding to climate change, specific aspects of the environmental context wherein responses occur need to be considered, eg [2-5]. Alongside environmental variance, two fundamental components of plastic responses are their reversibility and the duration of genotypes’ sensitivity to environmental cues while assembling plastic responses. Both components are closely tied to development, in that less reversible (but potentially more profound) plastic phenotypic changes are often determined early in development, whereas more reversible changes are often less developmentally constrained but demand greater investment in sensitivity and persistence. We think that such a trade-off between the accuracy and magnitude of plastic responses is critical in determining population persistence as environments become more variable and unpredictable.
