季节性生活史事件的时间被假定为进化以使生命周期与资源的可用性同步。繁殖时间的时间变化可能对后代产生严重的适应性后果，但成人生殖决策和后代表型之间的相互作用仍然知之甚少。跨代可塑性（TGP）是一种潜在的机制，允许对环境变化的快速反应。在这里，我们调查，如果实验延迟育种诱导TGP在摩尔蛙（蛙arvalis）的幼虫生活史特征。我们发现了明确的证据TGP在育种物候变化的反应：延迟育种增加后代的发育和生长速度在没有外部线索。这构成了三峡工程对脊椎动物繁殖物候变化反应的第一个明确证据。三峡工程可以发挥重要作用，在调整后代的生活史策略，他们最有可能遇到的环境，并可能构成一个重要的机制，应对气候变化。
The timing of seasonal life-history events is assumed to evolve to synchronize life cycles with the availability of resources. Temporal variation in breeding time can have severe fitness consequences for the offspring, but the interplay between adult reproductive decisions and offspring phenotypes remains poorly understood. Transgenerational plasticity (TGP) is a potential mechanism allowing rapid responses to environmental change. Here, we investigated if experimentally delayed breeding induces TGP in larval life-history traits in the moor frog (Rana arvalis). We found clear evidence of TGP in response to changes in breeding phenology: delayed breeding increased offspring development and growth rates in the absence of external cues. This constitutes the first unequivocal evidence for TGP in response to changes in breeding phenology in vertebrates. TGP can play an important role in adjusting offspring life-history strategies to the environment they are most likely to encounter, and may constitute an important mechanism for coping with climate change.
