全球开花物候随温度升高而变化，但长期观测和温度记录同时发生的罕见现象阻碍了对许多物种和大空间尺度上物候响应性的评估。我们利用植物标本馆标本结合历史温度数据，研究了气候变化对北美中北部11.6万平方公里141种植物开花趋势的影响。平均而言，最大花期提前2.4天°C - 1，尽管物种特异性响应在−13.5至+ 7.3天°C - 1之间变化。植物的功能类型在物候响应方面表现出明显的差异，在本地种和引种种、开花季节、风传粉种和生物传粉种之间存在显著差异。该研究首次评估了具有广泛物种代表性的大尺度物候响应模式，是了解当前和未来气候变化对物种性能和生物多样性影响的重要一步。
Shifting flowering phenology with rising temperatures is occurring worldwide, but the rarity of co-occurring long-term observational and temperature records has hindered the evaluation of phenological responsiveness in many species and across large spatial scales. We used herbarium specimens combined with historic temperature data to examine the impact of climate change on flowering trends in 141 species collected across 116,000 km2 in north-central North America. On average, date of maximum flowering advanced 2.4 days °C−1, although species-specific responses varied from − 13.5 to + 7.3 days °C−1. Plant functional types exhibited distinct patterns of phenological responsiveness with significant differences between native and introduced species, among flowering seasons, and between wind- and biotically pollinated species. This study is the first to assess large-scale patterns of phenological responsiveness with broad species representation and is an important step towards understanding current and future impacts of climate change on species performance and biodiversity.
