Current environments and evolutionary history shape forest temporal assembly

Understanding the drivers of species temporal assembly is increasingly important, as climate change shifts the timing of species phenologies (life cycle events) globally. We performed a controlled environment study on the temperature and daylength cues driving woody plant budburst across North America. This dataset includes 47 species from four populations, two in eastern North America and two in western North America. Applying a phylogenetic Bayesian model we tested for species-level and community-level differences in cues responses and the effects of evolutionary history.探究物种时间组配的驱动机制愈发重要，因气候变化已在全球范围内改变物种物候（生命周期事件）的发生时序。我们针对北美全域木本植物芽萌动的温度与日照长度调控因子开展了控制环境实验。本数据集涵盖来自4个种群的47个物种，其中北美东部与西部各2个种群。我们采用系统发育贝叶斯模型（phylogenetic Bayesian model），检验了物种水平与群落水平上的调控因子响应差异，以及进化历史的影响效应。
