许多植物的种子生产具有年际变化大的特点，某些物种在次大陆尺度上是同步的，而另一些物种在局部尺度上是同步的。生殖同步性影响动物迁徙、对资源脉动的营养反应以及管理和保护的规划。生殖的空间同步性通常归因于莫兰效应，但仅凭这一点无法解释同步性的种间差异。研究表明，种间种子产量与天气关系的保存差异与Moran效应相结合，可以解释生殖同步的变化。保守的天气信号时间可以让种群在1000公里的距离上保持同步。相反，如果种群对变化的天气信号作出反应，则无法实现同步。我们的研究表明，物种在其天气线索的时空保守程度上存在差异，这具有重要的后果，包括对气候变化的脆弱性的种间差异。
Seed production in many plants is characterized by large interannual variation, which is synchronized at subcontinental scales in some species but local in others. The reproductive synchrony affects animal migrations, trophic responses to resource pulses and the planning of management and conservation. Spatial synchrony of reproduction is typically attributed to the Moran effect, but this alone is unable to explain interspecific differences in synchrony. We show that interspecific differences in the conservation of seed production-weather relationships combine with the Moran effect to explain variation in reproductive synchrony. Conservative timing of weather cues that trigger masting allows populations to be synchronized at distances >1000 km. Conversely, if populations respond to variable weather signals, synchrony cannot be achieved. Our study shows that species vary in the extent to which their weather cueing is spatiotemporally conserved, with important consequences, including an interspecific variation of masting vulnerability to climate change.
