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.

随着气候变化在全球范围内改变了物种物候（即生命周期事件）的发生时序，理解物种时间群落构建的驱动因子愈发重要。本研究针对北美地区木本植物芽萌发的温度与日长调控因子，开展了控制环境实验。本数据集包含来自4个种群的47个物种，其中北美东部与西部各分布2个种群。本研究采用系统发育贝叶斯模型，检验了物种水平与群落水平上的调控因子响应差异，以及进化历史所产生的影响。
